Бұл жұмыста титан диоксидінің (TNR) наноөзекшелеріндегі күміс нанобөлшектерінің концентрациясының олардың фотокаталитикалық белсенділігіне әсерін зерттеу нәтижелері келтірілген. Рутил құрылымы бар TNR гидротермиялық синтез әдісімен алынды. Өтпелі металл күміс тұзының (AgNO3) зат мөлшерімен өзгеріп, TNR бетіндегі химиялық тотықсыздану арқылы әртүрлі концентрациядағы Ag нанобөлшектері алынды. Беттік морфология мен ЭДА зерттеулері Ag нанобөлшектерінің біркелкі таралғанын және TNR бетіне бекітілгенін көрсетті. Үлгілердің фотокаталитикалық белсенділігі пленка бетінің бірлігінен алынған фототок мөлшері және ксенон шамының жарық көзімен бетті жарықтандыру кезінде метилен көк бояғыштың фотодеградациясы бойынша бағаланды.
