Development of inorganic-based nano-electrocatalysts for highly efficient water electrolysis

Polymer electrolyte membrane water electrolysis (PEMWE) is regarded as commercial electrochemical water-splitting technology to produce clean and sustainable hydrogen fuel from renewable energy resources. But current PEMWE system requires the noble metal-based metal, such Pt, Ir or Ru, electrocatalysts, which limits large-scale commercialization of PEMWE. Thus, developing cost-effective highly active electrocatalysts important on a large scale. In this paper, we introduce our recent works develop inorganic-based noble-metal reduction noble-metal-free nano-electrocatalysts for efficient through various facile synthetic strategies. First Pt/MoC hybrid nanoparticles by hybridization MoC Pt noble-metal-reduced HER electrocatalysts. Second nickel phosphorus substituted (Co1-xNix)(S1-yPy)2/Graphene ((Co1-xNix)(S1-yPy)2/G) 3D nano-architecture, consist self-assembly 2D nanosheet, structure-engineering composition-engineering. Thrid CoP nanosheets are self-supported carbon fabric collector.
