Abstract

Increasing demands of continuous and clean energy resources create a major problem to the researchers to identify the suitable materials for future energy applications. In this context, hydrogen fuel is abundantly available due to its higher gravimetric energy density and hence used in fuel cells to produce clean energy without any harmful gas emissions. Nevertheless, storing hydrogen is the main hindrance to utilize the hydrogen economy due to its high and unsafe pressure or liquid storage that suffers from low energy per unit volume. Hence, this problem could be addressed by possible alternate hydrogen storage techniques. Up to now, there are two kinds of hydrogen storage methods that are explored such as physisorption and chemisorption. In the former case, physical interaction of bonds is weak and does not show any significant change in the sorbent material, whereas in the latter case, hydrogen interacts with the storage material through strong chemical bonds. In this context, polyaniline (PANI) is widely investigated for hydrogen storage application. Various shape, structures, and its nanocomposites with PANI have been explored for hydrogen economy due to its unique electronic property, molecular sieving phenomena, and the aromatic ring.
