CuCo‐Layered Double Hydroxide Nanosheets Grown on Hierarchical Carbonized Wood as Bifunctional Electrode for Supercapacitor and Hydrogen Evolution Reaction

open access: yesAdvanced Science, EarlyView.
The N/P co‐doped carbonized wood (NPCW) with open channels is used as the carrier, and in situ uniformly grown copper nanoparticles (Cu NPs) as nucleation centers to induce the vertical growth of CuCo‐LDH nanosheets along the substrate, forming a “carbon‐metal‐LDH” tertiary conductive network, which realizes the synergistic enhancement of high ...

High Oxidation State V‐O‐Co Structure Promotes the Role of V‐*O Intermediates in Efficient HMF Oxidation

open access: yesAdvanced Science, EarlyView.
By designing a high oxidation state VH‐O‐CoH structure, the V‐*O intermediate can be effectively generated, thereby facilitating the catalytic oxidation of HMF. This innovative design strategy demonstrates broad applicability, as it not only enables the formation of the active intermediate in various materials (V‐Ni2P), but also facilitates its ...

Serine Grafted Silica Coated Nanoscale Zero‐Valent Iron with Enhanced Fenton‐Like Degradation of Mixed Organic Solvents of Tributyl Phosphate and n‐dodecane

open access: yesAdvanced Science, EarlyView.
Serine grafted silica coated nanoscale zero‐valent iron is synthesized. Through the SiO2 coating and serine grafting, the aggregation and oxidation of nZVI are reduced, and the slow release of Fe2+ ensured the catalytic cycle. The adsorption capacity for TBP and n‐dodecane is higher, because of the synergistic effect of surface functional groups.
