Abstract

Disclosed herein are graphene coatings characterized by a porous, three-dimensional, spherical structure having a hollow core, along with methods for forming such graphene coatings on glasses, glass-ceramics, ceramics, and crystalline materials. Such coatings can be further coated with organic or inorganic layers and are useful in chemical and electronic applications.
