| Abstract |
Vast and exceeding emissions derived from human activities related to fossil fuels have led to an excessive concentration of carbon dioxide (CO2) in the atmosphere with concomitant problems in the environment. To mitigate the resulting harmful effects, CO2 conversion to valuable fuels and precursors have become an urgent need. Recently the design of new cost-effective catalysts able to produce CO and CH3OH from CO2 is a chief challenge. In the current search for new catalysts, transition-metal carbides are appealing as an alternative to novel metals for many reactions due to their abundance, relatively low cost, and, apparently, smaller activation energy barriers for reactions such as for O−O bond cleavage. In the present work, we developed a general and straightforward strategy for the synthesis of molybdenum carbide (MoC) nanospheres by laser ablation of metal oxide in acetone. Crucially, this approach is green, facile, catalyst-free, and especially can be operated under ambient environments. Furthermore, we synthesized metal-MoC hybrid nanostructures that are theoretically predicted to be high activity, selectivity, and stability for the reduction of CO2 to CO with some subsequent selective hydrogenation toward methanol. This green catalytic transformations are very attractive, and promising to overcome low conversion percentages and selectivity reduction of CO2. |
