▎ 摘  要

NOVELTY - Indium(III) oxide nanocatalyst grown on rGO, comprises a reduced graphene oxide nanosheet and an indium(III) oxide nanoribbon composited on the surface of the reduced graphene oxide nanosheet. USE - Indium(III) oxide nanocatalyst grown on rGO. ADVANTAGE - The indium(III) oxide nanocatalyst grown on rGO, where the initial activity is retained, indicating that it is still recyclable after a long period of catalytic reaction. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a method of preparing an indium(III) oxide nanocatalyst grown on rGO, which comprises dispersing sodium oleate, indium trichloride tetrahydrate and reduced graphene oxide nanosheets in deionized water, stirring uniformly to obtain a mixed liquid; reacting the mixture hydrothermally, and the obtained reaction product is washed and dried to obtain an indium(III) hydroxide nanobelt grown on rGO; and sintering the indium(III) hydroxide nanobelts grown on rGO to obtain an indium(III) oxide nanocatalyst grown on rGO; and (2) a method of carbon dioxide electroreduction reaction, which comprises mixing an ethanol, a perfluorinated resin, and an indium(III) oxide nano catalyst grown on rGO, and obtaining a uniformly dispersed catalyst after ultrasonication; and coating the catalyst ink on carbon paper, dring, and placing in a carbon dioxide-saturated 0.1 mol/L potassium bicarbonate solution as a working electrode for electroreduction.
