Summary: The textile industry is a major contributor to water pollution, particularly due to the high toxicity and chemical stability of the azo dyes used. This study focused on the degradation of Reactive Red 195 (RR195) through catalytic ozonation using a Co/Al2O3-CeO2 catalyst. Although the presence of the catalyst did not significantly enhance the degradation of RR195 compared to ozonation alone, it was beneficial for mineralization. Various factors such as initial dye concentration, catalyst dosage, and solution pH were found to affect color and COD removal, with optimal conditions determined.

Summary: Chitin was used as an adsorbent to remove Reactive Red 195 from aqueous solutions. The adsorption process was affected by pH, temperature, and initial dye concentration. The maximum dye adsorption capacity was observed at pH 3 and 50 degrees C. The adsorption data followed the Langmuir model and the kinetics were described by pseudo-first-order kinetics. The adsorption process was found to be endothermic and spontaneous.

Summary: The study focuses on the chemical modification of lotus leaf powder to create a tertiary amine type powder named DMA-LLP, which proved to be an effective adsorbent for removing Reactive Red 195 (RR 195) from aqueous environments. The Langmuir model best described the adsorption equilibrium data, and thermodynamic parameters showed the spontaneous and endothermic nature of the adsorption process. Regeneration findings indicated that DMA-LLP could be reused up to five times with a maximum removal rate of 72% achieved after the fifth cycle.

Summary: The presence of synthesized MnOx-CeOx/gamma-Al2O3 as a catalyst significantly improved the degradation of ofloxacin (OFX) in synthetic wastewater, achieving removal rates of 98.2% for OFX and 76.7% for COD. The catalyst also increased the reaction rate constant by a factor of five, demonstrating its effectiveness in enhancing the ozonation process for OFX degradation. Additionally, gas chromatography-mass spectrometry (GC-MS) results identified various small-molecule organics in the final oxidation products, highlighting the complex pathways involved in OFX degradation and mineralization.

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.

Summary: Methane chemistry is a significant area of research in catalysis. Converting methane into value-added chemicals is desirable but challenging due to its high C-H bonding energy and lack of pi bonding or unpaired electrons. Photocatalytic partial oxidation of methane to liquid oxygenates is a promising technology for achieving high efficiency and selectivity under mild conditions. The choice and activation of oxidants are crucial for its performance.
