“MoS2-Pt Deposited on Nitrogen-Doped Carbon Nanotubes as Efficient Electrocatalyst for Hydrogen Evolution Reaction'(PPT)

摘要

Polymer Electrolyte Membrane (PEM) Water Electrolyzer.Hydrogen Evolution Reaction (HER):4H~+ 4e~-→ 2H2,E~0 = 0 V vs.NHE.1.Best Electrocatalyst Pt /C with η ~ 0.1.1 High-Cost and low abundance.2.Alternative Electrocatalyst:2.1 MoS2 but present high η.2.2 Pt doping,< 5 at.% Pt,to reduce η.3.Highly dispersed electrocatalyst: 3.1 Use carbon nanostructures (CNs) as support: CNT,N-MWCNT,Graphene,3.2 Synthesis in one-step: CNs + active metal.
