The properties of water are of importance in many scientific disciplines such as chemistry, biology, geology, nanotechnology, and materials technology. Moreover, the adsorption of water on activated carbon (AC) is an important topic in many different areas of science and technology because water is the most common solvent in nature. The adsorption and phase behavior of polar fluids in carbon pores has been studied extensively, but our understanding of the adsorption of water on carbonaceous materials is still incomplete (1, 2, 3, 4).

In recent years, a number of experimental and simulation studies of adsorption of water in pores have appeared in the literature. Some studies have assumed that the adsorption behavior of water in graphite pores is hydrophobic. Although principally hydrophobic adsorbents may contain significant numbers of adsorption centers that can interact with water, it is generally believed that the combination of weak carbon–water dispersive attractions and strong water–water associative interactions are responsible for the complex behavior of water confined in carbonaceous pores.
