Summary: This study aims to design an efficient adsorbent for high-efficiency removal of elemental mercury (Hg0) from coal-fired power plant emissions. By co-implanting porous TiO2 with inorganic-organic dual functional sites (-SH and MnOx), the 2SH-MnOx/TiO2 adsorbent achieved a Hg0 removal efficiency of 90% at 175 degrees C and a high gas hourly space velocity (GHSV) of 120,000 h-1. The co-existence of -SH and MnOx was found to promote Hg0 adsorption and enhance the transfer of electrons from Hg0 to the adsorbent surface.

Summary: In this study, MnO2 hollow spherical adsorbents were synthesized and their physicochemical parameters and Hg-0 removal ability were investigated at different calcination temperatures. The results showed that the adsorbent calcined at 300 degrees C demonstrated the highest performance, with over 90% Hg-0 removal efficiency achieved at 200 degrees C. The presence of surface acid sites promoted the physisorption of Hg-0 and compensated for the weak oxidative ability, leading to superior Hg-0 capture capacity. The Mars-Maessen mechanism helped to understand the Hg-0 capture pathways over Mn300.

Summary: In this study, a strategy to improve the catalytic performance of Pt-Sn alloy catalysts in ethane dehydrogenation (EDH) is proposed by engineering the shell surface structure and thickness. Density functional theory (DFT) calculations and kinetic Monte Carlo (kMC) simulations are used to understand the influences of catalyst surface structure, temperature, and reactant partial pressures. The results demonstrate that Pt@Pt3Sn catalysts generally have higher C2H4(g) activity and lower selectivity compared to Pt3Sn@Pt catalysts, due to their unique surface geometrical and electronic properties.

Summary: In this study, the inverse Mo6C4/Cu catalyst is modeled and predicted to promote C2 oxygenates formation in syngas transformation. The results show that the inverse Mo6C4/Cu catalyst greatly improves catalytic performance and facilitates C2 oxygenate production compared to previous catalysts. This is attributed to the synergistic effect between Mo6C4 cluster with Cu catalyst, which easily activates CO to produce CH2 monomer and facilitates CO insertion into CH2 to CH2CO.

Summary: An advanced oxidation process (AOPs) using Fe(II) activated peracetic acid (PAA) was investigated for the simultaneous removal of SO2 and NO from flue gas. The maximum removal efficiencies obtained were 92.3% for NO and 99.5% for SO2 under optimal conditions. Reactive oxidizing species and organic radicals were generated in the Fe(II)/PAA system, with organic radicals confirmed to be the major factors affecting NO oxidation. The main products of SO2 and NO removal were identified as SO42- and NO3-.

Summary: This study investigates the catalytic performance of a series of S-modified PdM IMCs with different M types (Cu, Ag and Au) and ratios (1: 1, 3: 1 and 1: 3) in C2H2 semi-hydrogenation using DFT calculations and microkinetic modeling. The results show that the catalytic performance strongly depends on the space region of metal active site and the electronic properties induced by S atoms and the M type and ratio. Only S/Pd1Ag1 and S/Pd1Au1 exhibit higher H2 dissociation activity, C2H4 selectivity and production activity, and can effectively inhibit the formation of green oil.

Summary: Activation and desorption of hydrogen in toluene methyl is the rate-limiting step for side-chain alkylation of toluene with methanol. In this study, two dehydrogenation strategies were employed to enhance catalytic performance by introducing Cu as a dehydrogenation component in PAl-NaX catalyst and adjusting the acid-base properties through varying NaOH loading. The relationship between the percentage of acid-base sites, low valence Cu species, and catalytic performance was investigated using various characterization techniques and ternary regression analysis. The results showed that Cu, especially low valence Cu species, promoted the selectivity of side-chain alkylation products to some extent, but base sites played a more critical role in enhancing selectivity.

Summary: Based on favorable thermodynamics and coking resistance, chemical looping oxidative dehydrogenation (CL-ODH) of ethane over IrO2 catalyst was studied. Two extreme states of the IrO2 surface structure, S-IrO2 and R-IrO2, were considered. It was found that the mechanisms of ethane dehydrogenation over S-IrO2 and R-IrO2 catalysts were different. The present study contributes to the understanding of ethane CL-ODH over metal oxide catalysts and provides valuable insights for process optimization and catalyst development.

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.
