The electrochemical CO2 reduction reaction (eCO2RR) is a promising approach for converting to useful chemicals and, hence, achieving carbon neutrality. Though high selectivity and activity of products have been achieved recently, all are reported in neutral or alkaline electrolytes. Although these electrolyte media give activity, they face the major challenge low utilization because carbonate formation, which lowers overall efficiency process. Conducting eCO2RR acidic can help overcome issue formation hence increase efficiency. However, there many challenges associated with eCO2RR. Two concerns highly competitive hydrogen evolution salt precipitation issues. This Perspective focuses on fundamentals eCO2RR, recent catalyst development strategies, relevant problems that need be addressed future. In end, we provide future outlook will an idea about focus field
