This much-needed book highlights recent advances and current trends in nanoparticle catalysis. It gives a comprehensive overview of modern and efficient tools for the synthesis of nanoparticles in solution or onto supports. Further emphasis is on the application of metal nanoparticles in important catalytic reactions, e.g. the production of hydrogen by dehydrogenation of amine-boranes or water-splitting, coupling reactions, as well as the transformation of biomass and carbon dioxide into fuels or added-value chemicals. Chapters on activation methodology and theoretical modeling of nanoparticles for catalysis and supported nanoclusters are also included. Written by an international team of leaders and young experts in the field, the book is an indispensable source of information for researchers and professionals, both in academia and industry, working in homogeneous and heterogeneous catalysis as well as nanotechnology.
