As global CO2 emissions continue to rise, addressing their environmental impact is critical in combating climate change. Photocatalytic reduction, which mimics natural photosynthesis by converting into valuable fuels and chemicals using solar energy, represents a promising approach for both reducing storing energy sustainably. However, the development of efficient photocatalysts, particularly those capable absorbing visible light, remains challenge. Graphitic carbon nitride (g-C3N4) has gained attention its light absorption chemical stability, though performance hindered rapid electron–hole recombination. Similarly, bismuth tungstate (Bi2WO6) visible-light-active photocatalyst with properties, but also suffers from limited efficiency due charge To overcome these limitations, this study focuses on design synthesis g-C3N4/Bi2WO6 composite photocatalyst, leveraging complementary properties materials. The benefits enhanced separation through formation heterojunction, recombination rates improving overall photocatalytic performance. optimized exhibited significant improvements production CH4 CO, achieving 18.90 17.78 μmol/g/h, respectively, are 2.6 times 1.6 higher than pure Bi2WO6. explores how optimizing interface, increasing surface area, adjusting material ratios can further enhance reduction. Our findings demonstrate potential solar-driven conversion, offering new insights paving way future advancements mitigation technologies.

Evolution of the Radiation Shielding, Optical, and Luminescence Properties of PbO2-SiO2 Glass Systems and the Influence of Rare Earth Elements (Eu, Ce, Yb)

Applied Sciences, Год журнала: 2025, Номер 15(2), С. 864 - 864

Опубликована: Янв. 16, 2025

This study explores the physical, radiation shielding, optical, and photoluminescent properties of PbO2-SiO2-based glass systems. Traditional shielding materials, like lead concrete, face challenges due to toxicity weight. Glass materials provide an alternative, offering transparency efficiency. Four systems were analyzed: PbO2-SiO2 (PS), PbO2-SiO2-CeO2 (PSC), PbO2-SiO2-Eu2O3 (PSE), PbO2-SiO2-Yb2O3 (PSY). The results show that rare earth elements densify network, thereby enhancing attenuation properties, quantified through parameters linear coefficient (μ), half-value layer (HVL), mean free path (MFP). PSY system exhibited best demonstrating its potential for use in gamma ray shielding. Samples PS0–PS3 revealed semiconducting behavior may be considered a promising host matrix solar cells w-LED applications.
