摘要
利用太阳能光催化制氢是目前的一个热门课题.采用光沉积法合成了一系列不同担载量的Pt/HNb3O8 纳米片催化剂,并将其应用于光催化析氢.结果表明,单原子Pt1/HNb3O8 催化剂具有较高的TOF值和较高的产氢速率.通过XRD、HRTEM、XPS、HAADF-STEM和原位DRIFTS对所得Pt1/HNb3O8 进行了表征.单原子二维纳米片催化剂可以减少贵金属含量,为开发高效光催化剂开辟了新策略.
Abstract
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.
