The last two decades have seen the discovery and the subsequent enormous growth in the field of nano- materials. The impact of size upon the properties of materials is now a well-known and well-proven phenomenon. However, the approach for the preparation of desired nano-materials is of prime importance. The chemical (bottom-up) approach has many-fold advantages over the other conventional and non-conventional preparatory methods. This book, therefore, covers the bottom-up approach for preparation of nano-materials and the subsequent uses as reversible hydrogen storage materials. The...
