Abstract
Our research unveils the synthesis of BiVO4-Bi2O3 triangular sheet composites, demonstrating their impact on charge separation ability under visible light irradiation. We found that composites with optimal BiVO4 content exhibit enhanced photocurrent density, reduced interfacial resistance, prolonged carrier life, increased surface active sites, improved charge transfer efficiency, and carrier concentration. The proposed Z-scheme mechanism appears to govern this composite system’s efficient separation of photogenerated carriers. These findings underscore the potential of BiVO4-Bi2O3 triangular sheet composites in adjusting photosensitivity and enhancing the photocatalytic ability of β-Bi2O3 triangular sheets, opening up new avenues for research in the application of the sustainable environment field.
期刊介绍：
In 1985, the Journal of Science was founded as a platform for publishing national and international research papers across various disciplines, including natural sciences, technology, social sciences, and humanities. Over the years, the journal has experienced remarkable growth in terms of quality, size, and scope. Today, it encompasses a diverse range of publications dedicated to academic research.
Considering the rapid expansion of materials science, we are pleased to introduce the Journal of Science: Advanced Materials and Devices. This new addition to our journal series offers researchers an exciting opportunity to publish their work on all aspects of materials science and technology within the esteemed Journal of Science.
With this development, we aim to revolutionize the way research in materials science is expressed and organized, further strengthening our commitment to promoting outstanding research across various scientific and technological fields.
