Graphite chemists and electrochemists have joined forces to describe a novel hybrid system where lithium is most likely stored as a metal in the pores of mesoporous silica.
Xinliang Feng, Klaus Müllen, and co-workers have prepared various 2D nanosheets with a high aspect ratio, surface area, and monodispersibility by using graphene as a template. With a bottom-up strategy, they produced porous SiO2-graphene-porous SiO2 and porous cobalt oxide-graphene-cobalt oxide sandwichlike sheets. These sheets have morphology similar to that of graphene ranging from 200 nm to several micrometers in size with mesopores of about 2 nm.
To quote the authors of this exciting research: “We expect that our strategy will be applied to a variety of 2D nanosheet materials to promote their broad applications across the ranges of catalysis, sensors, supercapacitors, and batteries”.
