Liquid Metal–Polyphenol Hybrids for Solar Steam Generation

Advanced Science, EarlyView.
The combination of liquid gallium nanoparticles, graphene, and a metal‐phenolic gel creates a unique architecture that can act as a highly efficient broad–spectrum solar light absorber. The resulting composite applied for solar steam generation can produce clean water with an evaporation rate of 3.4 kg m−2 h−1 under 1 Sun illumination from seawater ...

Optimizing Surface *H Coverage over Cu2O/Co3O4 Heterojunction Enables Efficient Neutral Electrocatalytic Hydrogenation of 5‐hydroxymethylfurfural to 2,5‐dihydroxymethylfuran

Advanced Science, EarlyView.
This work presents a heterojunction strategy, wherein Co3O4 functions as a redox‐active cocatalyst to stabilize Cu⁺ sites and finely tune the electronic structure of Cu2O. Such interfacial modulation accelerates H2O dissociation kinetics under neutral conditions and enables optimal surface *H coverage, thereby facilitating efficient HMF electro ...

Boosting Electrochemical Capacitive of Ultrathin Shower‐Pouf Birnessite‐Type MnO2 for Porous High‐Mass‐Loading Energy Storage Device

Advanced Science, EarlyView.
Ultrathin Shower‐pouf Birnessite‐type MnO2 (thickness: ~3 nm) has been fabricated via the specific adsorption of fluoride ions on the (001) crystal plane of birnessite. By constructing an electrically conductive network and optimizing electrode slurry concentration, the electrode mass loading can be substantially improved. These electrodes also exhibit

Water Electrolysis Beyond Platinum: Carbon Nitride Materials for Electrochemical Hydrogen Evolution

Advanced Science, EarlyView.
Porous long carbon nitride nanoscrolls can be activated by subpotential reduction to become effective electrocatalyts for electrochemical hydrogen evolution (HER) and storage, with a performance superior to Platinum. The optimized system displays an overpotential close to commercial Pt/C but provides a superior current density (1.3 A/cm2), turnover ...
