This study presents a novel nitrogen-doped carbon-wrapped CoO prepared by a facile impregnation-carbonization process using low-cost raw materials. The optimized catalyst exhibits the highest activity reported to date for Co-based catalysts used in the reduction of p-nitrophenol to p-aminophenol with NaBH and remains highly stable over seven continuous runs.

The development of nanohybrid with high electrocatalytic activity is of great significance for electrochemical sensing applications. In this work, we develop a novel and facile method to prepare a high-performance flexible nanohybrid paper electrode, based on nitrogen-doped carbon (NC) wrapped Bi nanoparticles (Bi-NPs) assembly derived from Bi-MOF, which are decorated on a flexible and freestanding graphene paper (GP) electrode. The as-obtained Bi-NPs encapsulated by an NC layer are uniform, and the active sites are increased by introducing a nitrogen source while preparing Bi-MOF.

Zinc-vanadium oxides have been attracting increasing consideration as anode materials for lithium/sodium-ion batteries (LIBs and SIBs) recently. Present applications are hampered by issues, including their inferior electric conductivity and enormous volume variation. Herein, nitrogen-doped carbon wrapped ZnVO (ZnVO/NC) microspheres composed of abundant nanosheets were developed as an anode material by a self-assembly strategy and subsequent surface decoration.

Earth-abundant transition-metal selenides (TMSs) have aroused great interest towards their application in sodium-ion batteries (SIBs). Herein, we present Fe-based Prussian blue analogs (PBA) modified by graphene oxide as precursors to synthesize FeSe2 nanoparticles within a nitrogen-doped carbon (NC) matrix and graphene layer (FeSe2/NC@G). The bifunctional carbon wrapped FeSe2/NC@G shows excellent sodium-storage performance with a large reversible capacity of 331 mA h g-1 at 5.

Metal selenides as highly efficient bifunctional electrocatalysts were extensively applied to water-splitting technology. In present work, N-doped graphitized carbon wrapped CoSe nanoparticles (NPs) with in-situ grown bamboo-like carbon nanotube (CoSe@N/C-CNT) was successfully synthesized via a Co-Ade (Adenine) MOF-derived selenylation strategy. Each CNT was capped with CoSe NP, which not only effectively avoided self-agglomeration of CoSe NPs but also protected the CoSe NPs from electrolyte etching.
