Scope of this topic and related important content

The content of this topic page covers information on heterogeneous approaches that are relevant for the reduction of CO₂. To get the right context and preceding information, reading the higher level topics CO2 conversion and Photocatalytic CO2 conversion might be helpful.

Distinction from other articles within the topic >Photocatalytic CO2 conversion

>Photocatalytic CO2 conversion can be formally split into processes using homogeneous catalysis or heterogeneous catalysis for the conversion of the starting material CO₂. In this article, we focus on the heterogeneous catalysis which involves a catalyst that is not in the same phase as the reactants. The catalyst is usually solid or immobilized to a solid phase. For further information, please see related literature.[RAi16]

The related topic >Homogeneous photocatalytic CO2 conversion refers to reactions that involve a catalyst that is in the same different phase, usually dissolved in a solvent. For further reading, see related literature at the page Homogeneous photocatalytic CO2 conversion.

Important aspects of heterogeneous photocatalytic CO2 conversion

In comparison to homogeneous photocatalytic CO₂ conversion, heterogeneous processes benfit from usually from catalyst reusability. As heterogeneous catalysts are typically immobilized on a solid support, they allow for easier separation and recycling of the catalyst after the reaction.
