1. A method for preparing a bimetallic perovskite loaded graphene-like carbon nitride photocatalyst, comprising the following steps of:
(11) dissolving SbCl3 and AgCl solid reagents in a beaker containing HCl solution under constant stirring and heating; then, adding CsCl in the heated solution to form sediment on the bottom of the beaker; collecting the sediment and washing the sediment with ethanol and finally drying in an oven; after cooling the oven to room temperature, taking out to obtain Cs2AgSbCl6 powder;
(12) adding melamine to an aluminum oxide crucible and covering the aluminum oxide crucible with a lid, placing the aluminum oxide crucible in a muffle furnace for calcination in static air, and finally after cooling to room temperature naturally, collecting g-C3N4 sample;
(13) adding the Cs2AgSbCl6 powder and the g-C3N4 to a solvent, stirring after subjecting to ultrasound, and directly centrifuging followed by drying to obtain the bimetallic perovskite loaded graphene-like carbon nitride photocatalyst,
wherein a mass ratio of Cs2AgSbCl6 powder to g-C3N4 in step (13) is (0.0016-0.016): 0.8.
