Abstract
Proučavan je utjecaj jednovalentnog iona litija i trovalentnog iona cerija na tijek kristalizacije i fotokatalitičku aktivnost perovskita. Kodopirani perovskit, Ca1-2x LixCexTiO3 (x=0,00-0,04) pripravljen je sol gel procesom te termičkom obradom pri 500 °C u trajanju od 2 sata. Tijek kristalizacije, fazni sastav, morfologija i kemijski sastav pripremljenih uzoraka ispitani su rendgenskom difrakcijom praha (XRD), infracrvenom spektroskopijom s Fourierovom transformacijom (FTIR-ATR), simultanom termičkom analizom (STA), energijski razlučujućom rendgenskom spektroskopijom (EDS) te elektronskim pretražnim mikroskopom (SEM). Učinkovitost fotokatalitičke razgradnje metilenskog plavila (MB) praćena je mjerenjem apsorbancije UV-VIS spektroskopijom te je utvrđeno da je najveća za uzorak s najvećim udjelom dopanata.
Abstract (english)
In this paper the effects of monovalent lithium and trivalent cerium ion codoping on crystallization path and photocatalytic activity of CaTiO3 were investigated. Codoped perovskite Ca1-2x LixCexTiO3 (x=0,00-0,04) powder were prepared by sol–gel method followed by thermal treatment at 500 °C for 2 h. Crystallization path, phase composition, morphology and chemical composition of the prepared samples were characterized by various methods such as X-ray diffraction (XRD), scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FTIR), simultaneous thermal analysis (STA), electron dispersive spectroscopy (EDS) and UV–vis spectroscopy. Photocatalytic activity of CaTiO3 was investigated via measuring the photodegradation of methylene blue under UV light irradiation and it was established that activity is greatest for sample with greatest rate of dopants.
