 Context examples 

Photocatalysts such as titania are one way to do this.

(Smog-eating graphene composite reduces atmospheric pollution, University of Cambridge)

Mr. Bhaer was Nick Bottom, and Tina was Titania, a perfect little fairy in his arms.

(Little Women, by Louisa May Alcott)

Now, the researchers demonstrated that a composite of titania and graphene – a two-dimensional form of carbon - has significantly more powerful photodegradation properties than bare titania.

(Smog-eating graphene composite reduces atmospheric pollution, University of Cambridge)

To measure the photodegradation effects, the team tested the new photocatalyst against NOx and recorded a 70% improvement in photocatalytic degradation of nitrogen oxides compared to standard titania.

(Smog-eating graphene composite reduces atmospheric pollution, University of Cambridge)

They found that 40% more rhodamine B was degraded by the graphene-titania composite than by titania alone, in water under UV irradiation.

(Smog-eating graphene composite reduces atmospheric pollution, University of Cambridge)

When titania is exposed to sunlight, it degrades harmful nitrogen oxides and volatile organic compounds present at the surface, oxidising them into inert or harmless products.

(Smog-eating graphene composite reduces atmospheric pollution, University of Cambridge)

By performing liquid-phase exfoliation of graphite – a process that creates graphene – in the presence of titania nanoparticles, using only water and atmospheric pressure, the scientists created the new graphene-titania nanocomposite.

(Smog-eating graphene composite reduces atmospheric pollution, University of Cambridge)

Working in collaboration with the Italcementi HeidelbergCement Group and other partners, the Cambridge scientists developed a photocatalyst that degrades up to 70% more atmospheric nitrogen oxides (NOx) than standard titania nanoparticles in tests on real pollutants.
