Abstract

SnO₂/ZnS nanocomposites were successfully synthesized using a modified hydrothermal route. The synthesis involved separate co-precipitation of SnO₂ and ZnS, followed by ultrasonic stirring and hydrothermal treatment. The resulting nanocomposites exhibited controlled size and composition. By adjusting synthesis parameters such as the molar ratio of Sn to Zn, reaction temperature, and reaction time, the morphology and properties of the nanocomposites could be finely tuned. The synthesized SnO₂/ZnS nanocomposites demonstrated remarkable improvements in photocatalytic performance compared to pure SnO₂ or ZnS nanoparticles. This enhancement was attributed to the nanocomposites' enhanced charge separation, increased surface area, and improved light absorption capabilities. As a result, the SnO₂/ZnS nanocomposites hold great promise for a wide range of applications, including environmental remediation, water splitting, and solar energy conversion.

提高通过双步沉淀和超声水热法合成的 SnO2/ZnS 纳米复合材料的光催化性能

采用改良水热法成功合成了 SnO2/ZnS 纳米复合材料。合成过程包括分别共沉淀二氧化锡和锌锡，然后进行超声波搅拌和水热处理。所得纳米复合材料的尺寸和成分均可控。通过调整合成参数，如 Sn 与 Zn 的摩尔比、反应温度和反应时间，可以对纳米复合材料的形态和性质进行微调。与纯 SnO2 或 ZnS 纳米粒子相比，合成的 SnO2/ZnS 纳米复合材料的光催化性能有了显著提高。这种改进归因于纳米复合材料增强了电荷分离、增大了比表面积并提高了光吸收能力。因此，SnO2/ZnS 纳米复合材料在环境修复、水分离和太阳能转换等广泛应用中大有可为。

期刊介绍： Current Applied Physics (Curr. Appl. Phys.) is a monthly published international journal covering all the fields of applied science investigating the physics of the advanced materials for future applications. Other areas covered: Experimental and theoretical aspects of advanced materials and devices dealing with synthesis or structural chemistry, physical and electronic properties, photonics, engineering applications, and uniquely pertinent measurement or analytical techniques. Current Applied Physics, published since 2001, covers physics, chemistry and materials science, including bio-materials, with their engineering aspects. It is a truly interdisciplinary journal opening a forum for scientists of all related fields, a unique point of the journal discriminating it from other worldwide and/or Pacific Rim applied physics journals. Regular research papers, letters and review articles with contents meeting the scope of the journal will be considered for publication after peer review. The Journal is owned by the Korean Physical Society.
