Fig. 3: Catalyst recyclability and substrate study.
a, Recycling performance of the catalyst for the photocatalytic reduction of nitrobenzene. Reaction conditions were 0.1 mmol nitro compound, 50 µl hydrazine hydrate, 10 mg catalyst, 3 ml ethanol and light irradiation with continuous stirring at room temperature for 4 h. b, Photocatalytic reduction of nitroarenes to anilines catalysed by CuFeS2 NCs. The percentiles correspond to the reaction yields, as determined by gas chromatography. Reaction conditions were 0.1 mmol nitro compound, 50 µl hydrazine hydrate, 10 mg catalyst, 3 ml ethanol and light irradiation with continuous stirring at room temperature for 4 h. The asterisk (a) denotes 1 mmol nitroarene, 1 ml hydrazine hydrate and 2 mg catalyst under light irradiation with continuous stirring at room temperature for 4 h.
