Summary: Efforts have been made to explore the effective composite catalysts for low-temperature selective catalytic reduction of NOx by CO (CO-SCR), using Fe-Cu bimetal oxide as the active component and various supports. The results show that Fe2Cu1/ amorphous SiO2 catalysts exhibit the best catalytic performance, with high conversion ratios and good resistance to O2, SO2, and H2O. The excellent SCR performance is attributed to the specific properties of amorphous SiO2, such as large surface area, good structural stability, and uniform distribution of active sites. This research provides insights for the improvement of industrial applications and the development of non-ammonia SCR technology with near-zero emissions.

Summary: Cu and Fe modifications on activated carbon were investigated to improve the activity and sulfur resistance for the reduction of NO by CO in regeneration gas. Different metal sites showed different activities at different temperatures, and DFT calculations proved that binding Cu2+ and Fe3+ sites have higher activity than free Cu2+ and Fe3+ sites. Additionally, AC-Fe-H exhibited excellent resistance and stability against SO2 and H2O.

Summary: Oil shale semi-coke (OSS) is a byproduct of oil shale pyrolysis, and its large-scale production causes severe environmental pollution. This study explores the sustainable and effective utilization of OSS by preparing activated carbon using microwave-assisted separation and chemical activation. The results show that activated carbon prepared with FeCl3-ZnCl2/carbon precursor has superior properties compared to other activation methods. The electrochemical evaluation also demonstrates the potential of using this activated carbon in high-performance supercapacitors.

Summary: In this paper, the authors study the factors of nitrogen doping, iron doping, and CO introduction as catalyst carriers for NOx removal. The research analyzes the NO heterogeneous reduction using DFT calculation method and quantitatively analyzes reaction kinetics using the transition state theory. The results show that nitrogen doping improves NO removal rate, iron doping enhances the adsorption capacity of carbon active sites, and CO introduction promotes the production of N2, CO2, and N2O.

Summary: Supported nickel oxides are widely studied as oxygen carrier materials for chemical looping combustion and reforming of methane due to their high activity for methane conversion. However, coke formation remains a challenge for Ni-containing oxygen carriers. This study investigates the use of reducible, spinel-structured supports to enhance the coke resistance of NiO-based oxygen carriers.

Summary: A novel Fe(II) activated-Fenton sludge (FS-FeSO4) was proposed for stabilizing arsenic (As) and antimony (Sb) co-contaminated soil while disposing FS. Multiple characteristic analyses revealed that FS-FeSO4's porous structures and rich functional groups were involved in As and Sb adsorption. Meanwhile, Fe (hydro)oxides played a key role in As and Sb stabilization.

Summary: The study investigates the impact of Fe/Co co-substitution on the multiferroic properties of BSmT, revealing ferromagnetic and ferroelectric behavior at room temperature, with the sample at x = 0.4 exhibiting the highest magnetization values. The interaction between oxygen vacancies and magnetic ions contributes to the occurrence of magnetism, while the reversible polarization induced by an electric field demonstrates the ferroelectric nature of the ceramics.

Summary: Perovskite oxides, specifically LaFe1-xCoxO3, were synthesized through hydroxycarbonate precursor co-precipitation and thermal decomposition. The addition of 5% cobalt led to a significant increase in catalytic activity, with higher cobalt loadings showing a non-linear trend in activity. This enhanced activity was likely due to improved redox properties and reduced surface deactivation related to carbonate poisoning.
