Hydrogen and nanocarbon are the two most emerging research topics in the field of environmentally benign energy and material science, respectively. These two treasured products can be simultaneously produced by methane transformation in a single step chemical approach. Hydrogen, the simplest, the lightest and the most abundant element in the known universe appears to be one of the auspicious energy carriers. There has been an intense research effort on this topic in recent years. Hydrogen is ...

Abstract

Co-precipitation cum modified Stöber method is a continuous process avoiding application of higher temperature treatment before supporting nano-metal with SiO2, irrespective of pre-experimented methods. We have resumed co-precipitation process without undertaking calcination under air in order to avoid even a partial particle agglomeration and hence maintained average particle size ~30nm after enforcing with SiO2. It is a first report adopting such an unceasing preparation for prepar...

Abstract

n-Ni/SiO2, n-Fe/SiO2 and n-Co/SiO2 nano-catalysts were prepared by co-precipitation cum modified Stöber method and applied for thermocataltytic decomposition of methane in order to investigate their thermal stability and activity to produce greenhouse gas free hydrogen and nano-carbon. Mean particles sizes of produced nano-catalysts obtained from BET analysis are 32.19 nm, 30.26 nm and 49.92 nm, respectively. Temperature programmed methane decomposition were conducted as preliminary ...
