Low isolation efficiency of photogenerated electron-hole pairs and inadequate utilization of visible light limit the application of g-C3N4 nanosheets (CNNs) in photocathodic protection (PCP). Therefore, indium zinc sulfide (ZnIn2S4, ZIS) nanolayers with nano-leaf structures were fabricated on CNNs using a simple hydrothermal method and used as visible light sensitizer and electron donor to improve its PCP performance. Under visible light illumination, the 30% ZIS@CNNs photoelectrode coupled with 316 stainless steel (SS) exhibited the largest photocurrent density of 17.30 μA cm−2 and the highest potential drop of 0.37 V, which was approximately 4 and 7.5 times higher than that of pure CNNs, respectively. The improvement in protection performance may be attributable to the crucial increase in visible light absorption and the terrific enhancement in rapid migration pathways provided using heterogeneous junctions.

The reliability and oxidation kinetics behaviour of the Haynes-230 alloy used in hot combustion components for very long-term applications are of great interest to researchers. To recreate the real-time environment, the in situ surface oxidation behaviour of Haynes-230 alloy at high temperature exposures (800, 1000, and 1200°C) is studied in a customized furnace setup equipped with electrochemical impedance spectroscopy (EIS). The heat-treated samples' phase analysis, surface morphology, and chemical composition were evaluated using X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive X-ray spectroscopy (EDS). The various forms of surface oxide layer formation were investigated using Raman spectroscopy. The EIS method was also utilized to evaluate the oxidation behaviour of Haynes-230 at various temperatures and time durations. Furthermore, the oxidation kinetics were investigated under thermal loading and unloading conditions, and capacitive behaviour was observed under unloading conditions.
