The Photoelectrochemical(PEC) glycerol oxidation is not only economical by converting low-cost glycerol into a high-cost product but also environmentally friendly by reducing carbon dioxide emissions. Nowadays, high-efficiency electrocatalysts are attracting attention as they play an important role in the oxidation of glycerol. Bi-based Metal-organic frameworks (MOFs) is a promising candidate of electrocatalyst because it promotes bulk charge separation and surface charge transfer in the PEC oxidation reaction with an ultra-large surface area of porous crystals. In this study, we successfully fabricated a WO3 nanowire film decorated with Bi-MOFs for glycerol oxidation. Without any change in the structure of the WO3 layer, the photocurrent performance of WO3 decorated with Bi-MOFs, which decomposes glycerol, was improved by 2.25 times compared to that of bare WO3 with water splitting. In addition, the operational stability was improved as the Bi-MOFs improved the charge transfer ability and prevented the photodegradation of the WO3 layer |
