A simple and inexpensive approach is used to coat metal oxide surfaces (SBA‐15) with thin films of carbon. These carbon films provide improved hydrothermal stability to oxides, such as silica and alumina, which are not otherwise stable at elevated temperatures in the presence of liquid water (see picture). Furthermore, the carbon film changes the surface chemistry of the support.
