“…For thermal storage applications, the thermal stability of the B‐C‐N foams is an important practical attribute. Results of thermogravimetric analysis (TGA) for B‐C‐N foam (Figure 7c) treated 30 min in microwave and annealed at 1100 °C reveals no measurable weight loss of the sample in heating up to 1000 °C, thus confirming prior results on powder samples 43. The intact foam ligaments even after chemical treatment (inset of Figure 7c) with modified surface activation by B and N doping have been achieved.…”

The modifi cation of microporous carbon foam with boron and nitrogen through a facile microwave chemical treatment are reported. The resulting surfaces of the foam exhibit distinct B-N and carbon domains based on chemical and microscopic analysis, in keeping 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 consequently are suggested as candidate materials for sorption cooling and thermal storage applications using methanol as the adsorbate.

In the last four to five years, there has been a great resurgence of research on two-dimensional inorganic materials, partly because of the impetus received from graphene research. Unlike graphene, which is a gap-less material, most inorganic layered materials are semiconductors or insulators. Some of them, as exemplified by MoS 2 , exhibit unexpected properties, not unlike graphene, with possible applications. Thus, layered metal chalcogenides are being explored intensely, and MoS 2 is emerging as a wonder material. In this article, we present the synthesis and properties of nanosheets composing single or few layers of these fascinating materials. Besides metal chalcogenides, boron nitride, borocarbonitrides (B x C y N z ), metal oxides, and metal-organic frameworks are also discussed.

The discovery of graphene has aroused great interest in the properties and phenomena exhibited by two‐dimensional inorganic materials, especially when they comprise only a single, two or a few layers. Graphene‐like MoS2 and WS2 have been prepared by chemical methods, and the materials have been characterized by electron microscopy, atomic force microscopy (AFM) and other methods. Boron nitride analogues of graphene have been obtained by a simple chemical procedure starting with boric acid and urea and have been characterized by various techniques that include surface area measurements. A new layered material with the composition BCN possessing a few layers and a large surface area discovered recently exhibits a large uptake of CO2.
