主  题:Wood membrane Hierarchical structures Electrocatalysis:Hydrogen generation 

摘      要:Porous biomass electrodes have emerged as a critical material for electrocatalytic hydrogen evolution reaction(HER).However,most approaches for synthesizing porous electrodes from biomass require high energy consumption,which is resulted from the smash of biomass and the undergoing of serial ***,a self-supported wood-derivedbreathablemembrane is utilized directly as electrodes for highefficient HER via an assembly of Fe-doped NiP *** well-designed hierarchical porous structures in natural wood membrane(NWM)are unusually beneficial for electrolytes accessibility and hydrogen gas *** obtained wood-derived membrane exhibits a high electrocatalytic activity and good cycling durability in acidic and alkaline ***,the Fe_(0.074) NiP alloys/NWM electrode affords a large current density of 100 m A cm^(-2) at extremely low overpotentials of 168 mV in acidic electrolyte and174 m V in alkaline *** functional theory calculations unveil that the Fe atom doped in NiP alloys can create much more charge accumulation around Fe and Ni active sites,which helps decrease the △GH_(*)and △G_(H2O)and significantly promote the HER *** new insight will promote further explorations of economic,high-efficient,and biodegradable wood-derived electrocatalysts for HER.
