吸附是去除环境污染物最为有效的技术之一，新型发展起来的碳气凝胶材料除了拥有高的比表面积和化学稳定性以及较好吸附能力等优点外，还具有更为优异的光电性质, 这使得其可以更为优异的载体材料和电子传输体。本项目拟采用生物模板的方法，选取含碳量较大的植物为模板，制备出具有生物模板多级结构的碳气凝胶材料。然后，通过对碳气凝胶材料进行表面修饰或是加入交联剂等方法，与半导体光催化材料进行复合。通过一系列的表征手段，探索生物模板的应用和制备条件对于材料性能的影响。考察吸附-光催化的耦合降解环境污染物的性能，并研究其作用机制。为开发出具有高效、易得，可大规模推广的新型光催化材料提供理论依据和实验方法。

Adsorption is one of the most effective technologies to remove environmental pollutants. Carbon aerogel in addition to having huge surface area, high chemical stability and large adsorption capacity, there are excellent optical and electrical properties. These make it as an excellent carrier material and electronic transmission body. This proposal will study on bio-templated carbon aerogel-semiconductor composites for adsorption-photocatalytic degradation of pollutants. Carbon aerogel with hierarchical morphologies of biological templates will be prepared using the carbon containing large plants as bi-templates. Then composites with semiconductor photocatalytic material and carbon aerogel will be synthesized via modifying surface of carbon aerogel material and adding crosslinking agent. Characterizations of the composition, structure, surface state and energy band structure of the catalysts, as well as their activities for the adsorption/photocatalysis to remove environmental pollutants will be studied. The transient, in situ research means and results of electrochemical tests will be combined to unravel the interaction relationships between the physical properties (including composition, structure and surface state) and photocatalytic activity. The research could provide some theoretical basis and experimental methods of designing for highly efficient, easy obtained, and large-scale promotion photocatalytic materials.
