In chemistry, CO2 utilization plays a role to complete the redox cycle, which is intrinsically redox reactions in nature. Charge transfer is the key step for the occurrence of the reactions. Moreover, charge transfer capability is critical for developing the related catalytic materials. As for CO utilization, the selective control becomes the key issue for syngas conversion into fuels or chemicals. Herein, nano/sub-nano catalysis plays a key role in the development of new technologies for CO2 and CO utilization, and four key factors play the key role for selective catalysis, i.e. size, surface, surrounding and scale. Reaction network during syngas conversion concerning CO2 and CO utilization demonstrate the importance of C-O bond activation by nano/sub-nano catalysis with respect to the factors above mentioned.
Based on those fundamental research concerning the nature of active site, reaction network and structure-performance relationship, both catalysts and process are being developed for XTL&C with non-ASF product distribution from tunable syngas composition via multiple methane reforming.
