| 摘 要： | 近年来,利用可再生能源分解水制氢进而开展二氧化碳资源化利用的研究引起了学术界和工业界的极大兴趣.科学层面上它暗合了自然光合作用的理念;应用层面上它把二氧化碳变废为宝,既可以得到人类必需的含碳化学品,又可以实现碳中和.甲醇被认为是二氧化碳资源化的最佳选择,可在动力、交通、化工等领域替代煤炭等传统化石能源,也是良好的载氢分...

| Abstract: | The conversion of CO2 to methanol with high activity and high selectivity remains challenging owing to the kinetic and thermodynamic limitations associated with the low chemical reactivity exhibited by CO2.Herein,we report a novel Cd/TiO2 catalyst exhibiting a methanol selectivity of 81%,a CO2 conversion of 15.8%,and a CH4 selectivity below 0.7%.A combination of experimental and computational studies revealed that the unique electronic properties exhibited by the Cd clusters supported by the TiO2 matrix were responsible for the high selectivity of CO2 hydrogenation to methanol via the HCOO*pathway at the interfacial catalytic sites. |
