The application discloses a kind of preparation and application of g-C3N4 / VPO photothermal catalytic material, its characteristics are that g-C3N4 nanosheet is assembled with VPO nanosheet using electrostatic assembly strategy, and photothermal catalytic material of general formula g-C3N4 / VPO is obtained.Under photothermal condition, g-C3N4 / VPO is used as photothermal catalyst, and high-efficiency selective oxidation of n-butane is carried out to prepare maleic anhydride at low temperature.Compared with prior art, the application has the advantages of low reaction temperature, high selectivity, mild preparation conditions, large-scale preparation, green reaction, and wide application prospect.

The application provides a preparation method and application of a Pd-Ni composite metal oxide methane dry reforming catalyst. The application uses a palladium-nickel-based composite metal oxide catalyst with distributed active metals (Ni, Mg, Pd). The application applies the catalyst to a methane dry reforming reaction to prepare synthesis gas. The preparation method is simple. The proportion of each metal in the catalyst is adjustable and controllable, and the active metal nickel is uniformly distributed. Through relevant data processing and catalyst evaluation, it is confirmed that the catalyst has high catalytic activity, and has remarkable anti-coking and anti-sintering abilities. After 600 hours of stability test, the methane and carbon dioxide conversion rates are high and stable, and the H2 / CO ratio of the obtained synthesis gas is close to 1.
