Summary: We demonstrate a composite photocatalyst for nitric oxide conversion with a Cu-Fe alloy, graphitic carbon nitride (g-C3N4), and ZnIn2S4. The superior photocatalytic performance of 6.45-fold that of g-C3N4 was confirmed. The delay effect on charge recombination was observed through time-resolved photoluminescence, and heterojunction establishment was attributed to the hole-trapping ability of ZnIn2S4. The combined effects of the Cu-Fe alloy were confirmed by NO-specific adsorption and conversion experiments, and the active species involved were examined via electron spin resonance. Density functional theory calculations revealed the molecular mechanisms of photocatalytic conversion of NO to NO3-. Therefore, g-C3N4|ZnIn2S4|CuFe has potential for sustainable and efficient pollutant conversion.

Summary: The impact of the piezoelectric effect on the photocatalytic production of hydrogen peroxide (H2O2) over graphitic carbon nitride (CN) was investigated by modulating its molecular structure. The results showed that the photocatalytic activity of CN, CN-P, CN-OF was enhanced by approximately 1.40, 1.46, and 1.51 times due to the piezoelectric effect, respectively, while CN-CA exhibited a 6-fold decrease in activity. Various techniques were employed to explore the active sites, piezoelectric polarization, and charge separation, revealing that the piezoelectric effect's influence on photocatalytic H2O2 production over CN is determined by multiple factors.

Summary: With the development of metallurgy, chemical manufacturing, and mining, lead pollution in water, especially from battery industries, has become a serious environmental problem. In this study, a highly efficient removal of Pb2+ from wastewater was achieved using MoO2@N-doped hollow carbon sphere (MoO2@ NHCS) anodes in a capacitive deionization (CDI) process. The MoO2@NHCS electrodes exhibited a high adsorption capacity of 202.14 mg/g for Pb2+ in a 50 ppm solution (pH = 6 and U = 1.2 V). Additionally, the electrodes showed selectivity towards Pb2+ even in the presence of Na+ and other heavy metal ions. The selective removal was attributed to the transformation of octahedral MoO2 into tetrahedral [MoO4]2-, which could effectively trap Pb2+ to form PbMoO4.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
