| Description
| - Tenké mesoporézní filmy ZnO byly připraveny elektrochemickou metodou využívající eosin Y jako činidla řídícího strukturu. Porézní filmy ZnO byly získány odstraněním eosinu ze struktury. Velikost jejich povrchu a mesoporozita byly charakterizovány fyzikální adsorpcí kryptonu. Parametry depozice, jako její délka a koncentrace eosinu v roztoku, byly optimalizovány, aby byly získány filmy s co možná největším povrchem tak i dobrými mechanickými vlastnostmi. Nejlepší kompromis byl nalezen pro filmy, jejichž tloušťka dosahuje 2 až 3 mikrometry a jež byly připraveny s koncentrací eosinu 50-60 mikroM. Fotodegradace heteropolyaromatického barviva methylenové modře a diazobarviva kongo červeně sloužily jako modelové reakce pro studium fotokatalytické aktivity filmů. Bylo zjištěno, rychlost fotodegradace pro obě barviva dosahuje maxima pro mesoporézní filmy připravené s koncentrací eosinu nad 40 mikroM. (cs)
- Thin mesoporous films of ZnO were prepared by electrochemical deposition using eosin Y as a structure-directing agent. After removal of the eosin from the structure, transparent porous ZnO films were obtained. The porosity and surface area of these films were determined by performing krypton BET measurements. Electrochemical deposition parameters, such as the deposition time and the eosin concentration in the plating bath, were optimized to prepare films with large internal surface areas and good mechanical properties. Eosin concentrations of 50-60 M were found to give the best-quality mesoporous zinc oxide films with film thicknesses ranging from 2 to 3 m. The photodegradations of a heteropolyaromatic dye (methylene blue) and a diazo dye (congo red) served as model reactions to assess the photocatalytic activity of the zinc oxide films. For both dyes, the photodegradation rate reached its maximum for mesoporous films that were prepared with eosin concentrations above 40 M.
