Embodiment 1
[0025] A preparation method of a photocatalytic nanocomposite catalyst, comprising the following steps:
[0026] Weigh 0.008mol of lanthanum nitrate, 0.008mol of aluminum nitrate and 0.084mol of SrTiO, respectively 3 , mixed and ground in an agate mortar for 1 hour, the ground mixture was placed in a ball mill, ball milled at 4000 revolutions for 10 hours, and then 1 mol of SrCl was added. 2 Continue ball milling for 1 hour; sieve and separate the ball-milled mixture, place it in a muffle furnace, keep it at 800 degrees for 12 hours, take it out, filter and wash it with a large amount of deionized water, and then place the material in a drying box at 80 degrees Dry overnight to obtain La,Al-SrTiO 3 Nanoparticles; La,Al-SrTiO 3 With the mass ratio of 2.0wt% (NH 4 ) 2 WS 4 WS formed after 800 degree pyrolysis peeling 2The nanosheets and chromium salts were uniformly ground and mixed for 4 hours, and kept at 500 degrees for 4 hours under the protection of inert gas to obtai...
Embodiment 2
[0029] A preparation method of a photocatalytic nanocomposite catalyst, comprising the following steps:
[0030] Weigh 0.005mol of lanthanum nitrate, 0.005mol of aluminum nitrate and 0.09mol of SrTiO respectively 3 , mixed and ground in an agate mortar for 1 hour, the ground mixture was placed in a ball mill, ball-milled at 4000 revolutions for 24 hours, and then 1 mol of SrCl was added. 2 Continue ball milling for 1 hour; sieve and separate the ball-milled mixture, place it in a muffle furnace, and keep it at 1000 degrees for 8 hours; after taking it out, filter and wash it with a large amount of deionized water, and then place the material in a drying box at 80 degrees Dry overnight to obtain La,Al-SrTiO 3 Nano catalyst material; La,Al-SrTiO 3 With the mass ratio of 1.0wt% (NH 4 ) 2 WS 4 WS formed after 400 degree pyrolysis peeling 2 The nanosheets and the chromium salt were uniformly ground and mixed for 4 hours, and kept at 400 degrees for 2 hours under the protectio...
Embodiment 3
