7Porous Carbon and Carbon‐based Materials via Ice Templating and Freeze‐drying

7.1 Introduction

Porous carbon materials exhibit high chemical stability and high surface area and are used in a wide range of applications. A well‐known example of carbon materials are activated carbons that are usually fabricated by carbonization of polymers or biomass, followed by activation. Activated carbons are microporous materials (pore size <2 nm) and have been extensively used as adsorbents, as catalyst supports, in gas storage, etc. Like for other types of porous materials, the tuning of pore size, porosity, and surface functionality is crucial to optimize the potential of porous carbons for use in various applications. For example, while the micropores provide ...
