Recent Progress in Chemically Functionalized Heterogeneous Catalysts for CO2 Conversion by Electro and Photocatalysis: A Review

Abstract

AbstractThe foremost cause of global warming in 21st century is excessive generation of CO2 and its build‐up in atmosphere. In mandate to address this important problem, many solutions are investigated, with CO2 conversion emerging as a key approach. This method produces clean, renewable energy while simultaneously lowering CO2 levels. In order to facilitate an investigation of sophisticated multifunctional catalysts for CO2 conversion, this study starts by looking at the primary sources of CO2 and their effects on the environment. It explores the importance of multifunctional catalysts and their development methods for the conversion of CO2 into value‐added products including methanol, ethanol, and hydrocarbons. Specifically, the utilization of tailored carbon‐based, metal organic frameworks (MOF)‐based, Metal Oxide‐based, Zeolite‐based catalysts, and their composites across various methods such as photocatalysis, and electrocatalysis is explored. This study attempts to highlight the difficulties and possible future developments in CO2 conversion in order to highlight the complexity of the topic. It provides an inclusive exploration of the various facets of CO2 conversion, highlighting the significance of novel catalyst development and application tactics in halting global warming.
