The morphology of graphene‐based foams can be engineered by reinforcing them with nanocrystalline zirconia, thus improving their oil‐adsorption capacity; This can be observed experimentally and explained theoretically. Low zirconia fractions yield flaky microstructures where zirconia nanoparticles arrest propagating cracks. Higher zirconia concentrations possess a mesh‐like interconnected structure where the degree of coiling is dependant on the local zirconia content.
