| titleOfInvention | A method of obtaining a photocatalyst based on alkaline earth metal bismuthate and a method for purifying water from organic pollutants by a photocatalyst |
| abstract | 1. A method of producing a bismuthate alkaline earth metal photocatalyst based on dissolving bismuth nitrate and alkaline earth metal nitrate in a solvent, followed by annealing the precursor to form an amorphous alkaline earth metal bismuth photocatalyst and thermally forming its crystal lattice, characterized in that the quantitative ratio of bismuth nitrate and alkaline earth metal nitrate are selected from the condition of compliance with one of the non-stoichiometric compositions in alkaline earth metal tautate with an alkaline earth metal oxidation degree not equal to two, an aqueous solution of polyhydric alcohol containing at least five carbon atoms is selected as a solvent, it is evaporated before annealing the precursor to form (form) an organic matrix with uniformly distributed bismuth and alkaline earth metal atoms, annealing organic matrix is carried out at a temperature of 550-650 ° C until the formation of nanoparticles of amorphous alkaline earth metal bismuthate non-stoichiometric with stava with a degree of oxidation of the alkaline earth metal is not equal to two, and thermal forming the crystal lattice of the photocatalyst is conducted at a temperature 650-750ºS.2. A method of producing a photocatalyst based on an alkaline earth metal bismuthate according to claim 1, characterized in that the organic matrix is annealed for 3-4 hours. A method for producing a photocatalyst based on an alkaline earth metal bismuthate according to claim 1, characterized in that the thermal formation of the crystal lattice of the photocatalyst is carried out for 8-10 hours.
