“…As shown in Table 2, systems Ta@V B and W@V B have ΔG max NRR larger than 0.55 eV and are not suitable for the NRR, while the others exhibit efficient catalytic activity. Re@V B shows the highest catalytic performance, with a low ΔG max NRR of 0.28 eV, which is comparable (or lower) to those of other recently reported efficient NRR catalysts, such as experimentally a certain percentage of B-doped graphene (0.50 eV), 51 V-doped g-C 4 N 3 (0.37 eV), 52 carbon-bound boron nitride nanoribbon edges (0.39 eV) 53 and Mo atom-bound defective boron nitride (0.35 eV). 30 However, it has been shown that the enzymatic mechanism might not be the best choice.…”

“…Considering the importance of these surface functional groups and doping level in energy applications, exfoliation or synthesis parameters should be carefully selected. So far, functionalization with the hydroxyl group [-OH] [44], amine group [-NH 2 ] [45], long change molecules [46,47], and doping with carbon [48], fluorine [49], and oxygen [50] have been largely used to modify 2D h-BN. Table 1 provides a summary of 2D h-BN synthesis for energy applications.…”

The prominence of two-dimensional hexagonal boron nitride (2D h-BN) nanomaterials in the energy industry has recently grown rapidly due to their broad applications in newly developed energy systems. This was necessitated as a response to the demand for mechanically and chemically stable platforms with superior thermal conductivity for incorporation in next-generation energy devices. Conventionally, the electrical insulation and surface inertness of 2D h-BN limited their large integration in the energy industry. However, progress on surface modification, doping, tailoring the edge chemistry, and hybridization with other nanomaterials paved the way to go beyond those conventional characteristics. The current application range, from various energy conversion methods (e.g., thermoelectrics) to energy storage (e.g., batteries), demonstrates the versatility of 2D h-BN nanomaterials for the future energy industry. In this review, the most recent research breakthroughs on 2D h-BN nanomaterials used in energy-based applications are discussed, and future opportunities and challenges are assessed.

“…The initial weight gain by h -BNNS-CTAB was attributed to the adsorption of N 2 molecules over the polar boron sites and edges . The density functional calculations further suggest that h -BN nanosheets exhibit excellent N 2 capture abilities even at room temperature, which are demonstrated to have originated from the edge lone pair electrons. − …”

Intrinsic low shear strength, excellent mechanical properties, and high thermal conductivity of two-dimensional h-BN nanomaterials make them promising alternatives to conventional metal-/phosphorus-/sulfur-based additives for the development of eco-friendly lubricant formulation. However, the poor dispersibility of h-BN nanomaterials in lubricating oils is a major challenge. Herein, a facile approach of strong alkali-assisted hydrothermal exfoliation and defect-sensitive etching of h-BN powder is demonstrated. The cetyltrimethylammonium bromide (CTAB) is grafted on the active and polar sites of h-BN nanosheets (h-BNNSs). DFT calculations, along with FTIR and XPS results, confirmed the synthesis of h-BNNS-CTAB, which showed good dispersibility in SN-150 mineral lube base oil. The uninterrupted supply of highly dispersible minute dose of h-BNNS-CTAB (0.003 wt %) to tribo interfaces of steel balls improved the lubrication properties of lube oil by decreasing friction (34%) and wear volume (75%). The enhanced tribo-performance is attributed to low shear strength arising from weakly stacked atomic lamellae in h-BNNS-CTAB and the tribo-induced deposition of h-BN lamellae on the contact interfaces of steel balls. The present work proposes a novel strategy for developing h-BNNS-based high-performance lubricant formulation, which can effectively minimize frictional energy and material losses.
