“…Recent studies have reported the use of porous BN for gas phase and liquid phase adsorption. The focus has mostly been on CO 2 capture [4][5][6], H 2 storage [7][8][9][10], pollutants removal from air [11,12], water pollutants removal [7,[12][13][14][15][16][17][18][19][20][21][22] and oil adsorption [15,21,22]. For instance, recent work by Nag et al [5] reported the synthesis of boron nitride with a CO 2 adsorption capacity of up to 32 wt.…”

“…Indeed, the latter (and few) studies either used different testing conditions that are not relevant to CO 2 capture (e.g. lower temperatures) [4,5], or reported a lower capacity when tested under the same conditions [6]. Since N 2 is another major component of the flue gas, the material was tested for N 2 adsorption under the same conditions (1 bar, 25 °C) using a gravimetric technique and no uptake was measured indicating promising selectivity.…”

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.

“…Porous materials are extensively used as catalyst supports, gas adsorbents, sensors, for chemical purification and separation due to their high surface area and high porosity [1][2][3][4][5][6][7][8][9]. Traditional porous oxide supports such as Al 2 O 3 , SiO 2 , and zeolite have been widely utilized, whereas the low thermal conductivity and high sensibility to moisture may sometimes result in some disadvantages, such as causing severe metal sintering on the hot spots, and making the catalyst be covered with water at low temperature [10][11][12][13].…”

The physisorption of methane in homogeneous armchair open-ended SWBNNT triangular arrays was evaluated using grand canonical ensemble Monte Carlo simulation for tubes 11.08, 13.85, 16.62, and 19.41 Å [(8,8), (10,10), (12,12), and (14,14), respectively] in diameter, at temperatures of 273, 298, 323, and 373 K, and at fugacities of 0.5-9.0 Mpa. The intermolecular forces were modeled using the Lennard-Jones potential model. The absolute, excess, and delivery adsorption isotherms of methane were calculated for the various boron nitride nanotube arrays. The specific surface areas and the isosteric heats of adsorption, Q(st), were also studied, different isotherm models were fitted to the simulated adsorption data, and the model parameters were correlated. According to the results, it is possible to reach 108% and 140% of the US Department of Energy's target for CH(4) storage (180 v/v at 298 K and 35 bar) using the SWBNNT array with nanotubes 16.62 and 19.41 Å in diameter, respectively, as adsorbent. The results show that for a van der Waals gap of 3.4 Å, there is no interstitial adsorption except for arrays containing nanotubes with diameters of >15.8 Å. Multilayer adsorption starts to occur in arrays containing nanotubes with diameters of >16.62 Å, and the minimum pressure required for multilayer adsorption is 1.0 MPa. A brief comparison of the methane adsorption capacities of single-walled carbon and boron nitride nanotube arrays was also performed.
