Summary: The catalysts for synthesis of C2+ alcohols from CO2 hydrogenation face challenges regarding product selectivity and stability. Nitrogen-doped CuFeZn catalysts, prepared by calcination in a nitrogen atmosphere, exhibit good catalytic activity and stability. The optimized PDA/CFZ-N450 catalyst demonstrates a remarkable selectivity of 39.75% for C2+ alcohols and a stabilization period of 264 hours. The superior stability is attributed to the presence of doped nitrogen, which facilitates catalyst activity and stabilizes nitrogen species. However, sintering of active metals and migration of active species to the catalyst surface may lead to a decline in activity.

Summary: This research focuses on the direct formation of light olefins from CO2 hydrogenation. Bifunctional catalysts composed of zinc-based metal oxides and H-RUB-13 zeolite were prepared, and the selectivity of C2-4 olefins reached 64.7-83.2%. ZnZrOx/H-RUB-13 showed the highest CO2 conversion due to the presence of oxygen vacancies. Interestingly, propene and butene were the dominant hydrocarbons, indicating the potential of H-RUB-13 zeolite to suppress ethene formation. However, the distribution of light olefins also depended on the overall acidity of the bifunctional catalyst, with ZnCrOx/H-RUB-13 showing higher ethene selectivity.

Summary: Purposefully regulating the spatial distribution of acid sites in a zeolite catalyst can effectively enhance its performance in the conversion of methanol to olefins (MTO). The use of different sodium halides in the synthesis of ZSM-11 zeolites was found to influence the location and distribution of acid sites, which in turn affected the catalytic performance in MTO. The presence of Br- or I- anions in the synthesis gel led to a uniform distribution of Al species and improved catalytic stability and selectivity in MTO.

Summary: The conversion of CO and CO2 into valuable liquid fuels and chemicals through hydrogenation has attracted significant interest. This study evaluates the feasibility, limit, and suitable conditions for these reactions through thermodynamic considerations. Results show that the hydrogenation of CO/CO2 to alcohols, light olefins, and aromatics is thermodynamically viable under appropriate conditions. Although current conversion processes may be restricted by kinetic factors, it is important to ensure that the reactions are conducted under thermodynamically feasible conditions. These results help determine the suitable operation region for CO/CO2 hydrogenation and provide directions for optimizing catalysts and processes.

Summary: This study investigates the effects of acid density on the methanol-to-hydrocarbon (MTH) performances and deactivation behaviors of H-MCM-22 zeolites. It is found that acid density has a significant impact on MTH performances, while acid distribution has a smaller effect. Increasing acid density promotes hydrogen transfer reactions and the formation of aromatics, ethene, and alkanes. Low acid density results in coke covering acid sites inside the micropores, while high acid density leads to massive coke deposition on the external surface. The deactivation behaviors of H-MCM-22 zeolites can be divided into three stages.

Summary: This study demonstrates that modifying zinc-zirconium oxides with lanthanum can effectively promote the formation of methanol intermediates, leading to improved catalytic performance in CO2 hydrogenation to light olefins. The addition of lanthanum induces the formation of more oxygen vacancies on the surface of the catalyst, facilitating the adsorption and activation of CO2 and the generation of methanol intermediates. Coupling with acidic zeolites allows for the rapid conversion of the methanol intermediates into light olefins. The composite catalysts exhibit high selectivity for C-2(=)-C-4(=) hydrocarbons.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
