SubPc 3/TiO2 shows the best photocatatytic activity with a hydrogen evolution rate of 1396 mu mol h(-1), which is much higher than that of SubPcs 1 and 2 (771 and 658 mu mol g(-1) respectively). This work clearly shows that considering their optical and redox properties, SubPcs are promising candidates for light-driven water splitting systems.eninfo:eu-repo/semantics/closedAccessVisible-LightSubphthalocyaninesGrapheneWaterMos2Article10.1039/d0dt02565h49361255012554Q2WOS:0005719799000042-s2.0-85091469989Q2
