2D nanomaterials have emerged as promising candidates for energy devices owing to their superior electrochemical properties, surface area, nanodevice integration, multifunctionality, printability, and mechanical flexibility. Handbook of 2D Nanomaterials: Fundamentals and Energy Applications, Two-Volume Set summarizes research for different materials in the 2D category such as graphene and its derivatives, transition metal chalcogenides, transition metal oxides/hydroxides, transition metal carbides/nitrides/carbonitrides, and 2D polymers for energy applications such as in batteries, supercapacitors, solar cells, and fuel cells. The first volume covers basics concepts, chemistries, and properties along with theoretical consideration in designing new 2D nanomaterials The second volume covers a wide range of applications of 2D nanomaterials for energy as well as future applications and challenges in fabricating flexible energy generation and storage devices Presents synthesis, characterization, and applications of 2D materials for green energy production and storage Explores new aspects of synthesizing 2D nanomaterials beyond traditionally layered structures Provides detail of novel methods and advanced technologies These handbooks are aimed at materials scientists, chemists, electrochemists, and engineers working in energy disciplines.
