Carbon dioxide’s influence on world warming is an issue that ought to be addressed within the shortest time period doable for the well-being of Earth’s ecosystem and humanity. Amongst others, the diminution of atmospheric CO2 focus by its conversion is a horny various. Furthermore, this valorisation methodology may result in the formation of value-added compounds reminiscent of carbon monoxide, methanol or methane. Thermal hydrogenation might be probably the most mature methodology to attain this objective. Nevertheless, this response shouldn’t be thought-about solely because the discount of CO2, however have to be conceptualised because the conversion of carbon dioxide and hydrogen to value-added compounds and water. In that case, the supply of hydrogen can’t be ignored. As a result of excessive stability of the carbon dioxide molecule, its discount by thermal hydrogenation requires a catalyst. To be industrially related, the designed supplies ought to current excellent efficiency and stability with almost full selectivity within the case of CO and CH4. This contribution compiles the latest materials developments for every response, together with discussions of their behaviour and comparability of performances.
