An efficient photocatalytic system with earth abundant carbon dots and a series of cobalt thiosemicarbazone catalysts was designed and studied. All prepared photocatalysts produced hydrogen, reaching a rate of 358 μmol gNCdot−1 h−1 upon light irradiation in water.

Ligand-based electronic effects on the electrocatalytic hydrogen production by thiosemicarbazone nickel complexes
hydrogen. Over the four nickel complexes that were obtained, the one with the thiomethyl substituent, NiSCH3, was found to overtake the catalytic performances of the parent complex NiOCH3 featuring lower overpotential values and similar maximum turnover frequencies. These results confirm the electroniceffects of the ligand on HER when using thiosemicarbazone nickel complexes and support that chemical modifications
