Summary: This study demonstrates that different crystal facets have significant effects on the catalytic performance in the gas-phase degradation of NO. ZnO crystals with lower flat-band energy and enhanced (0002) facet show better performance in the photoelectrochemical water-oxidation, while those with exposed (101(-)1) facet have higher affinity to NO molecules. Additionally, the oxygen vacancies play a minor role in the photocatalytic oxidation of NO.

Summary: The study investigated the facet-dependent photocatalytic H2O2 generation activities of BiOCl nanosheets, and found that BiOCl(001) has a higher hydrogen peroxide evolution rate compared to BiOCl(010). Different pathways for H2O2 production on the two facets were identified, with BiOCl(001) mainly generating H2O2 through sequential two step single-electron O-2 reduction.

Summary: The photocatalytic degradation of per- and polyfluoroalkyl substances (PFAS) using BiOCl nanosheets with {010} or {001} facets showed that {010}-BiOCl exhibited higher catalytic activity compared to {001}-BiOCl in the degradation of perfluorooctanoic acid (PFOA). The higher catalytic activity of {010}-BiOCl was attributed to the in-situ generated surface oxygen vacancies and strong interaction with PFOA molecules. Furthermore, the nanosheets with {010} facets showed the highest adsorption capacity and lowest adsorption energy for PFOA molecules, while photogenerated holes and surface hydroxyl radicals on {010} facets played a significant role in the degradation process. Additionally, F- ions as by-products tended to block the catalytic sites but could be removed using a simple chemical precipitation approach with Ca2+ ions to recover the catalytic performance.

Summary: Based on scanning transmission electron microscopy, direct evidence is provided to show how the metal-support interaction affects the structure of supported nanoparticles. It is found that Pt nanoparticles on CeO2 exhibit facet-dependent support interaction, which determines the dimensionality of the particles. Pt particles consisting of less than approximately 130 atoms prefer a 3D shape on CeO2(111) facets, while 2D raft structures are favored on CeO2(100) facets.

Summary: Defect engineering is an effective method to improve the photocatalytic performance of TiO2. This study investigates the synergy between oxygen vacancy (V-O) defects and crystal facets in TiO2 nanostructures and their impact on photocatalytic O-2 activation. The results show that a high concentration of V-O combined with the {101} facet significantly enhances the photocatalytic performance compared to other combinations. This study provides valuable insights into the role and interaction of defects and facets in photocatalysts.

Summary: In this study, the photocatalytic oxidative coupling of methane (OCM) over transition-metal-loaded ZnO photocatalysts was systematically investigated. A 1 wt% Au/ZnO catalyst exhibited remarkable C-2-C-4 hydrocarbon production rate and selectivity under light irradiation. The selectivity towards C-C coupling products strongly depends on the metal type and its interaction with ZnO. The findings suggest that the d-sigma center can be a suitable descriptor for predicting product selectivity during OCM over metal/ZnO photocatalysts.

Summary: In this study, a photocatalyst constructed with a small amount of amorphous BiOCl nanosheets assembled on TiO2 showed excellent performance in toluene oxidation to benzaldehyde. The selectivity reached 85% at 10% conversion, and the benzaldehyde formation rate was significantly higher than that of bare TiO2 and BOC. The microstructure based on heterojunctions and the presence of surface oxygen vacancies in the amorphous BiOCl were found to be crucial for the high selectivity and performance.

Summary: In this study, uniform Pd nanocrystals with cube and octahedron geometries were synthesized and combined with ultrathin TiO2(B) nanosheets for the photocatalytic dechlorination of polychlorinated biphenyls. The CUB/TBs showed a 200% enhancement in efficiency compared to OCT/TBs, attributed to the higher surface charge density of CUB promoting the activation of C-Cl bonds. This research not only elucidates the effect of facet-engineering Pd nanocrystals on the photocatalytic dechlorination of polychlorinated biphenyls but also lays the foundation for superior photocatalysts for other advanced applications.

Summary: This study presents an atomically precise material model for photocatalysis, which incorporates Fe species into polyoxotitanium cluster to form a heterometallic Ti4Fe1 cocrystal. This cocrystal cluster effectively controls the energy and charge transfer, allowing the synergistic process of C(sp(3))-H bond activation by photogenerated holes and reactions by singlet oxygen. The Ti4Fe1 cluster achieves efficient and selective oxidation of hydrocarbons, outperforming Fe-doped Ti3Fe1 cluster in terms of conversion rate.

Summary: By introducing TPP to control the preferential growth of BiVO4 (010) crystal surface, a novel ternary BiVO4/CQDs/TPP photocatalyst was constructed, showing an enhanced water oxidation rate with efficient electron-hole transfer between TPP and BiVO4 via CQDs as electron mediator. The surface photovoltage and transient absorption spectroscopy confirmed the efficient charge behavior, and density functional theory calculation revealed the more energetically favorable water dissociation on the (010) facet surface of BiVO4/CQDs/TPP-60 compared to pristine BiVO4.

Summary: Artificial photocatalysis is a promising method for selective conversion of CH4 to CH3OH, but the over-oxidization by active oxygen radicals hinders its efficiency. In this study, a strategy of transferring key intermediates for stability was proposed. A Co3O4/ZnO composite photocatalyst effectively converted CH4 to CH3OH under simulated sunlight irradiation, while pure ZnO only over-oxidized CH4 into CO2. Co(3)O(4) was found to play a crucial role in adsorbing .CH3 key intermediates and desorbing CH3OH to suppress CH4 over-oxidation on the ZnO surface.

Summary: A universal strategy to enable large electromechanical deformations in various piezoceramics is still lacking. In this study, by gradually reducing the thickness, it was discovered that thin lead-free piezoceramics can achieve large electrostrain, and the bending deformation induced by asymmetric domain switching in the surface layers plays a significant role in the enhanced strain output and shape retention effect. These findings have the potential to accelerate the development of high-performance lead-free piezoceramics.
