研究目的
Investigating the effects of reaction conditions on the formation features, particle size, phase composition, morphology, and photocatalytic properties of products synthesized from potassium titanium oxalate.
研究成果
TiO2 powders with different morphology and phase structure were prepared from potassium titanium oxalate and H2O2 in acid medium. A new material C2O7Ti2·3H2O was obtained without H2O2, showing good photocatalytic activity in the degradation of MO, with ?O2? playing a major role in the degradation process.
研究不足
The study focuses on the photocatalytic degradation of methyl orange under UV light, and the stability and photocatalytic activity under visible light or other conditions were not investigated.
1：Experimental Design and Method Selection:
Different products were synthesized using potassium titanium oxalate as the precursor under varying reaction conditions. The influences of reaction system conditions on the products were investigated.
2：Sample Selection and Data Sources:
Potassium titanium oxalate (C4K2O9Ti·2H2O, >90%) was used as the precursor.
3：List of Experimental Equipment and Materials:
Powder X-Ray diffractometer (Rigaku, D/MAX -Ultima IV), scanning electron microscope (JEOL JSM-7800F, Japan), UV-vis spectrophotometer (UV-7230G, China), UV-vis spectrophotometer (Varian Cary 5000, America).
4：Experimental Procedures and Operational Workflow:
The synthesis involved hydrothermal treatment of the reaction system including HCl and H2O2 solution. The photocatalytic activity was evaluated by the degradation of methyl orange under UV light.
5：Data Analysis Methods:
The photocatalytic activity was characterized by degradation rate determined using UV-vis absorption spectra.
