These novel materials catalyze the oxidation of benzyl alcohol to selectively benzaldehyde at moderate temperatures using peroxides and molecular oxygen as oxidant. Electron paramagnetic resonance and X-ray photoelectron spectroscopic studies revealed that the acidity of the support (MCM-41) influences the electronic structure of the immobilized CuPc. On acidic supports a part of copper in CuPc got reduced from a ``formal'' +2 to +1 oxidation state. This reduction of copper in its oxidation state on different supports decreased in the order: Al-MCM-41 (Bronsted and strong Lewis acid sites) &gt; MCM-41 (silanol sites) &gt; Ti-MCM-41 (weak Lewis acid sites). A linear variation in catalytic activity with the concentration of Cu(1+) ions in different catalyst samples was observed. The study reveals that by suitably modifying the acidic properties of the support one can, in principle, fine-tune the electronic and catalytic properties of the active oxidation sites.</p>10aCopper phthalocyanine10aEPR10aMCM-4110aSelective oxidation of benzyl alcohol10aUV-visible spectroscopy1 aHamza, A.1 aSrinivas, D.  uhttps://library.ncl.res.in/content/selective-oxidation-benzyl-alcohol-over-copper-phthalocyanine-immobilized-mcm-41-002128nas a2200277   4500008004100000022001400041245007700055210006900132260008800201300001200289490000700301520119600308653001701504653001401521653002301535653002501558653002801583100001701611700002001628700002401648700001801672700001701690700001601707700001901723856010801742       2015                        eng d  a0217-984900aBiosynthesis of silver nanoparticles by using ganoderma-mushroom extract0 aBiosynthesis of silver nanoparticles by using ganodermamushroom   a5 TOH TUCK LINK, SINGAPORE 596224, SINGAPOREbWORLD SCIENTIFIC PUBL CO PTE LTDcMAR  a15400470 v293 a<p>Present study reports the biochemical synthesis of silver nanoparticles (Ag-NPs) from aqueous medium by using the extract of medicinal mushroom Ganoderma, as a reducing and stabilizing agents. The Ag-NPs are prepared at room temperature by the reduction of Ag+ to Ag in aqueous solution of AgNO3. The resultant particles are characterized by using UV-visible spectroscopy, Fourier transform infrared (FTIR) spectroscopy and transmission electron microscopy (TEM) measurement techniques. The formation of Ag-NPs is confirmed by recording the UV-visible absorption spectra for surface plasmon resonance (SPR) where peak around 427 nm. The prominent changes observed in FTIR spectra supported the reduction of Ag+ to Ag. The morphological features of Ag-NPs are evaluated from HRTEM. The spherical Ag-NPs are observed in transmission electron microscopy (TEM) studies. The particle size distribution is found to be nearly uniform with average particle size of 2 nm. The Ag-NPs aged for 15, 30, 60 and 120 days showed no profound effect on the position of SPR peak in UV-visible studies, indicating the protecting/capping ability of medicinal mushroom Ganoderma in the synthesis of AgNPs.</p>10aBiosynthesis10aGanoderma10amedicinal mushroom10asilver nanoparticles10aUV-visible spectroscopy1 aEkar, S., U.1 aKhollam, Y., B.1 aKoinkar, Pankaj, M.1 aMirji, S., A.1 aMane, R., S.1 aNaushad, M.1 aJadhav, S., S.  uhttps://library.ncl.res.in/content/biosynthesis-silver-nanoparticles-using-ganoderma-mushroom-extract-1
