One-pot synthesis of MoSe2 hetero-dimensional hybrid self-assembled by nanodots and nanosheets for electrocatalytic hydrogen evolution and photothermal therapy
We designed and prepared a hetero-dimensional hybrid (HDH) based on molybdenum selenide (MoSe2) nanodots (NDs) anchored in few-layer MoSe2 nanosheets (NSs) (MoSe2 HDH) via a one-pot hydrothermal process. The MoSe
