“…The cyclic voltammograms of SnO 2 / CDs@MXene show that the current densities have been improved by enhancing the scan rates because of the quicker diffusion kinetics on the electrode's surface. 49 The enhanced current response at a higher scan rate (50 mV s −1 ) indicates that the rate of ion transport and interfacial Faradaic reaction kinetics were appropriate at a high scan rate. The comparable nature of cyclic voltammograms at a high scan rate also indicates an ideal capacitive nature and quicker reversible redox reaction of SnO 2 /CDs@MXene.…”

Herein, a 3D-0D-2D-ternary heterostructure nanocomposite comprising pseudocapacitive SnO 2 nanospheres (3D) and carbon dot (0D)embedded Ti 3 C 2 T x (MXene) nanosheets (2D) on Ni-foam was synthesized via a simple hydrothermal strategy for the use of positive electrodes in asymmetric supercapacitor devices. Yellow-emissive carbon dots were synthesized using the nontoxic polyphenolic precursor 2,4,6-tridihydroxybenzoic acid through a simple thermal heating method by dehydrating sulfuric acid medium through dehydration-induced carbonization. SnO 2 played a crucial role by providing reactive centers on the surface of the carbon-dot-embedded MXene, thereby significantly enhancing the capacitive performances. Encapsulation of MXene by the 3D SnO 2 nanospheres restricted the restacking tendency of the MXene nanosheets, enhancing their ability to store surface charge. Owing to its excellent morphological features, SnO 2 /carbon dots@MXene afforded superior electrochemical activities, having a specific capacitance of 1074 F/g in a three-electrode study. Moreover, the asymmetric supercapacitor device composed of the synthesized SnO 2 /carbon dots@MXene nanocomposite exhibited the maximum specific capacitance of 92 F/g at 2 A/g, with an enhanced energy density of 51.11 W h/kg. The supercapacitor device exhibited approximately 103% retention of the specific capacitance after 10,000 cycles and was able to illuminate light-emitting diode bulbs of different colors, demonstrating its practical applicability. Because of its superior electrochemical performance, the SnO 2 /carbon dots@MXene ternary nanocomposite may be a promising candidate for nextgeneration binder-free supercapacitor electrodes.

“…Owing to its exceptional chemical and physical properties, such as high oxidation resistance, excellent chemical stability, low dielectric constant, good optical properties, and remarkable mechanical strength, h-BN, a typical graphite-like material, is being explored for various applications. − These unique characteristics of h-BN have prompted ongoing research for its use as lubricating additives, reusable substrates for surface-enhanced Raman spectroscopy, luminescent materials, for oil–water separation, sewage treatment, photodetectors and resonators, micro/nano high thermal conductivity insulators, optoelectronic devices, and microwave absorption application. − Since h-BN has excellent electrical insulation capacity, low dielectric constant, and superior microwave transmission capability, it cannot be employed alone as a MAM . On the other hand, h-BN may create more interfaces inside the composites, which will lead to a greater interface and dipole polarization and improve the microwave absorption performance of the composites. , Qi and co-workers fabricated a layered-structured N-doped expanded-graphite/boron nitride hybrid nanocomposite and showed an EAB of 9.37 GHz with a matching thickness of 2.4 mm .…”

The study of electromagnetic (EM) wave absorbing materials is a natural response to ever-worsening EM wave pollution in modern days. Several nanomaterials have been explored as wideband, low-thickness, and lightweight microwave absorbing materials (MAMs) for use in both military and civilian realms but require significant improvement. This work presents the synthesis and charcaterization of in situ exfoliated boron nitride coated nickel ferrite (NiFBN) with excellent porous microstructure, using a simple auto-combustion method as well as the fabrication of a NiFBN-multiwalled carbon nanotube (MWCNT)epoxy-based lightweight, thin nanocomposite for wideband microwave absorption (X-band). With a 2 mm thick sample, the 15-NiFBN-0.75_2mm nanocomposite exhibits effective absorption bandwidth (EAB) of 3.9 GHz and −59.38 dB reflection loss minima (RL min ). Several percentages of boron nitride with nickel ferrite were synthesized using the sol−gel auto-combustion process, and the MWCNT percentage was adjusted for enhanced microwave absorption.
