Abstract: Realizing the effective conversion and utilization of CO 2 is of great significance for alleviating the greenhouse
effect and protecting the ecological environment. A strategy of in situ conversion of CO 2 to carbon-based friction film
without additional energy and catalyst is put forward to enhance the tribological properties of the lubrication system. The
tribological properties of three kinds of olamine solutions after CO 2 absorption were examined by a four-ball friction
testing machine. The experimental results indicated that the friction coefficient of olamine solutions decreased
significantly after CO 2 absorption. The mechanism study revealed that the alkamine solution can react with CO 2 to form
carbamate, and the negatively charged carboxylic acid group in carbamate can be adsorbed on the positively charged
