Embodiment 1

[0018] Weigh 0.4851g of bismuth nitrate, 0.0624g of sodium dihydrogen phosphate, 0.0702g of ammonium metavanadate, and 1g of attapulgite into 10ml of deionized water and stir thoroughly with ultrasonic waves, transfer the obtained dispersion to a microwave hydrothermal reaction kettle, and heat Incubate for 90 minutes, centrifuge, wash with water and absolute ethanol, and dry in an oven at 80°C to obtain BiP 1-x V x o 4 / ATP nanocomposite (x=0.6).

[0019] With reference to the process parameters of Example 1, the undoped bismuth phosphate / attapulgite composite material was prepared, and the X-ray powder diffraction was compared with the sample of the composite material obtained above, specifically as figure 1 As shown: the sample obtained above has a shift of the characteristic peak at 29.04°, indicating that the vanadium doping has entered the phosphorus lattice, and the characteristic peak of the attapulgite also appeared in the XRD of the composite material, indicating t...

Embodiment 2

[0031] Weigh 0.4851g of bismuth nitrate, 0.0936g of sodium dihydrogen phosphate, 0.0486g of ammonium metavanadate, and 1g of attapulgite into 10ml of deionized water in sequence and stir thoroughly with ultrasonic waves. Incubate for 90 minutes, centrifuge, wash with water and absolute ethanol, and dry in an oven at 80°C to obtain BiP 1-x V x o 4 / ATP nanocomposite (x=0.4). Subsequent testing was as in Example 1, and the desulfurization rate obtained was 90%.

Embodiment 3

[0033] Weigh 0.4851g of bismuth nitrate, 0.0780g of sodium dihydrogen phosphate, 0.0585g of ammonium metavanadate, and 1g of attapulgite into 10ml of deionized water in sequence and stir thoroughly with ultrasonic waves. Incubate for 90 minutes, centrifuge, wash with water and absolute ethanol, and dry in an oven at 80°C to obtain BiP 1-x V x o 4 / ATP nanocomposite (x=0.5). Subsequent detection was as in Example 1, and the obtained desulfurization rate was 93.2%.

Description

technical field [0001] The invention belongs to the field of new chemical materials, and in particular relates to a vanadium-doped bismuth phosphate / attapulgite nanocomposite material and a preparation method and application thereof. Background technique [0002] In recent years, many environmental problems including acid rain and smog have become more and more serious, and these problems all come from the sulfur oxides produced by gasoline combustion, which greatly threaten human health. Therefore, it is extremely urgent to develop a green and efficient deep desulfurization technology. [0003] Traditional hydrodesulfurization requires high temperature, pressure and expensive hydrogen, and it is difficult to achieve the effect of deep desulfurization, and its application is greatly limited. The use of photocatalytic degradation of pollutants as a new and potential desulfurization technology has become a hot spot in environmental protection scientific research. However, man...
