Characterization of TiO2 Modified with Bimetallic Ag/Au Nanoparticles Obtained in Microemulsion System
PublicationFotokatalizatory TiO2 modyfikowane nanocząstkami bimetalicznymi Ag/Au przygotowano metodą mikroemulsyjną w układzie woda/surfaktant/cykloheksan. Aktywność fotokatalityczna próbek Ag/Au-TiO2 oszacowano przez wyznaczenie stopnia degradacji fenolu pod wpływem światła VIS. Fenol został użyty jako model zanieczyszczeń, ponieważ jest substancją niebezpieczną dla środowiska. Najwyższą aktywność w zakresie światła widzialnego wykazała...

Preparation and characterisation of iron substituted Mn1.7Cu1.3-xFexO4 spinel oxides (x = 0, 0.1, 0.3, 0.5)
PublicationSpinel oxides with the general formula Mn1.7Cu1.3-xFexO4 (x= 0, 0.1, 0.3, 0.5) were prepared and evaluated in this work for their properties at high temperatures. The effect of partially substituting Cu by Fe has not been studied so far for this group of materials and is thus evaluated in this work. Mn1.7Cu1.3-xFexO4 powders were synthesised by a soft chemistry process and studied in terms of crystallographic phase analysis, electrical...

XPS measurements of the iron elements covered by chromium
Open Research DataAnticorrosive coatings are an important issue in modern materials engineering. One of the most commonly used, for that coating materials, is chrome. Three metal elements were measured, named as Turcja, WB Tech and Nomet. Names were given according to producer of elements. XPS measurements of the Cr 2p region give an ansver concering on surface chemical...

Enhancement of photocatalytic-based processes by mono- and bimetallic (CuPd) rutile loaded nanoparticles for antibiotic resistance genes and facultative pathogenic bacteria removal
PublicationThe aim of the study was the strong reduction of facultative pathogenic bacteria (FPB), and clinically relevant antibiotic resistance genes (ARGs) from secondary effluent. To evaluate the ARGs removal efficiency comparative study of individual unit processes and combined AOPs has been performed. The present work investigated: i) removal of selected ARGs, namely blaTEM, ermB, qnrS, tetM, five FPB as well as 16S rDNA and the integrase...

Monometallic nanoparticles decorated and rare earth ions doped KTaO3/K2Ta2O6 photocatalysts with enhanced pollutant decomposition and improved H2 generation
PublicationNew, monometallic nanoparticles (MNPs) decorated surface and rare earth (RE) ions doped lattice of perovskite-type (KTaO3)/pyrochlore-type (K2Ta2O6) photocatalysts were successfully prepared by facile hydrothermal incorporation of RE ions into KTaO3/K2Ta2O6 lattices followed by photodeposition of MNPs. The impact of noble metal type (MNPs = Au, Pt, Rh) and rare earth dopant type (RE = Er, Pr) on the physicochemical properties correlated...

Cathodic activation of synthesized highly defective monoclinic hydroxyl‐functionalized ZrO2 nanoparticles for efficient electrochemical production of hydrogen in alkaline media
PublicationThe high electrochemical stability of Zirconia (ZrO2) at high potentials strongly suggested it as an alternative to carbon supports, which experience reduced efficiency due to some corrosion problems particularly during prolonged electrocatalysis activity. However, the use of ZrO2 was limited by its low electrical conductivity and surface area. In this work, we developed a methodology for synthesizing monoclinic ZrO2 NPs with increased...
