Summary: This study explores the catalytic performance of Pd nanocrystals doped with Pb in direct H2O2 synthesis. It is found that Pd3Pb cubes outperform other shapes of Pd3Pb nanocrystals and monometallic Pd catalysts in catalytic efficiency. DFT calculations and surface studies reveal that the electronic modification and lack of larger Pd ensembles in Pd3Pb cubes contribute to their superior catalytic activity in H2O2 synthesis.

Summary: This study presents a method for fabricating metakaolin-based geopolymers that can maintain their structural and mechanical stability up to 600 degrees C. The chemical composition of the geopolymers was analyzed using thermogravimetric analysis and Fourier-transform infrared spectroscopy. The presence of residual free water led to damage when exposed to high temperatures, so the curing temperature was increased to remove water during the curing process. A correlation was found between the formation of Si-O-Al linkage and the position of fingerprint peaks in infrared spectra, providing a means to evaluate the extent of geopolymerization. The flexural and tensile properties of the geopolymers were measured at different temperatures, and it was found that the metakaolin-based geopolymers cured at 120 degrees C remained mechanically stable up to 600 degrees C.

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.
