Synthesis of Cerium Oxide Nanoparticles in a Bacterial Nanocellulose Matrix and the Study of Their Oxidizing and Reducing Properties.

ABSTRACT: A soft synthesis of nanoceria with non-stoichiometric composition (33% Ce³⁺/67% Ce⁴⁺) named CeO₂ NPs in bacterial cellulose (BC) matrix in the form of aerogel and hydrogel with controlled CeO₂ NPs content was proposed. The advantage of CeO₂ NPs synthesis in BC is the use of systemic antacid API-trisamine as a precursor, which did not destruct cellulose at room temperature and enabled a reduction in the duration of synthesis and the number of washes. Moreover, this method resulted in the subsequent uniform distribution of CeO₂ NPs in the BC matrix due to cerium (III) nitrate sorption in the BC matrix. CeO₂ NPs (0.1-50.0%) in the BC matrix had a fluorite structure with a size of 3-5 nm; the specific surface area of
