Energy & Fuels, Journal Year: 2024, Volume and Issue: 38(10), P. 8481 - 8515

Published: April 24, 2024

CO2 is an important component of the atmosphere that helps in balancing Earth's atmospheric temperature and channelizes food cycles. However, increase or decrease concentration will severely affect climate. Particularly, rise levels has immensely contributed to global warming, resulting elevated temperature, altered precipitation patterns, glacier melting, subsequent rises sea levels, impacting human well-being. In response, researchers are exploring strategies capture convert into valuable products, such as methanol, formic acid, organic compounds. synthesis compounds using CO2, like benzimidazole quinazolines, a high impact. Benzimidazole, widely used medicinal chemistry for treating cancer stomach ulcers, also exhibits antiviral antifungal properties. Quinazoline derivatives, essential drugs prazosin doxazosin, have applications post-traumatic stress disorder Alzheimer's disease. These were synthesized mainly environmentally harmful synthons phosgene potassium cyanide. To address both environmental health concerns, delving chemical fixation sustainable green production. Catalysis emerges key principle chemistry, with catalysts reducing activation energy facilitating processes. This review discusses recent state art on development various conversion quinazoline benzimidazole, through homogeneous heterogeneous catalysts.
