Effect of formate and methanol on photoreduction/removal of toxic cadmium ions using TiO2 semiconductor as photocatalyst
TL;DR: In this paper, the photoreduction/removal of cadmium was studied at pH 7 using TiO 2 Degussa as photocatalyst, and either formate or methanol as hole scavengers.

Pathways of phenol and benzene photooxidation using TiO2 supported on a zeolite
TL;DR: The use of photocatalysts supported on adsorbents is gaining substantial attention as discussed by the authors, and it is possible to learn in what ways loading TiO2 on an adsorbent high silica zeolite modifies the reactions pathways.

TL;DR: It seemed that many parts of the photocatalysis mechanism depend more on bulk-related properties than do those of hydrophilicity, which can be defined as an interfacial (surface) or near-surface-restricted process.

Comparison of the efficiency of immobilized and suspended systems in photocatalytic degradation
M.F.J. Dijkstra,A. Michorius,H. Buwalda,H.J. Panneman,Jozef G. M. Winkelman,A.A.C.M. Beenackers +5 more
TL;DR: The addition of oxygen to the immobilized system appeared to increase the quantum yield with a factor 4, whereas the addition ofoxy to the suspended system hardly had any effect.
