▎ 摘  要

NOVELTY - Preparing nano- copper sulfide -loaded sulfur and nitrogen co-doped graphene aerogel comprises (S1) dispersing 0.1-1 g thiourea and 0.01-0.1 g copper sulfide nanoparticles in a 20-500 ml graphene oxide solution with a concentration of 0.1-10 g/l, and ultrasonically processing for 30-180 minutes, (S2) adding the mixture into an autoclave, heating at 90-200 degrees C for 5-24 hours to generate graphene hydrogel, (S3) washing the obtained graphene hydrogel in a 1-90% alcohol solution for 5 times, soaking for about 4 hours each time, (S4) freeze-drying the washed hydrogel using a freeze dryer for 48 hours to obtain sulfur-nitrogen co-doped graphene aerogel loaded with copper sulfide nanospheres. USE - The nanospheres is useful in degrading organic pollutants (claimed). ADVANTAGE - The method can efficiently degrade the adsorbed organic matter and improves the adsorption saturation and secondary release in the existing graphene aerogel. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for sulfur-nitrogen co-doped graphene aerogel loaded with copper sulfide nanospheres.
