▎ 摘　　要

NOVELTY - Production of porous macrostructure of graphene and silver particles involves synthesizing sponges, foams, hydrogel, aerogel and three-dimensional graphene decorated with silver nanoparticles and/or microparticles, and forming a nanocomposite comprising a macroporous structure based on three-dimensional graphene and decorated with silver nanoparticles and/or microparticles. In the composite, the carbon atoms are arranged in a sheet-like nanostructure, the carbon-based hydrogel is a hydrogel of graphene, the carbon-based aerogel is an aerogel of graphene, and the silver nanoparticles and/or microparticles are distributed over the sheets of the graphene. USE - Production of porous macrostructure of graphene and silver particles. Uses include but are not limited to water treatment, biomedicine, energy generation device, energy conversion device, energy accumulation devices, sensors, electromagnetic shielding, wave absorption and catalysis. ADVANTAGE - The method is simple, economical, environmentally-friendly, rapid, quickly provides porous macrostructures in large quantities without using toxic reagents under conditions of low temperature and low pressure, ensures low energy consumption, and allows to shape the morphology, properties and applicability of the macrostructures according to the quantity and order of addition of the reagents used. The macrostructure has low density, high thermal stability, static resistance, thermal management, and heat conduction and dissipation property.
