AgBr and Ag3PO4 Coupled with TiO2 as Active Powder Photocatalysts and Glass Coatings

  In this work, different materials based on TiO2 coupled with either AgBr or Ag3PO4 were synthesized. The Ag3PO4(50%)/TiO2 powder photocatalyst prepared by deposition-precipitation method showed higher antimicrobial activity than the bare TiO2 and also than the same coupled powder obtained by sol-gel method. This material achieved 100% E. coli, coliforms, and other enterobacteria elimination.…

New Trends in Nanoclay-Modified Sensors

Nanoclays are widespread materials characterized by a layered structure in the nano-scale range. They have multiple applications in diverse scientific and industrial areas, mainly due to their swelling capacity, cation exchange capacity, and plasticity. Due to the cation exchange capacity, nanoclays can serve as host matrices for the stabilization of several molecules and, thus, they…
