Understanding Photocatalytic Decontamination with Chemically Bonded Photocatalysts
Photocatalytic decontamination is a process that involves using specific materials to cleanse pollutants from the environment by harnessing the power of light. One key aspect of this process is the development of high-performance photocatalysts that can efficiently separate photo-carriers and possess strong redox potentials to enhance the removal of pollutants. In a recent study published in Advanced Powder Materials, researchers from Zhejiang Ocean University and the University of Missouri have made significant progress in this area by exploring the use of a chemically bonded photocatalyst with rich oxygen vacancies for improved photocatalytic decontamination.
Challenges in Industrial Application of Photocatalysis
The industrial application of photocatalysis technology for environmental remediation faces several challenges, one of which is the design of effective photocatalysts. These catalysts must have the ability to separate photo-carriers efficiently and exhibit strong redox potentials to enhance the process of pollutant removal. Without these characteristics, the practical application of photocatalysis technology is hindered, limiting its potential impact on environmental protection.
Modulation of Interfacial Chemical Bonds for Enhanced Performance
In the study, the researchers focused on modulating the interfacial chemical bond of Mn0.5Cd0.5S/BiOBr with rich oxygen vacancies to improve the photocatalytic performance. By creating a chemically bonded S-scheme photosystem of Mn0.5Cd0.5S/BiOBr, the team aimed to enhance the decontamination efficiency of antibiotics and Cr(VI). This innovative approach involved pinning Mn0.5Cd0.5S nanoparticles on BiOBr microflowers to facilitate effective pollutant removal. The presence of interfacial bond and oxygen defects played a crucial role in boosting the photocatalytic performance of the catalyst.

Powder coating
Powder coating is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint, which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light. The powder may be a thermoplastic or a thermoset...
