Summary: Iron-tungsten composite oxide catalysts were prepared using a no-water grinding method followed by calcination at different temperatures. The study found that catalysts prepared at low temperatures showed the greatest catalytic activity, while high-temperature calcination led to decreased catalytic properties. Additionally, catalysts calcined at 500 degrees Celsius exhibited the best catalytic performance due to the coexistence of surface defects and specific species, resulting in over 90% NOx conversion in the 220-500 degrees Celsius range.

Summary: Active components play different roles in improving catalytic performance due to their different physicochemical properties. In this study, a series of SmCeMn/Ti catalysts with different metal components exposed on the outer surface were synthesized to study their catalytic roles for NH3-SCR. The results showed that Mn contributed more B-acid sites and Mn4+, facilitating NO conversion. Ce generated a large amount of Mn4+ through a strong redox reaction with Mn3+ and generated abundant oxygen vacancies during the reaction process due to its strong oxygen storage-release capacity, while Sm acted as a sacrifice site for electron transfer with Mn to improve sulfur resistance.

Summary: In this study, operando spectroscopies were used to investigate the selective catalytic reduction of NO with NH3 over WO(3)-loaded CeO2. The reduction/oxidation half-cycles were elucidated through in situ Ce and W L-3-edge X-ray absorption near-edge structure, UV-vis, and infrared spectroscopies. The Ce4+ species were reduced by NO + NH3 to yield N-2 and Ce3+ species in the reduction half-cycle, which were then reoxidized by O-2 in the oxidation half-cycle. The oxidation state of the W(6+) species remained unchanged under redox conditions. IR and theoretical results suggested that the reduction half-cycle started with the reaction of W6+-OH and adjacent Ce(4+)-O with NO to afford Ce3+ species and gaseous HONO, which was then converted to NO+ species on the catalyst. The NO+ species reacted with NH3 to generate N-2.

Summary: The study involves the preparation and characterization of copper-loaded eta-alumina catalysts with different copper contents for catalytic reactions. Experimental results indicate that the impregnation/evaporation method is beneficial for highly dispersed copper oxide species on the surface at low copper contents. Wet impregnation allows for a well dispersion of copper species on the alumina surface for low copper contents, leading to similar catalytic performance in the selective catalytic oxidation of NH3.

Summary: The study found that partial substitution of zirconium for praseodymium in a ceria-zirconia support can enhance the support reducibility, but impregnation of niobium and tungsten inhibits the redox behaviors. Additionally, niobium and tungsten provide acidic sites while praseodymium inhibits ammonia storage and decreases deNO(x) performances. The various redox and acidic behaviors observed in the studied materials demonstrate a strong competition between NOx SCR and NH3 oxidation pathways.

Summary: A flower-like 0.1%WO3/CeO2 catalyst was fabricated with high-efficiency for the selective reduction of NOx by NH3. The flower-like structure promoted a more uniform dispersion of tungsten species on the support and a stronger interaction between WO3 and CeO2, resulting in increased acid sites and surface vacancies. The catalyst exhibited significant SCR performance, with 90% NOx conversion and 95% N2 selectivity within a wide temperature range. The study provides a new strategy for developing high-efficiency ceria supported NH3-SCR catalyst.

Summary: New carbonized biomass-metakaolin (PSD/MK_Fe) granular composite catalyst materials were successfully manufactured for the catalytic wet air oxidation (CWAO) of bisphenol A (BPA). The catalysts showed high efficiency in achieving nearly complete BPA conversion (>98%) and total organic carbon (TOC) conversion of 70% under optimal conditions. The enhanced catalytic activity was attributed to the high specific surface area of the catalysts, along with the surface acidity playing a role in affecting the catalytic activity.

Summary: In this study, the CO2 activation behavior of doped ceria-based metal oxides and the influence of chemical and mechanical strain were investigated using experimental and ab initio modeling approaches. The results showed that mechanical strain increased the CO2 adsorption sites but reduced their thermal stability. Ab initio calculations revealed that doping and tensile strain could enhance CO2 adsorption. Additionally, ball milling of the oxides improved the reducibility of the catalysts and increased the conversion of CH4 and CO2 in a catalytic reaction.
