Titanium dioxide modified with 3 wt% La was prepared via a green freeze-casting method, and its photocatalytic activity was tested in terms of its ability to degrade 4-chlorophenol (4-CP) and remove total organic carbon (TOC). Under annealing conditi

Publikováno v: Electrochimica Acta. 321:134685

Novel facile synthetic procedure is developed to prepare thin (tens of nm) films of TiO2 (rutile) from thin titanium layers on different substrates. The ‘electrochemical’ Tauc plot provides more coherent values of the band-gap than the correspond

Polarography and Voltammetry of Mixed Titanium(IV) Oxide/Iron(III) Oxide Colloids

Autor: Miroslava Struplova-Bartackova, Jaromir Jirkovsky, Michael Heyrovsky

Publikováno v: Langmuir. 11:4309-4312

The polarographic and voltammetric study of mixed titanium oxide/iron oxide colloids shows that the composition and presumably also the structure of the colloidal particles varies with their size. Iron seems to prevail in the smallest particles ; tit
