Provided are titanium oxide fine particles capable of enhancing the photocatalytic activity of a photocatalyst when mixed with such photocatalyst. There are provided titanium oxide fine particles with at least an iron component and a silicon component solid-dissolved therein, in which the iron and silicon components are each contained in an amount of 1 to 1,000 in terms of a molar ratio to titanium (Ti/Fe or Ti/Si); and a titanium oxide fine particle dispersion liquid in which these titanium oxide fine particles are dispersed in an aqueous dispersion medium.

A catalyst for a dehydrogenation reaction includes a carrier including Al.sub.2O.sub.3 having a theta (θ) phase, an active metal supported on the carrier and including a noble metal, and an auxiliary metal supported on the carrier and different from the active metal.

In a process for the synthesis of a nitrile by endothermic catalyzed reaction of ammonia with a hydrocarbon using heating obtained by passing an alternating current through a metallic coil, the endothermic reaction between ammonia and the hydrocarbon takes place in a reactor with direct inductive heating in the reaction zone. The heating is extremely fast, which makes the reaction practically instantaneous.

A method of synthesizing a doped carbonaceous material includes mixing a carbon precursor material with at least one dopant to form a homogeneous/heterogeneous mixture; and subjecting the mixture to pyrolysis in an inert atmosphere to obtain the doped carbonaceous material. A method of purifying water includes providing an amount of the doped carbonaceous material in the water as a photocatalyst; and illuminating the water containing the doped carbonaceous material with visible light such that under visible light illumination, the doped carbonaceous material generates excitons (electron-hole pairs) and has high electron affinity, which react with oxygen and water adsorbed on its surface forming reactive oxygen species (ROS), such as hydroxyl radicals and superoxide radicals, singlet oxygen, hydrogen peroxide, that, in turn, decompose pollutants and micropollutants.
