Summary: A facile microwave chemical treatment was performed for surfacial chemical modification of macroporous carbon foam with boron and nitrogen. The resulting surfaces of the foam exhibit distinct BN and carbon domains based on chemical and microscopic analysis, in agreement with theoretical predictions. The resultant materials are shown to exhibit exceptionally high methanol desorption enthalpy and thermal stability in comparison to untreated carbon foam, and subsequently are suggested as candidate materials for sorption cooling and thermal storage applications with methanol as the adsorbate. To increase the inferior surface area of carbon foam, petal-like structures made of few layer graphene were deposited over its entire surface by MPCVD technique. Further experiments with this material are on-going. In order to realize real hierarchical structure, we also synthesized a unique 3D material made of graphene-petals for tunable 3D nano-architecture for electronic cooling technology.
