Development of High-Effectiveness Photocatalytic Materials for Water Purification and Environmental Remediation

Abstract

The development of high-efficiency photovoltaic systems is essential to prevent environmental pollution, especially in water and air purification. This study addresses the problem of poor performance of existing photocatalytic materials under visible light, which limits their practical application. The main objective of this research was to design and characterize advanced fluorescent materials, enhance their performance by doping composites, and test their performance on the degradation of various impurities Nitrogen-doped TiO2 obtained 90% degradation of methylene blue in 60 minutes in visible light, while undoped TiO2 degradation was 70%. Similarly, the ZnO-based photocatalysts showed 85% removal of pesticides in sunlight, and the TiO2/graphene composites showed 85% reduction of benzene (VOCs) in 2 hours, which exceeded 60 % decrease by pure TiO2 this result highlights the effectiveness of doping and composite fabrication to enhance the photocatalytic performance. The review also highlights the potential for large-scale environmental applications, and the importance of addressing practical challenges such as photocatalyst recovery and energy stability Future research will focus on strategies a through optimization, exploration of new combinations, and long-term field surveys.
