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

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.
