Summary: Anisotropic ZrO2 particles with octahedron-, diamond- and plate-like morphologies were successfully synthesized using a hydrothermal treatment approach with NaBF4 as a mineralizer. The concentration of mineralizers played a crucial role in controlling the shape and size of the ZrO2 particles. The introduction of NaBF4 played an essential role in tuning the crystallinity and size of primary ZrO2 nanorods, and the synergistic effect of F- and B3+ resulted in different epitaxial growth rates. The as-prepared ZrO2 particles exhibited different photocatalytic efficiencies for the degradation of organic dyes, with the highest degradation rate of 88% observed for ZrO2 photocatalyst synthesized with a 0.01 mol/L NaBF4 mineralizer under UV irradiation.

Summary: This study reports the successful synthesis of an intrinsically honeycomb-patterned form of hydrogenated graphene on Ru(0001) using epitaxial growth followed by hydrogenation. Combining scanning tunneling microscopy observations with density-functional-theory (DFT) calculations, it was revealed that an atomic-hydrogen layer intercalates between graphene and Ru(0001), resulting in a hydrogen honeycomb structure that serves as a template for the final hydrogenation, yielding honeycomb-patterned hydrogenated graphene (HPHG). This growth mechanism provides a new pathway for the fabrication of intrinsically patterned graphene-based materials.

ZnO structures with different crystal facets were obtained. The gas-sensing performances of sensors based on these structures were tested, and ZnO spheres showed the best response and fastest response time. The enhanced gas sensing properties are attributed to high-energy exposed facets and unique hollow structures. Density functional theory (DFT) was also investigated to support the effect of crystal facets.

Summary: Using density functional theory, the photocatalytic CO2 reduction of WS2-based single-atom catalysts was investigated. It was found that non-metals (B, C, and N) doped WS2 (X-WS2) could significantly enhance the photocatalytic performance of CO2 reduction. Compared to Pt@WS2, Pt@B-WS2 could reduce the Gibbs free energy from 1.41 to 1.01 eV. The introduction of the B atom improved the metal-support interaction, stabilized the Pt single-atom, and effectively promoted charge separation and transfer, leading to higher photocatalytic performance for converting CO2 to CH4. This study provides a strategy to design superior single-atom catalysts for photocatalytic conversion of CO2 to carbon-neutral fuels.
