Ti3+-containing titania: Synthesis tactics and photocatalytic performance [PDF]

open access: yes, 2015
Three different synthesis techniques were applied to prepare Ti3+-containing TiO2. The first is a self-doped technique in which TiO2 was reduced in situ at 500 °C by NO and CO gases to produce blue powder (blue titania).

Photocatalytic decomposition of cortisone acetate in aqueous solution [PDF]

open access: yes, 2015
The photocatalytic decomposition of cortisone 21-acetate (CA), a model compound for the commonly used steroid, cortisone, was studied. CA was photocatalytically decomposed in a slurry reactor with the initial rates between 0.11 and 0.46mgL-1min-1 at ...

Facile Formation of Anatase/Rutile TiO2 Nanocomposites with Enhanced Photocatalytic Activity

open access: yesMolecules, 2019
Anatase/rutile mixed-phase TiO2 nanoparticles were synthesized through a simple sol-gel route with further calcination using inexpensive titanium tetrachloride as a titanium source, which effectively reduces the production cost.

A simple strategy to simultaneously improve the lifetime and activity of classical iridium complex for photocatalytic water‐splitting

open access: yesAggregate, 2023
Herein, we design and synthesize a series of oligomers [Ir(ppy)2(dabpy)‐ODPA]n (D1‐n) by copolymerization of [Ir(ppy)2(dabpy)][PF6] (D2) with 4,4′‐Oxydiphthalic anhydride (ODPA), to resolve the problem of simultaneous improvement of stability and ...
