Strain　engineering　of　electrocatalysts　provides　an　effective　strategy　to　improve　the　intrinsic　catalytic　activity.　Here,　the　defect-rich　crystalline/amorphous　Pd　nanosheet　aerogel　with　hybrid　microstrain　and　lattice　strain　is　synthesized　by　combining　laser　irradiation　and　phosphorus　doping　methods.　The　surface　strain　exhibited　by　the　microstrain　and　lattice　strain　shifts　the　d-band　center　of　the　electrocatalyst,　enhancing　the　adsorption　of　intermediates　in　the　ethanol　oxidation　reaction　and　thus　improving　the　catalytic　performances.　The　measured　mass　activity,　specific　activity　and　C1-path　selectivity　of　the　Pd　nanosheet　aerogel　are　4.48,　3.06,　and　5.06　times　higher　than　those　of　commercial　Pd/C,　respectively.　These　findings　afford　a　new　strategy　for　the　preparation　of　highl　activity　and　C1　pathway　selective　catalysts　and　provide　insight　into　the　catalytic　mechanism　of　strain-rich　heterojunction　materials　based　on　tunable　surface　strain　values.
