Summary: This study systematically investigated the mechanism of CO oxidation on doped graphene catalysts through DFT calculations, finding that FeFe@C6, FeCo@C6, and FeNi@C6 are efficient for CO oxidation. Additionally, heteronuclear dimeric catalysts FeCo@C6 and FeNi@C6 exhibit better catalytic activity and lower energy barriers compared to homonuclear dimeric catalyst FeFe@C6.

Summary: N2O decomposition on Cu, Co, and Fe-exchanged SSZ-13 zeolite catalysts follows a dual-site mechanism or a single-site mechanism. The reaction is limited by N-O cleavage under low pressure and first-order kinetic regime. Fe-SSZ-13 exhibits lower activation barriers, leading to a higher N2O decomposition rate.

Summary: In this study, a biological method using manganese oxidizing bacteria was used to synthesize multi-metal oxides for the first time to catalyze ozonation. The catalytic activities were found to be significantly influenced by the dosage of cobalt, cultivation time, and polishing methods. The optimized Bio-FeMnCoOx catalyst showed a second-order degrading kinetic constant 4.8 times higher than that of the physiochemically synthesized peer.

Summary: Fenton reaction utilizes hydroxyl radicals generated by ferrous iron and hydrogen peroxide for degradation of emerging contaminants in water, while Fenton-like reaction uses solid catalysts instead of dissolved Fe2+ to overcome drawbacks. This review systematically summarizes various Fe-based Fenton-like catalysts, discusses their catalytic mechanisms and applications for degradation of emerging contaminants, and highlights their potential for removing toxic organic pollutants from water and wastewater.

Summary: An Fe-substituted La-hexaaluminate-supported Ir catalyst was synthesized and characterized. The loading of Ir species resulted in the formation of oxygen vacancies in the Fe-substituted hexaaluminate, promoting the preferred formation of Ir-0 species. Compared to Mg-substituted catalysts, Fe-substituted catalysts were more favorable for N2O decomposition.

Summary: In this study, an electrochemical system was used as a co-catalyst to enhance the activation of peroxymonosulfate for efficient degradation of Sulfamethoxazole. The collaboration of radicals and non-radicals oxidation was found to be responsible for the degradation, with singlet oxygen and Fe(IV) surprisingly involved in the system. The relative contributions of various reactive oxygen species were calculated, and multiple degradation pathways for Sulfamethoxazole were proposed.

Summary: A new method for accurately estimating the sliding angle of a hydrophobic surface is proposed in this study, which shows high accuracy. This method is applied to study the fluid resistance of commercial face masks, and it is found that the outermost layer of disposable surgical masks has moderate water repellency, while pre-coated fabric masks have high protection efficiency. In addition, treated raw muslin fabric is found to be a promising and affordable alternative to surgical masks.
