Summary: In this study, a water-in-oil emulsion-assisted assembly method was proposed for the controlled preparation of 3D flower-like Ti3C2Tx microspheres with high electrochemical performance. By adjusting the volume ratio of water and oil, the structure and size of the microspheres can be controlled. The resulting microspheres exhibit a large specific surface area and good ion diffusion pathway, showing excellent specific capacitance and long-term cyclic stability as supercapacitor electrodes.

Summary: This study presents a facile and scalable synthesis method for carbon microspheres with a unique hierarchically structured flower-like morphology. These carbons exhibit high CO2 capacity, attractive CO2/N-2 selectivity, and ease of regeneration. Detailed analysis reveals that the CO2 capacity is strongly correlated with the volume of ultra-micropores, rather than surface area or total pore volume. These materials show promise as efficient and cost-effective CO2 sorbents due to their hierarchical structure, low isosteric heats of adsorption, and easy temperature and pressure-swing-based cyclic regeneration.

Summary: Researchers aim to increase the silver ion adsorption capacity of chelate resin, and this study prepared flower-like thiourea-formaldehyde microspheres (FTFM) with enhanced adsorption performance. The nanoflower-like microstructure exhibited a significantly higher specific surface area and silver ion adsorption capacity compared to the control. Kinetic and isotherm studies further supported the superior adsorption ability of FTFM. Due to its high absorption efficiency, convenient preparation, and low cost, FTFM is recommended for industrial applications.

Summary: A magnetic recyclable ZnFe2O4/BiOBr (ZFB) heterojunction microspheres with oxygen vacancies were prepared, which showed improved separation efficiency and utilisation of photogenerated carriers. The ZnFe2O4 induced the growth of nanolayer structure on the surface of BiOBr, leading to increased diffraction peak intensity ratio and specific surface area. The ZFB exhibited a smaller bandgap, wider visible response range, and higher photogenerated carrier migration and separation efficiency compared to BiOBr. It could effectively degrade organic molecules such as Rhodamine B, norfloxacin, and sulfadiazine, with degradation efficiencies above 86.64%. The ZFB photocatalytic material demonstrated high recyclable efficiency and potential for simultaneous degradation of various micropollutants in organic wastewater.
