摘 要由于环境污染和饮用水资源的破坏，使得我国面临着饮用水的短缺和污染，这已然成为了一个全球性的重要问题。对生态环境和人类健康都造成很大的危害和影响。过去几十年间，我国虽然已经着手控制水资源的污染，但是效果不是非常的理想。且我国正处于工业化的快速发展中，水资源污染的发展趋势非常的严峻。
TiO2作为光催化剂对农药、染料、医药、造纸、化工等废水进行处理，都能对污染物有效地进行脱色、降解、去毒、矿化为无机小分子。但是 TiO2作为光催化剂，在实际应用中存在太阳能利用率低、光量子效率低、催化剂回收过程复杂等不足。我们将以 TiO2纳米粉、四氯化钛、环氧丙烷等作为原料，溶胶凝胶法制得二氧化钛-炭气凝胶，制备了催化活性较高的 TiO2/C 杂化气凝胶。我们还将进一步对 TiO2/C杂化气凝胶的性能进行研究。9346

Abstract
Due to environmental pollution and drinking water resources destruction, making China is
facing water shortages and pollution, which has become an important global issue. Ecological
environment and human health have been caused great harm and impact. Over the past few
decades, even though China has started to control water pollution, but the effect is not very
satisfactory. And China is in rapid development of industrialization, the development trend of
water pollution is very serious.
TiO2 as a photocatalyst for pesticides, dyes, pharmaceuticals, paper and chemical wastewater treatment,
can effectively bleaching of pollutants, degradation, detoxification and mineralization of small inorganic
molecules. However, TiO2 as a photocatalyst in the practical application of solar energy utilization is low, a
low quantum efficiency, catalyst recovery process less complicated. We will TiO2 nanopowder, titanium
tetrachloride, and propylene oxide as starting materials, sol-gel derived titania - carbon carbon aerogels,
higher catalytic activity prepared TiO2 / C hybrid aerogels. We will also further TiO2 / C hybrid aerogels
studied the performance.
KeyWords:Titanium dioxide; photocatalysis; carbon airgel; fuel waste; preparation, characterization.
