• Resorcinol–formaldehyde (RF) and graphene oxide (GO) aerogels have found a variety of applications owing to their excellent properties and remarkable flexibility. However, the macroscopic and controllable synthesis of their composite gels is still a great challenge. By using GO sheets as template skeletons and metal ions (Co2+, Ni2+, or Ca2+) as catalysts and linkers, the first low‐temperature scalable strategy for the synthesis of a new kind of RF–GO composite gel with tunable densities and mechanical properties was developed. The aerogels can tolerate a strain as high as 80 % and quickly recover their original morphology after the compression has been released. Owing to their high compressibility, the gels might find applications in various areas, for example, as adsorbents for the removal of dye pollutants and in oil‐spill cleanup. Eine Komposit‐Aerogel aus Resorcin/Formaldehyd und Graphenoxid (GO) wurde unter Verwendung von GO‐Schichten als Templaten und Metallionen (Co2+, Ni2+ oder Ca2+) als Katalysatoren und Linkern synthetisiert. Diese Aerogele können um bis zu 80 % komprimiert werden und schnell in ihre ursprüngliche Form zurückkehren.
