Three-Phase Heterojunction NiMo-Based Nano-Needle for Water Splitting at Industrial Alkaline Condition
文献摘要：
Constructing heterojunction is an effec-tive strategy to develop high-performance non-precious-metal-based catalysts for electrochemical water splitting(WS).Herein,we design and prepare an N-doped-car-bon-encapsulated Ni/MoO2 nano-needle with three-phase heterojunction (Ni/MoO2@CN) for accelerating the WS under industrial alkaline condition.Density functional theory calculations reveal that the electrons are redistrib-uted at the three-phase heterojunction interface,which optimizes the adsorption energy of H-and O-containing intermediates to obtain the best △GH* for hydrogen evo-lution reaction (HER) and decrease the △G value of rate-determining step for oxygen evolution reaction (OER),thus enhancing the HER/OER catalytic activity.Elec-trochemical results confirm that Ni/MoO2@CN exhibits good activity for HER (η-10 =33 mV,η-1000 =267 mV)and OER (η10=250 mV,η1000 =420 mV).It shows a low potential of 1.86 V at 1000 mA cm-2 for WS in 6.0 M KOH solution at 60 ℃ and can steadily operate for 330 h.This good HER/OER performance can be attributed to the three-phase heterojunction with high intrinsic activity and the self-supporting nano-needle with more active sites,faster mass diffusion,and bubbles release.This work provides a unique idea for designing high efficiency catalytic materials for WS.
