Summary: MnOx-based oxides are efficient catalysts for elemental mercury oxidation in flue gas, and combining with CeO2 or CeO2-ZrO2 enhances their catalytic activity. The new MnOx-CeO2-ZrO2 solid solution catalyst showed better Hg-0 oxidation performance compared to the MnOx/CeO2-ZrO2 supported catalyst. Mn4+ and surface active oxygen were identified as the active species in Hg-0 oxidation reactions, and SO2 significantly inhibited the activity of MnOx/CeO2-ZrO2 but had less impact on MnOx-CeO2-ZrO2 solid solution.

Summary: A series of Mn-doped CeO2-MoO3/gamma-Al2O3 catalysts were synthesized and it was found that the addition of Mn significantly improved the performance of the catalysts, with the best Hg-0 catalytic oxidation efficiency reaching 86%. The addition of Mn increased the concentration of oxygen vacancies on the catalyst surface, promoting the catalytic oxidation of mercury.

Summary: In this study, CeO2 @TiO2 catalysts were prepared by encapsulating Ce ions into MIL-125 channels and annealing the Ce/MIL-125 precursor. The CeO2 @TiO2 catalysts had a NO conversion of nearly 100% at 350 degrees C and a wide temperature range larger than 200 degrees C, attributed to the high dispersion of CeO2 in the composites and the porous structure of CeO2 @TiO2 (2/3) catalyst, which exhibited high specific surface area. Furthermore, the CeO2 @TiO2 (2/3) catalyst had excellent NH3-SCR properties with a wide temperature range (200 degrees C to 450 degrees C) and outstanding resistance to H2O and SO2, thanks to the presence of Ce3+ sites, enriched surface oxygen species, effective adsorption of NOx species, and high surface acidity.

Summary: This study examined the effects of different supports on the activity and selectivity of nickel phosphide catalysts in anisole hydrodeoxygenation. Ni2P/CeO2 showed the highest activity among the synthesized supports and common materials. Ni2P/TiO2-CeO2 exhibited superior reactivity and higher cyclohexane selectivity compared to Ni2P/CeO2. The choice of support also influenced the product distributions and HDO pathways. Both Ni2P/CeO2 and Ni2P/TiO2-CeO2 are promising catalysts for tunable production of benzene and cyclohexane, respectively.

Summary: A simple hydrothermal method is used to dope cobalt species into CeO2 nanorods, which improves the reduction properties and activity of CeO2 for Hg-0 removal. Co doping increases the adsorption energy of Hg-0 and promotes the formation of oxygen vacancies, leading to enhanced activity for Hg degrees removal. The oxidation of Hg-0 over Co-doped CeO2 nanorods occurs through a Mars-van Krevelen mechanism, where Hg-0 reacts with surface oxygen to form HgO.

Summary: This paper investigates the resistance of MnOx-CeO2/TiO2 catalyst to SO2 and H2O, and discusses their poisoning mechanism based on catalytic characterizations. The results show that the catalyst exhibits high tolerance to SO2 poisoning due to the preferential formation of surface sulfates on Ce dopants, which protect the main active component. However, the presence of both SO2 and H2O leads to more severe catalytic deactivation, indicating their synergistic toxicity in poisoning the catalyst.

Summary: This paper reviews methods for recovering different forms of phosphorus from solid products obtained from different sludge thermal treatment methods, as well as the bioavailability of the recovered phosphorus products. Incineration of sewage sludge is currently the most established and effective method for recovering phosphorus, while one wet chemical method has been commercialized and is expected to be further developed for industrial applications in the future. Pyrolysis and hydrothermal carbonization still have research gaps, but both have the potential to recover phosphorus and should be further explored based on their principles and laboratory performance.

Summary: This study conducted co-hydrothermal carbonization of rape straw and microalgae to obtain clean hydrochar. The effect of different feedwater pH values on co-HTC and the mechanism of enhanced N, S, and O removal were revealed. Acidic and alkaline conditions in the feedwater exacerbated the carbonization process. The hydrochar formed under acidic conditions had a higher heating value and deamination and deoxidation were the main methods for protein degradation and N, S, and O removal. The results provide insights into the production of hydrochar with improved properties.

Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
