At the same time it is shown that monoclinic modification of molybdenum oxide is highly active in the oxidation of ethanol and acetaldehyde can be obtained with high selectivity. The presence of two phase systems: orthorombic and monoclinic oxide structures causes the lower catalytic activity and the simultaneous formation of acetaldehyde and ethylene. Sidvilit has high selectivity to ethylene, although its activity is lower than in the previous two cases It is found that vanadium oxide sample activated in air is highly active in the liquid phase neutralization process of benzene and toluene impurities in water. Simultaneously, we have shown that mechanically activated vanadium oxide is more active during benzene oxidation than the industrial catalyst SX-2305.It is established that complex oxide vanadium-molybdenum catalyst synthesized from mechanoactivated mixture of oxides has higher selectivity to propene at oxidative dehydrogenation of propane than traditional catalyst, and therefore it forms a smaller amount of carbon oxides. It is shown that the use of vanadium oxide at mechanoactivated synthesis of VPO catalyst can solve three environmental problems: i) synthesis of catalyst reduces the number of organic solvent, ii) restorer can be excluded from the catalyst synthesis, iii) high activity and selectivity of the synthesized catalyst reduces CO2 emissions. It is established that the copper-cerium oxide catalyst synthesized by mechanochemical way is an active catalyst for neutralization of harmful emissions of CO and benzene in the air. At the same time, this is an effective catalyst in the reaction of hydrogen purification from carbon monoxide impurities. It is shown that by mechanical processing of the mixture of molybdenum, vanadium and zirconium oxides in water can be synthesized compound H9, 57Zr3V3O3, 1 which is accumulator of hydrogen.
