Synthesis of Pt1/HNb3O8 Nanosheet Catalysts for Photocatalytic Hydrogen Evolution Activity
The utilization of clean solar energy for catalytic hydrogen production is currently a hot topic.A series of Pt supported on HNb3O8 nanosheet were synthesized by photo-deposition method and applied to photocatalytic hydrogen evolution.The results showed that single atom Pt1/HNb3O8 catalysts exhibited a relatively high turnover of frequency(TOF)and lager hydrogen production rate.The obtained Pt1/HNb3O8 was characterized by XRD,HRTEM,XPS,HAADF-STEM,and in-situ DRIFTS.Single-atom two-dimensional nanosheet catalysts will provide a prospective strategy to reduce the amount of precious metals and pave a new avenue for the development for highly efficient photocatalysts.
