To characterize the developed materials, we conducted SEM, TEM, EDS-TEM, XRD. Due to a large surface-active area of developed material and its support for Pt nanoparticles in diameters of 2–3 nm, the WO3/Pt electrode indicated as a greater electrochemical catalyst for the redox reaction than Pt and WO3 CEs. Thus, the power conversion efficiency for a device with WO3/Pt electrode is improved to 8.10%, compared to 4.36% for a device with WO3 electrode and 7.61% for a cell with a Pt electrode. This study also supplies a procedure for fabricating highly catalytic and low-price catalyst materials for CEs, which has a tremendous meaning for various applications of micro-wheels consisted of self-assembled WO3 nanorods integrated with platinum. 2021-06-15T02:36:04Z 2021-06-15T02:36:04Z 2021 Article Working Paper https://www.sciencedirect.com/science/article/abs/pii/S0038092X2031241X?via%3Dihub#! https://dlib.phenikaa-uni.edu.vn/handle/PNK/1759 https://doi.org/10.1016/j.solener.2020.11.070 en application/pdf Solar Energy
