Provided in this disclosure are oxidative dehydrogenation catalysts that include a mixed metal oxide having the empirical formula:
Mo.sub.1.0V.sub.0.12-0.49Te.sub.0.05-0.17Nb.sub.0.10-0.20O.sub.d
wherein d is a number to satisfy the valence of the oxide. The oxidative dehydrogenation catalyst is characterized by having XRD diffraction peaks (2θ degrees) at 22±0.2, 27±0.2, 28.0±0.2, and 28.3±0.1. The disclosure also provides methods of making the catalysts that include wet ball milling.

The invention is in the field of catalysis. In particular, the invention is directed to a catalytic reactor body, a method for the production of a catalytic reactor body and a use of a catalytic reactor body.

The invention provides a catalytic reactor body, comprising a circumferential reactor wall extending in a main fluid flow direction of the reactor body between a reactor inlet and a reactor outlet thereby forming a channel for conducting a fluid; and a reactor bed arranged in the channel and being integrally formed with the circumferential reactor wall, wherein the reactor bed forms a plurality of sub-channels for guiding the fluid from the reactor inlet to the reactor outlet, each sub-channel defining a predetermined fluid path between the reactor inlet and the reactor outlet and being configured for directing the fluid in a direction at least partly transverse to the main flow direction.

A preparation method of photo catalyst by transition metal halide molten salt and use thereof, wherein low-valence titanium complexes stable in air and water are used as a Ti source, transition metal halide is used as molten salt, mixing the Ti source and the molten salt as per a certain mole ratio and grinding, heating at air atmosphere until no lower than a fusion point of the molten salt, keeping the molten salt in a state of melting, maintaining the temperature, washing with water, and reduced TiO.sub.2−x rich in Ti.sup.3+ and Ov is obtained in one-step melting reaction. Deficiencies that multiple steps are involved for preparing conventional defect titanium dioxide or use of inflammable and explosive reducing gases or other dangerous reducing agents or oxidizing agents have been addressed; and the defect that the Ti source is liable to be dissolved in organic and other solvents is fully avoided.
