The lower conductivity of MoS 2 sheet presents a huge barrier for the exploitation of its supercapaciator electrode application. To alleviate this difficulty, MoS 2 quantum dots (QDs) having high surface area is prepared. The synthesized MoS 2 QDs are embedded into polyaniline (PANI)‐N,N‐dibenzoyl‐L‐cystine (D) aerogel matrix for application in high performance supercapaciator. Here, conductive PANI hydrogel are prepared by in situ polymerization of aniline where D acts as a gelator, dopant, and cross‐linker. The D‐PANI aerogel shows conductivity of 0.02 S cm −1 , specific capacitance of 278 F g −1 at a current density of 1 A g −1 . The optimal MoS 2 QDs in D‐PANI aeogel improves specific capacitance up to 796.2 F g −1 at 1 A g −1 showing long cycling stability (86% after 5000 cycles).
