1 451 Indian Journal of Chemistry Sect. A: Inorganic, Bio-inorganic, Physical, Theoretical & Analytical CODEN: ICACEC; ISSN: (Print), (Online) Special Issue on Catalysis for Efficient Production of Chemicals VOLUME 53A NUMBER 4-5 APRIL-MAY 2014 CONTENTS 459 Characterization and reactivity of Pd supported on ZnAl 2 O 4 catalysts for direct coupling of ethylbenzene dehydrogenation with nitrobenzene hydrogenation Direct coupling of dehydrogenation of ethylbenzene with hydrogenation of nitrobenzene over ZnAl 2 O 4 supported palladium catalysts is slightly exothermic and also surpasses thermodynamic constraints. The ZnAl 2 O 4 supported Pd catalyst with palladium loading of 0.5 wt% exhibits good coupling performance to give high ethylbenzene conversion (52.3%) and styrene selectivity (88.3%) at 823 K. Yengaldas Harikrishna, Vanama Pavan Kumar, Komandur V R Chary & Vattikonda Venkat Rao* 467 Partial oxidation of methane to synthesis gas over Ni-supported ceria catalyst Rajib Kumar Singha, Astha Shukla, Shubhadeep Adak, Chandrashekar Pendem, Sandeep Saran & Rajaram Bal*

3 Molybdenum oxide supported on COK-12: A novel catalyst for oxidative dehydrogenation of ethylbenzene using CO 2 Oxidative dehydrogenation of ethylbenzene to styrene using CO 2 as a soft oxidant has been studied over molybdenum oxide supported on COK-12. The reaction is highly selective for styrene as a product and shows maximum activity over 14wt% MoO 3 /COK-12. Ramudu Pochamoni, Anand Narani, Venkata Ramesh Babu Gurram, Murali Dhar Gudimella, P S Sai Prasad, David Raju Burri & Kamaraju Seetha Rama Rao* 499 Mineralization of aqueous organic pollutants using a catalytic plasma reactor Plasma reactor has been utilized for the degradation and mineralization of a model aqueous organic pollutant, viz., methyl orange. Both degradation efficiency and mineralization of the dye increase as a function of time. P Manoj Kumar Reddy, Sk Mahammadunnisa & Ch Subrahmanyam*
4 Effective oxidative decolourization of azo dyes over Indian Ocean manganese nodules Manganese nodules show promising results for dye decolourization (100%) within a short time period. The decolourization is enhanced in the presence of NO 3 and SO 4. A K Sahoo, K M Parida* & P K Satapathy 511 Selective CO oxidation over Fe 5 (PO 4 ) 3 (OH) 5 supported Pt catalyst: Kinetic and mechanistic studies Pt supported on Fe 5 (PO 4 ) 3 (OH) 5 sample is found active for water gas shift at low reaction temperatures and is suitable for reverse water gas shift at high reaction temperatures. A Hari Padmasri*, P Anil Kumar, S Naveen Kumar, A Venugopal & Sooboo Singh 516 Characterization and reactivity of TiO 2 supported nano ruthenium catalysts for vapour phase hydrogenolysis of glycerol Ruthenium on titania catalysts prepared by depositionprecipitation method shows better conversion/selectivities during vapour phase hydrogenolysis of glycerol at moderate temperature and atmospheric pressure. The higher activity of Ru/TiO 2 catalyst is attributed to the presence of well-dispersed nanosized Ru particles on anatase titania. Vanama Pavan Kumar, Yengaldas Harikrishna, Nekkala Nagaraju & Komandur V R Chary*
5 Selective etherification of glycerol with tert-butanol over 12-tungstophosphoric acid catalysts supported on Y-zeolite M Srinivas, Rekha Sree, G Raveendra, Ch Ramesh Kumar, P S Sai Prasad & N Lingaiah* 530 Catalytic tri-reforming of glycerol for hydrogen generation M Ashwani Kumar, Ch Venumadhav, T V Sagar, M Surendar, N Lingaiah, G Nageswara Rao & P S Sai Prasad* 535 Preparation and structural investigations of new hexadentate Schiff base ligands and their bivalent metal complexes, and, catalytic applications of the complexes in allylic and benzylic C H bond activation Co(II), Ni(II) and Cu(II) complexes of two new Schiff base ligands have been prepared and characterized. These complexes catalyze the allylic and benzylic group oxidation reactions with (C H) bond activation. S Jyothi, G Raghava Rao, K Shashank, K Sridhar, Anjali Reddy, P Someshwar & S Jagannatha Swamy*

M Sudhakar, M Lakshmi Kantam*, R Kishore, S Naveen Kumar & A Venugopal* 553 Gas phase dehydrogenation of n-butanol to butyraldehyde on magnesia supported copper catalysts Gas phase hydrogenation of n-butanol to butyraldehyde has been carried out at atmospheric pressure on magnesia supported copper catalysts. Amongst the Cu/MgO catalysts with varying Cu loadings, the 10%Cu/MgO catalyst exhibits superior activity with 89% conversion of n-butanol and 98% selectivity for butyraldehyde. Yadagiri Jyothi, Venkateswarlu Vakati, Tirumalasetty Satyanarayana & Puppala Veerasomaiah*
7 Vapor phase chemoselective conjugate hydrogenation of isophorone over Pd/SBA-15 catalysts Pd/SBA-15 catalysts with 1, 2, 3, 4 wt% Pd loading prepared by a conventional impregnation method exhibit 100% conversion and 100% selectivity in gas phase at atmospheric pressure for chemoselective hydrogenation of isophorone to dihydroisophorone. Venkateswarlu Vakati, Saidulu Ganji, Ravi Kumar Marella, Kamaraju Seetha Rama Rao & David Raju Burri* 561 Synthesis, characterization and studies on optical properties of indium doped ZnO nanoparticles Indium doped ZnO nanoparticles have been synthesized by a simple aqueous solution based method. Doping leads to change in morphology of ZnO and the band gap of doped zinc oxide nanoparticles depends on the concentration of indium. Manu Sharma & P Jeevanandam*
