| 2 | Synthesis of cobalt single atom catalyst by a solid-state transformation strategy for direct C-C cross-coupling of primary and secondary alcohols显示文摘Atomic engineering of single atom catalysts(SACs)with high-density available active sites and optimized electronic properties can substantially boost catalytic efficacy.Herein,we report a solid-state transformation strategy to access Co SACs by introducing Co species from commercial CO_(2)O3 powders into nitrogen-doped carbon support.The catalyst exhibited excellent catalytic activity,with a turnover frequency(TOF)of 2,307 h^(-1)and yield of 95%,in the direct C-C cross-coupling of benzyl alcohol and 1-phenylethanol(1 atm O2@80℃)to yield chaicone.Density functional theory(DFT)calculations demonstrate the coordination environment and electronic metal-support interaction impact the catalytic pathway.In particular,a wide substrate scope and a broad functional-group tolerance of this SAC were validated,and the employment of this strategy for large-scale synthesis was also shown to be feasible.This work might shed light on the facile and scalable synthesis of highly active,selective,and stable SACs for heterogeneous catalysis. | Zhijun Li Yuying Chen Xiaowen Lu Honghong Li Leipeng Leng Tinglei zhang JHugh Horton | 2022 | Nano Research2022，15，5： | 0 |
