It's well known that material science is a stereoscopic world. 3D architectures provide versatile approaches to enhance the performance of products. On the other hand, graphene has been widely explored for applications in electronics, actuators, catalysis and bio- or energy related systems. Thus, graphene materials are significant to be fabricated or assembled into desired nano-architectures for tuning their electrical, mechanical, chemical or electrochemical properties. Here, a green and novel method has been developed to prepare 3D graphene architectures wrapping nanoparticles inside the network. The obtained graphene/Ag aerogels are electrically conductive, porous, and lightweight, accessible to different graphene-based multifunctional nanocomposites in the form of macroscopic hydrogels or aerogels. The potentialities of them for various applications (antibacterial, catalyst system, and supercapacitor) have been being investigated.
