Summary: Porous Mo-doped CoFeP/nitrogen doped carbon nanocubes were synthesized via phosphiding Mo-doped CoFe-Prussian blue analogue. The obtained Mo-doped CoFeP/NC exhibited excellent hydrogen evolution reaction activity, requiring an overpotential of 145 mV to reach 10 mA cm-2 and showing a small Tafel slope of 68 mV·dec-1. This indicates that doping Mo can effectively modulate the electronic structure of CoFeP/NC nanocubes.

Summary: By utilizing the flexible porous skeleton of S/N co-doped graphene aerogel (SNGA), NiCoO2 and NiCo2S4 were successfully loaded onto the SNGA surface, leading to improved reversible capacity and rate capability for lithium ion battery anode materials. The high specific surface area carbon source of SNGA contributed to the mitigated particle agglomeration of NiCoO2 and NiCo2S4, while the one-step hydrothermal process of NiCo2S4 resulted in a more compact and coherent porous structure in NiCo2S4/SNGA. These materials exhibit good stability and high rate performance, providing theoretical guidance for the further application of SNGA skeletons in lithium energy storage.

Optimal performance was observed for the capsule morphology in terms of bandgap, electrical conductivity, magnetic saturation, and photocatalytic efficiency. The mechanistic insights provided in this study could be useful for tailoring the morphologies of other ferrites for specific applications.

The hydrogen evolution reaction (HER) in water electrolysis has been studied extensively, but understanding the mechanistic insights in sophisticated nanohybrids is limited. This study investigates a low-cost fabrication of a '3D electrocatalyst' with WO3 metal oxide layered with carbon entities to decode the hydrogen spillover effect (HSPE) mechanism and assess stability profiles for HER in different environments. The results show that the 3D architecture with WO3 and reduced graphene sheets exhibits comparable kinetics to Pt, making it a promising candidate for scalable electrocatalysts in HER.
