Description of the Cover Picture

The cover picture is taken from the article“Mechanism of K/Ni etching for biochar-H_(2)O gasification”.In the process of biomass catalytic gasification,K and Ni play a very important role.Due to the difficulty in analyzing the catalytic mechanism of the catalyst from an atomic perspective in the experiment,density functional theory was used to analyze the catalytic gasification reactor between biochar and water in the biomass gasification process.
