A specially designed twin photoreactor, which integrates the water splitting and the degradation of isopropanol, can simultaneously carry out the degradation of isopropanol and hydrogen production. A flux method was conducted to prepare Rh@CrO3 cocatalyst on Al3+ doped high-crystallinity strontium titanate for the photocatalyst of hydrogen evolution. Nearly 1200 μmole/g of hydrogen was evolved in photocatalytic whole water splitting in five hours under simulated AM 1.5 G sunlight. Pt-loaded WO3 was utilized to degrade 100 ppm isopropanol solution. The above photocatalysts were used in the twin reactor with electron-mediator I-/IO3- and a Neosepta anion-exchanged membrane. Hydrogen evolution of 1102 μmole/g and isopropanol removal of 10.1% were achieved in five hours, indicating the rate-limiting H2 rate was overcome. The quantum efficiencies on the hydrogen-evolution and degradation sides were estimated to be 0.102% and 0.123%, respectively.Isopropanol degradation | Perovskite | Photo twin reactor | Water splitting | Z-scheme[SDGs]SDG6[SDGs]SDG7journal article10.1016/j.apcatb.2022.1221832-s2.0-85142784145WOS:000891647900004https://api.elsevier.com/content/abstract/scopus_id/85142784145
