Mesoporous Pt/N‐TiO2 /Ti Photocatalytic Plate for Highly Efficient Hydrogen Production

Monolithic plate‐type photocatalyst with excellent light absorption, abundant active sites and strong mechanical adhesion is the growing trend of photocatalysis application, as referring to a photovoltaic panel. In this study, we report a large‐scale Pt/N‐TiO2/Ti photocatalytic plate with granular and mesoporous structure, which shows a superior photocatalytic performance and adhesion than nanowires and nanosheets photocatalysts. The outstanding photocatalytic performance of Pt/N‐TiO2/Ti is attributed to the large exposed surface area, enhanced light absorption, high separation efficiency of photogenerated carriers and excellent surface activity induced by single Pt atom cocatalyst. The best Pt/N‐TiO2/Ti sample could exhibit an outstanding photocatalytic hydrogen production activity of 72547.9 µmol·h‐1·g‐1, and a high apparent quantum efficiency of 47.07% under a 350 nm light irradiation. It can be anticipated that the proposed method and insights would pave a solid way on the development and application of superior TiO2 based photocatalytic plate.
