Jia, Henglei Du, Aoxuan Zhang, Han Yang, Jianhua Jiang, Ruibin Wang, Jianfang Zhang, Chun-yang Site-Selective Growth of Crystalline Ceria with Oxygen Vacancies on Gold Nanocrystals for Near-Infrared Nitrogen Photofixation Site-selective growth of crystalline semiconductors on gold nanocrystals remains a great challenge because of the difficult control of both nucleation and growth dynamics as well as the easy agglomeration and deformation of gold nanocrystals at high temperatures of 400–1000 °C. Here we report a facile wet-chemistry route for the selective growth of crystalline ceria at the ends of gold nanorods (Au NRs) in the presence of a small amount of bifunctional K<sub>2</sub>PtCl<sub>4</sub>. Due to the smaller steric hindrance at the ends than at the side surface, K<sub>2</sub>PtCl<sub>4</sub> may preferentially adsorb at the ends of Au NRs, triggering the autoredox reaction with the ceria precursor to obtain crystalline CeO<sub>2</sub> at the ends. Notably, the surface of grown ceria is rich in oxygen vacancies (OVs) that facilitate the adsorption and activation of N<sub>2</sub> molecules. The unique structure, the plasmon-induced hot carriers and the OVs make the obtained Au/end-CeO<sub>2</sub> an excellent catalyst for nitrogen photofixation under near-infrared (NIR) illumination. bifunctional K 2 PtCl 4;NIR;OV;N 2 molecules;NR;K 2 PtCl 4;surface;gold nanocrystals;Near-Infrared Nitrogen Photofixation Site-selective growth;ceria 2019-03-22
