Sunlight-driven hydrogen production from water splitting, assisted with the commonly used Pt/TiO2 catalyst, is a promising way to store clean and renewable energy. However, the photocatalytic activity of Pt/TiO2 is limited owing to the agglomeration of Pt atoms. Herein, we successfully synthesized a Pt/TiO2 catalyst, where Pt is atomically and selectively dispersed on the (1 0 1) facets of nanosized TiO2 single crystals. A remarkably higher photocatalytic activity for H2 evolution together with a considerable stability was observed as compared to commonly used Pt/TiO2. This study demonstrates a promising way to achieve atomically dispersed highly-active catalyst for water splitting.

原子分散在特定TiO 2面上的Pt,用于光催化H 2的释放
由水分解产生的阳光驱动的氢气,再加上常用的Pt / TiO 2催化剂,是一种存储清洁和可再生能源的有前途的方法。然而,由于Pt原子的团聚,Pt / TiO 2的光催化活性受到限制。在这里,我们成功地合成了一种Pt / TiO 2催化剂,其中Pt原子且选择性地分散在纳米级TiO 2单晶的(1 0 1)面上。与常用的Pt / TiO 2相比,观察到H 2析出的光催化活性显着提高,并且具有相当大的稳定性。这项研究证明了一种有前途的方法可以实现原子分散的高活性水分解催化剂。
