This book provides a selected overview of some of the most interesting scientific results regarding the outstanding properties of carbon nanomaterials for gas adsorption and of interest both for basic research and technological applications. Topics receiving special attention in this book include storage of H, purification of H, storage of rare gases, adsorption of organic vapors, gas trapping and separation, and metrology of gas adsorption.

This book presents a summary of the current use of carbon nanomaterials for water treatment, drug delivery, systems and nanosensors. The first chapter elucidates the adsorption process phenomenon. Also, the properties of different carbon nanomaterials for adsorption applications are covered. The third chapter presents the kinetic and equilibrium models of adsorption, processing of experimental data and adsorption process peculiarities. Environmental and biological applications of carbon nanomaterials are listed in the last chapter. This book is written from an application-oriented perspective and is useful for all those interested in nanoadsorbents.

Rare gas adsorption was studied on suspended individual single walled carbon nanotubes and graphene. The devices were fabricated as field effect transistors. Adsorption of N2 and CO, which formed a Root 3 X Root 3 commensurate solid monolayer, produced a dramatic reduction of the two-terminal conductance of graphene by as much as a factor of three. This effect is possibly connected with the opening of a band gap expected to occur in such structures.

This book shows the promising future and essential issues on the storage of the supercritical gases, including hydrogen, methane and carbon dioxide, by adsorption with controlling the gas-solid interaction by use of designed nanoporous materials. It explains the reason why the storage of these gases with adsorption is difficult from the fundamentals in terms of gas-solid interaction. It consists of 14 chapters which describe fundamentals, application, key nanoporous materials (nanoporous carbon, metal organic frame works, zeolites) and their storage performance for hydrogen, methane, and carbon dioxide. Thus, this book appeals to a wide readership of the academic and industrial researchers and it can also be used in the classroom for graduate students focusing on clean energy technology, green chemistry, energy conversion and storage, chemical engineering, nanomaterials science and technology, surface and interface science, adsorption science and technology, carbon science and technology, metal organic framework science, zeolite science, nanoporous materials science, nanotechnology, environmental protection, and gas sensors.

The insulating medium used in gas-insulated switchgear is SF6 gas, which has been widely used in substations. Energy generated by discharge will cause the composition of SF6 and generate characteristic component gases. Diagnosing the insulation defect through analyzing the decomposed gases of SF6 by chemical gas sensors is the optimal method due to its advantages. Carbon nanotubes, TiO2 nanotubes and graphene are chosen as the gas-sensing materials to build specific gas sensors for detecting each kind of SF6 decomposed gases and then enhance the gas sensitivity and selectivity by material modification. The properties and preparation methods are introduced in this book. The author studied the micro-adsorption mechanism and macro-gas sensing properties by theoretical calculation and sensing experiment.
