Summary: The reaction between 6-DiPPon and [RuCl2(p-cymene)]2 resulted in the formation of two complexes with different ligands, the ratio of which can be controlled by the solvent used. In the presence of AgOTf and Na[BArF24], two other complexes were formed. The properties and reaction mechanisms of these new ligands and complexes have important implications for catalyst activity and applications.

Summary: Nano zero-valent iron loaded porous carbon derived from microplastics was designed as a heterogeneous catalyst for degradation of persistent organic pollutants. The catalyst exhibited high carbon yield and large surface area, leading to effective degradation of various pollutants. Hydroxyl radicals generated from the activation of H2O2 enhanced by zero-valent iron in Fe/MMPC were identified as the predominant species in the catalytic reactions.

Summary: Reactions of MH2 (M = Sr, Ba) with CO2 were investigated using matrix isolation infrared spectroscopy and quantum chemical calculations at 3.5 K. Isotopic substitutions and density functional theory (DFT) frequency calculations helped identify formate complex HM(eta(2)-O2CH) and formic acid complex (MH2)(HCOOH). The study also showed that transfer of hydride ions from a metal hydride to a CO2 moiety plays a crucial role in stabilizing these complexes.

Summary: In the study, it was found that cobalt catalysts are more active than nickel catalysts in the hydrolysis of sodium borohydride. One reason for the lower activity of nickel catalysts is the presence of hydrogen on its surface, which interferes with reactant adsorption. The addition of cobalt to nickel catalysts can enhance hydrogen generation rate.

Summary: Aqueous-phase catalyzed reduction of organic contaminants using zerovalent copper nanoparticles (nCu(0)) and borohydride has shown promising results. The study examined the effects of Cu-0/Cun+ ratio, surface poisoning, and regeneration of Cu-0 sites on the dechlorination of 1,2-dichloroethane (1,2-DCA). The results suggest that synthesis parameters and groundwater solutes influence the catalytic activity of nCu(0)-borohydride.

Summary: Wastewater detoxification and sulfate purification of flue gas desulfurization wastewater can be achieved by the simultaneous catalytic oxidation of SO32- and separation of Se using an oxygen-vacancy-enriched cobalt-ceria (OV-CoO/CeO2) bimetallic oxide. The catalyst showed a significantly increased oxidation rate of SO32- and high adsorption efficiency for Se. Characterization of the catalyst revealed the formation of cobalt oxide nanoclusters on the CeO2 matrix, which increased the catalytic activity. The Se adsorption behavior was well-predicted by a surface diffusion model.

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: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

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.
