这篇文章的主要内容以及亮点:
由于环保要求(CO2是最基本的温室气体),an instantaneous response for research studies in the chemistry of CO2 including its activation,utilization, and fixation is urgently needed.
目前主要措施:
但是CO2活化存在一定的问题、难度:
Most previous attempts were unable to attract industrial attention as they suffer from either the use of expensive but non-robust homogeneous catalysts or the use of peculiar reaction conditions (requires excess ligand(s) and solvents at extreme conditions).
本文主要工作:
结论:
To conclude, it is demonstrated that, with introduction of methanol to the Pd/Cu/ZnO nanocatalyst under H2/CO2, carbon dioxide can be activated and fixed as methyl formate with impressive TOF, yield, and selectivity. Thus, a new route for CO2 activation by heterogeneous means at ambient conditions is described. This preliminary study also offers directions to rationally design and optimize the required catalyst, reactor, and experimental conditions for this reaction.
