A simple precursor pyrolysis route to BCN nanoflakes

Recent advances in ternary two-dimensional materials: synthesis, properties and applications

“…Moreover, BCN materials with a tunable structure, including microspheres and nanoflakes were obtained by controlling the heat treatment of BCN organic precursor pyrolysis. 97,98 Recently, the in-vacuum thermolysis of a single-source precursor, ethane 1,2-diamineborane (BH3NH2CH2CH2NH2BH3), was performed to form bulk ternary BCN. The authors aimed to reduce the presence of oxides at the BCN surface, an essential issue linked to many potential applications of BCN materials.…”

“…Owing to the adjustable C content of the BCN, a tuned band gap was achieved. 82,98 Many attempts were made to explore other methods of obtaining BCN, including magnetron sputtering 100 and ion beam-assisted deposition (IBAD). 101 For example, welladherent BCN thin films with different compositions were grown by the reactive DC magnetron sputtering of a B4C target with different nitrogen flows.…”

“…74 95 Embedding C atoms into the lattice of BNNSs Bandgap decreased from 5.5 to 2.6 eV with the increase in C incorporation Also, high temperature stable ferromagnetic properties observed Potential for spintronic and optoelectronic devices. BCNNSs 96 One-pot synthesis BCN nanosheets (thickness of 2.2-3.4 nm) showed high adsorption capacities of 210.97 and 625 mg g À1 for Pb 2+ and Hg 2+ , respectively Potential for wastewater treatment BCN nanoflakes 97 Pyrolysis BCN nanoflakes exhibit oxidation resistance (B810 1C) B-N, C-C and C-N bonds were identified in X-ray photoelectron spectrometer (XPS) analysis 2D BCN layers 98 Solid-state route Four compositions achieved in which carbon-rich B 0.15 C 0.73 N 0.12 displayed excellent stability for 4100 charge/discharge cycles B-C-N layers 99 Microwaveassisted PECVD Modifications of the optical, electronic and transport properties of h-BN-rich and C-rich phases BCN foam 100 Modified CVD Synthesized BCN foam displayed high electrocatalytic activities for ORR compared to the Pt catalyst Also, high thermal stability (up to 900 1C) shown by BCN foam BCN foam 86 CVD BCN foam with three compositions was synthesized All showed stable thermal performance BN concentration increase led to a decrease of the electrical conductivity of the synthesized foam 78 The properties of BCNNTs depend upon wall layers, element compositions and structure alignment. Vertically aligned BCNNTs show their potential for photoelectricity and energy storage applications.…”

Nanosheet-Structured Boron Carbon Nitride Spheres as Stable Electrocatalyst Support for Oxygen Reduction Reaction

“…However, the poor electrical conductivity of BN constitutes a big obstacle for its application as electrocatalyst support for ORR. Boron carbon nitride (BCN) formed by introducing carbon atoms into the BN structure possesses much improved electrical conductivity comparing with BN and much improved chemical and thermal stability comparing with carbon [24], [25], which endows BCN the superiority for application as the electrocatalyst support. Recent reports indicate that the BCN materials possess electrocatalytic activity for ORR [26]- [28].…”
