▎ 摘　　要

Nanotechnology has provided us with unimaginable possibilities in addressing worldly challenges. Since its discovery in 2004, Graphene has been considered a "Holy Grail" of nanomaterials for its unprecedented applicability in different fields, including biomedical, energy harvest and storage, sensing applications. Throughout the world, tremendous waves of research have been going on to exploit graphene's unique thermal, mechanical, electrical, catalytic, and biological properties. Besides, efficient and tunable techniques of graphene's bulk manufacturing have been under thorough investigation. This article reviews various recent studies on large-scale graphene synthesis with tunable properties. Several different ways of graphene's use in various catalytic platforms are also reviewed. Furthermore, recent biomedical and energy (storage and harvest) applications of graphene, especially in microbial fuel cell technology, bio-sensing, antimicrobial applications, have been discussed in this article.
