摘要：
An organic triplet-triplet annihilation upconversion system consting of Ir(coumarin-6)2(acac) and TIPS-naphthalene is used to drive overall water-splitting using the UV-active photocatalyst Rh/Cr2O3/CoOOH/Al:SrTiO3. Light from 455 and 470 nm LEDs was upconverted to 355-410 nm at 6.1% efficiency. Hydrogen production doubled at 455 nm and tripled at 470 nm, compared to controls.
