More active sites exposed few-layer MoSe2 supported on nitrogen-doped carbon as highly efficient and durable electrocatalysts for water splitting

Nitrogen-doped carbon supported fewer-layer MoSe2(FL-MoSe2/NC) is demonstrated to be an efficient catalyst for the HER. The NC plays an important role in the high performance of the FL-MoSe2/NC. It facilitates the formation of MoSe2 with few layers and shorter lattice fringe lengths and the exposure of more active sites to the HER.412
