- 2020Combined effect between PVP and glass wool for improvement of the photocatalytic activity under visible light of bismuth (III) oxyhalide and access to α-Bi2O3-BiOI-BiOBr ; Improvement of the photocatalytic efficiency of BiOI/BiOBr composite have been obtained by a combined effectbetween a structuring agent like polyvinylpyrrolidone (PVP) and glass wool (GW) introduced during theirsynthesis by solvothermal (STP) or hydrothermal (HTP) process. The photocatalysts were characterized by XRD,SEM, XPS, UV–Visible DRS, BET and EDX and their activity tested in the photo-degradation of Rhodamine B(RhB) under visible light. Photocatalyst prepared by STP have higher photocatalytic efficiency than those preparedby HTP, moreover, the presence of PVP and GW greatly improve this efficiency, a total discoloration ofRhB solution (20 mg L−1) being obtained after 18 min. The photodegradation mechanism has been proposed bythe identification of the radical species responsible for the degradation. Indeed, two radical species have beenidentified for the catalyst prepared without GW, most of them the hole (h+) and moderately super oxide anion(O2· ). Differently, for the catalyst prepared with GW, three species have been identified, h+ being the mainspecies with a moderate contribution of the hydroxyl radical (HO%) and O2· .citations

Influence of <scp>TiO<sub>2</sub></scp> nanofiller geometry on the rheological and optical properties of poly(acrylic acid)‐based nanocomposite hydrogels
Abstract
<jats:title>Abstract</jats:title><jats:p>The properties of macroscopic polymer nanocomposites are highly dependent on the nanoparticle–polymer interfacial region, which varies with the morphology of the nanoparticles. Herein, we used TiO<jats:sub>2</jats:sub> nanofillers with very low aspect ratio, the same chemical composition, and surface functions, but different geometries (nanospheres and nanoplates) dispersed in a poly(acrylic acid) matrix to analyze the influence of the nanoparticle geometry on the properties of nanocomposite hydrogels. The geometry was found to affect the swelling and rheological properties of the nanocomposite polymers. Particularly, the yield strain (from 25% to 130%), modulus (from 17,500 to 25,000 Pa), and brittleness of nanoplates based nanocomposite increased more significantly. Finite‐difference time‐domain simulations demonstrated that nanoplates increased the wavelength of the absorption maxima (224 nm for NS to 240 nm for NP) and charge distribution. The results obtained in this research indicate that the nanofiller shape markedly influences the rheological properties of the nanocomposite polymers, opening the door to further research focused on polymer–nanofiller interactions, and their effect on the macroscopic properties of the nanocomposites.</jats:p>
