Core–Shell Nanostructures-Based Porous Carbon Nanomaterials for Oxygen Reduction Reaction

Abstract

In the recent days, core–shell nanostructures (CSNs) have attracted considerable attentions in various applications such as drug delivery, adsorption of metals and organic compounds, nano-coatings, catalysis, and energy and environmental applications due to the availability of abundant surface area with controlled pore volume and pore diameter. In addition, the CSNs have the ability to tune the surface property either in the core or shell based on the necessity and end-use of applications. The CSNs produced by the use carbon-based compounds or preparing a hybrid material by wrapping of a porous carbon on the CSNs would facilitate to enhancement of electrical property due to the conducting nature of the porous carbon as well as conducting transition metals or metal oxides in the CSNs. This behaviour is much useful for energy conversion application because of the easier electron transfer phenomena. So, in this chapter, we would like to focus the CSNs-wrapped porous carbon-based nanomaterials for oxygen reduction reaction (ORR).
