Enhanced Electrochemical Performances of Heterostructures Based on the Colloidal Association of Graphene Oxide and Titanium Disulfide Nanosheets.

Due to the large proliferation of electrical devices combined with the ecological transition for carbon neutrality in various modern countries, the demand for compact and efficient portable energy sources is continuously increasing. In this research work, we have developed electrochemical energy storage heterostructures based on graphene oxides (GOs) and titanium disulfide (TiS) nanosheets of different lateral sizes through a facile colloidal association thanks to the opposite electric charges of the two types of nanosheets. Large GO (LGO) served as a template system to organize TiS nanosheets at different loadings, of which incorporation prevented any restacking of the layered graphitic structure.
