Photocatalytic Reduction of Carbon Dioxide: Issues and Prospects
Authors: Hariprasad Narayanan, Balasubramanian Viswanathan and Suguna YesodharanBackground: The conversion of carbon dioxide into worthwhile chemicals through photo-catalysis has been a matter of attraction for the last four decades among the scientific community. However, the conversion rate has not yet been achieved to the desired efficiency due to the inevitable barriers associated with the process making it as a Holy Grail. This presentation deals with the identification and critical evaluation of the Read More

Coke Alternate Movement in Faujasite Based Catalysts Deactivated from Butene Alkylation
Background: Examples of alternate dynamics phenomenon observed in zeolites were listed. A special attention was paid to coke alternate dynamics phenomena in deactivated HZSM5 zeolite catalysts and shortcomings of its interpretation. Present investigation deals with a coke movement of different vectors observed in deactivated catalysts based on X faujasite. Methods: Two catalysts on the base of X zeolite by means of iso Read More

Keplerate Polyoxotungstate Nanowheel Functionalized Magnetic Nanoparticles for Sustainable Biodiesel Production by Esterification of Free Fatty Acids with Ethanol in an Ultrasound-Assisted
By Reza HaddadBackground: Biodiesel is briefly defined as the monoalkyl esters of vegetable oils or animal fats. Biodiesel is the best candidate for diesel fuels in diesel engines as a "green chemistry" that has several advantages over conventional diesel. Giant polyoxometalates are nanoscale architectures with highest Euclidean symmetry, which gained signi#129;cant interest as cation carriers or nanosponges and for various other material Read More

Transfer Hydrogenation Studies of Aromatic Nitro Groups Over Nickel-Boron Amorphous Alloy Catalysts
Authors: Anant A. Chavan, Anand S. Burange and Radha V. JayaramBackground: Nickel-Boron amorphous alloys (catalysts) of various Ni:B ratio were synthesized and well characterized using XRD, ICP-AES, EDAX and IR spectroscopic technique. Among all the catalysts, Ni:B alloy catalyst with ratio 1:1 was found to effective for catalytic transfer hydrogenation reaction using hydrazine hydrate as a proton donor. The present work shows the effect of metalloid content and the presence of aniline Read More

One Pot Synthesis of Carbon/Ni Nanoparticle Monolithic Composites by Nanocasting and Their Catalytic Activity for 4-Nitrophenol Reduction
Authors: Charitha J. Thambiliyagodage, Yasemin Hakat and Martin G. BakkerBackground: There is considerable interest in using transition metal catalysts in place of rare and expensive precious metal catalysts in fixed bed catalysis. The use of hierarchically porous materials potentially provides a method of improving mass transport and decreasing sintering and metal particle growth that leads to decreased catalytic activity. Methods: Composites consisting of nickel nanoparticles incorporated in a hierar Read More
