boosting ethanol electrooxidation of agsrtio3 in the dark from the electro-photocatalytic “memory effect”

The cost and efficiency of the electro-photocatalyst have a direct impact on the practical use of fuel cells which are inexpensive and highly effective. therefore, it is crucial to design a reasonably priced electro-photocatalyst. electro-photocatalysts with memory effect, which can maintain electrocatalytic performance in the dark, have been the subject of recent research. the perovskite structure of srtio3 is characterized by its strong electro-photocatalytic activity, broad surface area, low toxicity, and low cost. due to a restricted capacity for electron storage, electro-photocatalysts with memory effect activities are minimal. as a result, doping srtio3 with cations like ag can change its electrical characteristics, increasing electro-photocatalytic activity. to explore the electro-photocatalytic memory effect of the ag-doped srtio3, we developed a sonochemical approach for its manufacture. x-ray diffraction (xrd), ultraviolet-visible diffuse reflection spectroscopy (uv-vis), transmission electron microscopy (tem), scanning electron microscopy (sem), and fourier transform infrared spectroscopy (ft-ir) were used to investigate the ag-doped srtio3 nano-photocatalyst. doping srtio3 with ag allowed us to create an ag-doped srtio3 nano- electrophotocatalyst. under light and after illumination, the ag-doped srtio3 nanophotocatalyst showed excellent performance in ethanol electrooxidation in aqueous alkaline media. the effects of temperature, ph, amount of electro-photocatalyst, and ethanol solution concentration on the photocatalytic activity were examined. it can be speculated that this work paved the way for the engineering and design of electro-nanocatalysts to be employed in high-performance defcs.keywords: ethanol electrooxidation, memory effect, electro-photocatalyst, fuel cells.
