Hydrogen　peroxide　(H2O2)　is　a　versatile　and　environmentally　friendly　oxidant　with　a　wide　range　of　industrial　and　household　applications.　In　recent　years,　the　decentralization　of　H2O2　production　through　the　two-electron　oxygen　reduction　reaction　(ORR)　has　emerged　as　an　attractive　alternative　to　the　well-established　anthraquinone　process.　And　of　the　many　electrocatalysts　developed　for　the　two-electron　ORR　to　produce　H2O2,　metal-free　carbon　catalysts　(MFCCs)　have　received　extensive　attention　due　to　their　cost-effectiveness　and　natural　abundance.　Based　on　this,　this　review　will　provide　an　in-depth　overview　into　MFCC　design　and　fabrication　with　an　emphasis　on　porosity　control,　heteroatom　doping,　oxygen　functionalization,　defect　engineering　and　organic-inorganic　interface　engineering.　This　review　will　also　discuss　and　analyze　the　interplays　between　these　factors　in　terms　of　MFCC　catalytic　activity　and　selectivity　towards　H2O2　production.　Furthermore,　major　technical　challenges　are　presented,　and　future　research　directions　are　proposed　to　guide　further　development　towards　practical　application.
