Hollow PtAg alloy nanospheres were synthesized via galvanic replacement reaction between silver nanoparticles and K2PtCl4 at 60 C. Their morphology, composition and structure were characterized by UV-vis, XRD, TEM, HRTEM, SAED, EDX and XPS. It was found that the shell thickness and roughness could be controlled by varying the amount of Pt precursor solutions. Compared with commercially availabl...

A novel dynamic soft template solution route has been developed for the preparation of micrometre-sized In2S3 half-shells, assembled by fine nanoparticles. This novel half-shell nanostructure was characterized by electron microscopes, x-ray diffraction (XRD), x-ray photoelectron (XPS), and optical spectroscopes. The catalytic property in the electro-oxidation of the nitric oxide (NO) of the hal...

In order to reduce the operating temperature of solid oxide fuel cells (SOFCs), anodesupported cells incorporating thin film (~10 μm) electrolytes in conjunction with anode/electrolyte and cathode/electrolyte interlayers were studied. Anode supported button cells were prepared through a conventional approach and were analyzed via Scanning Electron Microscopy (SEM), Polarization, and Electrochem...

In the rapidly developing areas of nanotechnology, nano-scale materials as heterogeneous catalysts in the synthesis of organic molecules have gotten more and more attention. In this review, we will summarize the synthesis of several new types of noble metal nanostructures (FePt@Cu nanowires, Pt@Fe₂O₃ nanowires and bimetallic Pt@Ir nanocomplexes; Pt-Au heterostructures, Au-Pt bimetallic nanocomp...

The analysis of various parameters of metal oxides and the search of criteria, which could be used during material selection for solid-state gas sensor pplications, were the main objectives of this review. For these purposes the correlation between electro-physical (band gap, electroconductivity, ype of conductivity, oxygen diffusion), thermodynamic, surface, electronic, structural properties, ...

Transition metal carbides/nitrides (MXenes) with eccentric properties are emerging 2D nanomaterials intriguing applications in the photo and electro-catalytic water splitting (Wsp). MXenes have a regular planer structure large specific surface area (SSA), excellent hydrophilicity, metallic conductivity, wide range of functionalities termination groups, making them promising candidate for long-t...

In recent years, combinatorial methods have attracted a great deal of attention. Among them, sono-combining techniques have shown a significant potential as an economic technology applicable and environment-friendly technology for wastewater treatment. In this study, Sono Electrochemical SE, Sono Photo Electrochemical SPE and Sono Photo Electro Catalytic SPEC techniques were investigated for de...
