Global warming persuades researchers to improve the effectiveness of renewable energy technologies, such as H2 production by methane steam reforming (MSR) an endothermic process. Herein, a nanocatalyst based on open-cell nickel foam 40 (pore per inch) with high thermal conductivity was prepared. The synthesized chemical stepwise synthesis approach, pre-treatment, pulsed electrocodeposition Ni-A...
<p>In this research, we have described a facile and user-friendly protocol for the formation of 2((1H-Indole-3yl)(Phenyl)methyl)malononitrile derivatives using recoverable efficient TiO2 nanocatalyst. This is simple incredibly synthesis novel derivatives. Nanoscale used as catalyst. Since TiO<sub>2 </sub>has more surface area easily binds with active site reactive molecule ini...
Molecular dynamics simulation of PEMFC cathodes based on ternary Pt70Pd15Au15 and Pt50Pd25Au25 nanocatalysts dispersed on carbon indicate systematic Au segregation from the particle bulk to the surface, leading to an Au layer coating the cluster surface and to the spontaneous formation of a Pt@Pd@Au core-shell structure. For Au content below 25at%, surface PtxPdy active sites are available for ...
In this study, the effect of Fe3O4-coated graphene as a nanocatalyst on the degradation kinetics of Ammonium Perchlorate and Glysydyl Azide Polymer (AP/GAP) composite propellants is investigated in order to modify and improve the burning rate of propellants. The SEM-EDX and EDX-Mapping surface analysis methods were used for structural and morphological study of the propellant containing nanoca...
Immobilizing of zero-valent iron in mono- and bi-metallic systems on the bentonite clay surface as new nanocatalyst were synthesized and used to degrade model acidic dyes from aqueous media. The Fourier-transform infrared spectroscopy, scanning electron microscopy-energy dispersive X-ray spectroscopy, transmission electron microscopy, X-ray diffraction, and Brunauer-Emmett-Teller analysis were ...
