摘要

The utilization of carbon dioxide (CO2) as a soft oxidant and promoter is a promising concept for industrial applications. The utilization of CO2 as a chemical feedstock to produce other value-added chemicals is highly preferred in green processing because of its non-toxicity, availability cost-effectiveness, and favoring reaction pathways by stabilization of intermediates and suppressing the formation of by-products thereby improving selectivity for the desired product improving yield. This review is limited to the utilization of CO₂ as a green and soft oxidant, focusing on its interaction with metal-based catalytic systems. The findings suggest that CO₂ highly contributes to improved reaction efficiencies as a promoter, its utilization is a strategy for mitigation of its emission into the atmosphere, and it’s in line with the principles of green chemistry by minimizing the generation of harmful by-products. This review underscores the potential of CO₂ as a sustainable promoter and soft oxidant in catalytic oxidation reactions, paving the way for environmentally benign industrial processes.
