Summary: Single-atom catalysis is a hot topic in heterogeneous catalysis, but determining the stability and activity of single atoms on oxide supports compared to clusters and nanoparticles remains challenging. It was found that single Au atoms at step-edges serve as active sites for low-temperature CO oxidation, and the interface between Au nanoparticles and CeO2 can directly catalyze CO oxidation through the Mars-van Krevelen mechanism.

Summary: MXenes have garnered significant attention for their versatile and excellent physicochemical properties, particularly for their potential applications as robust supports for single-atom catalysts. In this study, quantum chemical investigations using density functional theory were conducted to systematically examine the geometries, stability, and electronic properties of oxygen-functionalized Ti2C (Ti2CO2)-supported single-atom catalysts M-1/Ti2CO2 (M = Fe, Co, Ni, Cu, Ru, Rh, Pd, Ag, Os, Ir, Pt, Au). Among the transition metals in groups 8-11, a new non-noble metal single-atom catalyst Fe-1/Ti2CO2 was found to exhibit excellent catalytic performance for low-temperature CO oxidation. Detailed analysis revealed that O-2 and CO adsorption on the Fe-1 atom of Fe-1/Ti2CO2 is favorable. Furthermore, five possible mechanisms for CO oxidation on this catalyst, including Eley-Rideal, Langmuir-Hinshelwood, Mars-van Krevelen, Termolecular Eley-Rideal, and Termolecular Langmuir-Hinshelwood (TLH) mechanisms, were evaluated. Based on the calculated reaction energies for different pathways, it was observed that Fe-1/Ti2CO2 demonstrates excellent kinetics for CO oxidation via the TLH mechanism, featuring a significantly low energy barrier (0.20 eV) for the rate-determining step. These findings establish Fe-1/Ti2CO2 MXene as a highly promising 2D material for constructing robust non-noble metal catalysts.

Summary: A novel polymerization-sulfurization-pyrolysis strategy was used to construct N,S co-doped carbon to anchor Co single atom (Co-SAs) catalysts for the selective electro-oxidation of thioethers in acidic solution. The as-obtained Co-SAs showed excellent electrocatalytic activity and stability, outperforming commercial Pt electrode and state-of-the-art catalysts. The high performance of Co-SAs was attributed to the Co-S2N4 coordination geometry, which significantly promoted desorption of the products.

Summary: This study systematically investigates the CO oxidation processes on a CuAu alloy monolayer supported on tungsten carbide, and compares it with pure metal monolayers using first-principles calculations. The introduction of Cu dopant in the Au monolayer enhances the adsorption of reactants, which lowers the energy barriers for the formation and dissociation of the intermediate OOCO. The rate determining step is identified as the oxidation of CO by an atomic O, with an energy barrier superior or comparable to reported CO oxidation catalysts. This work highlights the significance of alloy monolayers on tungsten carbides for the rational design of highly efficient catalysts.

Summary: Currently, MXenes have been recognized as a promising choice for Na-ion battery electrode materials due to their excellent energy storage and electrical conductivity. Among these, dual transition metal MXenes have gained attention as anode materials for Na-ion batteries because of their superior properties. In this study, we compared the performance of TiNbC-based dual transition metal MXenes and Nb2C-based single transition metal MXenes as anode materials for Na-ion batteries through density functional theory calculations. The results showed that TiNbC, TiNbCO2, Nb2C, and Nb2CO2 exhibited great potential as anode materials due to their low diffusion barrier and high Na capacity. Furthermore, TiNbC-based MXenes demonstrated better adsorption performance, diffusion rate, and theoretical storage of Na atoms compared to Nb2C-based MXenes, which was attributed to the synergistic effect between Ti and Nb. This discovery provides valuable insight for the development of high-performance MXenes-based anode materials for Na-ion batteries.
