Carbon-based photocatalysis has been considered as an economic, safe, renewable, and clean technology, for various applications. However, the pristine carbon material is usually restricted by unsatisfactory photocatalytic efficiency and practical applications due to the insufficient solar light absorption, the low-surface area, and the fast recombination of photogenerated electron-hole pairs. Various modification strategies, such as elemental and molecular doping, preparation of mesoporous carbon materials, and combination of conductive materials, are adopted to enhance the photocatalytic activity of carbon materials. In this book, we intend to describe the great potential of efficient and low-cost carbon-based materials in various realms, such as photodegradation of organic compounds, water splitting, and selective organic transformations.

Graphene oxide is a carbon-based material what produces a monolayer or a few layers of oxygen-functionalized graphene. The number of layers usually differentiate between graphene oxide and graphite oxide. Though a multilayer system, graphite oxide monolayer flakes and few-layer flakes can be found in a graphene oxide dispersion. Due to the presence of oxygen functionalities, graphene oxide can easily disperse in various organic solvents including water and is compatible with a different matrix that dramatically enhances electrical and mechanical properties when mixed with polymer and ceramic materials. Graphene oxide possesses a sp2 bonding network. Graphene oxide can be used as an intermediary in the production of single layer or few-layer graphene sheets. Graphene oxide can be reduced in solution and as a thin film using a variety of reducing conditions, and reduction converts the graphene oxide into a material that has a large enhancement in electrical conductivity. Graphene oxide has been used in a variety of applications not limited to materials science engineering and biotechnology. The present book describes the advances in research and applications of graphene oxide; in Chapter One, the general introduction on graphene oxide is introduced whereas in Chapter Two a broader summary of laser processing for graphene oxide/transition metal oxide nanocomposite coatings are described.
