Abstract
‘Chinese peony’-structured MnIn2S4/In2O3
nanocomposites with S-scheme heterojunction were prepared, and their
dual performance of anticorrosion for steels and wastewater purification
was explored. The mechanism for the enhanced photoelectrochemical
cathodic protection (PECCP) is attributed to the introduction of
S-scheme MnIn2S4/In2O3
heterojunction, which was systematically certificated through density
functional theory (DFT) and experiments. Furthermore, MnIn2S4/In2O3
PECCP coating was synthesized to compensate for the insufficient dark
protection capability of PECCP and defined through inductively coupled
plasma (ICP). The protection efficiency of MnIn2S4/In2O3PECCP
coating was 75.33% and 96.22% for 304 stainless steel (304SS) and
hot-rolled ribbed bar 400 (HRB400) in 3.5 wt% NaCl for 54 days. In
addition, the improved mechanism for anticorrosion of the PECCP coating
was investigated by the wire beam electrode (WBE).
