The removal of soot particles via high-performance catalysts is a critical area research due to the growing concern regarding air pollution. Among various potential suitable for oxidation, cerium oxide-based materials have shown considerable promise. In this study, CeO2 samples obtained using range preparation methods (including hydrothermal synthesis (HT), sonochemical (SC), and hard template (TS)) were tested in combustion. They compared commercially available material (COM). All synthesized ceria thoroughly characterized XRD, RS, UV/Vis-DR, XPS, H2-TPR, SEM, TEM techniques. As confirmed current every sample can be used as an effective oxidation catalyst, with temperature 50% conversion not exceeding 400 °C tight contact mode. A strong correlation was observed between catalysts' Ce3+ concentration activity, higher levels leading improved performance. These findings underscore importance optimizing ceria-based environmental applications.

Abstract The shape and structure engineering of metal oxide nanomaterials are the potential strategies to optimize surface‐active sites with tunable selectivity for heterogeneous catalysis. This work reports synthesis two types nanostructured CeO 2 –Nb O 5 catalysts: (i) one‐pot hydrothermal (CeNb ‐HTS, HTS stands synthesis) (ii) impregnation on hydrothermally synthesized Nb nanorods ‐WI, WI wet‐impregnation) elucidate role particle addition in structure–activity efficacy nanocatalyst selective oxidative C–N coupling benzyl alcohol aniline produce N ‐benzylideneaniline (NBA). characterization studies showed nanorod morphology high dispersion CeNb ‐WI catalyst strong acidic more oxygen vacancies. Consequently, a significantly enhanced catalytic activity was achieved 96% yield NBA, whereas 62% conversion 92% NBA obtained pure nanorods. In contrast, ‐HTS gave 37% only. versatile efficiency is showcased by synthesizing various functional products. can be recycled 4 times without much variation achieving reasonably good aniline.
