Summary: A series of La1-xSrxMnO3 samples were prepared using sol-gel method for the degradation of rhodamine B (RhB) in water. Sr doping enhances the degradation ability of LaMnO3 for RhB, but all samples show similar degradation rate within a certain time range, and pH value can affect the degradation efficiency of RhB.

Summary: In this study, a cost-effective magnetic carbon-supported Fe@Ti composite was synthesized and used as a highly efficient persulfate (PS) activator for wastewater purification. The Fe@Ti/C-4 composite showed the best catalytic performance, effectively degrading Rhodamine B in wastewater. The presence of oxygen vacancies in the composite promoted electron transfer and played a key role in generating reactive oxygen species (ROS) for efficient degradation of organic pollutants.

Summary: Annually, a large amount of waste is generated from granite production sites, causing severe environmental and health-related problems. This study utilized granite waste to synthesize polyaniline nanofibers for the catalytic reduction of pollutants in water. The reduction reactions followed pseudo-first-order kinetics, and the produced nanofibers showed promising potential in removing hazardous water pollutants.

Summary: In this study, pure and palladium doped 12-tungstophosphoric acid and its cesium salts were prepared and characterized, determining optimal reaction temperature and the impact of palladium on coke content during ethanol dehydration. By supporting HPW and PdyPW on mesoporous molecular sieve SBA-15, catalytic activity in ethanol dehydration reaction was improved, with palladium doping significantly decreasing coke deposit formation.

Summary: This study distinguishes between the homogeneous and heterogeneous catalytic mechanisms of Pd catalytic systems in the Suzuki-Miyaura reaction, providing convincing evidence for reactions proceeding simultaneously through both mechanisms. The use of ligand-free conditions suggests that the reaction proceeds in the solution phase through a homogeneous mechanism even when heterogeneous precursors are used, based on differential selectivity under competition conditions.

Summary: TiO2 was synthesized by precipitation method and characterized. Diverse materials with different surface, structural and surface properties were obtained and evaluated in the photodegradation of RhB and the photocatalytic conversion of glycerol. The results showed that the calcination temperature affected the surface area and phase transformation, which in turn influenced the photocatalytic efficiency of the materials.

Summary: Co/Fe co-doped porous graphite carbon (Co/Fe-PGC) nanocomposites were successfully prepared and utilized for the efficient degradation of rhodamine B, achieving high removal rates of color and TOC, ultimately degrading it into harmless CO2 and H2O. The excellent catalytic performance of the catalyst is mainly attributed to the coupling effect between microelectrolysis and Fenton reaction, as well as the promotion of cobalt on electron transport and Fe2+ reduction.

Summary: Soft robotics is a rapidly growing research field that focuses on developing robots with bioinspired mechanisms and flexible materials. In this study, a self-healing catalytic soft robot was developed using hydrogels and catalytic reactions. The robot's movement was driven by fluidic release resulting from reactions with hydrogen peroxide. The speed of the robot could be controlled by adjusting the concentration of hydrogen peroxide and the folding/unfolding of enzymes. The addition of iron oxide nanoparticles allowed for magnetic guidance, and different module combinations enabled different motion modes.
