Abstract

Metal or metal oxide nanoparticles possess unique features compared to equivalent larger-scale materials. In this paper we present the synthesis of grafted titania with phosphonic acids, their characterization and an extended non-isothermal kinetic study. The obtained results show that there in no significant difference between acids and esters in grafting reaction. The phosphorus content wary between 0.9 and 1.80% and is comparable with literature data. IR and AFM studies confirmed the formation of grafted titania. Extended non-isothermal kinetic study using different methods confirmed the complexity of thermooxidative degradation processes in non-isothermal conditions.
