There have been tremendous efforts to combine multiple active species into hybrid system that one has high activity for HER and the other for OER. The electrochemical performance of most hybid systems can be improved by synthesizing active species on nanostructured template which enables to maximize their active sites. To further increase the performance of hybrid system, calcination process is frequently conducted which enhances electrical conductivity and crystallinity of the obtained hetero nanostructure. During this process, active species experience changes in their morphology and the morphological changes generally lead to considerable change in electrocatalytic performance. In this work, we prepared nitrogen doped hollow carbon nanocage with Co9S8 and MoS2. The structure and performance change of the as-synthesized samples were investigated thoroughly and thus the morphology and interface of the sample were excellently modified.
