Special Issue Information

Dear Colleagues,

Solar energy conversion and utilization have undergone great development in the past few years. The study of novel photocatalytic materials and their surfaces has led to many exciting advancements in the field of catalysis. Photocatalysis is an emerging technique for converting solar energy into renewable and storable chemical energy in chemical bonds. Solar-driven hydrogen generation and CO2 reduction is one of the most promising techniques for future energy consumption, and various new methods and sustainable efforts have been developed. Thus far, a great number of homogeneous systems, nano-systems, and polymer systems have been proven effective in photocatalytic reactions due to their unique catalytic properties and the ideal bandgap of the material structure, acting as a milestone for future studies. The effective development of photocatalytic activity is enabled by the tunable electronic structure, ideal bandgap, flexibility for doping and defect formation, and the presence of highly active sites in novel photocatalytic materials. There are many promising materials that will continue to help in addressing the current worldwide energy issue.

This Special Issue aims to summarize the progress and advances in the development of new photocatalysts and photocatalytic systems for hydrogen generation and CO2 reduction. You are invited to submit contributions presenting your recent research articles, reviews, and brief communications revealing new trends in the research on photocatalytic hydrogen generation and CO2 reduction. Hence, immense challenges and opportunities remain in realizing this technology for large-scale practical applications in the decontamination of the environment and the generation of clean energy.

The development of photocatalysts with a wide spectral response and effective carrier separation capability is essential for the green degradation of tetracycline hydrochloride. In this study, a magnetic recyclable Z-scheme ZnO/ZnFe2O4 heterojunction (ZZF) was successfully constructed via the solid phase method, using MIL-88A(Fe)@Zn as the precursor. An appropriate band gap width and Z-scheme charge transfer mechanism provide ZZF with excellent visible light absorption performance, efficient charge separation, and a strong redox ability. Under visible light irradiation, the degradation efficiency of tetracycline hydrochloride for the optimal sample can reach 86.3% within 75 min in deionized water and 92.9% within 60 min in tap water, exhibiting superior stability and reusability after five cycles. Moreover, the catalyst in the water can be conveniently recovered by magnetic force. After visible light irradiation for 70 min, the temperature of the reaction system increased by 21.9 °C. Its degradation constant (35.53 × 10−3 min−1) increased to 5.1 times that at room temperature (6.95 × 10−3 min−1). Using thermal energy enhances the kinetic driving force of the reactants and facilitates carrier migration, meaning that more charge is available for the production of •O2 and •OH. This study provides a potential candidate for the efficient degradation of tetracycline hydrochloride by combining thermal catalysis with a photocatalytic heterojunction. Full article
