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: A facile hydrothermal method was proposed to regulate the pore structure and introduce Ce-based Lewis sites within Ce-SBA-15, named as Ce-SBA-U. The mesoporous size of Ce-SBA-U could be enlarged by urea dosage, facilitating the mass transfer of ozone and its activation on Ce(III)-based Lewis sites. The Ce-SBA-U/O3 process achieved high removal rates of clofibric acid (CA) and TOC, indicating its superior performance compared to sole ozonation and Ce-SBA-15/O3 processes.

Summary: This study presents a simple method to synthesize e-PtNiCu NWs with high proportions of (110) and (100) facets, which exhibit remarkable performance in ethanol electrooxidation reaction. The improved performance of e-PtNiCu NWs is attributed to the synergistic catalytic effect between (110) and (100) facets. The thermodynamics and kinetic studies suggest that the synergistic effect of both facets can decrease the activation energy barrier and facilitate the charge transfer during the reaction.

Summary: In this study, an efficient NbCuCe oxide catalyst for reducing NOx emissions in cold-start diesel engines is reported. The catalyst exhibits higher DeNO(x) activity below 200 degrees C compared to the Cu-CHA zeolite catalyst, along with superior sulfur resistance, faster response, and lower NH3 slip. Atomically dispersed Cu species facilitate strong interaction between Cu and the Nb/Ce base catalyst, leading to improved low-temperature redox properties and NH3 adsorption/activation. The developed NbCuCe catalyst shows promising potential for efficient DeNO(x) in cold-start diesel engines and can be combined with Cu-CHA for a broader temperature range of operation.

Summary: Catalysts for Nb/CeSi2 with different loadings of niobium were synthesized and evaluated for NH3-SCR performance over a broad temperature range. The 20Nb/CeSi2 catalyst exhibited the best low-temperature NH3-SCR performance while maintaining excellent SO2/H2O resistance. The addition of niobium resulted in variations in the surface structure, specific surface area, and acidity of the catalyst, which facilitated the SCR reaction. The interaction between niobium and ceria was found to enhance the activation of inert surface nitrate, contributing to the improvement of the catalyst performance at low temperature.

Summary: A highly efficient Pt single-atom catalyst was constructed for the catalytic oxidation of C3H8 by calcination of Pt catalysts on pre-stabilized Ce0.9Zr0.1O2 support. The Pt single atoms with different strengths of Pt-CeO2 interaction and coordination environment were successfully achieved by controlling the calcination temperatures. The Pt/CZO-750 catalyst exhibited higher C3H8 oxidation activity than Pt/CZO-550, attributed to the higher concentration of surface Ce3+ species/oxygen vacancies and stronger Pt-CeO2 interaction.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
