Influence of Dopants on the Photocatalytic Activity of ZnO

Zinc oxide zincite (ZnO) exhibits remarkable light-driven properties due to its wide band gap and high surface area, making it a promising material for environmental remediation and energy applications. However, the effectiveness of ZnO in photocatalysis can be substantially enhanced by introducing dopants into its lattice structure. Dopants modify the electronic structure of ZnO, leading to improved charge transport, increased utilization of light, and ultimately, a higher yield of photocatalytic products.

Various types of dopants, such as transition metals, have been investigated to improve the activity of ZnO photocatalysts. For instance, nitrogen doping has been shown to create oxygen vacancies, which accelerate electron flow. Similarly, transition metal oxide dopants can modify the band gap of ZnO, broadening its range and improving its sensitivity to light.

Thermal Degradation Kinetics of Polypropylene Composites Composites

The thermal degradation kinetics of polypropylene composites have been the focus of extensive research due to their significant impact on the material's performance and lifespan. The study of thermal degradation involves analyzing the rate at which a material decomposes upon exposure to increasing temperatures.
