ABSTRACT=<p>In this work, a micron-sized three-way nitrogen-doped carbon tube covered with MoS<sub>2</sub> nanosheets (TNCT@MoS<sub>2</sub>) 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<sub>2</sub> nanosheets were assembled on the carbon tubes by a hydrothermal method. Compared with MoS<sub>2</sub>, the TNCT@MoS<sub>2</sub> heterostructures showed higher H<sub>2</sub> evolution rate, which was ascribed to the improved charge separation efficiency and the increased active sites afforded by the TNCT.</p>
