This book is an edited collection of authors papers regarding research on sulfo-functionalized nanoporous silica, published with various renowned journals. It provides in-depth scientific research findings on synthesis and characterization of sulfo-functionalized nanoporous silica typically with pore sizes in mesopores and micropores range. Detailed synthesis and characterization techniques are recorded with insightful discussion and findings. The use of ammonia adsorption microcalometry for characterization and application of such materials could also be found in the book. Besides synthesis with conventional route, the author also found a novel route to produce this material, which is noted in this book as Facile Synthesis of Sulfo functionalized mesoporous silica. This book would be helpful in giving a comprehensive understanding to undergraduate and postgraduate students, as well as academics and researchers who are involved in materials sciences and chemical engineering research.
