Abstract: A non-human organism for upgrading intermediate oxidation products formed by catalytic degradation of alkanes or polystyrenes is provided. The non-human organism is genetically modified to convert the intermediate oxidation products to secondary metabolites, and in particular to include a positive feedback loop construction in the promotor system. A method includes steps of catalytically degrading alkanes or polystyrene in an oxidizing environment to form intermediate products with one or more catalysts and contacting the intermediate products with the non-human organism such that intermediate oxidation products are converted to secondary metabolites.

Abstract: Disclosed are a grain boundary and surface-doped rare earth manganese-zirconium composite compound as well as a preparation method and use thereof. A rare earth manganese oxide with a special structure is formed at grain boundary and surface of a rare earth zirconium-based oxide by a grain boundary doping method so as to increase oxygen defects at the grain boundary and the surface, thereby increasing the amount of active oxygen, improving the catalytic activity of the rare earth manganese-zirconium composite compound, inhibiting high-temperature sintering of the rare earth manganese-zirconium composite compound, and improving the NO catalytic oxidation capability. When the rare earth manganese-zirconium composite compound is applied to a catalyst, the consumption of noble metal can be greatly reduced.
