HETERODIMERIC SYSTEM FOR VISIBLE-LIGHT HARVESTING PHOTOCATALYSTS

摘要

Heterodimeric photocatalytic systems and methods of making and using the same are disclosed. The systems can include a first nanomaterial comprising titanium dioxide (TiO₂) having a first bandgap energy characterized by a first highest occupied molecular orbital (HOMO) and a first lowest unoccupied molecular orbital (LUMO). The systems can further include a second nanomaterial comprising semiconducting metal oxide and/or metal sulfide (MO_X/MS_X) having a second bandgap characterized by a second HOMO and a second LUMO, wherein the second bandgap energy is in the range of energies for a visible light spectrum, and the second LUMO is higher than the first LUMO.
