In situ integration of cobalt diselenide nanoparticles on CNTs realizing durable hydrogen evolution

Abstract

The CoSe2/CNT composites are integrated as electrocatalysts for the hydrogen evolution reaction, providing a new way to construct durable electrocatalysts from transition metal compounds.

CoP2/Co2P Encapsulated in Carbon Nanotube Arrays to Construct Self-Supported Electrodes for Overall Electrochemical Water Splitting

“…More importantly, the protected TMP nanoparticles inside CNTs are less vulnerable, which is conducive to promoting the stability of TMPs@CNTs . We envision the advantages of self-supported electrodes as follows: (i) the catalytic active materials can be firmly and uniformly anchored and dispersed on the CC, thereby improving the structural stability of the materials; (ii) the catalytic materials are seamlessly contacted to the CC, which facilitates the charge transfer; (iii) the elimination of binders results in the reduction of cost and the alleviation of masking the active sites; and (iv) the hydrophilicity of the electrode surface can be easily changed after optimizing the morphology or microstructure of the catalytic active material. , Despite various TMPs@CNTs having been reported, ,,− uniform filling of composite nanoparticles encapsulated into CNTs is still far from satisfactory. Therefore, regulating the growth of TMP composite nanoparticles in CNTs is of great importance.…”
