Bimetallic carbides embedded in heteroatom-doped carbon nanotubes for efficient electrocatalytic hydrogen evolution reaction and high-performance lithium storage

A General Self‐Assembly Induced Strategy for Synthesizing 2D Ultrathin Cobalt‐Based Compounds Toward Optimizing Hydrogen Evolution Catalysis

“…Given that most TMCs are semiconductors and could not be directly used in their block states, different methods are explored to promote the electron transfer and/or transport during electrocatalysis. The most common approach is compositing with conductive substrates, such as nickel foam, [8] graphene, [9] carbon nanotubes, [10] etc. The characteristics of substrates and varied loading manners exert different effects on the electronic structure and catalytic behaviors of active TMCs.…”

N-Doped Carbon–WS2 Nanosheet Composites for Lithium-Ion Storage

“…The detailed pseudocapacitive fraction (yellow part) at 2.0 mV s –1 is presented in Figure d. The prominent pseudocapacitive process is due to the fact that more redox reaction sites exist on the surface of anode material, which endows fast reaction kinetics, resulting in a superior rate performance. , The outstanding lithium-storage performance could be ascribed to two aspects. On the one hand, a hierarchical carbon structure can not only enhance the conductivity of WS 2 but also prevent the aggregation of the WS 2 nanosheets.…”

Interface engineering of tungsten carbide/phosphide heterostructures anchored on N,P-codoped carbon for high-efficiency hydrogen evolution reaction

“…S4). The highresolution W 4f spectrum exhibited six fitting peaks, where the two dominant peaks at 32.0 and 34.2 eV were assigned to W-C [41,42], and the pair of small peaks at 32.9 and 35.2 eV were assigned to W-P (Fig. 1d) [43].…”
