三维网状石墨烯修饰二氧化钛光催化剂的制备及性能研究
Preparation and application of TiO 2 composite photocatalyst modified by three-dimensional network graphene
摘要
Abstract
With the gradually increased environmental protection standard, the TiO 2 based photocalalyst becomes a hot issue. The TiO2 composite photocatalyst modified by graphene has attracted more and more attention due to the large BET area and excellent electron transport ability of graphene, which endows the graphene not only act-ing as carrier for TiO2 nanoparticles, but also rapid electron transport network for the resulting composites. In this study, three-dimensional network graphene prepared by chemical vapor deposition approach was adopted to pre-pare composite photocatalyst with TiO2 via hydrothermal progress. The BET area of the fabricated photocatalyst is as high as 390 m2·g-1, indicating outstanding absorbility for the pollution molecules. The degradation rate con-stant of methyl orange reaches 8.1×10-2 min-1 and 2.8×10-2 min-1 under UV-light and visible-light irradiation, re-spectively. The rate constant under UV-light irradiation is 200% higher than that of using pure TiO 2. Moreover, the photocatalyst displays favorable stability after 10 cycle use, manifesting promising application prospect.关键词
