This book consist a comprehensive review of several important organic synthesis carried out with various activated nano particles of metal-nonmetal oxides and mixed Metals. Most of the reactions are very important organic name reactions. This book focuses on topics like catalysis, organic synthesis, nano particles, nano catalysis, reusable catalysts and study of several Benzimidazoles derivatives synthesized by zirconia and sulfated zirconia with analysis like Mass, IR, powder XRD, DLS, NMR, etc is provided. Hence, This book is useful for researchers and students in Chemistry who want to have a brief introduction and practical aspect on Nanocatalyst. Authors of this book are very grateful to Pratik Suthar, Bhavna Kharvad for the Enormous contribution on this venture, without their influence this could not be published.
