Micro and Nanoporous Membrane Platforms for Carbon Neutrality: Membrane Gas Separation Prospects

Abstract Recently, carbon neutrality has been promoted as a potentially practical solution to global CO 2 emissions and increasing energy‐consumption challenges. Many attempts have been made to remove CO 2 from the environment to address climate change and rising sea levels owing to anthropogenic CO 2 emissions. Herein, membrane technology is proposed as a suitable solution for carbon neutrality. This review aims to comprehensively evaluate the currently available scientific research on membranes for carbon capture, focusing on innovative microporous material membranes used for CO 2 separation and considering their material, chemical, and physical characteristics and permeability factors. Membranes from such materials comprise metal‐organic frameworks, zeolites, silica, porous organic frameworks, and microporous polymers. The critical obstacles related to membrane design, growth, and CO 2 capture and usage processes are summarized to establish novel membranes and strategies and accelerate their scaleup.
