Summary: The study proposes a self-floating absorber based on kapok fibers, which utilizes its large hollow structure and hydrophobicity to float on water for interfacial evaporation. Gold nanoparticles loaded on kapok fibers by in-situ synthesis extend the absorption wavelength range (74.7%) from 280 to 2500 nm. The hollow structure of kapok fibers and the thermal localization effect of AuNPs substantially enhance the solar interfacial vapor generation (4 kW m(-2), up to 89%). The AuNPs/kapok membrane exhibits stable cycling performance with an evaporation rate of 6.98 kg m(-2) h(-1) over 10 cycles.

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.
