Uncovering the critical function of lanthanum in CH₄ production from CO₂ using exsolved LaNiO₃ perovskite catalysts

Abstract

CO2 methanation, also known as Sabatier reaction, is of great environmental interest as a sustainable process for energy production and storage. Herein, we report the development of a Ni-La2O3 catalyst...

Deciphering Local Structural Complexity in Zn/Ga-ZrO2 CO2 Hydrogenation Catalysts

“…Following the challenge of high-impact CO 2 conversion, several research groups are investing massive effort in the development of new catalysts capable of converting carbon dioxide into high-value products such as CH 3 OH, formaldehyde, methane, hydrocarbons, and olefins. − For future industrial application, the developed catalysts are required to withstand high-temperature and high-pressure conditions, often in a steam-rich environment. These harsh conditions are also associated with the presence of an acidic zeolite/zeotype in the case of tandem catalysts for the direct conversion of CO 2 to hydrocarbons. − The common denominator of these studies is to find the right combination of guest atom and concentration that leads to higher catalytic activity, which often implies a systematic trial-and-error approach by screening several elements.…”
