Metal-free carbocatalyst for catalytic hydrogenation of N-containing unsaturated compounds

Probing Activity Enhancement of Photothermal Catalyst under Near-Infrared Irradiation

“…25 °C), which suggested the structural rupture of CR and MO molecules and their decolorization. 36 When light irradiation was applied in the catalysis, the reaction time decreased to 15 and 10 min and the temperature increased to 38.1 and 34.4 °C accordingly (Figure S9c−e and S9h−j). These results demonstrated the photothermally promoted hydrogenation activity of Bi 2 S 3 @ NC@Pd catalyst.…”

“…The aqueous solutions of CR and MO show characteristic bands located at 498 and 462 nm, respectively. , Time-dependent decreases in the absorbance of CR and MO with complete disappearance of peaks (498 and 462 nm) were observed within 20 and 12 min (Figure S9a, S9b, S9f, and S9g) at room temperature (ca. 25 °C), which suggested the structural rupture of CR and MO molecules and their decolorization . When light irradiation was applied in the catalysis, the reaction time decreased to 15 and 10 min and the temperature increased to 38.1 and 34.4 °C accordingly (Figure S9c–e and S9h–j).…”

Recent advances in metal-free heteroatom-doped carbon heterogonous catalysts

“…Xi and co-workers 191 described a simple one-pot hydrothermal synthesis procedure for the preparation of an effective nitrogen-doped holey graphene (NHG), in which graphene oxide was served as a starting material, NH 3 as a nitrogen source, and hydrogen peroxide as etching agent ( Fig. 6 ).…”
