Abstract

Mixed cobalt and nickel oxides MTiO₃/TiO₂ (M = Co²⁺, Ni²⁺) are synthesized. Organometallic complexes of titanium tetrabutylate Ti(OBu)₄ with 1,2-dihydroxybenzene and nitrate hydrates of corresponding metals (M) synthesized under conditions of the modified sol-gel process are used as precursors. The synthesized samples are characterized by field-emission scanning electron microscopy, energy-dispersive X-ray analysis, diffuse reflectance spectroscopy, dispersive X-ray radiation analysis, X-ray diffraction, and low-temperature nitrogen adsorption. The photocatalytic activity of the samples is tested in the ultraviolet spectral range (200 nm < λ < 400 nm) in the photodegradation of 1,2-dihydroxybenzene (catechol) in aqueous solutions.

混合氧化物MTiO 3 / TiO 2（М= Co，Ni）在水溶液中1,2-二羟基苯光降解反应中的理化特性和催化活性

摘要

合成了钴和镍的混合氧化物MTiO ₃ / TiO ₂（M = Co ₂ ⁺，Ni ²⁺）。四丁酸钛Ti（OBu）_4的有机金属配合物在改性溶胶-凝胶法的条件下合成的具有1，2-二羟基苯和相应金属（M）的硝酸盐水合物的前体被用作前体。合成的样品通过场发射扫描电子显微镜，能量色散X射线分析，漫反射光谱，色散X射线辐射分析，X射线衍射和低温氮吸附进行表征。在水溶液中1,2-二羟基苯（邻苯二酚）的光降解过程中，在紫外光谱范围（200 nm <λ<400 nm）中测试了样品的光催化活性。
