recommendations! Published in 2017 at "Korean Journal of Chemical Engineering"

DOI: 10.1007/s11814-017-0237-4

Abstract: Various thin films for photoelectrochemical (PEC) water splitting were prepared and their PEC performance was tested. The precursor solutions for WO3 and BiVO4 photocatalysts were synthesized by solution processes, and the graphene oxide (GO) was… read more here.

recommendations! Published in 2019 at "Applied Catalysis B: Environmental"

DOI: 10.1016/j.apcatb.2018.12.058

Abstract: Abstract Different WO3 facets have different surface energies and electronic structures, and exhibit different water oxidation abilities and photocatalytic performance as a result. Because of the material’s limited photoresponse region, loading a narrow bandgap material… read more here.

recommendations! Published in 2021 at "ACS Applied Energy Materials"

DOI: 10.1021/acsaem.1c01623

Abstract: Photoelectrochemical solar energy conversion offers a way to directly store light into energy-rich chemicals. Photoanodes based on the WO3/BiVO4 heterojunction are most effective mainly thanks to the efficient separation of photogenerated charges. The WO3/BiVO4 interfacial… read more here.

DOI: 10.1021/acsenergylett.7b00216

Abstract: Due to its ∼2.4 eV band gap, BiVO4 is a very promising photoanode material for harvesting the blue portion of the solar light for photoelectrochemical (PEC) water splitting applications. In WO3/BiVO4 heterojunction films, the electrons… read more here.

DOI: 10.1039/c7ra03491a

Abstract: We report on a novel butterfly wing-like WO3/BiVO4 heterojunction for photocatalytic water splitting, in which BiVO4 is the primary visible light-absorber and WO3 acts as an electron conductor. The heterojunction, which is prepared by a… read more here.

DOI: 10.3390/app8101765

Abstract: The performance of a BiVO4 photoanode is limited by poor charge transport, especially under front side illumination. Heterojunction of different metal oxides with staggered band configuration is a promising route, as it facilitates charge separation/transport… read more here.
