A new route for preparation of TiO2-mounted activated carbon
TL;DR: In this article, a TiO 2 -mounted activated carbon was prepared by the precipitation of tetraisopropyl orthotitanate on the surface of poly(vinyl butyral) (PVB) and subsequent carbonization to different final temperatures from 700 to 900°C under a flow of carbon dioxide.

Preparation of visible light active S-doped TiO2 photocatalysts and their photocatalytic activities.
TL;DR: Chemically modified titanium dioxide photocatalysts in which S (S4+) substitutes for some of the lattice titanium atoms are synthesized, which show strong absorption for visible light and high activities for degradation of 2-propanol in aqueous solution and partial oxidation of adamantane in acetonitrile under irradiation at wavelengths longer than 440 nm.

Effect of Particle Size and Background Natural Organics on the Adsorption Efficiency of PAC
TL;DR: In this article, the authors evaluated the importance of particle size and background organ and developed a procedure to predict the performance of powder activated carbon (PAC) and showed that PAC performance can be significantly improved by using smaller-size PAC but that the rate of adsorption and PAC capacity are markedly reduced when naturally occurring humic substances are present in the groundwater.
