Summary: Anode-free lithium batteries with high-initial-efficiency, long-cycle-life, and long-calendar-life have been achieved by using an organic Li salt monolayer bonded on Cu. The functional salt results in the formation of a LiF-rich interphase on Cu and guides Li nucleation and growth, reducing Li loss and suppressing galvanic Li corrosion and Li-electrolyte reactions. The activated cell retains 95.2% capacity after 600 cycles and shows no performance damage during calendar aging.

Summary: In this study, the behavior of water at the interfaces of mesoporous silicas was controlled by modifying their thermal and chemical properties. The results showed that the decrease in surface polarity of inorganic silicas reduced the hydrogen-bonding of water and increased the surface water diffusivity. In contrast, the decrease in polarity of organosilicas decreased the surface water diffusivity, indicating enhanced hydrophobic hydration. These findings validate the control of hydrophobic hydration at interfaces by the microscopic length scale of the hydrophobic regions, and suggest that the hydration thermodynamics of silica surfaces can be tuned to promote adsorption and selectivity in catalytic reactions.

Summary: Aluminium doped zinc oxide (AZO) shows promise as an electron transport layer (ETL) in low-temperature solution processes for hybrid perovskite solar cells (PvSCs) as a replacement for TiO2. By using a thin interfacial modification layer of monoethanolamine (MEA), the energy barrier between AZO/perovskite is reduced, accelerating charge transfer and passivating trap states. The champion PvSCs achieved an improved power conversion efficiency (PCE) of 8.25%, with a current density (J(SC)) of 22.59 mA/cm(2) and fill factor (FF) of 46.55%, and maintained 70% of its topmost PCE after 1000 hours without encapsulation. This MEA-based interface engineering offers a feasible and excellent strategy to enhance the efficiency and stability of planar PvSCs.

Summary: A polydopamine/defective ultrathin mesoporous graphitic carbon nitride (PDA/DCN) Z-scheme organic assembly was successfully fabricated through high-temperature surface hydrogenation and ultrasonic freeze-dried strategies. The assembly exhibited high photocatalytic hydrogen evolution and organic contaminant removal rates under visible and near-infrared light irradiation. The enhanced performance can be attributed to the defects of DCN that enhance interactions with PDA, leading to effective charge separation and rapid transfer. Additionally, PDA extends the photoresponse to the near-infrared region and induces photothermal effect, further increasing the reaction rate of the photocatalytic system.

Summary: Interface engineering is an efficient strategy to improve photocatalytic performance. In this study, reduced graphene oxide/mesoporous titanium dioxide nanotube heterojunction assemblies (rGO/TiO2) were fabricated via a hydrothermal method. The heterojunction interface formed between rGO and TiO2 nanotubes acts as efficient charge transfer channels, which leads to enhanced photocatalytic performance. The rGO/TiO2 heterojunction assemblies exhibit extended photoresponse to visible light and a significantly higher photocatalytic hydrogen production rate compared to TiO2 nanotubes alone. This enhancement is attributed to effective charge transfer channels, spatial charge separation, and the electron acceptor properties of rGO, as well as the large surface area and sufficient surface active sites provided by the two-dimensional mesoporous nanosheets structure. This heterojunction assembly holds potential applications in energy fields.
