Homogeneous photocatalytic CO2 conversion

Scope of this topic and related important content

The content of this topic page covers information on homogeneous approaches that are relevant for the reduction of CO₂. 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 >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 homogeneous catalysis which involves a catalyst that is in the same phase (usually liquid or gas) as the reactants. 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.

The related topic for Heterogeneous catalysis, on the other hand, involves 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 structured material. The reactants adsorb onto the surface of the catalyst, where the catalytic reaction occurs. Heterogeneous catalysis is commonly used in industrial processes due to its advantages such as easy separation of the catalyst and the products, as well as the ability to reuse the catalyst multiple times.

In summary, the main difference between homogeneous and heterogeneous catalysis lies in the physical state of the catalyst relative to the reactants. Homogeneous catalysis involves a catalyst in the same phase as the reactants, while heterogeneous catalysis involves a catalyst in a different phase from the reactants.
