This procedure has developed the use of TiO2 nanoparticles as an environmentally friendly and highly efficient heterogenous nanocatalyst for the eco-safe, facile and one-pot three-component Biginelli synthesis of biologically active corresponding 3,4-dihydropyrimidin-2-(1H)-one/thione derivatives under solvent-free conditions. This eco-friendly protocol provi...

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...

By the immobilization of bipyridinium chloride onto mesoporous MCM-41encapsulated Fe3O4 nanoparticles via a simple post-synthesis method, a totally new organic-inorganic hybrid nanocomposite was formulated. The heterogeneous hybrid nanomagnetic composite was characterized by <spa...

&lt;p&gt;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&lt;sub&gt;2 &lt;/sub&gt;has more surface area easily binds with active site reactive molecule ini...

A new magnetically separable organic-inorganic nanohybrid catalyst denoted as CuFe2O4@SiO2@C3-Pyrazole-C4SO3-H2PW was successfully prepared by grafting of a functionalized ionic liquid containing a pyrazolium cation with a phosphotungstic count...

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 ...

A simple and highly efficient protocol for the synthesis of derivatives 7, 7-dimethyl-4-phenyl-2-thioxo-2, 3, 4, 6, 8-hexahydro-1H-quinazoline-5-one from 5, 5-dimethyl cyclohexane-1, 3-dione (4a–4h) (dimedone) has been described. The aryl aldehydes were substituted with thiourea in presence synthesized zinc ferrite nanocatalyst, which increased yield under reflux through condensation, followed ...
