Summary: In this study, nontoxic Ce was used for co-doping to reduce the dopant amount of highly toxic Sb, resulting in an enhanced oxidation ability of SnO2 reactive electrochemical membrane (REM) for atrazine (ATZ) herbicide. Co-doping Ce caused expansion of SnO2 crystal and the creation of defects on the SnO2 crystal surface, leading to increased catalytic activity. The Sb, Ce co-doped SnO2 REM reduced ATZ in groundwater samples from an initial concentration of 10 μg/L to below the regulatory maximum level of 14 nM. The addition of chloride and natural organic matters inhibited ATZ oxidation, while pH and bicarbonate had less effect. Hydroxyl radical (& BULL;OH) played a key role in ATZ oxidation, and degradation by-products were identified and proposed.

Summary: This study prepared a novel Fe-Ti-chitosan composite (FTC-2/1) via a facile coprecipitation method for efficient elimination of Sb(III) and Sb(V) in water. The FTC-2/1 exhibited abundant surface hydroxyl groups and a unique three-dimensional porous structure, promoting the diffusion kinetics of Sb(III) and Sb(V). Density functional theory calculations revealed that the highest adsorption efficiency of FTC-2/1 was attributed to the preferential adsorption of the Fe-Ti bidentate complex towards Sb(III) and Sb(V) and the electronic structure reconstruction of the adsorbed antimony molecules and Fe-Ti atoms.

Summary: Passive daytime radiative cooling (PDRC) technology, while promising for global spacing cooling, faces limitations in practical application due to reduced cooling effectiveness caused by wear and dirt contamination. Researchers have developed a renewable armor structure using fluorinated hollow glass microspheres to enhance the anti-fouling and cooling properties of PDRC coatings. The coatings exhibit high solar reflectance and thermal emittance, leading to significant temperature reduction below ambient temperature.
