The influence of the morphology of 1D TiO2 nanostructures on photogeneration of reactive oxygen species and enhanced photocatalytic activity

Ultrasound irradiation as an effective tool in synthesis of the slag-based catalysts for carboxymethylation

“…Application of the high synthesis temperature in the case of water treatment leads to formation not only of needle shape, but also round shape crystals with an average size 128 ± 42 nm ( Table A3 ) typically observed in the case of hydrothermal synthesis of steel slag [9] , [10] . A survey of literature shows that the assignment of this type of crystals is controversial, as they can be attributed to different phases – TiO 2 (anatase [31] , [32] or rutile [32] ), Fe 2 O 3 [33] , [34] or CaCO 3 [30] , [35] . Moreover, presence of the numerous impurities complicates the process of phase identifications even further, as illustrated for Fe 2 O 3 doped with inorganic cations [33] .…”

Chromium Speciation in Zirconium‐Based Metal–Organic Frameworks for Environmental Remediation

“…[44][45][46][47][48] Generally speaking, two approaches have been applied in Zr based MOFs in order to endow them of ad ual adsorption/ionreductivef unctionality:i )the organic pillars decoration with electron-donor groups that trigger the chromium reduction [49][50][51] (Scheme 1C)a nd ii)the use of photoactive building blockst hat are able to generate radicals to trigger the Cr VI to Cr III transformation. [21,[52][53][54][55][56] Therefore, depending on the chemical information encoded within the UiO-66 framework, its Cr VI adsorption and, more specifically,i ts ion-reductive capacity can be regulated to different extents. This modulation of as pecific chemicalp roperty enables the after-operation study of diverse Cr speciation scenarios (Scheme 1B,C ).…”

Antimicrobial TiO2 nanocomposite coatings for surfaces, dental and orthopaedic implants

“…A specialized reusable filter surface with photocatalytic TiO 2 nanowires (TiO 2 NWs) was developed to inactive the airborne pathogens [1] . TiO 2 NWs offered an improved photocatalytic efficiency owing to the high surface to volume ratio for ROSs generation [72] . The schematic of ROSs generation on TiO 2 NWs filter is displayed in Figure.…”
