A resistive sensor based on films of carbon gel-TiO2 nanocomposites prepared with different percentages TiO2 by a sol-gel process, was developed to determine ammonia gas. thin film dispersed in poly(vinylidenfluoride) and deposited glass slides containing silver electrodes are used as NH3 sensor. The resistance the at potential difference 1.0 V determined presence NH3, CO2, C2H5OH, CH3OH, C4H10O C4H8O2 gases concentrations range 0–1000 ppm. response expressed sensitivity -Response (%)-...
Undoped metal-free graphene oxide (GO) materials prepared by either a modified Hummers’ (GO-H) or Brodie’s (GO-B) method were tested as photocatalysts in aqueous solution for the oxidative conversion of phenol. In dark, adsorptive capacity GO-B towards phenol (~35%) was higher than that GO-H (~15%). Upon near-UV/Vis irradiation, able to remove 21% after 180 min, mostly through adsorption. On other hand, using less energetic visible removed much 95% just 90 min. By thorough characterization...
Graphitic carbon nitride (g-C3N4) was synthetized by a one-step thermal method from different N-rich precursors, namely melamine, dicyandiamide, urea, thiourea and cyanamide. The structure, optical physicochemical properties of g-C3N4 materials were studied transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) Raman spectroscopy, among others. Both melamine dicyandiamide provided less porous structure composed large flake sheets, whereas urea favoured small flat...
A series of adsorbents (activated carbons, ACs) were synthesized by physical and chemical activation olive stones (OS) their textural characteristics determined complementary techniques such as N
Microcystin-LR (MC-LR) is the most common and toxic variant of group microcystins (MCs) produced during formation harmful cyanobacterial blooms. Geosmin (GSM) 2-methylisoborneol (MIB) may also be blooms can taint water causing undesirable taste odor. The photocatalytic degradation MC-LR, GSM, MIB in under both UV-A solar light presence reduced graphene oxide–TiO2 composite (GO–TiO2) was studied. Two commercially available TiO2 materials (Degussa P25 Kronos) a reference material prepared...
