The research team of the National Centre for Catalysis Research has been contemplating on a book on ‘Nanomaterials’. This exercise has become a necessity since this subject has taken various manifestations in recent years. The learning and teaching of this subject are expected to take the centre stage in our educational institutions. The team has conceived the contents of this book keeping all these points in view.

As stated, Nanomaterials today have pervaded every sphere of human activity and hence can be presented in various formats. However, sector-wise application of nanomaterials yields a synthesis kind of approach and probably easy to comprehend. Hence this approach is adopted in this presentation.

The team does not claim any originality in the contents of this ebook. The team has strived to present the available material in a cogent, logical and comprehendible form so that the text may be utilized as a source material for a course on ‘Nanomaterials’. It is our hope that this ebook will serve this purpose.

The team members place on record their grateful thanks to all those who have contributed or will be contributing to the evolution of this ebook. This is a first attempt and hence it requires a proper growth.
