The combustion reaction, carried out at 450°C with AgNO₃ and (NH₄)₂[Ce (NO₃)₆] as metal precursors, produced CeO₂ and Ag/CeO₂ NPs. Their structure and morphology were estimated by P-XRD and TEM, which confirmed the formation of cerianite with cubic fluorite CeO₂ crystal structure, while SEM revealed a porous morphology characteristic of combustion-driven gas evolution. EDS revealed the presence of Ce, O, and Ag in the Ag/CeO₂ NPs. Optical studies, including UV–Vis and PL, showed that Ag incorporation narrowed the band gap and improved charge-carrier separation, contributing to enhanced visible-light activity. XPS analysis verified the successful incorporation of Ag species into the CeO₂ lattice. Among the investigated NPs, the 0.3 wt% Ag/CeO₂ sample exhibited the lowest PL intensity, indicating improved charge-carrier separation, which was further supported by its high quantum yield (0.789). These results correlate with its enhanced photocatalytic activity. The nanomaterials were evaluated for dye degradation, Cr (VI) reduction, photocatalytic H₂ evolution, and antibacterial activity. The influences of pH, catalyst dosage, dye concentration, light intensity, radical scavengers, and recyclability were also systematically assessed.

In this case, discrimination between the plausible kinetic models is required. An intrinsic kinetic model of a heterogeneous catalytic process may successively be discriminated by the transition from a reaction rate-limited regime to an intraparticle diffusion-limited regime. The effectiveness factor for competing kinetic models sometimes follows notably different trends versus reactant concentration. Therefore, taking the effectiveness factor into account provides one with an instrument for the selection of the most realistic kinetic model. The proof of concept is demonstrated using exemplary kinetics of the methanol dehydration over a commercially available activated <i>γ</i>-alumina catalyst. Methanol dehydration is an important commercial process since it produces a valuable chemical, which is dimethyl ether. It has been shown previously that this process follows the Langmuir–Hinshelwood kinetics with either dissociative or associative methanol adsorption. With the utilization of the intraparticle diffusion approach, it is demonstrated that only a dissociative path is appropriate. The problem of the experimental evaluation of the effectiveness factor and the limitations of the approach are also discussed.</p>","PeriodicalId":49237,"journal":{"name":"Asia-Pacific Journal of Chemical Engineering","volume":"21 4","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/apj.70247","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148662792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analysis focuses on systems representative of typical pipeline operating conditions (80–200 bar) containing water, monoethylene glycol (MEG), and lower concentrations of sodium chloride, which are commonly encountered inhibitors in natural gas transmission systems. Differences in thermodynamic models and equations of state were examined to assess their ability to capture the combined inhibitory effects of MEG and dissolved salts. The results demonstrate that all investigated software packages overpredict hydrate dissociation temperatures in the presence of salts, indicating that the full inhibitory effect of salts is not adequately represented. For salt-free systems, Aspen HYSYS with the glycol fluid package provided the most reliable predictions, whereas Multiflash using the Peng–Robinson equation of state yielded the closest agreement with experimental data for salt-containing mixtures. However, even this model underestimates salt inhibition. The low salt concentration range (1–3 wt%) was found to exhibit the largest model inaccuracies. An adjustment-factor analysis suggested that the salt inhibition is underestimated by a factor of 3–4 in commonly used software models for very low (~1 wt%) concentrations.

The mathematical model incorporates magnetic field effects, solar radiation, unsteadiness, and viscosity variations at limiting shear rates. The governing nonlinear partial differential equations are transformed into dimensionless form of ODEs and then solved numerically using the Chebyshev collocation method implemented in Mathematica 11.3. The results reveal that increasing the magnetic parameter significantly suppresses fluid velocity due to enhanced Lorentz forces, while thermal radiation intensifies the temperature distribution within the boundary layer. The wedge angle and velocity ratio parameters substantially influence shear stress and thermal boundary layer thickness. Furthermore, ternary hybrid nanofluids demonstrate superior thermal performance compared to conventional hybrid nanofluids under identical conditions.
