Nanonickel catalyst reinforced with silicate for methane decomposition to produce hydrogen and nanocarbon: Synthesis by co-precipitation cum modified Stober method

Co-precipitation cum modified Stober method is a continuous process avoiding application of higher temperature treatment before supporting nanometal with SiO2, irrespective of pre-preparation methods. We have conducted the co-precipitation process without undertaking calcination under air in order t...
