Abstract

Carbon dioxide gas is a serious problem in the modern era. Reducing its content is a crucial significant issue in the modern material and engineering sciences. Currently, carbon allotropes are recommended as excellent agents in carbon dioxide capturing. In this book chapter, the basic properties, types, synthesis methods, and mechanical, chemical and physical properties of carbon allotropes in carbon dioxide capturing were reviewed and discussed. These materials are supercapacitors for carbon dioxide. Carbon allotropes are good adsorbents for various gas: CO₂ (76.5 mg g⁻¹ at 298 K), CH4 (16.8 mg g⁻¹ at 298 K) and H₂ (12.1 mg g⁻¹ at 77 K). The selectivity of carbon allotropes for carbon dioxide capturing is high, confirming that this material effectively adsorbs the ...
