Abstract
X6Al2HT hydrotalcites, where X represents Fe, Cu, Zn, Ni, Co, Mn or Mg, were synthesized as precursors of catalysts for the toluene and CO total oxidation reactions. Specific area, Fourier transformed infrared spectroscopy analysis, XRD measurements and Thermal analysis of these dried solids were performed. After calcination at 500 °C, different mixed oxides were obtained. The structural analysis (XRD, FTIR) and specific areas of these solids were done. Concerning the total oxidation of toluene, the best activity is obtained with Mn6Al2HT catalyst with T50 at 249 °C. X6Al2 nano‐oxides synthesized using hydrotalcite‐type solids as precursors, are then very promising candidates for an utilisation as CO and VOC oxidation catalysts. The nature of bivalent cation in these compounds is essential for the efficacy of the catalyst.
X6Al2HT hydrotalcites, with X = Fe, Cu, Zn, Ni, Co, Mn or Mg, were synthesized as precursors of catalysts for the toluene and CO total oxidation reactions. The catalytic activity can be established is following order: Mn6Al2HT500 > Co6Al2HT500 = Cu6Al2HT500 > Fe6Al2HT500 > Ni6Al2HT500 >> Zn6Al2HT500 > Mg6Al2HT500.

Vesicle‐Mediated Growth of Tubular Branches and Centimeter‐Long Microtubes from a Single Molecule
Abstract The mechanism by which small molecules assemble into microscale tubular structures in aqueous solution remains poorly understood, particularly when the initial building blocks are non‐amphiphilic molecules and no surfactant is used. It is here shown how a subnanometric molecule ... more
The image illustrates a natural phenomenon of droplet formation caused by the condensation of vapor on a nonwettable surface at temperature below the dew point. Real‐time observing the light scattered from the droplets may lead to a new mechanism for vapor sensing. However, the dew point ... more
NO is a key vasodilator in mammalian cardiovascular systems and has been shown to sensitize tissue to γ‐radiation. However, photochemical NO precursors that can be activated by these NIR wavelengths are extremely limited. G. D. Stucky, D. Zhao, P. C. Ford, F. Zhang and co‐workers have ad ... more
Bioengineers Succeed in Producing Plastic Without the use of Fossil Fuels
A team of pioneering South Korean scientists have succeeded in producing the polymers used for everyday plastics through bioengineering, rather than through the use of fossil fuel based chemicals. This groundbreaking research, which may now allow for the production of environmentally consci ... more
In the past, restoration of paintings and other old artwork often involved application of acrylic resins to consolidate and protect them. One of the most important tasks for modern restorers is thus to remove these layers, because it turns out that acrylic resins not only drastically change ... more
Is trash the solution to tackling climate change?
Converting the trash that fills the world's landfills into biofuel may be the answer to both the growing energy crisis and to tackling carbon emissions, claim scientists in Singapore and Switzerland. New research published in Global Change Biology: Bioenergy, reveals how replacing gasoline ... more
