Descripción
Sumario:In this work, a micron-sized three-way nitrogen-doped carbon tube covered with MoS(2) nanosheets (TNCT@MoS(2)) was synthesized and applied in photocatalytic water splitting without any sacrificial agents for the first time. The micron-sized three-way nitrogen-doped carbon tube (TNCT) was facilely synthesized by the calcination of commercial sponge. The MoS(2) nanosheets were assembled on the carbon tubes by a hydrothermal method. Compared with MoS(2), the TNCT@MoS(2) heterostructures showed higher H(2) evolution rate, which was ascribed to the improved charge separation efficiency and the increased active sites afforded by the TNCT.
