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...
