Abstract |
Cation doping and heterojunction formation in semi-conductors are often studied to improve efficiency and stability of photoelectrochemical (PEC) water splitting electrodes and catalysts. For example, Molybdenum doped BiVO4 can improve photo reaction currents, and ZnO/BiVO4 heterojunction can improve PEC performance. In this poster, we present sol-gel synthesized lithium and molybdenum co-doped BiVO4(Li-Mo:BiVO4) with WO3heterojunction (denoted as Li-Mo:BiVO4/WO3) that shows enhancement of PEC water oxidation, increasing current density from 1.0 to 2.8 mA/cm2 (at 1.6 V vs. RHE) and also decrease band-gap from 2.66 to 2.24 eV compared to pristine Mo:BiVO4. |
