Analiza hitrosti pretvarjanja srebrovih nanojeder v mikroploščice

diplomsko delo

Kalvin Jelen (Author), Aleš Podgornik (Mentor)

Abstract

Srebrove nanoploščice so posebna morfologija srebra, kot posledica defektov v kristalni strukturi, za katere je značilna oblika trikotnika ali šestkotnika in izredno tanka debelina. Kemijska pretvorba najpogosteje poteka z dodatkom H2O2. Tekom diplomskega dela sem sledil reakciji preko absorbance in posnetkov z elektronsko vrstično mikroskopijo (SEM), na osnovi česar sem opisal odvisnost deleža pretvorbe in morfologije nanoploščic v odvisnosti od dodane količine vodikovega peroksida in naredil računalniški model uporabljenega reaktorja. Reakcija AgNPjev z vodikovim peroksidom v pretočnem reaktorju z membrano poteka lokalizirano na steni membrane. Edina plasmonična barva, ki jo lahko vidimo je modra preden se razbarva in izgine v IR spekter.

Secondary title:	Analysis of the rate of conversion of silver nanocores to microplates
Secondary abstract:	Silver nanoplates are a special morphology of silver, as a result of defects in the crystal structure, which are characterized by a triangular or hexagonal shape and an extremely thin thickness. The chemical conversion most often takes place with the addition of H2O2. During the thesis, I followed the reaction through absorbance and scanning electron microscopy (SEM), based on which I described the dependence of the conversion rate and the morphology of the nanoplates depending on the added amount of hydrogen peroxide and wrote a computer model of the used reactor. Reaction with AgNPs and hydrogen peroxide in a plug flow reactor with a membrane is localized on the wall of the membrane. The only plasmonic color that can be observed is blue before it decolors as it moves to the IR spectre.
