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.

用于高效制氢的介孔 Pt/N-TiO2/Ti 光催化板

整体式板式光催化剂具有优异的光吸收、丰富的活性位点和强的机械附着力，是光催化应用的增长趋势，就像光伏电池板一样。在这项研究中，我们报道了一种具有颗粒和介孔结构的大型Pt/N-TiO2/Ti光催化板，它表现出比纳米线和纳米片光催化剂更优异的光催化性能和附着力。 Pt/N-TiO2/Ti优异的光催化性能归因于单Pt原子助催化剂具有较大的暴露表面积、增强的光吸收、光生载流子的高分离效率以及优异的表面活性。最好的Pt/N-TiO2/Ti样品在350 nm光照射下表现出出色的光催化产氢活性（72547.9 µmol·h-1·g-1）和47.07%的高表观量子效率。可以预见，所提出的方法和见解将为优质TiO2基光催化板的开发和应用奠定坚实的基础。
