Summary: The study found that a specific iron phthalocyanine dimer catalyst can efficiently facilitate the hydroxylation of benzene under mild conditions in an acetonitrile solution with excess H2O2 present. Mechanistic studies indicated that the reaction was catalyzed by a high-valent iron-oxo species generated in situ, and the peripheral methyl groups of the catalyst may enhance the production rate of the iron-oxo species.

Summary: Efficient and selective oxidation of arene C-H bonds has long been a challenging goal. Here, we present a facile and practical strategy to fabricate an N-doped reduced graphene oxide (NRGO) based single-atom Cu catalyst (SACu-NRGO) for the selective oxidation of benzene to phenol at room temperature. The SACu-NRGO exhibits excellent catalytic performance with a selectivity of 98.6% towards phenol, thanks to the fully exposed and homogeneously dispersed CuN3 active sites anchored by adjacent pyrrolic N atoms in the NRGO skeleton. Furthermore, the structure of the single-atom active sites and the mechanism of the oxidation process are elucidated in depth through DFT calculations.

Summary: The study attempted to determine the metal location and estimate the site occupancy in zeolite through Cs-corrected STEM imaging of La-exchanged NaY zeolite. It was found that La atoms were located at sites I and I' with an estimated occupancy of about a fourth for both sites. The imaging also revealed that the La occupancy at site I was much larger than measured by XRD, possibly due to the highly dehydrated state of LaNaY.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

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.
