In this work, Type-II heterojunction was constructed between g-C3N4 and BiOI by ultrasonically assisted hydrothermal synthesis for photoelectrochemical water splitting. The g-C3N4 was decorated on BiOI microspheres with a well-defined...
A heterostructured TaON/Ta3N5 photoanode exhibits a 350 mV negative shift of photocurrent onset potential to 0.65 V versus the reversible hydrogen electrode.
