Abstract
Abstract In view of global energy transition and environmental issues, electrochemical conversion of carbon dioxide (CO 2 ) to high value‐added chemicals by using clean renewable electricity, as an advanced carbon capture, utilization and storage (CCUS) technology, demonstrates a promising approach to reach the carbon neutrality with additional economic benefits as well. Over the past decade, various new valid catalysts in electrochemical CO 2 reduction (ECO2R) have been designed and intensively investigated. Unfortunately, constructing appropriate ECO2R electrolyzer with high conversion rate and long‐term stability to unleash the full potential benefits of electrocatalysts remains a recognized challenge, especially as it has not yet attracted attention. This review summarizes the progress of ECO2R reactor and their corresponding structure characteristics/ electrochemical performance. Besides, the current challenges and bottlenecks of CO2RR reactor are discussed. We aim to introduce the advances in ECO2R electrolyzer in detail to offer enlightenment for large‐scale industrial application of ECO2R. image
