SnO2 Nanosphere/Carbon Dot-Embedded Ti3C2Tx MXene Nanocomposites for High-Performance Binder-Free Asymmetric Supercapacitor Electrodes

“…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.…”

“…Figure b depicts the CV plot of SnO 2 /CDs@MXene nanocomposite at multiple scan rates (3–50 mV s –1 ). 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 . 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.…”

Influence of Exfoliated Boron Nitride for Fabrication of a Lightweight Wideband Microwave Absorbing Material

“…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 .…”
