Polyethylenimine-grafted graphene oxide: a versatile photothermal nanocomposite for catalysis and carbon dioxide capture-and-release under simulated and natural sunlight

Application of solar thermal energy relies on photothermal effect is one of the emerging topics in green chemical research. Polyethylenimine-grafted graphene oxide (PEI@GO) can harvest thermal energy directly from visible light and be employed as photothermal catalyst in model reactions. Furthermore, this nanocomposite used in carbon dioxide capture-and-release processes relied on photothermal regeneration. Graphical abstract
