| titleOfInvention | Preparation method of carbon-doped bismuth oxide photocatalytic material |
| abstract | The invention discloses a preparation method of a carbon-doped bismuth oxide photocatalytic material, which comprises the steps of putting bismuth nitrate pentahydrate into an aluminum oxide crucible, annealing at 500 ℃ for 6 hours to prepare alpha-Bi 2 O 3 Powder material, and the prepared alpha-Bi 2 O 3 And placing the powder material in an alumina crucible, adding oxalic acid dihydrate powder, uniformly mixing, and annealing at 280 ℃ for 50-200 min to obtain the carbon-doped bismuth oxide photocatalytic material. The preparation method is simple and feasible in preparation process and short in synthesis period, compared with undoped bismuth oxide, the carbon-doped bismuth oxide photocatalytic material has the advantages that the light absorption edge moves towards the long-wave direction, the utilization rate of light waves in the visible light wavelength range of 400-500 nm is high, the photocatalytic performance is obviously improved, and the carbon-doped bismuth oxide photocatalytic material has potential application value in the aspect of photoelectric materials. |
