P-Doped Graphene Aerogels
The quality of electrode materials is one of the most important factors in determining the overall performance of capacitors. Carbon nanomaterials have been widely used in studying electric double layer capacitor (EDLC) electrodes due to their high conductivity and large specific surface area compared with commercially activated carbon electrodes. Among the existing carbon materials, graphene has received widespread attention, especially graphene aerogels. However, according to the second law of thermodynamics, graphene is not stable and reduces its own energy through spontaneous agglomeration. Therefore, the specific surface area and electrical conductivity of graphene are much smaller than theoretical values in practical applications.
To solve these problems, graphene can be doped with phosphorus (P). In the study of Nie and co-workers[1], a simple solvothermal method was used to prepare highly porous P-doped graphene aerogels, using graphene oxide as a precursor and phytic acid as a dopant. The P-doped graphene aerogels in this study have the advantages of low cost, safety, reliability, and excellent electrochemical performance, and thus have superior application potential. In addition, Yang et al[2]. first reported P-doped graphene aerogels as self-supporting catalysts to facilitate C-C coupling for CO2 reduction to EtOH. One reason is that the hierarchical pore structure of P-doped graphene aerogels exposes abundant active sites, which are conducive to mass/charge transfer. This study provides novel insight into designing metal-free catalysts for liquid products from CO2 electroreduction.
