Investigation of the performance of an Fe2O3/g-C3N4 heterojunction photoanode in the photoelectrocatalytic oxygen evolution reaction

The Fe 2 O 3 /g-C 3 N 4 heterojunction photoanodes were constructed, which could significantly improving the photoelectrochemical water splitting efficiency of Fe 2 O 3 . The photocurrent density of the Fe 2 O 3 /g-C 3 N 4 -2 is 5.2 times that of pure Fe 2 O 3 .
