Abstract ：
Hydrogen peroxide (H2O2) is a versatile and zero-emission material that is widely used in the industrial, domestic, and healthcare sectors. It is clear that it plays a critical role in advancing environmental sustainability, acting as a green energy source, and protecting human health. Conventional production techniques focused on anthraquinone oxidation, however, electrocatalytic synthesis has arisen as a means of utilizing renewable energy sources in conjunction with available resources like oxygen and water. These strides represent a substantial change toward more environmentally and energy-friendly H2O2 manufacturing techniques that are in line with current environmental and energy goals. This work reviews recent advances in two-electron water oxidation reaction (2e-WOR) electrocatalysts, including design principles and reaction mechanisms, examines catalyst design alternatives and experimental characterization techniques, proposes standardized assessment criteria, investigates the impact of the interfacial milieu on the reaction, and discusses the value of in situ characterization and molecular dynamics simulations as a supplement to traditional experimental techniques and theoretical simulations, as shown in Figure 1. The review also emphasizes the importance of device design, interface, and surface engineering in improving the production of H2O2. Through adjustments to the chemical microenvironment, catalysts can demonstrate improved performance, opening the door for commercial applications that are scalable through tandem cell development.

Abstract ：
Nanosized Pd-based catalysts are widely used in the direct hydrogen peroxide (H2O2) synthesis from H-2 and O-2, while the selectivity and yield of H2O2 remain inferior. Here, a remarkable H2O2 yield of 115 mol/g(Pd)/h and H2O2 selectivity higher than 99% are reported using a Pd single-atom catalyst for the direct synthesis of H2O2. Nanosized palladium (Pd)-based catalysts are widely used in the direct hydrogen peroxide (H2O2) synthesis from H-2 and O-2, while its selectivity and yield remain inferior because of the O-O bond cleavage from both the reactant O-2 and the produced H2O2, which is assumed to have originated from various O-2 adsorption configurations on the Pd nanoparticles. Herein, single Pd atom catalyst with high activity and selectivity is reported. Density functional theory calculations certify that the O-O bond breaking is significantly inhibited on the single Pd atom and the O-2 is easier to be activated to form *OOH, which is a key intermediate for H2O2 synthesis; in addition, H2O2 degradation is shut down. Here, we show single Pd atom catalyst displays a remarkable H2O2 yield of 115 mol/g(Pd)/h and H2O2 selectivity higher than 99%; while the concentration of H2O2 reaches 1.07 wt.% in a batch.

Abstract ：
Developing oxide supports for stabilizing single-atom catalysts enables more flexibility for tuning the electronic metal-support interactions (EMSIs) toward better catalytic activities. However, due to the electronegativity of oxygen anions, single-metal atoms often remain positively charged in these oxide supports and are poor at binding hydrogen species for the hydrogen evolution reaction (HER). Here, we report a ligand charge donation-acquisition balance strategy via an amorphous TiBxOy support to tune the EMSIs, which lead to the boosted HER mass activity of a single Pt atom catalyst. Based on spectroscopic characterizations, we found that Pt single atoms preferentially bonded with nearly neutral B atoms originating from TiB2-like species in the Ti-B-O framework rather than O anions. Density functional theory calculations reveal that due to the charge-transfer balance between B-O and B-Pt, the nucleophilicity of Pt was tuned to an optimum state, with an ideal hydrogen binding energy that benefits the HER. As a result, this Pt/TiBxOy catalyst achieves a high HER mass activity (37.8 A mg(-1) Pt) and a turnover frequency (33.2 H-2 s(-1) Pt site(-1)) at an overpotential of 50 mV in an acid medium, outperforming commercial Pt/C by a factor of 34 and 33, respectively.

Abstract ：
The electrochemical production of hydrogen peroxide via the two-electron (2e(-)) oxygen reduction reaction (ORR) is an environmentally friendly method and is expected to be an alternative means to the industrial anthraquinone process. It is particularly suitable for on-site and small-scale H2O2 requirements. The development of earth-abundant catalysts with high activity and selectivity toward H2O2 is highly desirable and challenging. Here, we have prepared Co3O4 with tunable oxygen vacancies (OVs) and strongly coupled it to nitrogen-doped carbon nanotubes through an exsolution strategy. The Co3O4 with a higher OV concentration exhibits a higher 2e(-) ORR activity, higher H2O2 selectivity, and lower H2O2 reduction reaction (H2O2RR) activity so that effectively improving the production rate of H2O2 (1.6 mol peroxide/gcatalyst/h at 0.0 VRHE) in acidic media. The catalyst is also used as a cathode for the electro-Fenton process and degrades up to 80% of 40 mg/L of rhodamine B solution within 25 min. Density functional theory calculation shows that the *OOH binding energy (Delta G(*OOH)) could decrease on increasing the numbers of OVs, which subsequently benefits the protonation of *OOH to generate H2O2.

Abstract ：
Innovatively designed, modified, and synthesized catalyst/electrode materials are of great importance in improving the performance of electrochemical energy devices for energy storage and conversion. Among various material modification technologies, the ion-irradiation technique has been recognized as a promising technology, which can effectively modify and design materials through controlling the key irradiation parameters, such as irradiation ion species, energy and fluence. The advantages of the ion-irradiation technique are high precision, favorable controllability, favorable repeatability, etc.; meanwhile, it can realize arbitrary element doping and defect control for many catalyst/electrode materials. Notably, it does not induce any impurities into the target materials during the ion-irradiation process, which is superior to many chemical modifications. The effects of ion-irradiation on catalyst/electrode materials in recent years are described in this review, including defect introduction, regulation of the electronic structure, morphology control, synthesis, and element doping. Then, the applications of ion irradiated catalyst/electrode materials in water electrolysis/photoelectrolysis cells, lithium-ion batteries, and supercapacitors are systematically summarized with an emphasis on the advantages of boosting the properties of materials. Finally, the challenges and strategies are proposed for developing more practical ion-irradiation techniques towards high-performance catalyst/electrode materials.

Abstract ：
New types of photocatalytic systems formed by coupling annealed large-sized NiFe-LDH nanosheets with smallsized TiO2 nanosheets were used to facilitate the rapid separation of photo-generated electrons and holes. The photocatalytic hydrogen production for optimized photocatalytic systems can reach 209 mmol/g, which is 8 times of that for TiO2. To understand the photocatalytic mechanism, in-situ annealing transmission electron microscopy (TEM) investigation of the microstructural evolution of large-sized NiFe-LDH nanosheets identified typical microstructures at different annealing stages. The microstructure of the optimized system contains plentiful ultrafine grains distributed along surface delaminated defects, which can provide abundant active sites for photocatalytic hydrogen evolution. Electrochemical and spectroscopic techniques were further used to determine the Z-scheme mechanism, guiding photo-generated electrons to fast transfer onto large-sized NiFeLDH nanosheets to achieve high efficient carrier separation.

Abstract ：
Reducing the usage of noble metals, such as platinum-based catalysts for oxygen reduction reaction (ORR) is pressingly demanded towards the practical applications of proton-exchange membrane fuel cells. One promising way is to develop Pt single atom catalysts (SACs), which, however, are plagued by their preference toward two-electron ORR pathway as well as stability issue. Herein, a single-atom alloy (SAA) catalyst with platinum-cobalt (Pt-Co) dual sites encapsulated in nitrogen-doped graphitized carbon nanotubes (Pt1Co100/N-GCNT) consisting of isolated Pt atoms decorated on the surface of Co nanoparticles was reported. Based on complementary spectroscopic characterizations and first-principle calculations, we propose that the unique Pt-Co dual sites in SAA facilitates the adsorption and dissociation of oxygen, particularly for the immobilization of OOH* intermediate and the dissociation of OH* intermediate, and thus result in high-efficiency four-electron ORR pathway. Consequently, the Pt1Co100/N-GCNT SAA catalyst achieves a mass activity of 0.81 A mg(Pt)(-1) at 0.90 V (versus the reversible hydrogen electrode) in 0.1 M HClO4 electrolyte, outperform commercial Pt/C catalyst for 5.4 times. The superior stability of the SAA catalyst was reflected by the results from the 30,000 potential-scanning cycles combined with the post characterization of the catalyst.
