The content of this topic page covers information on homogeneous approaches that are relevant for the reduction of CO<sub>2</sub>. Currently, the information on this page is limited to information on the conversion of CO2 to CO, CH4 and CHOOH, further extension of the content is planned in the future. To get the right context and preceding information, reading the higher level topics [[:Category:CO2 conversion|<u>CO2 conversion</u>]] and [[:Category:Photocatalytic CO2 conversion|<u>Photocatalytic CO2 conversion</u>]] might be helpful.

In this case, the catalyst and the reactants are well-mixed and form a single phase throughout the reaction. The catalyst interacts directly with the reactants, forming an intermediate complex, which then undergoes a reaction to form the desired products. Homogeneous catalysis often involves the use of transition metal complexes or organocatalysts. One advantage of homogeneous catalysis is that the catalyst can be precisely tuned and controlled to promote specific reactions. Reviews for further reading focusing on homogeneous photocatalytic CO<sub>2</sub> conversion are available.{{#literature:|doi=https://doi.org/10.3390/catal2040544}}


The related topic >[[Homogeneous photocatalytic CO2 conversion|Heterogeneous photocatalytic CO2 conversion]] refers to reactions that involve a catalyst that is in a different phase (typically solid) from the reactants. The reactants are in a different phase (liquid or gas) and come into contact with the solid catalyst, which is usually in the form of a powder or a material such as a modified surface or material in general. The reactants adsorb onto the surface of the catalyst, where the catalytic reaction occurs. For further information, please see chapter heterogeneous photocatalytic CO2 conversion and literature links therein.

In comparison to heterogeneous photocatalytic CO<sub>2</sub> conversion, homogeneous processes benfit from usually a uniform distribution of the catalyst in the reaction medium, faster reaction rates due to better contact between the catalyst and reactants, and a simpler reactor design due to the application of the catalyst in solution, whereas in heterogeneous systems, the catalyst often needs to be immobilized on a support material.
In comparison to homogeneous photocatalytic CO<sub>2</sub> 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.

Scope of this topic and related important content[edit | edit source]

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[edit | edit source]

>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[edit | edit source]

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.
