Abstract
U ovom radu su okarakterisani novi elektrodni materijali na bazi perovskita za detekciju 4-nitrofenola. Mešoviti oksidi perovskitnog tipa hemijske formule La0.7Sr0.3Cr1-XRuXO3 (X= 0; 0.05) su sintetisani konvencionalnim keramičkim postupkom. Rezultati rendgenske difrakcione analize su pokazali da je sintetizovani sistem dvofazan, i da pored dominantne perovskitne faze sadrži udeo stroncijum hromata. Ugljenična pasta elektroda je modifikovana sintetisanim perovskitima kako bi se ispitala njihova elektroaktivnost. Tako dobijene elektrode su primenjene za oksido-redukciju 4-nitrofenola u kiseloj sredini. Prisustvo rutenijuma u perovskitnoj strukturi dovodi do povećane elektrohemijske aktivnosti elektrode za redukciju 4-nitrofenola.
In this paper new perovskite-based electrode materialsfor 4-nitrophenol detection were characterized. Mixed oxides of pereovskite type with general molecular formula La0.7Sr0.3Cr1-XRuX03 (X= 0; 0.05) were synthesized by ceramic procedure. The results of X-ray diffraction analysis showed that synthesized system has two-phase structure, including strontium chromate phase beside dominant perovskite phase. Carbon paste electrode was modified with synthsized perovskites in order to study their electrochemical activity. Electrode prepared innn such manner were used for oxido-reduction of 4-nitrophenol in acidic media. The addition of ruthenium to perovskite structure lead to increased electrochemical activity of this electrode for reduction of 4-nitrophenol.
