(196af) Transition Metal-Based Nanocrystals Confined-Growth on Heteroatom-Doped Graphene Toward Hydrogen Catalysis

With the combination of excellent electrical conductivity, high mechanical strength and surface area, graphene has been utilized as unique template for growth of nanomaterials, and further broadly applied in various research areas, such as environmental treatment and energy storage. Here, we will discuss and develop a new method of surface functionalization on graphene by UV-assisted in situ polymerization. In order to fully utilize the specific properties of both graphene and functional polymers, we will further explore the potential application by introducing graphene oxide and pristine graphene foam as templates, polyacrylamide (PAM) and gelatin with acryl groups (GelMA) as polymer scaffolds, to fabricate novel micro/nanostructure graphene-based composites, in which, not only the graphene can guide the polymerization as a template, but also the surface grafted polymer chains will turn the hydrophobic graphene surface to be highly hydrophilic, and simultaneously increase the integral mechanical strength and surface area with more active sites for storage of functional grains (like Transition Metal Phosphides and Chalcogenides).
