Special Issue Information

Dear Colleagues,

The increasing concentration of atmospheric CO2 has become one of the most critical challenges facing humanity, driving an urgent need to mitigate climate change and driving extensive research into innovative strategies for CO2 capture, conversion, and utilization. Transforming CO2 into valuable chemicals, fuels, and materials not only reduces greenhouse gas emissions but also contributes to a sustainable circular carbon economy. This Special Issue aims to highlight recent advances in catalytic technologies that enable efficient and selective CO2 valorization and utilization. Topics of interest include, but are not limited to, thermocatalytic, photocatalytic, electrocatalytic, and plasma-assisted CO2 conversion, as well as novel catalyst design, reaction engineering, and mechanistic studies.

We welcome contributions exploring CO2 hydrogenation, dry reforming, electrochemical reduction, and emerging hybrid processes. By showcasing cutting-edge research, this Special Issue seeks to foster interdisciplinary collaboration and accelerate the development of scalable and economically viable CO2 utilization technologies for a greener future.

If you would like to submit papers for publication in this Special Issue or have any questions, please contact the in-house Editor, Mr. Ives Liu (ives.liu@mdpi.com).

With the increase of CO2 emissions caused by human activities, the development of efficient CO2 reduction technology is crucial to help address the energy crisis and mitigate climate change. In this study, a series of Cu3P/SnS2 composites with varying Cu/Sn molar ratios were synthesized using a hydrothermal method to improve the activity and selectivity of the electrocatalytic reduction of CO2 (CO2RR). The successful synthesis and structural advantages of the composite were verified via XRD, XPS, SEM, TEM, and BET. Cu3P/SnS2-3 (Cu/Sn = 2:1) had the largest specific surface area (78.01 m2 g−1) and abundant active sites. The electrochemical performance test showed that in 0.1 M KHCO3 electrolyte saturated with CO2, the Faraday efficiency of Cu3P/SnS2-3 to CO reached 87% at −1.0 V potential, which was 29 times and 1.78 times higher than that of Cu3P (3%) and SnS2 (48.88%). In addition, the catalyst maintained a CO Faraday efficiency of more than 75% in a 5 h stability test. The mechanism study shows that the low Tafel slope, low charge transfer resistance, and high electrochemically active area of the composite significantly promote the CO2RR kinetics. Full article
