Summary: Na metal is considered as a potential anode material for next-generation batteries, but its practical applications are limited due to dendrite growth and volume changes. In this study, a 3D Cu foam skeleton with hierarchical ZnO nanorod arrays was developed as a stable host for dendrite-free Na metal anodes. The sodiophilic ZnO nanorod arrays provided abundant nucleation sites for Na, resulting in homogeneous nucleation and uniform growth on the electrode, leading to dendrite-free morphology and excellent cycling stability.

Summary: An artificial protective layer with interface defects is proposed to improve the cycling stability and rate performance of lithium metal anodes. The study focuses on titanium oxide (TiO2) and demonstrates that the interfacial oxygen-deficient TiO2 coating (H-TiO2) promotes lithium ion diffusion kinetics and prevents lithium dendrite formation. The H-TiO2 protective layer enables lithium metal anodes to have ultra-long cycling stability and improves the performance of full cells paired with LiFePO4 cathode.

Summary: A delayed nucleation strategy is proposed to improve the performance of Zn anodes in aqueous Zn-ion batteries. Through a liquid metal (LM) interlayer, the reduction and deposition of Zn are temporally and spatially separated, achieving fast Zn redox kinetics and dendrite-free Zn (002) deposition. The flexible anode (Zn@LM-AgT) demonstrates stabilized Zn plating/stripping cycling over 700 hours with reduced overpotential, and when coupled with a vanadium-based cathode, the full cell exhibits six times higher remaining capacity after 1000 cycles compared to the reference cell. The delayed nucleation mechanism provides a novel approach to high-performance metallic anodes.

Summary: Electrochemical reduction of biomass-derived 5-hydroxymethylfurfural (HMF) to produce 2,5-dihydroxymethylfuran (DHMF) is a promising approach for biomass upgrading. In this study, a cooperative catalyst consisting of Ag nanoparticles (AgNPs) supported on SnO2 nanosheet arrays was synthesized, enabling efficient and selective electrochemical reduction of HMF to DHMF. The AgNPs promote water splitting to generate reactive hydrogen species (H*), which react with HMF via a Langmuir-Hinshelwood mechanism. Furthermore, the AgNPs accelerate the formation of oxygen vacancies on SnO2 under reaction conditions, facilitating the selective adsorption and hydrogenation of the carbonyl bond in HMF.
