Abstract

Przedmiotem zgłoszenia jest sposób syntezy nanocząstek tlenkowych (MxOy) o właściwościach półprzewodnikowych, gdzie M to metal, znajdujące zastosowanie w wielu gałęziach gospodarki, takich jak: ogniwa słoneczne, nanourządzenia elektroniczne, nanourządzenia emitujące światło, falowody, technologie laserowe, biosensory, katalizatory. Przedmiotowy sposób syntezy nanocząstek tlenkowych (MxOy) z zastosowaniem czynników biologicznych, które stanowią drożdże, korzystnie Saccharomyces cerevisiae, których hodowle, w trakcie jego realizacji, doprowadza się do pH od 2 do 10, charakteryzuje się tym, że w pierwszym etapie prowadzi się hodowle drożdży, w płynnym podłożu doprowadzając ją do wymaganego pH, po czym dodaje się do niej stałą sól metalu - Fe lub Cr lub Mn lub Co lub Cu lub Ni lub Ti lub Zr w ilości 0,05 do 0,1 milimola/litr i prowadzi się reakcję stale mieszając, do momentu zaobserwowania pojawienia się osadu o odpowiednim kolorze. Mieszaninę reakcyjną suszy się i praży się w temperaturze od 100 do 600°C.The subject of the application is a method for the synthesis of oxide nanoparticles (MxOy) with semiconductor properties, where M is a metal, which is used in many branches of the economy, such as: solar cells, electronic nanodevices, light-emitting nanodevices, waveguides, laser technologies, biosensors, catalysts. The subject method of synthesis of oxide nanoparticles (MxOy) using biological agents, which are yeast, preferably Saccharomyces cerevisiae, whose cultures are adjusted to a pH of 2 to 10 during its implementation, characterized by the fact that yeast is grown in the first stage in a liquid medium, bringing it to the required pH, after which a solid metal salt - Fe or Cr or Mn or Co or Cu or Ni or Ti or Zr is added in an amount of 0.05 to 0.1 millimoles / liter and carried out the reaction stirring constantly until the appearance of a precipitate of the appropriate color. The reaction mixture is dried and calcined at 100 to 600 ° C.
