Titanium dioxide (TiO₂) has been extensively studied for this reaction due to its high activity and low cost. However, the inherent heterogeneity of commercially available TiO₂ has led to conflicting reports on reactivity and product selectivity, further complicated by the diverse reaction conditions employed in previous studies. This work aims to update our understanding of alkanol reactions on anatase TiO₂ by integrating transient, titration, kinetic, and spectroscopic methods, using 2-propanol and 1-propanol as model reactants. Under anerobic conditions, 2-propanol primarily undergoes dehydration to form propene and water. A minor pathway forms acetone via nonoxidative dehydrogenation, but only after an induction period during which surface oxygen vacancies accumulate. Notably, propene formation rates remain largely constant, even as acetone formation rates decrease by ∼60 % during the initial induction period. These transient behaviors, together with pretreatment and characterization data, suggest that dehydration predominantly occurs on smaller TiO₂ crystallites that provide most of the surface area, whereas dehydrogenation is favored on larger crystallites with smaller band gap energies. In situ pyridine titration was used to quantify the number of active sites for each pathway, enabling accurate turnover rate normalization. Detailed kinetic analysis showed that both dehydration and nonoxidative dehydrogenation are inhibited by 2-propanol, water, and 2-propanol–water dimers, but to different extents. The rate constant for nonoxidative dehydrogenation reflects a significantly lower activation enthalpy than that for the oxidative route; however, this is offset by a large entropic penalty, resulting in higher free energy barriers at relevant temperatures and thus a lower overall rate constant. This kinetic framework offers mechanistic insight into the temperature- and pressure-dependent shifts in reaction rates and product selectivity, while also reconciling prior discrepancies reported in the literature.</div></div>","PeriodicalId":346,"journal":{"name":"Journal of Catalysis","volume":"452 ","pages":"Article 116414"},"PeriodicalIF":6.5,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145043680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, structure-dependent multiscale modeling is required to accurately capture the interaction of CO₂ with the various Ni facets and to provide accurate atomistic insights. While mean-field multiscale models can be constructed for multifaceted nanoparticles, surface diffusion of adsorbates between the facets is often not considered. In this study, we close the gap by extending the open-source Cantera toolkit with a universal framework for surface diffusion between facets in mean-field microkinetic models, making it the first widely adopted software tool that includes these features. We leverage these updates to develop a thermodynamically consistent microkinetic model for a Ni nanoparticle consisting of Ni(111), Ni(100), Ni(211), and Ni(110) using data from DFT calculations and single-crystal experiments to unravel the interaction of CO₂ with these facets through the simulation of temperature-programmed desorption profiles. Including surface diffusion and coverage effects into the mean-field microkinetic model leads to a significantly improved agreement between experiments from a <figure><img></figure> catalyst and the simulations. Through rigorous correlated uncertainty quantification of all structural and energetic parameters, we are able to identify a microkinetic model within the uncertainty space that is in excellent agreement with the recorded desorption profile. This model highlights that Ni(110), which contributes only to a small extent to the overall Ni surface area, dominates the desorption pattern and that surface diffusion plays a crucial role.

Herein, we systematically investigate the role of crystal facet engineering on modulating the performance of copper-based catalysts, which achieves selective ECR for C₂ products through the regulation of key intermediate adsorption configurations. Density functional theory (DFT) calculations, combined with various characterization methods, indicate that the exposure of specific crystal facets on the copper surface plays a critical role in determining the selectivity of the products.
