Removal of hydroxyl groups and its influence on the microstructures evolution of alumina-mullite fibers fabricated by sol-gel process

Qiang Liu et al.

Summary: The removal of hydroxyl groups and its effect on phase transition and microstructural evolution of alumina-mullite fibers were studied. The removal of hydroxyl groups occurred mainly before 800 degrees C. The mullitization temperature of fibers with high hydroxyl groups content was 1300 degrees C, while that of fibers with low hydroxyl groups content was 700 degrees C. An appropriate amount of residual hydroxyl groups was beneficial for obtaining a dense fine-grained microstructure of the fibers after sintering, with an increased tensile strength of 1.6 +/- 0.22 GPa.

Yang-wen Wu et al.

Summary: By modifying a commercial SCR catalyst with FeO x , the synergistic removal activities for NO and dioxins were improved. The addition of FeO x increased the specific surface area and pore volume of the catalyst, improving the dispersion of vanadium species. The enhanced surface acid centers and redox capacity of the catalyst further increased the adsorption and destruction efficiencies of both nitric oxide and dioxins.

Development of low-carbon alkali-activated materials solely activated by flue gas residues (FGR) waste from incineration plants

Muhammad Riaz Ahmad et al.

Summary: Flue gas residues (FGR) from incineration plants were used as an alternative alkaline activator for producing low-carbon and cost-effective alkali-activated materials (AAMs), along with fly ash (FA) and slag as precursor materials. Microstructure analysis showed the formation of N-A-S-H gel, hybrid gel (C-N-A-S-H), and C-A-S-H gel as the main reaction products. The content of FGR directly influenced the formation of C-A-S-H gel. In the presence of Na2SO4, the volume of Ca-based reaction products (C-N-A-S-H and C-A-S-H) increased due to the activation of slag. The compressive strength of AAMs was in line with the microstructure analysis results. XRD analysis identified the formation of zeolite, apatite, and berlinite as new reaction products. Leaching concentrations of heavy metals in FGR were below the regulatory limits, classifying it as a non-hazardous material.

Efficient degradation of multiple Cl-VOCs by catalytic ozonation over MnOx catalysts with different supports

Fawei Lin et al.

Summary: This study investigated the catalytic ozonation of different Cl-VOCs over supported MnOx catalysts and found that the catalytic performance and byproducts formation varied among different Cl-VOCs. Among all the Cl-VOCs, Mn/HZSM-5(27) showed better conversion and mineralization rate, and the catalytic co-ozonation of mixed Cl-VOCs exhibited both inhibitive and promotive effects. Competitive adsorption and the difficulty of Cl-VOCs degradation were the determining factors in catalytic co-ozonation, while the presence of H2O had negligible impact. These findings provide valuable references for industrial applications involving multiple Cl-VOCs and water vapor.

Catalytic feasibility of Ce-doped LaCoO3 systems for chlorobenzene oxidation: An analysis of synthesis method

Hector Acosta Perez et al.

Summary: Ce-doped LaCoO3 perovskites show promising catalytic performance for the elimination of Cl-VOCs. The insertion of Ce in the perovskite structure promotes the formation of Co2+/Co3+ and Ce3+/Ce4+ redox pairs and oxygen vacancies, leading to enhanced catalytic activity. Ce-doped LaCoO3 samples prepared by reactive grinding exhibit comparable performance to those synthesized by the citrate method, demonstrating the feasibility of this green chemistry alternative. The stability of the samples under total combustion reaction conditions is excellent, with sustained activity for 45 hours.

Summary: This study focuses on the influence of TiO2 surface chemistries on properties of formed vanadium species during a thermal activation. The results show that TiO2 with more Ti4+ tends to be reductive, while TiO2 with more Ti3+ tends to be oxidative. In the catalytic oxidization of chlorobenzene, the Ti4+-induced catalyst shows a much higher conversion rate compared to the Ti3+-induced catalyst.
