【摘要】：光催化技术是解决能源短缺和环境污染问题的最有效解决途径之一,近期引起了世界各国科学家们的广泛关注。然而,目前光催化材料较低的转化效率,严重制约了光催化技术的进一步发展和实际应用。因此,设计和制备新型高效光催化材料具有重要意义。我们基于材料晶体结构设计,并结合材料微结构调控和制备技术,从拓展光催化材料的光吸收范围和提高光生载流子分离效率两个制约光催化效率的最主要问题入手,提出了一些新型高效光催化材料的设计理论和制备方法。主要围绕表面等离子体光催化材料、红外光催化材料、极性光催化材料等几种新型光催化材料,对材料设计理论、制备方法、结构与性能之间的关系及光催化微观机理几个方面进行了详细讨论。
[Abstract]:Photocatalytic technology is one of the most effective ways to solve the problem of energy shortage and environmental pollution, which has attracted the attention of scientists all over the world recently. However, the low conversion efficiency of photocatalytic materials seriously restricts the further development and practical application of photocatalytic technology. Therefore, it is of great significance to design and prepare new high efficient photocatalytic materials. Based on the crystal structure design of the materials, and combining with the control and preparation techniques of the microstructure of the materials, we begin with the two most important problems which restrict the photocatalytic efficiency, namely, expanding the range of photoabsorption of photocatalytic materials and improving the efficiency of photocatalytic carrier separation. The design theory and preparation method of some new high efficient photocatalytic materials are presented. Focusing on several new photocatalytic materials, such as surface plasma photocatalytic materials, infrared photocatalytic materials, polar photocatalytic materials, etc., the design theory and preparation methods of the materials are discussed. The relationship between structure and performance and the microscopic mechanism of photocatalysis were discussed in detail.
