“…The second class of synthesis method -templating method -uses a sacrificial material to control the porosity of the resulting BN. Some examples of templates employed include mesoporous silica, carbonaceous materials and zeolites [25][26][27]. Various organic compounds have also been mixed with boron and nitrogen precursors and used as structure-directing agents to produce porous BN, such as for instance cetyl-trimethylammonium bromide [28], or the triblock copolymer (P123) [12].…”

Boron nitride (BN) has applications in a number of areas: it can be used as lubricant, as insulating thermoconductive filler or UV-light emitter. BN can also capture large amounts of hydrocarbons and gaseous molecules, provided that it exhibits a porous structure. This porous structure also enables its application as a drug-delivery nanocarrier. Little if anything is known on controlling the porosity of BN, even though it has tremendous implications in terms of adsorption performance and drug delivery properties. To address * Corresponding Author: Camille Petit, camille.petit@imperial.ac.uk M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT 2 this aspect, we provide for the first time an in-depth investigation of the effects of the synthesis conditions on the formation of porous BN. The material was also tested for CO 2 capture. We found that the intermediate preparation is of paramount importance and can in fact be used to tune the porosity of BN. Owing to a combination of spectroscopic and thermal analyses, we attributed this phenomenon to the variation of the thermal decomposition pattern of the intermediates. The most microporous BN produced was able to capture CO 2 while not retaining N 2 . Overall, this study opens the route for the design of well-controlled porous BN structures to be applied as adsorbents and drug-delivery carriers.

“…It has been widely studied in the nineties by Economy et al to prepare BN in forms of carbon fiber-reinforced matrix composite [41][42][43], whereas its chemistry has mainly been studied by Sneddon et al [44,45]. More recently, our group demonstrated the interest to use PBZ to prepare various shapes of BN [46][47][48][49][50]. PBZ is synthesized with controlled cross-linking degrees by selfcondensation of BZ at a low temperature inside an autoclave.…”

“…The chemistry (elemental composition, compositional homogeneity and atomic structure), the processing properties and the reactivity (thermal and chemical) of related polymers can efficiently be controlled and tailored to supply, after shaping and pyrolysis processes, non-oxide ceramics with the desired compositional phase distribution and homogeneity as well as shape. This concept is particularly adapted to the preparation of porous non-oxide ceramics [48,50,95,96]. The so-called nanocasting provides access to tunable pore morphologies and allows elaborating architectured PDCs by (i) replicating the nanostructure/architecture of a template material into a locally ordered pore system through the impregnation of the template with a preceramic polymer solution or melt, (ii) performing the subsequent pyrolysis then (iii) removing the mold.…”

The controlled synthesis of boron nitride at the nanoscale with predefined and uniform nanostructures and architectures is in general a big challenge, and making full use of these materials in applications still requires great effort. In this article, recent progress on the synthesis of nanostructured and architectured boron nitride involving molecular and polymeric precursors which contain only boron, nitrogen and hydrogen are reviewed. The potential applications of these materials with controlled porosity and/or dimensions controlled at the nanoscale as zero, one, two and three dimensional materials are discussed. Finally, future prospects for boron nitride in terms of synthesis and applications are considered.

3D white graphene foam scavengers: vesicant-assisted foaming boosts the gram-level yield and forms hierarchical pores for superstrong pollutant removal applications

Three-dimensional (3D) nanostructures assembled with one-or few-layered ultrathin two-dimensional (2D) crystals have triggered great interest in energy and environmental applications. Here, we introduce a gas-foaming process in an hexagonal boron nitride (h-BN) ceramic material to fabricate 3D white graphene (WG) foams without using any catalysts or templates for superstrong pollutant removal applications. Importantly, the introduction of vesicants guaranteed the reproducibility and yield (4500 cm 3 ). Interestingly, these 3D WG foams possessed a vesicular structure with hierarchical pores ranging from nm to μm scales and with ultrathin walls consisting of mono-or few-layered BN membranes with planar sizes as large as 100 μm. Consequently, such microstructure merits of hierarchical pores and ultrathin walls endowed them not only very low density (2.1 mg cm − 3 ) but also superstrong adsorption ability, illustrated by capacitances up to 190 times its own weight toward a wide range of environment contaminations, including various oils and dyes. Thus, the 3D h-BN WG foams prepared by vesicant-assisted foaming should have great potential as outstanding environmental scavengers. NPG Asia Materials (2015) 7, e168; doi:10.1038/am.2015.8; published online 27 March 2015 INTRODUCTION Two-dimensional (2D) crystals, such as graphene 1 and white graphene (WG, mono-or few-layered hexagonal boron nitride (h-BN)), 2,3 have triggered great interest because of their extraordinary intrinsic properties and wide range of applications in electronics, optoelectronics, energy storage and the environment. 4 However, for some specific applications, such as the adsorption of various contaminants and as electrodes in electrochemical cells, their pristine flat 2D structures have been recognized to not fully match the practical requirements. [5][6][7][8] In contrast, three-dimensional (3D) architectures using 2D crystals as building blocks can simultaneously provide the virtues of 2D and 3D structures, such as ultrathin sheets and large specific surface areas from 2D sheets 6 and hierarchical pores and ultralight densities from 3D configurations. 7 Recently, such novel 2D-3D structure features have been proven to exhibit new and outstanding performances. For instance, graphenecarbon nanotube 3D structures had densities as low as 0.16 mg cm − 3 , even lighter than air (1.29 mg cm − 3 ); 9 3D graphene and BN networks exhibited excellent mechanical properties; 10,11 3D BNC hybrid networks showed tunable electronic and thermal properties. 12 However, the high-yield fabrication of such 3D architectures of 2D crystals, especially without using any templates or catalysts, remains a great challenge. Currently, there are two methods for fabricating 3D
