No. of bitstreams: 0 Previous issue date: 2007-04-25; In this paper we report an experimental and theoretical study based on a periodic density functional investigation into selected compositions of Pb1-x Cax TiO3 (x=0.0, 0.25, 0.50, and 0.75). Based on our findings, we propose that the pseudocubic structure of these perovskites presents a long-range tende...
Salicylic acid boosts the tio2 and zno-mediated photodegradation of paracetamol
Peres, Matheus Ruffo [UNESP]; Pastrello, Bruna [UNESP]; Sambrano, Júlio Ricardo [UNESP]; Morgon, Nelson Henrique; De Souza, Aguinaldo Robinson [UNESP]Made available in DSpace on 2022-04-29T08:32:05Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-01-01; Titanium dioxide (TiO2) and zinc oxide (ZnO) are among the most used catalysts in photodegradation. Paracetamol and salicylic acid are widely used as pharmaceutical drugs. We found that paracetamol is less susceptible to photodegradation compared to salicylic acid. From a chemical perspective, this was ...
