A Review of Advances in Carbon Dioxide Capture with the Aim of Reusing Them as Fuel

Abstract

Currently, converting CO₂ from industrial exhaust into fuel is a challenging issue that many researchers are working on. As it is obvious, adsorption and conversion are two distinct processes, and there is a need for special materials and conditions to occur in each of them. Lately, there have been efforts to combine these two steps by using dual functional materials (DFMs) and making adsorbents and catalysts simultaneously. DFMs comprise two components. The first component of DFMs is the adsorbent, which researchers can get from oxides, carbonates, or both. The second component is the catalyst, which is typically made of metallic elements, such as Nickel or Ruthenium. Capturing systems of CO₂ by DFMs, innovative developments, and suggested ways to boost the efficiency of CO₂ capture are discussed in this review. DFMs made with changed adsorbents perform better in CO₂ adsorption and conversion, according to sources.
