• Young Scientist Conclave Presentation at IISF-2016, National Physical Laboratory (NPL), Delhi, India.
• Work package 1 (WP1): Legendary bottom-up approach is very simple way to synthesize nanoparticles. Classical heating method like Microwave Assisted Solvothermal Technique (MWI) shows very good results, as MWI mainly enables the silent features i.e. 3R means reduce, recycle and reuse. MWI mainly obeys green route of synthesis such as less time consuming, uniform heating.
• Metal nanoparticles have drawn lots of attention in the recent decades due to their size and shape-dependent physical and chemical properties. Nanoscale metal clusters and colloids have unique physical and chemical properties.
• Amongst all of many metals, synthesis of ruthenium, palladium, rhodium, and nickel have been studied with a wide variety of experimental techniques such as solvothermal, microemulsion and microwave assisted solvothermal technique.
• Work package 2 (WP2): The materials with hierarchically macro-mesoporous structures are of great interest as potential catalyst supports, catalysts and adsorbents, which is due to their large specific surface area and, more important, their texture mesopores and intrinsic interconnected macropore network being able to efficiently transport guest species to framework catalytic sites.
• Herein the speaker will try to optimize the study of both WP1 & WP2 and will discuss
Microwave Irradiation Solvothermal Technique used for preparation of various noble metal nanoparticles supported on γ-Al2O3 (0.2-1 wt% metal loading) as well as for synthesis of mesoporous alumina.
• To study the synthesis route, effect of temperature and time by MWI technique for the preparation of metal nanocatalysts.
• Ethylene glycol used in the synthesis process plays a dual role (solvent and reducer).
• To study the synthesis of hierarchically mesoporous structured alumina by MWI Technique.
• Synthesized Ru nanoparticles and mesoporous alumina and their characterisation by UV-Vis, DLS, XRD, TEM, SEM, and Turbiscan.
• Ru/γ-Al2O3 (0.2-1wt%) synthesized by MWI screening for suitable nanocatalyst for range of hydrogenation reaction in current significant filed in competition with commercial catalyst.
• Work package 3 (WP3): Various applications have been studied for the synthesized nanocatalysts in the current significant field such as ; i) Hydrogenation of Aromatic analogue to synthesis industrially valuable fine chemicals and ii) Hydrogenation of biomass to biofuels (Levulinic acid (LA) to Gamma Valerolactone (GVL) to 2-methyl tetrahydrofuran (2-MTHF).
• Levulinic acid and γ-valerolactone upon hydrogenation in presence of transition metal catalyst gives platform chemicals and also provide intermediates used for the formation of various fine chemicals like 1,4 propanediol (1,4 PDO), 2-Methyltetrahydrofuran (MTHF).
• Specially, upon hydrogenation of levulinic acid to MTHF is rarely focused area which is having high interest as MTHF is “P-Series” fuel and blender for fuel.
• Herein speaker will try to address on WP3 hydrogenation of LA to GVL to 2-MTHF in one route reaction cycle. Levulinic acid to gamma valerolactone and 2-MTHF, 16 bar, 220oC, 6h. Results: 100% conversion, 80% selectivity GVL, 20% selectivity 2-MTHF.
