Summary: Co-Fe, Cu-Cr, and Co-Mn mixed oxide catalysts were prepared using a one-pot hard template synthesis method, and their catalytic performance significantly improved after rearrangement of the template, with increased specific surface area and reducibility. The CoMn catalyst showed the most promising catalytic performance with a reduced 100% conversion temperature. However, the presence of water vapor was found to decrease the activity and stability of the catalyst, with a calculated activation energy of 59.5 kJ/mol for the Co-Mn catalyst, confirming the MVK mechanism as the most probable reaction mechanism.

Summary: The state-of-the-art Ammonia Slip Catalyst (ASC) has a dual-layer washcoat architecture with a bottom layer of Pt/Al2O3 and a top layer of Cu/SSZ-13. A trade-off between the NH3 conversion and N-2 selectivity presents a challenge in the ASC design. The best results are obtained with the combination of a base mixed layer that provides for effective coupling between Pt and Cu active sites and a top Cu/SSZ-13 layer of an intermediate thickness and nominally half of the total Cu loading.

Summary: Researchers have gained considerable insight into the power absorption mechanisms of single-domain magnetic nanoparticles (MNPs) in magnetic hyperthermia applications. However, the role of magnetic relaxation parameters is still debated. This study explores the role of magnetic anisotropy and site selective substitution in magnetic relaxation, emphasizing the importance in hyperthermia treatment. Additionally, the introduction of Eu ion positively influenced the heating efficiency of magnetite systems, indicating a potential for improved hyperthermia therapy.

Summary: The composite catalyst CoFe2O4/CuO was successfully prepared and showed excellent activation performance for peracetic acid (PAA) and removal efficiency of sulfamethoxazole (SMX) under neutral conditions. The valence state of Co played a crucial role in the activation of PAA, and organic radicals (R-O center dot) dominated the removal of SMX. The CoFe2O4/CuO catalyst achieved a relatively rapid degradation of SMX and was more effective than CoFe2O4 or CuO alone.

Summary: Deposition of copper by TIE method results in samples containing highly dispersed copper species and CuO nanorods, while deposition of highly dispersed copper species inside pores can be achieved through the TIE-NH3 procedure. Samples obtained by TIE-NH3 method are found to be promising catalysts for low-temperature NH3-SCR process.

Summary: In this study, nano crystalline copper ferrite was successfully prepared using combustion synthesis with coir fibers and corn leaves as templates. The effects of various parameters on product properties were investigated, leading to the determination of optimal conditions for crystallite size, morphology, and magnetic properties. The XRD analysis revealed tetragonal structures and average crystallite sizes between 23.1 nm and 34.1 nm for the CuFe2O4 powders synthesized.

Summary: This paper focuses on the key factors contributing to pore formation in hard-templated macroporous alumina, with special attention to the formation of a connected pore structure. It was found that a hard template made of polymeric particles can fix the pore size and shape, sinter small pores of the material, and create additional channels to connect macropores. A connected pore system can be formed by adding more than 20 wt% of the polymeric template, regardless of the type of template and Al2O3 precursor.
