NOVELTY - Preparing graphitic carbon nitride/molybdenum disulfide nanosheet/graphene oxide ternary composite catalyst comprises e.g. adding 20-30 pts. wt. molybdenum disulfide into ball mill bottle filled with certain amount of zirconia beads, adding 65-75 pts. wt. N-methyl-2-pyrrolidone and ball milling, grinding ball mill, taking out mixed solution, sonicating for 9-11 hours, and centrifugating to obtain molybdenum disulfide nanosheet solution, placing 15-25 pts. wt. melamine in crucible, calcining to obtain block of graphitic carbon nitride, and then grinding in agate mortar for 40-50 minutes to obtain graphitic carbon nitride powder, placing 10-20 pts. wt. graphite oxide in beaker, adding 60-70 pts. wt. deionized water and 45-55 pts. wt. absolute ethanol to obtain graphene oxide solution, adding 15-25 pts. wt. molybdenum disulfide nanosheet solution and 10-20 pts. wt. graphitic carbon nitride powder into ball mill jar, grinding ball and ball milling, filtering and washing, and drying. USE - The method is useful for preparing graphitic carbon nitride/molybdenum disulfide nanosheet/graphene oxide ternary composite catalyst. ADVANTAGE - The method is simple and easy to operate, and composite catalyst has excellent catalytic activity. DETAILED DESCRIPTION - Preparing graphitic carbon nitride/molybdenum disulfide nanosheet/graphene oxide ternary composite catalyst comprises adding 20-30 pts. wt. molybdenum disulfide into ball mill bottle filled with certain amount of zirconia beads, adding 65-75 pts. wt. N-methyl-2-pyrrolidone and ball milling for 47-49 hours, grinding ball mill, taking out mixed solution, sonicating for 9-11 hours, and centrifugating for 35-45 minutes to take the supernatant to obtain molybdenum disulfide nanosheet solution, placing 15-25 pts. wt. melamine in crucible, calcining at 510-530 degrees C for 5-6 hours to obtain block of graphitic carbon nitride, and then grinding in agate mortar for 40-50 minutes to obtain graphitic carbon nitride powder, placing 10-20 pts. wt. graphite oxide in beaker, adding 60-70 pts. wt. deionized water and 45-55 pts. wt. absolute ethanol respectively, and performing ultrasonication for 2.5-3.5 hours to obtain graphene oxide solution, adding 15-25 pts. wt. molybdenum disulfide nanosheet solution and 10-20 pts. wt. graphitic carbon nitride powder into ball mill jar, grinding ball with ball to ball ratio of 10:1 and ball milling for 5-7 hours using planetary ball mill, filtering and washing, and drying at 85-95 degrees C for 6-8 hours.
