The present invention discloses methods for synthesis of 2D non-carbon nanomaterials or 2D complex oxides from materials with complex structure e.g. asphaltenes. It discloses a composition comprising a network of one or more 2D non-carbon nanomaterials having a lattice structure. The lattice structure is selected from an orthorhombic system, monoclinic system, triclinic system. The lattice structure is formed by (ASU)n, where ASU is asymmetric unit and n>=1, where ASU is (TxLyMz) where T is an alkaline metal, L is a chalcogen, O is oxygen, x>=5, y>=2, z>=8. The lattice structure is formed by (ASU)n, where ASU is asymmetric unit and n>=1, where ASU is (TxLyMz H) where T is an alkaline metal, L is a chalcogen, O is oxygen, x>=1, y>=1, z>=5. Examples of the disclosed composition are a network of one or more 2D nanostructures having an asymmetric unit of NaSO.sub.5H or Na.sub.2S.sub.2O.sub.8.
