S-scheme 2D/2D B-doped N-deficient g-C3N4/ZnIn2S4 heterojunction for efficient H2 production intergrated with tertracycline degradation under visible-light illumination
A novel S-scheme 2D/2D boron-doped nitrogen-deficient g-C3N4/ZnIn2S4 (BDCNN/ZnIn2S4) heterojunction was successfully fabricated via the in-situ assembly of ZnIn2S4 onto BDCNN in an oil bath. To assess the quality and characteristics of the synthesized photocatalysts, a comprehensive range of characterizations were conducted. The innovative S-scheme 2D/2D BDCNN/ZnIn2S4 heterojunction, equipped with a deliberately established inter-built electric field, facilitates rapid electron transfer and enhanced separation efficiency of photo-induced carriers. Consequently, this heterojunction demonstrates remarkable enhancements in both H2 production and TC degradation under visible-light illumination (λ > 420 nm). The optimized BDCNN/ZnIn2S4 heterojunction exhibited impressive photocatalytic performance, achieving a promising H2 evolution rate of 2378.8 μmolg−1h−1 and a high degradation efficiency exceeding 90 % (k = 0.021 min−1) for TC. This noteworthy improvement in photocatalytic performance is primarily attributed to the synergistic effects of boron-doping and nitrogen-defects within BDCNN, coupled with the unique S-scheme photocatalytic mechanism inherent to the BDCNN/ZnIn2S4 heterojunction. Overall, this study introduces a groundbreaking approach for constructing 2D/2D g-C3N4-based heterojunctions that exhibit exceptional visible-light photocatalytic capabilities, thereby offering significant potential for various photocatalytic applications.
期刊介绍:
The Process Safety and Environmental Protection (PSEP) journal is a leading international publication that focuses on the publication of high-quality, original research papers in the field of engineering, specifically those related to the safety of industrial processes and environmental protection. The journal encourages submissions that present new developments in safety and environmental aspects, particularly those that show how research findings can be applied in process engineering design and practice.
PSEP is particularly interested in research that brings fresh perspectives to established engineering principles, identifies unsolved problems, or suggests directions for future research. The journal also values contributions that push the boundaries of traditional engineering and welcomes multidisciplinary papers.
PSEP's articles are abstracted and indexed by a range of databases and services, which helps to ensure that the journal's research is accessible and recognized in the academic and professional communities. These databases include ANTE, Chemical Abstracts, Chemical Hazards in Industry, Current Contents, Elsevier Engineering Information database, Pascal Francis, Web of Science, Scopus, Engineering Information Database EnCompass LIT (Elsevier), and INSPEC. This wide coverage facilitates the dissemination of the journal's content to a global audience interested in process safety and environmental engineering.
