Summary: This study focuses on the crystal facet design of a NiCo2O4/Fe2O3 p-n heterojunction for gas sensing applications. The results show that the heterojunction exhibits superior sensing properties compared to pristine NiCo2O4 and Fe2O3 materials. Theoretical calculations suggest that the electronic coupling effect in the heterojunction enhances the interaction between the heterojunction and the target gas, leading to improved gas sensing performance.

Summary: Crystal facet engineering is an important technique for designing efficient catalysts. A phase transition strategy was developed to selectively expose {103}, {101}, and {112} facets in Mn3O4. Among these facets, {103}-exposed Mn3O4 showed the best photothermal catalytic activity in decomposing formaldehyde, achieving complete mineralization at ambient temperature. The study also revealed the photothermal synergistic decomposition process of formaldehyde. These findings not only broaden the understanding of crystal facet engineering but also provide suggestions for the purification of volatile organic compounds in indoor air.

Summary: Facet engineering was used to enhance the CO2 photoreduction performance of the Ni2P/ZnIn2S4 heterostructure by converting the commonly exposed (1 0 2) face of ZnIn2S4 to the (1 0 1) face. This increased the interfacial contact between Ni2P and ZnIn2S4, resulting in improved utilization and absorption efficiency for incident light and increased surface reaction rate. This approach also inhibited recombination and strengthened transfer efficiency, leading to significant enhancement of photoreduction activity.

Summary: This study investigated the photocatalytic degradation of naproxen (NPX), a nonsteroidal anti-inflammatory drug (NSAID) commonly found in drinking water. Fluorine-doped TiO2 with controlled morphology was synthesized and applied for photocatalytic degradation under UV-vis and visible light. The effect of morphology, specifically the {1 0 1}, {0 0 1}, and {1 0 0} facets, on the photocatalytic activity was studied. Octahedral fluorine-doped TiO2 particles with exposed {1 0 1} facets exhibited the highest photocatalytic activity and achieved complete degradation of NPX after 40 minutes under simulated solar light (UV-vis). HPLC-MS analysis suggested that the presence of {0 0 1} facets in fluorinated decahedral nanostructures hindered the mineralization rate.

Summary: Hydrogen spillover can assist in introducing defects in a TiO2 crystal, while crystal facet engineering offers a promising approach to influencing the recombination step of photo-generated electrons and holes. In this study, rutile TiO2 nanorods were synthesized with different aspect ratios and Pt-deposited TiO2-x nanorods were obtained via reduction treatment assisted by hydrogen spillover. The Pt/TNR with a higher aspect ratio reduced at 200 degrees C exhibited the highest activity in photocatalytic H-2 production under visible light irradiation due to the synergistic effect of Ti3+ defects introduction and spatial charge carrier separation induced by crystal facet engineering.
