- W4386853534 abstract "Photoelectrochemical cells (PECs) enable the molecular synthesis, utilizing light energy and storing the charges into chemical bonds. In this way, PECs provide a renewable route to produce chemical fuels for carbon neutrality. Although various studies have been intensively conducted to achieve commercially viable PEC performance and costs, there are still several challenges for wide commercialization due to the complex functionality and connectivity in electrolyte∣catalyst∣semiconductor interfaces. Especially, more cautions are necessary when non-Pt group materials (NPGM) are utilized as catalysts. Much higher loading of NPGM is required than the one of PGM to compensate the relatively lower electrocatalytic activity, resulting in other issues including parasitic loss of photons. Here, functional integration of catalysts onto the semiconductor surface and analysis of the electrolyte∣catalyst∣semiconductor interface will be presented. The chemical compositions and spatio control of catalysts lead to the improved photoelectrochemical performance toward water splitting, resulting from the optimization of light absorption and transport/transfer of photogenerated charge carriers in crystalline silicon and hematite (α-Fe 2 O 3 ). Furthermore, the impact of this catalyst manipulation is analyzed through electrochemical impedance and Raman spectroscopy to study the photoelectrochemical reaction pathways." @default.
