Summary: Supported bimetallic molybdenum and tungsten carbides can replace noble metal catalysts for renewable feedstocks conversion. The Mo:W ratio in bimetallic carbide can determine the product distribution. High Mo/W ratio favors aldehydes and alcohols, while low Mo/W ratio favors alkenes. H2 chemisorption is recommended for assessing the intrinsic activity of these catalysts.

Summary: Reducing electron-phonon scattering is important for achieving high conductivity in materials at room temperature. This study focused on OH-terminated MXenes, such as Hf2C(OH)2 monolayer, which showed nearly free electron states (NFESs) with weak electron-phonon scattering and high conductivity. However, it was found that the high conductivity in these materials cannot be solely attributed to the presence of NFESs, as it also depends on the band velocity and electron-phonon coupling.

Summary: The study compares Ar and N-2 adsorption isotherms of non-graphitized carbon blacks to choose the best reference material for surface area determination. Microporous carbon blacks and capillary condensation reference blacks both underestimate surface area. Surface area determination with Ar adsorption is more affected by reference carbon blacks' microporosity than with N-2 adsorption. An open repository provides optimized reference data and calculations for precise characterization of porous carbons using the SPE method.

Summary: Molybdenum carbides, specifically the alpha-MoC phase, exhibit enhanced CO2 adsorption, making them more efficient catalysts for CO2 hydrogenation at 130 degrees C. The synergistic effect of photothermal catalysis results in at least a 45% increase in activity compared to thermocatalysis on the same catalysts, due to light-promoted surface intermediate dissociation, specifically formate species. This study provides new insights into the photothermocatalytic synergistic effect.

Summary: This study utilized hydrothermally treated MgO particles to prepare porous carbons, and evaluation of the electrode materials in electric double-layer capacitors showed that the balanced ratio of micropore volume to mesopore volume in the carbons is crucial for achieving high volumetric capacitance and good rate performance. The prepared porous carbons retained 93% of the initial capacitance after 10000 cycles, indicating their potential for long-term stability and application in energy storage devices.

Summary: New types of Cu-doped spherical-shaped activated carbons were prepared by pyrolysis of chitosan hydrogels impregnated with KOH at different ratios. Cu doping resulted in bead-shaped activated carbons with high specific surface areas, while varying impregnation ratios led to changes in porosity from microporous to both microporous and mesoporous. Characterization techniques revealed the presence of N-enriched carbons with pyridinic and pyrrolic groups in the beads.
