Furthermore, the work estimates the variations in Young’s Modulus and dielectric constant of the composites with varying concentration of NiO in the composites. The nanocomposites were synthesized via an in-situ polymerization method, incorporating varying weight percentages of NiO nanoparticles into the Polyaniline matrix. The UV-Vis spectroscopy was conducted to probe the bandgap energy of the nanocomposites, revealed the π-π* transitions associated with the conjugated structure of polyaniline. PL spectra showed a red shift in wavelength with the addition of NiO nanoparticles, indicating increased conjugation length of PANI and altered energy states due to interactions with NiO. FESEM analysis revealed the consistent and even dispersion of NiO nanoparticles within the PANI matrix. EDS analysis indicates a corelation between the nickel weight% and increasing NiO concentration. Moreover, mechanical characterization through Young’s Modulus measurements indicated negligible modifications in stiffness of the composites. The dielectric constant increases with the addition of NiO, likely due to induced polarisation in the composites. Overall, the findings suggest that the incorporation of NiO nanoparticles into polyaniline enhances its conductivity and dielectric properties.</p></div>","PeriodicalId":801,"journal":{"name":"Topics in Catalysis","volume":"69 4-7","pages":"740 - 750"},"PeriodicalIF":3.0,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147337813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The gas composition included 3% (v/v) O₂ and 6% (v/v) H₂O at GHSV = 70,651 h⁻¹. There are two NO conversion zones as a function of temperature, previously reported. The low temperature ranged from 60 to 180 °C and reached 100% conversion of NO to N₂ at 140 °C. The addition of C₃H₈ had a small effect, decreasing NO conversion to 90–95%, and the temperature window about 10 °C. The H₂ conversion increased as a sigmoidal curve with temperature in all cases, and it shifted to low temperature too. This NO reduction range corresponds to the H₂-SCR. The high temperature activity region involves competition for O₂ between NO and C₃H₈. When C/N = 0 there was only oxidation to NO₂.
