Nanocatalysis has emerged as a field at the interface between homogeneous and heterogeneous catalysis and offers unique solutions to the demanding requirements for catalyst improvement. Heterogeneous catalysis represents one of the oldest commercial applications of nanoscience and nanoparticles of metals, semiconductors, oxides, and other compounds have been widely used for important chemical reactions. The main focus of this fi eld is the development of well-defined catalysts, which may include both metal nanoparticles and a nanomaterial as the support. These nanocatalysts should display the benefits of both homogenous and heterogeneous catalysts, such as high efficiency and selectivity, stability and easy recovery/recycling. The concept of nanocatalysis is outlined in this book and, in particular, it provides a comprehensive overview of the science of colloidal nanoparticles. A broad range of topics, from the fundamentals to applications in catalysis, are covered, without excluding micelles, nanoparticles in ionic liquids, dendrimers, nanotubes, and nanooxides, as well as modeling, and the characterization of nanocatalysts, making it an indispensable reference for both researchers at universities and professionals in industry.

Fine Rh nanoparticles can be deposited uniformly on surfaces of carboxylate functionalized MWNTs using the one-pot sonochemical method. The CNT-supported Rh nanoparticles show remarkably high catalytic active and are reusable for hydrogenation of arenes at room temperature. Complete ring saturation of polycyclic aromatic hydrocarbons (PAHs) can be achieved under mild hydrogenation conditions using the MWNTs catalyst that can not be done by commercially available Rh nanocatalysts (Rh- Escat 3401 ). This technique also provides a simple and rapid way of making Rh nanoparticles of different size, which allows us to study particle size effects on catalysis. Furthermore, we extended the sonochemical method to synthesize well-dispersed Pt-Rh alloy bimetallic nanoparticles on sidewalls of CNTs and studied the potentially improved activity (synergistic effect) for room temperature catalytic hydrogenation of neat benzene, neat alkylbenzenes, and PAHs.

The main objective of the present thesis is to deepen the understanding of the mechanisms involved in catalytic growth of carbon nanotubes (CNT) and related processes, such as the catalytic hydrogenation, and to use this knowledge to optimize the experimental approaches in order to gain better control in the synthesis and modification of carbon nanomaterials. Controlled growth of the CNT is achieved using gas-phase prepared catalyst particles (Fe, Co) which serve as individual catalytic nucleation sites in a chemical vapor deposition (CVD) process. These studies highlight that the controlled preparation of catalyst particles is a crucial step in order to control the CNT morphology. The resultant CNT diameter and the CNT density are found to increase with increasing nanoparticle diameter and density, respectively. The number of walls of the CNT also increases with increasing primary catalyst size. The experimentally derived correlations between the particle diameter on one hand and the CNT diameter and the CNT number of walls on the other hand are attributed to an increase of the catalyst's volume-to-surface area ratio with increasing particle size. While the availability of carbon dissolved within the catalyst at the point of nucleation is determined by the catalyst volume, the amount of carbon required to form a cap depends on the surface area of the catalyst particle. Electron microscopy studies of the catalyst/substrate/carbon interfaces of CNT grown from Fe nanoparticles reveal that the CNT walls are anchored to the oxide substrate which contests the general argument that the CNT walls stem from atomic steps at the catalyst. It is argued that after nucleation, the substrate itself provides a catalytic functionality towards the stimulation of ongoing CNT growth, whereas the catalytic activity of the metal particle is more restricted to the nucleation process. Selective hard-magnetic functionalization of CNT tips has been achieved in a plasma-enhanced CVD process.

Hydrogenation is a key reaction in both the food and petrochemical industries, where it is used to reduce carbon–carbon double bonds. Without a catalyst, hydrogenation reactions require extreme temperatures to occur, meaning catalysts are essential for the reaction to be industrially useful. During the past decade, the properties of many carbon nanomaterials that are relevant to hydrogenation catalysis have been described, including carbon nanotubes (CNTs), carbon nanofibers (CNFs), carbon nanohorns (CNHs), graphene oxide (GO), reduced graphene oxides (rGO) and fullerenes, that are relevant to hydrogenation catalysis, have been described. For many of these the production methods have advanced to the commercial stage. Numerous studies on the development of catalysts on carbon nano-supports have appeared in the scientific literature and these catalysts have shown remarkable activity and specificity. Carbon Nanomaterials in Hydrogenation Catalysis is a valuable reference for researchers and chemical engineers working on improving hydrogenation processes and those interested in applications for carbon nanomaterials. Covering their production, modification and applications as a catalyst support this book provides an in-depth review of the current state-of-the art in using carbon nanomaterials for hydrogenation reactions.

This book systematically summarizes the advanced development of carbon-based nanomaterials for electrochemical catalysis, and it is comprised of four sections. The first section discusses about the fundamental synthesis, characterization techniques, and catalytic effects on the energy conversion and storage mechanism. The second section elaborately reviews various types of electrocatalytic reactions on carbon-based materials and their performance. The third section focuses on batteries about carbon-based materials with different storage mechanism. And the last one, the following enlightenment in terms of theoretical development and experimental research is provided to the general readers: 1) Precise design and construction of local atomic and electronic structures at the interface of catalysts; 2) Selective activation and directed conversion of carbon-based energy-carrying molecules at the interface; 3) Interaction mechanism and regulation of catalyst solid surface interface properties under environment and external field. This book will be useful for researchers and students who are interested in carbon-based nanomaterials, electrochemical catalysts and energy storage.
