Abstract

Borophene, a two-dimensional (2D) allotrope of boron, has emerged as a promising material due to its exceptional electronic, mechanical, and thermal properties. In this study, we report a facile and effective synthesis of borophene via an ultrasonic exfoliation process, enabling the formation of few-layer boron nanosheets under controlled conditions. The influence of exfoliation parameters on the yield and stability of the resulting borophene was systematically investigated. Comprehensive characterization was carried out to evaluate the morphological, compositional, structural, and thermal properties of the synthesized material. Scanning Electron Microscopy (SEM) revealed sheet-like structures with layered morphology, while Energy Dispersive X-ray Spectroscopy (EDX) confirmed the elemental composition and purity of boron. X-ray Diffraction (XRD) analysis indicated characteristic crystalline features associated with borophene phases. Fourier Transform Infrared Spectroscopy (FTIR) provided insights into bonding characteristics and surface functional groups, and Thermogravimetric Analysis (TGA) demonstrated the thermal stability of the material. The combined results confirm the successful synthesis of borophene and highlight the effectiveness of ultrasonic exfoliation as a scalable method for producing 2D boron materials. This study provides important insights into the structure-property relationships of borophene and supports its potential application in advanced nanomaterials and energy-related technologies.
