Pd nanoparticles-decorated borophene nanosheets for intrinsic polarization-induced visible light photocatalysis

Abstract

The synthesis of freestanding borophene has remarkable applications in the field of catalysis. Several theoretical studies demonstrated the catalytic properties of borophene-based materials. However, its practical applications remain relatively unexplored....

Borophene nanomaterials: synthesis and applications in biosensors

“…5(b). 45 The bottom-up approach techniques include chemical vapor deposition, molecular beam epitaxy, thermal decomposition, and epitaxial growth. For example, Guoan et al synthesized thin 2D films of boron on Cu foil, as shown in Fig.…”

“…, as compared to other nanomaterials. 45 It has good chemical stability and Fermi resonance, which play a major role in conducting applications of borophene. 14 However, 2D borophene synthesis has been the major challenge for researchers; thus, they have proposed different synthesis approaches for 2D borophene, such as molecular beam epitaxy, liquid sonication, chemical vapor deposition, electrochemical exfoliation, etc.…”

“…They exhibit several excellent properties such as high Young's modulus, which provides high mechanical strength to the 2D borophene layer, 3-center 2-electron bonds, which provide electrical and thermal conductivity with different orientations of 2D borophene layers, which provide metallic anisotropy, etc., as compared to other nanomaterials. 45 It has good chemical stability and Fermi resonance, which play a major role in conducting applications of borophene. 14 However, 2D borophene synthesis has been the major challenge for researchers; thus, they have proposed different synthesis approaches for 2D borophene, such as molecular beam epitaxy, liquid sonication, chemical vapor deposition, electrochemical exfoliation, etc., as shown in Fig.…”

2D Boron Nanosheets for Photo‐ and Electrocatalytic Applications

“…Additionally, recent studies have demonstrated that electrochemical exfoliation [52,53] and mechanical exfoliation by ball milling [54] can also result in a few nanometers thick borophene. Despite being a non‐layered and non‐van der Waals material, various research groups successfully achieved freestanding borophene via different exfoliation techniques and utilized them extensively for several applications [46–49] . Some of their typical HRTEM images with characteristic d‐spacing values are presented in Figure 2.…”

“…The optical bandgap can be further tuned by introducing heteroatom/metal atoms-doping/decoration on the borophene substrate. Recently, Pratihar et al [49] enlightened a new concept called intrinsic polarization to enhance the photocatalytic performance of borophene-based heterostructures. The mechanism is illustrated in Figure 12.…”
