| Description
| - Vliv velikosti/tvaru nanokrystalů na elektrokatalytické chování nanokrystalických oxidů byl demonstrován na elektrodách připravených z nanokrystalického RuO2 syntetizovaného sol-gel metodou. Velikost částic připravených vzorků RuO2 se pohybovala mezi 15-40nm. Nezávisle na velikosti částic byly nanokrystaly pravidelného tvaru s polygonální prismatickou částí uzavřenou dvěmi pyramidami. Prismatická část obsahovala v případě menších částic (d<20) (110) a (100) orientované stěny zatímco větší (d>20) nanokrystaly (110), (100) a (140) stěny. Pyramidální část byla tvořena (101) orientovanými stěnami. Aktivita nanokrystalů RuO2 vzhledem k reakci vylučováni kyslíku se snižuje s rostoucí velikostí částic, zatímco velikost a tvar částic nemají vliv na aktivitu vzhledem k vylučování chlóru. Pozorovaná tendence naznačuje, že reakce vylučování kyslíku je významě ovlivněna hranami krystalů, zatímco produkce chlóru probíhá hlavně na stěnách krystalů. (cs)
- The effect of nanocrystal size/shape on the electrocatalytic behavior of nanocrystalline oxide electrodes was demonstrated on electrodes based on sol-gel-prepared RuO2 materials. The typical particle size ranged between 15 and 40 nm. Regardless of the particle size, the nanocrystals were of isometric shape with polygonal prismatic part capped with two pyramids. The prismatic part of the nanocrystals featured {110}- and {100}-oriented faces in the case of small nanocrystals (d < 20 nm) and {110}, {100} and {140} in the case of bigger nanocrystals (d > 20 nm). The pyramidal parts were formed by {101}-oriented faces. The activity of the RuO2 nanocrystals towards oxygen evolution reaction decreases with increasing particle size; the activity towards chlorine evolution is insensitive to the particle size/shape. The observed tendency indicates that the oxygen evolution is significantly affected by the crystal edges while chlorine evolution reaction proceeds mainly on crystal faces.
