摘要
Continuous growth of atmospheric CO2 concentration believed to be the major reason for "greenhouse effect", has become a global environmental issue in recent years. CO2 reduction is a challenge not only for the survival of human society, but also for the development of geosciences and technology. Understanding CO2 fluid-rock interaction is the key to successful geological storage of CO2, because of its effects on CO2 injection efficiency, and storage capacity, efficiency, safety and stability of the reservoir. Nanoscale materials have extraordinary properties with their abnormally huge amount of surface atoms and surface energy. CO2 fluid-rock interaction has multi-scale effect, with much higher rate and efficiency at nanoscale than those at other scales, due to substantial differences in surface atoms and surface energy.
