Ni nanoparticles supported on SiO2 were decorated with additional SiOx species by impregnation tetraethoxysilane (Si(OEt)4). The combination of electron microscopy, infrared analysis, and density functional theory (DFT) calculations revealed that the SiOx-decoration made surface morphology highly rough step-abundant due to significant stabilization low-coordination-number sites. SiOx-decorated ...

The Cu doped NiO (NiO:Cu) nanoparticles were synthesized by co-precipitation method using NiCl2.6H2O, CuCl2.2H2O for Ni and Cu sources, respectively. Sodium hydroxide has been used as a precipitator agent. Effect of Cu doping agent on the structural and optical properties of nanostructures were characterized by XRD, SEM, AFM, spectrophotometry, FTIR a...

the cu doped nio (nio:cu) nanoparticles were synthesized by co-precipitation method using nicl2.6h2o, cucl2.2h2o for ni and cu sources, respectively. sodium hydroxide has been used as a precipitator agent. effect of cu doping agent on the structural and optical properties of nanostructures were characterized by xrd, sem, afm, spectrophotometry, ftir and vsm techniques. xrd revealed that nio:cu ...

Increasing energy demands, depletion of fossil fuels, and environmental issues have impelled society to choose the pathways renewable clean energy, which motivated scientists engineers develop sustainable, renewable, resources. However, major challenge is implementation low-cost, flexible approaches materials fulfill requirements storage conversion technologies, specifically those involving bat...

We pursue the goal of providing fundamental atomistic understanding of metal oxide and metal sulfide nanostructures supported on metal substrates. Such systems are important as model systems for heterogeneous catalysts and allow better understanding of epitaxial 2D materials, such as MoS2 in contact with a metal. By focusing on what happens on the atomiclevel we can for example evaluate the rol...

Polymer-based composites have been prepared using different concentrations of nanostructured carbons (NCs), produced by catalytic decomposition of methane (CDM). Four carbonaceous nanostructures were produced using different catalysts (with Ni and Fe as active phases), in a rotary bed reactor capable of producing up to 20 g of carbon per hour. The effect of nanostructured carbon on the thermal ...
