环己烷在可见光下在含有过氧化氢的二氧化钛悬浮液中被氧化。环己醇和环己酮被检测为产物。在相似的实验条件下，壬醛被氧化为壬酸。金红石颗粒的氧化反应速率比金红石颗粒快。当过氧化氢被添加到这些颗粒的悬浮液中时，金红石和金红石颗粒由于在它们的表面上形成过氧化物络合物而变成黄色。金红石和金红石颗粒的反应速率之间的差异表明，在这些颗粒上形成的过氧化物络合物的性质是不同的。用紫外-可见光谱研究了配合物的性质。
Cyclohexane was oxidized under visible light in a titanium dioxide suspension containing hydrogen peroxide. Cyclohexanol and cyclohexanone were detected as products. Under similar experimental conditions, nonyl aldehyde was oxidized to nonylic acid. The reaction rate for the oxidation on rutile particles was faster than that on anatase particles. When hydrogen peroxide was added to suspensions of these particles, both rutile and anatase particles became yellow-colored due to the formation of peroxide complexes on their surfaces. The difference between the reaction rates for rutile and anatase particles suggests that the properties of the peroxide complexes formed on these particles are different. The properties of these complexes were studied by UV–vis spectroscopy.
