Summary: A series of MnCo/Cu-Z catalysts with different Mn/Co ratios were prepared and investigated for the SCR of NO with NH3. The Mn1Co2/Cu-Z catalyst showed the highest activity, with high-valent metal ion enrichment and improved metal oxide reducibility contributing to its enhanced catalytic performance.

Summary: A comprehensive microkinetic model was established for NO oxidation, standard SCR and fast SCR on CeWOx at low temperatures, revealing different rate-limiting steps and reaction orders for different reactions. The mechanisms of standard and fast SCR were found to be similar, with the reaction between nitrites and adsorbed NH3 playing a key role in NOx conversion. The activation energy of fast SCR was higher due to the reaction between NO and NH4NO3, but more nitrites and NH4NO3 led to higher activity for fast SCR compared to standard SCR.

Summary: A series of Mn-Fe mixed oxides doped with CeO2, Al2O3, and Sm2O3 were prepared and used as catalysts for NH3-SCR of marine diesel exhausts. The co-doped Mn-Fe oxide catalyst showed the best deNOx activity and SO2 tolerance. The addition of Ce promoted the formation of Mn-Fe solid solutions, while Al enhanced the dispersion of different elements in the catalysts. The introduction of Ce, Al, and Sm species adjusted the reduction properties, increased surface acidity sites, and improved catalytic activity.

Summary: This study investigates the poisoning effect of SO2 on binary MnTi and ternary MnCeTi mixed oxides for the NH3-SCR reaction. The addition of Ce widens the optimal operational temperature range, but the presence of SO2 drastically decreases catalytic activity in all catalyst samples. Further characterization reveals adsorption and poisoning of SO2 on the catalysts, and doping studies do not provide effective solutions to suppress SO2 deactivation.

Summary: M/ZSM-5 (M = Mn, Co, Cu) samples were prepared by impregnation and their catalytic performance in NH3-SCR of NO was tested. Cu/ZSM-5 exhibited the highest activity, followed by Mn/ZSM-5, and Co/ZSM-5 was the least active. In-situ DRIFTS analysis revealed the nature and evolution of surface species. Coordinated NH3, NH4+, and amide (-NH2) species derived from NH3 adsorption were found to be relevant for NH3-SCR, while bridged nitrate species derived from NOx adsorption were identified as the main active species. Bridged nitrate was more abundant and thermally more stable on Cu/ZSM-5, consistent with its higher activity compared to Mn/ZSM-5 and Co/ZSM-5. Different mechanisms, including Eley-Rideal and Langmuir-Hinshelwood, were observed for Mn/ZSM-5 at different temperatures, while both pathways coexisted for Co/ZSM-5 and Cu/ZSM-5.

Summary: The design of supportive atomic sites with a controllably adjusted coordinating environment is crucial for advancing CO2 reduction and achieving carbon neutralization. In this study, atomic Ni (Zn) sites coordinated with ternary Zn (Ni)/N/O ligands were successfully decorated on formamide-derived porous carbon nanomaterials. The decorated NiZn-NC exhibited high CO Faraday efficiency and significantly decreased desorption of molecular CO, attributed to the unique atomic structure of Ni(N2O1)-Zn(N2O1) and the modulation of electronic structure by N/O dual coordination.

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.
