Development of Novel Photocatalysts for Solar Energy Conversion

Abstract

The growing demand for sustainable energy has intensified research into solar energy conversion, particularly through the use of photocatalysts. This study explores the development of novel photocatalysts aimed at improving the efficiency of solar energy conversion. We synthesized a series of advanced photocatalytic materials, including metal oxides, sulfides, and hybrid composites, tailored to optimize light absorption, charge separation, and surface reactivity. These materials were systematically characterized using advanced techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), and UV-Vis spectroscopy to elucidate their structural and optical properties. The photocatalytic performance of the developed materials was evaluated under simulated sunlight, revealing significant improvements in hydrogen production, CO2 reduction, and organic pollutant degradation compared to conventional catalysts. The study also investigates the underlying mechanisms of photocatalytic activity, highlighting the role of surface modification and defect engineering in enhancing photocatalyst performance. The findings offer valuable insights into the design of efficient photocatalysts for solar energy applications, paving the way for the development of sustainable energy technologies.
