“…Several studies for the continuous electroreduction of CO 2 to HCOO – or HCOOH analyzed in this work have reported the problem of detrimental carbonate salt formation after several hours of operation (e.g., refs , , , , , ). A few works have reported strategies for tackling this problem, essentially based on periodically refreshing the electrolytes (e.g., refs , ) or increasing water availability .…”

The study of the electrochemical CO 2 reduction to obtain formate (HCOO − ) or formic acid (HCOOH) is receiving much attention as a promising technology. Since continuous−mode operation has become necessary for practical implementation of electrochemical CO 2 reduction, recent years have seen a rapid increase in the number of research approaches focusing on this aspect. This Focus Review provides a unified discussion of the available studies on the continuous electroreduction of CO 2 to HCOO − /HCOOH, considering the different important features of process design. Moreover, this paper quantitatively assesses the performance of different studies that involve continuous electrochemical reactors for converting CO 2 to HCOOH/HCOO − , comparing relevant typically used figures of merit, including energy consumption. Although some relevant trade-offs have already been achieved, the simultaneous optimization of all the figures of merit remains a challenge. Finally, concluding remarks highlight the detected trends and discuss relevant aspects that will have to be tackled by future studies in this field.

“…Consequently, exploring ways to convert CO 2 to fuels or other value-added chemicals is critical to mitigating the above problems. Electrochemical CO 2 RR has been regarded as one of the most attractive strategies thanks to its multiple advantages such as ease of operation, mild operating conditions, and tunable products [171][172][173][174]. So far, the development of efficient and stable catalysts remains at the heart of current research.…”

Non-precious metal single-atom catalysts (NPM-SACs) with unique electronic structures and coordination environments have gained much attention in electrocatalysis owing to their low cost, high atomic utilization, and high performance. NPM-SACs on carbon support (NPM-SACs/CS) are promising because of the carbon substrate with a large surface area, excellent electrical conductivity, and high chemical stability. This review provides an overview of recent developments in NPM-SACs/CS for the electrocatalytic field. First, the state-of-the-art synthesis methods and advanced characterization techniques of NPM-SACs/CS are discussed in detail. Then, the structural adjustment strategy of NPM-SACs/CS for optimizing electrocatalytic performance is introduced concisely. Furthermore, we provide a comprehensive summary of recent advances in developing NPM-SACs/CS for important electrochemical reactions, including carbon dioxide reduction reaction, hydrogen evolution reaction, oxygen evolution reaction, oxygen reduction reaction, and nitrogen reduction reaction. In the end, the existing challenges and future opportunities of NPM-SACs/CS in the electrocatalytic field are highlighted.

Electrochemical carbon dioxide (CO2) reduction (ECR) has become more attractive to realize CO2 convert to high value products with renewable electricity. In this review, recent progress in the synthesis and electrochemical application of chalcogenide-derived Cu (including OD-Cu, SD-Cu and SeD-Cu) materials for CO2 electroreduction reaction have been summarized. The kind of ECR products is highly related with the CO2 adsorption pattern and reduction process on catalyst surface. In addition, the structure-activity relationship between crystal structure/morphology/composition of chalcogenide-derived Cu and their ECR activity/selectivity/products have also been discussed. Finally, some prospects on the challenge and future research trends in rational design of high efficient OD-Cu, SD-Cu and SeD-Cu electrodes are provided.
