B-Doped Graphene Aerogels
Heteroatom doping has been an effective strategy to enhance the electrochemical performance of graphene materials. Among various heteroatoms, boron (B) atoms may be easily doped into graphene aerogels since they possess similar size and valence electron numbers in comparison with carbon (C) atoms. At present, B-doped graphene aerogels have been extensively studied and fabricated, and their application in energy storage materials and environmental protection has received special attention.

Features
Applications
B-doped graphene aerogels can be used as electrode materials. Li and co-workers[1] fabricated B-doped graphene aerogels through a simple hydrothermal method, and applied them to electrode materials for supercapacitors. The supercapacitors exhibit a high specific capacitance, outstanding cycling stability, as well as high energy and power densities, which rely on the combination of mesoporous structure, high specific surface area and abundant defects of B-doped graphene aerogels. Similarly, the study by Xie et al[2]. suggested that B-doped graphene aerogels were ideal cathode materials for lithium-sulfur batteries.
In addition to being electrode materials, studies have shown that graphene aerogels doped with a specific concentration of B can effectively degrade mutagenic and refractory organic pollutants under visible light irradiation[3]. Therefore, B-doped graphene aerogels can be used in modern wastewater treatment technology.
In general, the two most important steps in aerogel synthesis are network formation and drying. Sometimes, in order to obtain some special properties, aerogels are modified by some specific methods after drying.
