Abstract Mercury pollution threatens the environment and human health across globe. This neurotoxic substance is encountered in artisanal gold mining, coal combustion, oil gas refining, waste incineration, chloralkali plant operation, metallurgy, areas of agriculture which mercury‐rich fungicides are used. Thousands tonnes mercury emitted annually through these activities. With Minamata Convention on entering force this year, increasing regulation imminent. It therefore critical to provide...
Surface defects of Fe-doped CeO<sub>2</sub> nanorods were found to be active sites for increasing peroxidase mimetic activity.
The developed ceria–zirconia modified MnO<sub>x</sub> catalysts were found to exhibit enhanced Hg<sup>0</sup> oxidation and removal performance.
Large-scale synthesis of O-deficient Cu<sub>2</sub>O with outstanding visible photoactivity is shown.
In the present work, nanowire morphologies of α-MnO2, cobalt monodoped Cu and Co bidoped Ni α-MnO2 samples were prepared by a facile hydrothermal synthesis. The structural, morphological, surface, redox properties all as-prepared investigated various characterization techniques, namely, scanning electron microscopy (SEM), transmission high resolution (TEM HR-TEM), powder X-ray diffraction (XRD), N2 sorption surface area measurements, photoelectron spectroscopy (XPS),...
Spectrally-selective monitoring of ultraviolet radiations (UVR) is paramount importance across diverse fields, including effective excessive solar exposure. Current UV sensors cannot differentiate between UVA, B, and C, each which has a remarkably different impact on human health. Here we show spectrally selective colorimetric UVR by developing photoelectrochromic ink that consists multi-redox polyoxometalate an e- donor. We combine this with simple components such as filter paper...
In recent years, the development of artificial nanostructured enzymes has received enormous interest in nanobiotechnology due to their advantages over natural enzymes. present work, different amounts (5, 10, and 20 wt%) Co3O4 nanoparticle decorated CeO2 hybrid flower-like microspheres (Co3O4@CeO2) have been investigated for peroxidase-like activity it was found that 10 wt% Co3O4@CeO2 exhibited excellent catalytic oxidation 3,3',5,5'-tetramethylbenzidine (TMB) substrate presence H2O2. The...
Transition metal doped ceria nanorods exhibit a better CO oxidation activity at lower temperatures.
Mn and Fe codoped ceria-based solid solutions are effective catalysts for Hg<sup>0</sup> removal at low flue gas temperatures.
Global temperature has risen >1 °C since the preindustrial era, resulting in well-documented adverse climate impacts including extreme weather (floods, droughts, storms, and heat waves), a rise sea level accompanying melting polar glacial ice, disrupted crop growth. These changes are closely correlated with anthropogenic greenhouse gas emissions, predominantly arising from combustion of nonrenewable fossil fuels. Lignin derived lignocellulose is second most abundant biopolymer on Earth, rich...
The sustainable synthesis of high-quality graphene sheets is one the hottest and most inspiring topics in fields science engineering. While oxide (GO) chemical reduction method widely used to synthesize sheets, this route commonly includes highly hazardous reducing agents that are dangerous both humans environment. In context, here we describe a green, effective, economical strategy for soluble by using Eucalyptus polyphenol solution obtained from bark extract. ability compounds present...
The presence of oxygen vacancies and synergetic interaction between Ce Mn were responsible for superior Hg<sup>0</sup> oxidation performance CeO<sub>2</sub>–MnO<sub>x</sub> compared to pure CeO<sub>2</sub> MnO<sub>x</sub>.
The catalytic behavior of various CeO2-based solid solutions, namely, Ce1−xTMxO2−δ (TM = Mn, Fe, or Zr) and Ce1−xRExO2−δ (RE Pr, La, Sm) was studied for the removal elemental mercury (Hg0) from coal-derived flue gas by oxidation (Hg0 → Hg2+). investigated catalysts were synthesized a coprecipitation method characterized techniques, X-ray diffraction (XRD), Raman spectroscopy (RS), high-resolution electron microscopy (HREM), Brunauer–Emmett–Teller (BET) surface area, photoelectron (XPS),...
