Influence of Pr3+ doping on the synthesis of colloidal sols and nanoparticulate TiO2 xerogels and their photocatalytic activity

Autor: Angel L. Ortiz, Karent J. Duarte, D. Fabio Mercado, Luz M. Ballesteros-Rueda, María T. Colomer

Publikováno v: Materials Characterization. 182:111536

Newtonian nanoparticulate TiO2 sols without and with Pr3+ doping (0.5, 1, 2, 3, 5, and 10 mol%) were synthesized by the aqueous colloidal sol-gel method, next elucidating that the Pr3+ doping increasingly retards their peptization while makes them mo

Publikováno v: Journal of Cleaner Production. 289:125793

Three low-cost and abundant agro-industrial residues have been used as hexavalent chromium adsorbents. Blackberry residues and spent ground coffee were the most efficient adsorbents with 10.6 ± 5.9 and 9.7 ± 3.0 mg g−1 maximum adsorption uptake,
