Abstract
A process is disclosed comprising, providing a source of graphene, providing a particulate material, dispersing a mixture of the source of graphene and the particulate material in a first dispersion fluid to form a dispersion mixture, and providing a source of a base in the first dispersion fluid, thereby causing the source of graphene and particulate material in the dispersion mixture to interact forming a composite. The particulate material is preferably titanium dioxide comprising anatase and/or rutile which provides an effective photocatalytic composite. Also disclosed is apparatus to remove pollutants from fluids using the photocatalytically active material.
Claims13
A process for producing a flocculated composite product, the process comprising:
- a) providing a source of graphene, wherein the source of graphene is selected from pristine graphene and partially oxidised graphene;
- b) providing a particulate material, wherein the particulate material is a metal oxide,
- c) dispersing a mixture of the source of graphene and the particulate material in a first dispersion fluid to form a dispersion mixture, and
- d) providing a source of a base which comprises a source of hydroxide ions in the first dispersion fluid, wherein the source of hydroxide ions is provided at an amount of 0.5 millimoles to 20 millimoles per 10 g of the metal oxide;
- wherein the addition of the source of a base causes the source of graphene and particulate material in the dispersion mixture to interact forming a flocculated composite product;
- and wherein the process is performed in the absence of a surfactant.
