Electrochemical Recycling of CO2: Environmental and Industrial Significance

One promising strategy for reducing greenhouse gas emissions while creating useful chemicals and fuels is the electrochemical recycling of CO2. Recent developments in electrochemical CO2 reduction (ECR) technologies are examined in this work, with a focus on their industrial and environmental importance. CO2 can be converted into methanol, formic acid, and other commercial chemicals using electrochemical pathways, such as electrocatalytic and bioelectrochemical techniques. According to life-cycle studies, ECR provides a sustainable substitute for processes that rely on fossil fuels and can considerably lower the potential for global warming when driven by renewable electricity. Furthermore, solar-powered electrochemical pathways improve energy efficiency by combining the use of CO2 with renewable energy sources. Notwithstanding these advantages, industrial scaling is still difficult since stable electrolyzers, effective electrocatalysts, and economical system designs are required. Electrochemical CO2 recycling is now closer to commercial feasibility thanks to recent advancements in catalyst engineering, electrode architecture, and process optimization that have increased conversion efficiency and product selectivity. The potential of electrochemical CO2 recycling as a crucial technology for accomplishing carbon neutrality and circular economy goals in the chemical sector is highlighted in CO2 reduction analysis.
