Summary: Mesoporous silica material of MCM-41 type with spherical morphology was modified with copper, iron, or manganese as well as combinations of these metals. The modified samples were characterized for their structure, morphology, surface acidity, transition metal loadings, and reducibility. The catalytic performance of monometallic and bimetallic samples in the selective catalytic reduction of NO with ammonia was tested, and the bimetallic copper-manganese sample showed the best catalytic activity. The synergistic cooperation between manganese and copper species may be attributed to charge relocation, resulting in improved activation of the catalyst for the desired reaction.

Summary: The copper-modified catalyst with aluminum containing silica spherical MCM-41 was synthesized using the template ion-exchange method and directly treated with ammonia solution. The highly dispersed monomeric Cu2+ cations, deposited on the surface, showed significantly better catalytic effectiveness in the NH3-SCR process compared to aggregated copper oxide species. The catalyst obtained by the TIE-NH3 method operated effectively in a broader temperature range and had lower activity in the side process of direct ammonia oxidation.

Summary: Different amounts of BiOBr and g-C3N4 were loaded on MCM-41 to achieve efficient photo oxidation and adsorption of DBT. The optimal photocatalyst, BiOBr-C3N4/MCM-41 with 10% BiOBr, showed highest activity and lowest DBT concentration, attributed to the highest structural defects and strongest interaction. However, after four cycles, a decrease in activity was observed due to pores blockage by DBT sulfones.

Summary: In this paper, Ni/MCM-41 catalyst was prepared by chemical reduction method, and Nin@Pd1/M41 core-shell nanocatalysts were prepared by ultrasound-assisted galvanic replacement method. The results showed that Nin@Pd1/M41 had electron transfer and SMSI effect, promoting its catalytic performance. The dehydrogenation efficiency of H12-NEC reached 100% at 180°C for 4 h and at 170°C for 6 h, and 97.58% for 6 h at 160°C, with a TOF of 5080.6 h-1, which was better than that reported in the literature. The excellent catalytic performance of Ni6@Pd1/M41 can mainly be attributed to the synergistic effect of coordination and strain effects between the bimetals.

Summary: Co-doped Au-25 nanoclusters with different numbers of doping atoms were synthesized and supported on CeO2 for catalytic CO oxidation. The catalytic activity was enhanced compared to pure Au-25 nanoclusters, with different performance depending on the number of Co atoms. XAFS, DRIFTS, and XPS studies revealed the evolution of doped Au clusters into CoAu nanoalloys with well-distributed Co atoms. Understanding the dynamics of doped nanoclusters on supports is crucial for the future development and application of bimetallic nanocluster catalysts.

Summary: The catalytic behavior of Rh particles supported by different materials (Rh, Au, and ZrO2) in H-2 oxidation was investigated using photoemission electron microscopy (PEEM) and scanning photoemission electron microscopy (SPEM). Different catalytic performances were observed depending on the support and Rh particle size, with oscillations ranging from particle size-independent to fully inhibited. The experimental observations were supported by micro-kinetic simulations, which revealed the importance of hydrogen adsorption and oxygen binding in the catalytic process. This study highlights the significance of correlative in situ surface microscopy in understanding the relationship between local structure, composition, and catalytic performance.

Summary: Chiral gold nanoclusters were synthesized using the chiral ligand 2-MeBuSH, leading to the unexpected formation of enantiopure chiral clusters. The chiral activity of Au-144 was found to be stronger than Au-38 or Au-25, as confirmed by experimental evaluation using circular dichroism spectroscopy. The prepared chiral clusters exhibited stability against diastereoisomerization up to temperatures of 80°C. These findings demonstrate the selective preparation of enantiopure, intrinsically chiral, and highly stable thiolate-protected Au nanoclusters, supporting the predicted super chirality in the Au-144 cluster.

Summary: CuO/CeO2 nanosphere catalysts were synthesized and tested for CO oxidation and preferential oxidation of CO (PROX) in excess H-2. The catalytic performance was independent of the initial oxidation state of the catalyst (CuO vs. Cu-0), suggesting the formation of the same active phase under reaction conditions. Density functional modeling was applied to understand the intermediate steps of CO oxidation and H-2 transformation.

Summary: This study investigated the direct conversion of methane (CH4) to value-added hydrocarbons (C2+) using a hybrid catalyst. The hybrid catalyst consisted of Ni/Al2O3 as the first catalyst layer to convert CH4 to carbon monoxide and K-Co/Al2O3 as the second catalyst layer to convert carbon monoxide to C2+. The hybrid catalyst exhibited effective performance at a relatively low temperature of 490 degrees C, compared to other catalysts used in methane oxidative coupling reactions. The study explored the effects of different operating conditions and found that the highest C2+ yield of 4.3% was achieved at a reactor temperature of 490 degrees C. The addition of K promoter played a crucial role in enhancing C2+ formation. The proposed mechanism for the reaction using the hybrid catalyst was described, and the stability of the catalyst was observed to be excellent during a 24-hour time-on-stream test.

Summary: Promoters play an important role in catalysis, but their function and role in reaction instabilities are often unknown. This study demonstrates the local catalytic effect of La in hydrogen oxidation reaction using Rh nanotip as a mimic of single Rh nanoparticle. The presence of La shifts the reaction states, changes the oscillation pattern, and deactivates one of the pacemaker types. The effect originates from the enhanced oxygen activation on the catalyst.

The results showed that the chemical modification increased the fraction of micropores, specific surface area, and changed the surface properties of biochar. The experiment also revealed that biochar pretreated with alkali exhibited the maximum adsorption capacity for copper ions. A conceptual model identifying the mechanisms of copper adsorption on sapropel-based biosorbent was proposed.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
