摘要: This paper presents an experimental approach to study catalytic effects of Fe3+ modified nanometer titanium dioxide (TiO2) loaded on aluminium oxide (Al2O3). Sol-gel method was used prepare TiO2 carrier. Purification tests were conducted in a self-developed instrument Al2O3 with different contents through degradation rate. The modification mechanism studied by scanning electron microscope (SEM). Results showed that loading improved photocatalytic effect Fe3+. best achieved under action 10% composite; the rates 6.9%, 13.8%, 21.4%, and 49.2%, respectively, 0.7%, 3.9%, 1.3%, 15.1% larger than unloaded TiO2. SEM results four catalysts coated form grain surface Al2O3. optimal content at which grains uniformly.
