In-situ doping-induced lattice strain of NiCoP/S nanocrystals for robust wide pH hydrogen evolution electrocatalysis and supercapacitor
文献摘要：
Developing high-efficiency multifunctional nanomaterials is promising for wide pH hydrogen evolution reaction(HER)and energy storage but still challenging.Herein,a novel in-situ doping-induced lattice strain strategy of NiCoP/S nanocrystals(NCs)was proposed through using seed crystal conversion approach with NiC02S4 spinel as precursor.The small amount of S atoms in NiCoP/S NCs perturbed the local electronic structure,leading to the atomic position shift of the nearest neighbor in the protocell and the nanoscale lattice strain,which optimized the H* adsorption free energy and activated H2O mole-cules,resulting the dramatically elevated HER performance within a wide pH range.Especially,the NiCoP/S NCs displayed better HER electrocatalytic activity than comical 20％Pt/C at high current density in 1 M KOH and natural seawater:it only needed 266 mV vs.reversible hydrogen electrode(RHE)and 660 mV vs.RHE to arrive the current density of 350 mA cm-2 in 1 M KOH and natural seawater,indicating the application prospect for industrial high current.Besides,NiCoP/S NCs also displayed excellent super-capacitor performance:it showed high specific capacity of 2229.9 F g-1 at 1 A g-1 and energy density of 87.49 Wh kg-1,when assembled into an all-solid-state flexible device,exceeding performance of most transition metal phosphides.This work provides new insights into the regulation in electronic structure and lattice strain for electrocatalytic and energy storage applications.
