Low-temperature hydrogenation of CO2 to methanol: progress in constructing catalytic active sites
Abstrak
Abstract In the move away from fossil fuels, methanol is viewed as a viable alternative engine fuel and hydrogen carrier, while serving as a key component in the chemical industry. In responding to the environmental impact caused by excessive CO2 emissions and the drive to promote green H2 technology, CO2 hydrogenation to produce methanol has received increasing attention, which has addressed H2 storage and transport. The reaction is thermodynamically feasible at low temperatures with a high conversion in a single pass, but there is significant scope to enhance reaction kinetics. This article reviews the progress that has been made in engineering catalytic active sites for the heterogeneous hydrogenation of CO2 to methanol at temperatures below 200 °C, including considerations of alloying effects, doping, defect formation, active site size and dispersion, coordination effects, and surface modification. The active site valence state and size in tandem with electron transfer, hydrogen spillover, and surface alkalinity/hydrophobicity can affect catalytic performance and the prevailing reaction pathway to varying degrees. The low-temperature reaction process is briefly discussed and future research directions required to further enhance catalytic efficiency are proposed.
