Using graphite intercalation compounds for producing exfoliated graphite-amorphous carbon-TiO2 composites

A new method for producing the TiO2-exfoliated graphite-amorphous carbon composites was developed. It involves anatase-type TiO2, residual graphite hydrosulfate and sucrose as starting materials and makes it easier to produce such floating composites on a large scale. The composites are promising for water purification as they couple the buoyancy of exfoliated graphite with the sorption capacity of amorphous carbon and the photocatalytic activity of anatase.
