Abstract

Today, seeking for cost-effective and efficient electrocatalyst is desired because hydrogen evolution reaction (HER) has been highly recognized as a promising approach to produce clean and renewable energy. MoSe2 is an attractive candidate due to its fascinating properties. Unfortunately, aggregation as well as low conductivity restricts its developments. Here we report a smart strategy that MoSe2 nanoflakes adhered on the surface of BP nanosheets through van der Waals interactions, aiming to increase conductivity and expose much more active sites simultaneously. It is found that the prepared MoSe2-BP exhibits an enhanced electrocatalytic performance with a lower onset potential (200 mV), a smaller Tafel slope (109 mV dec-1) and excellent stability. Such this performance can be attributed to the support provided by BP, which benefit efficient electrons transfer and prevent MoSe2 from aggregating.
