TITANIUM DIOXIDE PHOTOCATALYSTS FOR REVERSE OSMOSIS CONCENTRATE RECOVERY

摘要

Disclosed herein is a composition comprising: TiO2 nanocrystals in the form of agglomerates and/or aggregates; and an anionic species associated with the TiO2 agglomerates/aggregates, wherein the diameter of the TiO2 agglomerates/aggregates is from 0.02 μm to 5.0 μm; the diameter of the TiO2 nanocrystals is from 4 to 70 nm; and the BET surface area of the composition is from 6 to 250 g/m2. There is also disclosed a method for making said compositions and uses thereof.
