This review article outlines the most commonly used methods for making the core/shell structures as the active materials for supercapacitors over the past decade (2007–2018), and points out the most efficient combination of the material categories and morphologies for the core/shell structure.

This review aims at providing an overview of the interactions between Pt and supports from experimental and theoretical results, in the hope of correlating the metal–support interactions with the activity and durability of the catalysts in fuel cells.
