Single-atom catalysts have been formally developed for nearly a decade, and their work has gradually expanded from initial preparation/characterization to mechanism research.
Recently, Professor Chen Wei and Dr.
Figure 1.
Using XPS, XAS and electrochemical tester and other characterization methods to analyze Pt on four single-atom catalysts (Pt-SAs/TMDs: Pt-SAs/MoS 2 , Pt-SAs/WS 2 , Pt-SAs/MoSe 2 , Pt -SAs/WSe 2 ) valence state and electrocatalytic HER activity were characterized.
