Interface‐Engineered MoSe2‐Co9S8 Nanoheterostructures with Enhanced Charge Storage Performance for Supercapacitor Application

Cobalt-based chalcogenides have emerged as fascinating materials for supercapacitor applications owing to the presence of various mixed valance oxidation states in their structure along with rich electrochemical properties. However, their limited stability and cyclic performance hinder their viability for practical use in supercapacitors. Herein, a facile hot injection colloidal route is demonstrated to design MoSe
