Review demonstrates progress in catalytic routes for converting carbon dioxide into acetic acid, highlighting sustainable alternatives to fossil-based chemical synthesis.
Acetic acid (AA) has a growing market with wide applications within the food industry and chemical intermediates. Conventional AA production processes rely heavily on fossil‐based feedstocks and noble metal catalysts, resulting in high energy consumption and cost with poor environmental sustainability. Synthesis of AA using CO 2 is of great importance and presents a promising avenue for addressing environmental challenges and advancing sustainable energy solutions. In this short review, we systematically summarize and discuss the development of AA synthesis from CO 2 since the 1990s, and we manage to provide an in‐depth analysis of the recent evolutions and corresponding catalytic systems for AA production from CO 2 . The review scrutinizes three ways (four routes) for the conversion of CO 2 to AA, catalytic systems and reaction mechanisms, and offers a future direction for harnessing CO 2 conversion to AA. Readers can acquire a thorough grasp of AA synthesis from CO 2 , revealing its promise as a sustainable route for chemical synthesis.
