Abstract
The direct conversion of CO2 into important solid materials is one of the most attractive research topics. In this communication, we report an invention, namely, the reaction of CO2 and Na to form three dimensional crape myrtle flower-like graphene with superior properties of a large surface area and high conductivity. Furthermore, the dye-sensitized solar cell (DSSC) with the 3D graphene as a counter electrode exhibited a high energy conversion efficiency of 10.1%, which is much higher than that (7.7%) of the DSSC with an expensive Pt counter electrode. This provides a promising method to synthesize electrode materials and a novel approach to utilize a greenhouse gas.
