Abstract
Polyaniline (PANI) has recently gained attention due to its cost-effectiveness, environmental stability,
multiple oxidation and reduction reactions, ease of handling, and electrochemical performance. Conversely,
zeolitic imidazolate frameworks have attracted interest because of their exceptional morphology, high surface
area, tunable porosity, suitable functional linkers, and metal sites. This chapter explores recent advances in the
synthesis of PANI doped with ZIF composites and their potential applications in batteries, conversion
technologies, electrocatalysis, supercapacitors, and electrochemical sensing. Additionally, insights into the Tafel
constant in HER analysis are discussed, along with its practical benefits. By reviewing current research
developments, we aim to elucidate strategies to optimise the electrochemical performance of polyaniline doped
with zeolitic imidazolate frameworks, known as PANI/ZIF composite.
