RISPreyssler-type heteropoly acid: A new, mild and efficient catalyst for protection of carbonyl compounds
liquid acid is expected. So Preyssler-type
heteropoly acid (H14NaP5W30O110) has been introduced as an efficient alternative. The advantages of
Preyssler acid as a solid acid catalyst may include large number of balanced protons, strong...
Endohedral functionalisation of multi-wall carbon nanotubes by acidic cesium salt of Preyssler in nanosize
Nanoparticles of acidic cesium salt of Preyssler by a one-step solid-state reaction at room temperature, were synthesised and characterised by Fourier transform infrared spectroscopy, titration, inductively coupled plasma and transmission electron...
Catalytic Performance of Preyssler Anion in Selective Oximation of Aromatic Aldehydes
Preyssler catalyst, H14[NaP5W30O110], catalyzes the aldoximation of aromatic aldehydes for the synthesis of Z-isomers in conventional manner and under microwave irradiation. both pure acid and silica supported catalysts were used...
A NOVEL CATALYST FOR PHOTOSYNTHESIS OF GOLD NANOPARTICLES
Preyssler acid, H14[NaP5W30O110], as a green reducing agent and stabilizer, was used for the synthesis of gold nanoparticles by photolysis of Au(III)/Preyssler acid/propan-2-ol solution. Preyssler acid plays both the role of transferring electrons...
PHOTOCATALYSIS SYNTHESIS OF SILVER NANOPARTICLES USING PREYSSLER ACID
Synthesis of nanosized silver particles by chemical reduction using preyssler acid as a green polyoxometalate under UV irradiation was performed. In this study, formaldehyde and PVP (polyvinyl-pyrrolidone) was used as a reductant agent...
