Abstract
Generally, carbon dioxide from burning fuels is one of the main reasons of global warming,
which is a process that has high potential to change the world’s climate. Carbon dioxide is also
making oceans more acidic, where the population of sea organisms decreases significantly.
There are some other gases such as methane, nitrous oxide, fluorinated gases, which are also
reasons of “Greenhouse effect”, however, carbon dioxide is the main one. In addition, the
concentration of that gas is increasing dramatically every year. Therefore, many studies are
trying to find the best way in order to remove the significant concentration of carbon dioxide
from the atmosphere. However, the best way is to transfer it to another useful compound. This
presentation will mention types of that transformation, mainly into carbon monoxide, because
this substance can be used in fuel and energy productions. Several methods, including water-
gas shift reaction, electrocatalytic, photochemical method, and homogeneous reaction can be
used in order to transform carbon dioxide to carbon monoxide. However, each of them has
advantages and disadvantages, so it is very important to compare them and state the appropriate
way of removing carbon dioxide by converting it into carbon monoxide.
