Phosphorus Defect Mediated Electron Redistribution to Boost Anion Exchange Membrane‐Based Alkaline Seawater Electrolysis
Qingdao University of Science and Technology · China University of Petroleum, East China
Abstract
Abstract It is of essential importance to design bifunctional electrocatalysts with excellent performance for both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) in seawater splitting. Herein, an approach for manipulating electron redistribution in NiCoP treated by P defect (P v ) engineering (NiCoP v @NF) is presented, exhibiting excellent catalytic activities and stability toward HER/OER in alkaline seawater solution. The P v reduces the surface electrooxidation reconfiguration energy barrier, making it easier to drive the local conversion of crystals to active oxy(hydroxide) in OER. In addition, the Ni site of NiCoP v and the Co site of NiCoOOH are the active sites for HER and OER…
