The group covalently modified the surfaces of alumina nanoparticles with an ionic liquid to improve their miscibility with ionic liquids, such as MPII. They used a hybrid gel composite of MPII and the surface-modified nanoparticles as the electrolyte in quasi-solid-state DSSCs. The energy conversion efficiencies were greater when using their modified nanoparticles than when using pristine alumina.
