MoS ₂ nanosheets vertically grown on CoSe ₂ hollow nanotube arrays as an efficient catalyst for the hydrogen evolution reaction

-CC hybrid also demonstrated exceptional electrochemical durability and structural stability even after 1000 cycles or 48 h of continuous electrolysis. Overall, this work presents a new approach for the design and synthesis of robust, highly active, and cost-effective electrocatalysts for hydrogen generation.
