Synergistic effect of three-dimensional cobalt diselenide/carbon nanotube arrays composites for enhanced hydrogen evolution reaction

An integrated structure of three-dimensional CoSe2/carbon nanotube arrays (CoSe2/CNTAs) composite was synthesized through a microwave-assisted selenization method. The CoSe2/CNTAs composite displays greatly improved performance in comparison with pure CoSe2 and CoSe2/CNTs.265
