Open-ended W(18)O(49)-filled tungsten dichalcogenide nanotubes grown on a W substrate to efficiently catalyze hydrogen evolution

A scalable infrared-heating CVD method was developed to grow few-walled WSe(2) or WS(2) nanotube arrays in situ filled with highly conductive single-crystal W(18)O(49), and a simple pressure control led to their universally uncapped top-ends. Open-ended WS(2) nanotubes grown on the W substrate perfo...

Descripción
Sumario:A scalable infrared-heating CVD method was developed to grow few-walled WSe(2) or WS(2) nanotube arrays in situ filled with highly conductive single-crystal W(18)O(49), and a simple pressure control led to their universally uncapped top-ends. Open-ended WS(2) nanotubes grown on the W substrate performed excellently as an electrocatalyst to facilitate the HER in acid, contributing to high-density active edge sites and good electronic coupling between the substrate and nanotubes.
