Embodiment 1
[0042] The method provided by the invention is used to degrade the wastewater containing nitrobenzene.
[0043] Preparation of photocatalyst material: The titanium sheet was ultrasonically cleaned in acetone, absolute ethanol and distilled water for 15 min in sequence, and dried in nitrogen. Two-electrode system is adopted: the power supply adopts a DC stabilized power supply, and the titanium sheet is used as the anode to connect to the positive electrode of the DC power supply, and the platinum sheet (2cm×2cm) is connected to the negative electrode of the power supply as the counter electrode. 4 F+(CH 2 Oh) 2 +2vol%H 2 In the electrolyte solution composed of a mixed solution of O, the electrolysis was carried out at a constant voltage of 50V at room temperature, and the electrolysis time was 30min. After the reaction, the titanium sheet was rinsed with distilled water, placed in a muffle furnace in an air atmosphere, and the temperature was raised from room temperature to...
