Hematite photoanode
WebHere we report a Co-doped carbon layer on hematite to significantly enhance the solar water oxidation performance, which shows a large cathodic onset potential shift of 300 mV representing one of the largest values ever reported for hematite photoanodes. The final photocurrent at 1.23 V vs. RHE can also achieve a high value of 2.24 mA/cm 2. WebOne-dimensional zinc oxidizer nanorods array exhibit excellent electron mobility and thus take outstanding potential as photoanode for photoelelctrochemical water splitting. However, the poor absorption of visible light and the distinguished surface recombination hider the energy improvement. In this work, Au nanoparticles and aluminium oxide were …
