Summary
Carbon capture and utilization (CCU) offers a promising alternative to carbon capture and storage (CCS) by converting captured carbon dioxide (CO2) into valuable chemicals. This review highlights recent advances in CCU, focusing on in situ catalytic transformations of CO2 using various absorbents.
Area of Science:
- Environmental Chemistry
- Catalysis
- Green Chemistry
Background:
- Fossil fuel combustion releases excessive CO2, driving global climate change.
- Carbon capture and storage (CCS) is a strategy to mitigate CO2, but requires significant energy for desorption and compression.
- Carbon capture and utilization (CCU) offers an energy-efficient alternative by converting captured CO2 into valuable products.
Purpose of the Study:
- To review recent progress in CO2 capture and in situ catalytic transformation.
- To elucidate the transformation mechanisms of captured CO2 and the role of absorbents.
- To highlight the potential of CCU as a sustainable strategy.
Main Methods:
- Literature review of CO2 capture and utilization strategies.
- Categorization of methods based on absorbent types.

01:19Turnover Number and Catalytic Efficiency
20.3K
The turnover number of an enzyme is the maximum number of substrate molecules it can transform per unit time. Turnover numbers for most enzymes range from 1 to 1000 molecules per second. Catalase has the known highest turnover number, capable of converting up to 2.8×106 molecules of hydrogen peroxide into water and oxygen per second. Lysozyme has the lowest known turnover number of half a molecule per second.

01:07Catalytically Perfect Enzymes
4.9K
The theory of catalytically perfect enzymes was first proposed by W.J. Albery and J. R. Knowles in 1976. These enzymes catalyze biochemical reactions at high-speed. Their catalytic efficiency values range from 108-109 M-1s-1. These enzymes are also called 'diffusion-controlled' as the only rate-limiting step in the catalysis is that of the substrate diffusion into the active site. Examples include triose phosphate isomerase, fumarase, and superoxide dismutase.

In 1928, bacteriologist Frederick Griffith worked on a vaccine for pneumonia, which is caused by Streptococcus pneumoniae bacteria. Griffith studied two pneumonia strains in mice: one pathogenic and one non-pathogenic. Only the pathogenic strain killed host mice.
Griffith made an unexpected discovery when he killed the pathogenic strain and mixed its remains with the live, non-pathogenic strain. Not only did the mixture kill host mice, but it also contained living pathogenic bacteria that...

01:28Reduction of Benzene to Cyclohexane: Catalytic Hydrogenation
5.7K
Unlike the easy catalytic hydrogenation of an alkene double bond, hydrogenation of a benzene double bond under similar reaction conditions does not take place easily. For example, in the reduction of stilbene, the benzene ring remains unaffected while the alkene bond gets reduced. Hydrogenation of an alkene double bond is exothermic and a favorable process. In contrast, to hydrogenate the first unsaturated bond of benzene, an energy input is needed; that is, the process is endothermic. This is...

02:13Reduction of Alkenes: Catalytic Hydrogenation
13.9K
Alkenes undergo reduction by the addition of molecular hydrogen to give alkanes. Because the process generally occurs in the presence of a transition-metal catalyst, the reaction is called catalytic hydrogenation.
Metals like palladium, platinum, and nickel are commonly used in their solid forms — fine powder on an inert surface. As these catalysts remain insoluble in the reaction mixture, they are referred to as heterogeneous catalysts.

Microbial communities are dynamic environments where cell lysis releases free DNA into the surroundings. Other cells can take up this extracellular DNA through a process known as transformation.When a cell incorporates this foreign DNA into its genome, resulting in genetic modification, the process is known as transformation. Cells capable of this process are termed competent. Competence can be natural, as observed in certain bacteria and archaea, or artificially induced in the...
