The design of an efficient catalytic system with low Pt loading and excellent stability for the acidic oxygen reduction reaction is still a challenge for the extensive application of proton‐exchange membrane fuel cells. Here, a gas‐phase ordered alloying strategy is proposed to construct an effective synergistic catalytic system that blends PtM intermetallic compounds (PtM IMC, M = Fe, Cu, and Ni)...
Transition metal oxides with high theoretical capacities are promising anode materials for lithium‐ion batteries (LIBs). However, the sluggish reaction kinetics remain a bottleneck for fast‐charging applications due to its slow Li+ migration rate. Herein, a strategy is reported of significantly reducing the Li+ diffusion barrier of amorphous vanadium oxide by constructing a specific ratio of the VO...
Developing a rapid and low cost approach to access atomically dispersed metal catalysts (ADMCs) supported by carbon is important but still challenging. Here, an electric flash strategy using high voltage for the rapid fabrication of carbon‐supported ADMCs within 1 min is reported. Continuous plasma arc results in nitrogen‐doped carbon ultrathin nanosheets, while an intermittent spark pulse constructs...
