Summary: Li-ion hybrid supercapacitors with high power densities are intensively studied, and this study introduces a defect-dominating structure protocol to improve the energy density of the anode material. By introducing crystal vacancies and lattice distortions in the ultrafine niobium nitride monocrystals integrated into a carbon framework, a NbN@C composite anode is created with high reversible Li-ion storage capacities, excellent rate capability, and cycling stability. First-principles density functional theory simulations confirm the extra capacity contribution of the defective NbN component. The findings from this study can inspire new structural material designs of LHSCs.

Summary: By using a 100 mM xylitol additive, the plating/stripping processes in Zn-ion batteries can achieve high reversibility. The xylitol molecules not only inhibit the hydrogen evolution reaction, but also accelerate the migration of cations through the expelling of active H2O molecules and weakening of electrostatic interactions. Additionally, the preferential adsorption of xylitol molecules on the Zn surface forms a shielding buffer layer, which hinders the sedimentation and diffusion of Zn2+ ions.

Summary: In this work, Fe-doped flower-like In2S3/Fe3S4 hetero-microspheres (Fe-In2S3/Fe3S4 HMSs) were prepared through a facile one-pot solvothermal reaction and demonstrated as efficient S-scheme photocatalysts for visible-light-driven CO2 photoreduction. The doping of Fe reduced the bandgap of In2S3, extended the optical response to the visible-light region, increased the densities of donors and sulfur vacancies, and elevated the Fermi level. The enhanced interfacial electric field resulted in promoted carrier transfer in the S-scheme pathway. Fe-doped In2S3 also reduced the formation energy of the *CO intermediate, which favored the CO evolution at the surface.

Summary: A hydrophobic-aerophilic strategy is developed to engineer the reaction kinetics at air cathodes by fabricating a self-supported air cathode based on CoS/Fe3S4 nanoparticles encapsulated in S, N co-doped carbon plate arrays (CoS/Fe3S4@SNCP). The in situ growth of bimetallic sulfides nanoparticles on the carbon plate arrays improves the intrinsic electrocatalytic activity and electron conduction of the air cathode. The hydrophobic-aerophilic surface repels water molecules and creates abundant solid-liquid-gas three-phase reaction interfaces, promoting the diffusion of reactive molecules/ions and oxygen adsorption.
