The isolated Cu1+ on Cu1/TiO2 single atom catalysts (SACs) facilitated the simultaneous activation of chemisorbed O2 and 2-coordinated surface lattice O2−, which triggered the CO oxidation through E-R (80 °C) and MvK (200 °C) routes synergistically with elevated temperature. This finding provides insights and strategy for the rational design of efficient oxidation catalysts with sufficient reactive oxygen species for practical application.

单原子 Cu1/TiO2 催化剂中分子氧和表面晶格氧的双重活化用于 CO 氧化

Cu 1 /TiO 2单原子催化剂 (SAC) 上的孤立 Cu 1+促进了化学吸附的 O 2和 2 配位表面晶格 O 2−的同时活化,从而通过 ER (80 °C) 和 MvK ( 200 °C) 路线与升高的温度协同作用。这一发现为合理设计具有足够活性氧的高效氧化催化剂以供实际应用提供了见解和策略。
