Special Issue Information
Dear Colleagues,
The increasing concentration of CO2 in the atmosphere is widely recognized as a primary driver of global warming and environmental degradation. Photocatalytic CO2 reduction has emerged as a promising approach to address this challenge by efficiently harnessing abundant and clean solar energy into valuable chemical energy. Various photocatalysts, including metal chalcogenide (e.g., TiO2, Bi2WO6 and ZnIn2S4), C3N4, metal–organic frameworks (e.g., MIL-125-NH2, MOF-808 and UiO-66) and covalent-organic frameworks (e.g., COF-5, TpBpy and Py-BSZ-COF), have been explored for suitability in photocatalytic CO2 reduction. However, these materials still demonstrate suboptimal photocatalytic efficiency and have yet to reach practical applicability. Furthermore, a variety of products can be produced through photocatalytic CO2 reduction owing to the complex multiple electron and proton transfer processes, which induce depressing product selectivity. Therefore, a key challenge persists in the development of photocatalysts that can achieve both high catalytic activity and selectivity. Overcoming these challenges is essential for the photocatalytic CO2 reduction progression, facilitating the development of more efficient and sustainable photocatalytic systems aimed at mitigating carbon emissions and promoting renewable energy solutions.
The Special Issue titled "Photocatalysts for CO2 Reduction" focuses on the development, characterization, and application of advanced photocatalysts for converting CO2 into valuable chemicals or fuels. This Issue welcomes original research, reviews, and perspectives on innovative materials preparation and catalytic mechanisms to enhance the efficiency of photocatalytic CO2 reduction. The key areas of interest include the design and synthesis of novel photocatalysts, insights into reaction pathways, and strategies to improve the selectivity, stability, and scalability of photocatalytic CO2 reduction processes in order to pave the way for scalable and sustainable solutions to mitigate climate change and promote environmental remediation.
