Summary: Coal combustion is a major pathway for lead entering the ecological environment, and fly ash cenospheres (FACs) prepared from waste of coal-fired power plants are ideal materials for Pb sorbents due to their high strength, light weight and low price. The adsorption and reaction mechanisms of FACs and several Si-Al-based sorbents for Pb vapors were studied at high temperatures, showing that FACs have the highest adsorption capacity.

Summary: Simultaneous oxidation of benzyl alcohol and reduction of p-dinitrobenzene were achieved using Gd-doped TiO2 nanorods decorated with PoPD nanowires. The doping of Gd induced surface defects and the incorporation of PoPD enhanced the light absorption capability and electron conductivity of TiO2. Selective oxidation of benzyl alcohol yielded benzaldehyde, while selective reduction of p-dinitrobenzene yielded p-nitroaniline or p-phenylenediamine, depending on the solvent used. This work demonstrates the importance of utilizing photogenerated charge carriers and the role of solvent in selective organic transformations.

Summary: Fly ash, as a by-product of the combustion of organic matter, is readily available and cheaply generated. Researchers have studied the use of fly ash as a support for photocatalysts in wastewater treatment due to its good adsorption capacities. Fly ash-based nanocomposites have shown excellent degradation efficiencies, with SiO2, TiO2, and Al2O3 present in fly ash playing a crucial role in the degradation of dyes. Factors affecting degradation, kinetic studies, and methods to enhance photodegradation efficiency have also been discussed.

Summary: In this study, cenospheres separated from high-calcium class C fly ash produced in Thailand were analyzed for metal and trace element leaching, showing a decreasing trend in concentrations of specific elements in leachates obtained from the toxicity characteristic leaching procedure (TCLP). All concentrations were found to be below the permissible limit values according to Thailand soil quality standards. The association of heavy metal trace elements in cenospheres and fly ash was discussed in terms of physico-chemical-geochemistry correlating with the leaching concentrations.

Summary: This study investigates the effects of fly ash cenosphere (FAC) incorporation on the properties of lightweight Engineered geopolymer composites (EGCs). The results show that the addition of FAC can reduce the density of the composites while maintaining satisfactory compressive strength. Increasing the FACs/binder ratio preserves the tensile strength of the EGCs, and the presence of fractured unreacted FACs and partially hollow reacted FACs enhances the crack control ability of EGCs with higher FAC replacement or FACs/binder ratios.

Summary: Multifunctional N-Bi-O sites are prepared in BiOBr nanosheets to regulate the key steps in photoconversion, such as exciton generation and dissociation, directed transfer to active center, and oxidation capacity. The presence of these sites enhances Coulomb force, increases exciton concentration, and forms low-oxidation-state active centers for selective reaction and hole capture. Additionally, fast electronic recombination channels facilitate rapid exciton dissociation and synergistic attraction to low-oxidation-state active centers. This work achieves selective photoconversion of TC into CO with a yield of 43.53 μmol/g and CO proportion of 16.21%.
