Abstract
A novel BiOCl/Co catalyst was constructed by in situ doping of metal Co nanoparticles on n-type BiOCl nanosheets. The percentage of metal Co incorporated in the photocatalysts was adjusted to improve the degradation performance of the new catalysts against pollutants. The optimized BiOCl/Co achieved up to 95.5% photocatalytic degradation efficiency of rhodamine B (RhB). This might be attributed to the enhanced visible light absorption ability of BiOCl/Co by plasmon resonance (SPR) as well as the effective interfacial separation and transport of carriers in BiOCl/Co. BiOCl/Co showed excellent mineralization capacity and reuse performance in the degradation of RhB. Furthermore, it was shown that photogenerated h+, ⋅OH and ⋅O2− were the major reactive substances for dye degradation. The photodegradation mechanism of RhB by BiOCl/Co was elucidated in this paper.
期刊介绍：
The Journal of Materials Science: Materials in Electronics is an established refereed companion to the Journal of Materials Science. It publishes papers on materials and their applications in modern electronics, covering the ground between fundamental science, such as semiconductor physics, and work concerned specifically with applications. It explores the growth and preparation of new materials, as well as their processing, fabrication, bonding and encapsulation, together with the reliability, failure analysis, quality assurance and characterization related to the whole range of applications in electronics. The Journal presents papers in newly developing fields such as low dimensional structures and devices, optoelectronics including III-V compounds, glasses and linear/non-linear crystal materials and lasers, high Tc superconductors, conducting polymers, thick film materials and new contact technologies, as well as the established electronics device and circuit materials.
