Abstract:

With the continuous increase of carbon dioxide(CO2) emissions, the impact of global warming and climate change on human life and ecological environment has become more serious. As a cheap and renewable carbon and oxygen resource, converting CO2 into high value-added chemicals is one of the shining research topics in the field of green chemistry and energy, and has received extensive attention. The Pd-based catalysts are one kind of the most promising catalysts of CO2 catalytic conversion due to its excellent hydrogenation capacity, good stability, anti- sintering and anti-poisoning properties. This paper will review the research progress of the hydrogenation of CO2 over Pd-based catalysts to synthesis small energy molecule compounds such as HCOOH, CO, CH4 and methanol. We will pay main attention to the discussion of the active sites for the adsorption/activation of CO2 molecule, strong metal- support interaction, surface and interface composition, which affect the activity and selectivity of Pd-based catalysts, as well as the catalytic mechanism over Pd-based catalysts.

Key words: Pd-based catalyst, CO2 hydrogenation, Active site, Strong metal-support interactions, Catalytic mechanism
