中文摘要：

采用酸性碘化钾（KI）溶液还原由真空抽滤得到氧化石墨烯薄膜制备得到了完整性良好的石墨烯薄膜。研究表明，体系中盐酸浓度和反应时间影响KI还原氧化石墨烯薄膜的效果。当采用盐酸浓度为ImolL-1。的50％KI溶液还原氧化石墨烯膜30min时，制得的石墨烯薄膜具有良好的柔韧性和较高的完整性。

英文摘要：

Hydrothermal method for the preparation of titania nanomaterial has received wide attentions due to its simple operation, low cost and environment friendly. This paper provides a review of the recent progress in different morphology of titania nanomaterial prepared by hydrothermal method. The properties and disadvantages of each titania nanomaterial are also summarized and analyzed. Prospects for future development in hydrothermal preparation of titania nanomaterial are proposed.
