The hybrid catalyst exhibited significantly enhanced performance compared to the individual catalysts (Cu-I-bpy and CeO2) in terms of hydrogen evolution efficiency and pollutant degradation rate. The mechanism investigation confirmed a direct Z-scheme charge transfer mechanism in the CeO2/Cu-I-bpy, leading to improved electron-hole separation efficiency and simultaneous reduction and oxidation abilities. This work demonstrates the potential of turning wastewater into energy resources using carefully designed photocatalytic systems.

Summary: The low activity of hydrogen oxidation reaction (HOR) in alkali conditions hinders the deployment of Ni catalysts in anion exchange membrane fuel cells (AEMFCs) due to imbalanced binding energies of hydrogen (HBE) and hydroxyl (OHBE) species. In this study, constructing a heterostructure between Ni nanoparticles (NPs) and nitride of Ni-Mo alloy (Ni0.2Mo0.8N) by an in situ synthetic strategy was found to further improve the activity. The as-fabricated heterostructured catalyst (Ni/Ni0.2Mo0.8N/rGO) supported by reduced graphene oxide (rGO) displayed state-of-the-art activity, faster kinetics, and ultrahigh durability.

Summary: Inspired by chameleon skins, ZnS-silica photonic crystals with tunable colors are fabricated. They show intense reflectance, wide photonic bandgaps, and large peak areas due to large refractive index contrast and non-close-packing structure. By adjusting particle volume fraction, colors can be easily tuned, and a lower thickness threshold is required for maximal reflectance compared to silica crystals. Various photonic superstructures can be created using the core-shell structure of the particles. A new information encryption technique based on reversible disorder-order switch of water-responsive photonic superstructures is developed. ZnS-silica crystals also enhance fluorescence significantly.

Summary: Photocatalytic production of H2O2 is a potential green route to a greener future. However, the productivity is limited by rapid electron-hole separation and low oxygen reduction activity. In this study, a series of carbon nitrides with covalently bonded dual-functional ligands were designed to enhance H2O2 production and stability. The best-performing carbon nitride showed a high production rate and excellent stability. Mechanistic studies revealed that H2O2 was produced through a 2e(-) oxygen reduction reaction route. The excellent photocatalytic performance was attributed to the dual-functional ligand.

Summary: This study presents a synergistic defect passivation method for perovskite solar cells (PSCs) by using an ionic liquid precursor engineering strategy and two-stage annealing treatment. The multifunctional groups from the ionic liquid effectively passivate the intrinsic defects, while the two-stage annealing treatment controls the formation of hydrophobic complexes along grain boundaries and surfaces. As a result, both deep- and shallow-level defects in the bulk, at grain boundaries and surface are sufficiently passivated, leading to an impressive champion efficiency of 24.20%. The resulting unencapsulated films and devices also exhibit admirable stability under various conditions. The study provides an efficient strategy for improving the efficiency and stability of PSCs.

Summary: Compared to freshwater resources, seawater is a cheaper and more abundant alternative. However, the presence of chloride ions in seawater affects the oxygen evolution reaction, necessitating the development of efficient anode catalysts for direct electrolytic seawater splitting. Non-noble metal materials show promising industrial application prospects due to their availability and low cost. In this study, we classify and summarize these catalyst materials based on structural analysis, mechanism research, and application conditions, providing insights into the current research status of non-noble metal electrocatalysts for seawater splitting.

Summary: A series of carbon-doped, amorphous titania samples were prepared and their effects on anatase growth and anatase-to-rutile transition (ART) were investigated. Carbon doping promoted the ART process and lowered the temperature required, while inhibiting anatase growth. Structural criteria for the anatase phase were determined, and samples with defined anatase/rutile mixed (ARM) phases were fabricated. It was found that anatase size of approximately 25 nm and rutile fraction of about 16% yielded optimal photocatalytic performance for the degradation of gaseous acetaldehyde under UV light.

Summary: It has been found that the introduction of buffer layers improves the electrical performance of solid oxide fuel cells (SSOFCs). In this study, varying ratios of Gd-doped CeO2 were used as buffer layers in YSZ-based SSOFCs. The results demonstrate that the performance of SSOFCs is enhanced when a buffer layer is added, with the highest performance achieved using Ce0.8Gd0.2O2-delta (GDC20) as the buffer layer. This suggests that the use of GDC series buffer layers is an attractive strategy to optimize performance loss due to electrolyte-electrode interactions.

Experimental data shows that CsPbI3 nanorods have an extremely high two-photon absorption cross-section, significantly surpassing organic chromophores and other CsPbBr3 nanocrystals. Moreover, adjusting the aspect ratio can significantly enhance the absorption ability. Additionally, the study also reveals a moderate quantum confinement effect on the single-photon and two-photon absorption cross-section of the nanorods.
