“…Recently, Jasuja et al. [ 92 ] reported the synthesis of TiB 2 sheets using the exfoliation method. In this work, they mixed bulk TiB 2 into an aqueous solution of H 2 O 2 and the resulting mixture was stirred at ambient conditions to obtained TiB 2 sheets.…”

Since the discovery of borophene in 2014, tremendous efforts have been invested in exploring its synthesis methods as well as in exploiting the potential applications. Borophene has been progressively used in the field of chemistry, material science, nanotechnology, and condensed matter physics. This review discusses the physical (thermal, electronic, superconductive, and mechanical) and chemical properties of borophene followed by the advances in the experimental synthesis strategies and finally its applications in the field of environment and energy. Initially, the potential of borophene as a heterogeneous catalyst is discussed in CO2 reduction, N2 fixation, hydrogen evolution and oxygen evolution reactions followed by its use as a potential material for hydrogen storage, supercapacitors as well as its use as an anode material in batteries. Finally, a detailed summary followed by an outlook on the future potential of borophene as a remarkable material for environment and energy applications is presented.

“…Since the TiB 2 -NS are larger than the precursor TiB 2 powder, it is assumed that the TiB 2 undergoes initial dissolution followed by prenucleation of clusters to assemble as nanosheets through non-classical recrystallization. [27] This process introduces additional oxygen functional groups, as evidenced in EDX spectra (Inset Figure 1a). The silica substrate accounts for the large Si peak and a fraction of the oxygen peak.…”

“…[26] In an unconventional approach, we provide a novel and scalable non-classical recrystallization procedure for the synthesis of TiB 2 -derived nanosheets with high-yield. [27] Such dissolution recrystallization-based synthesis methodology is scarcely reported for battery application and that it holds potential for scaling up towards large-scale industry applications.…”

Metal borides when subjected to dissolution and recrystallization exhibit a tendency to grow preferentially in lateral dimensions and form nanosheets. Such derived nanosheets exhibit unusual properties that can potentially be used in energy conversion and storage applications. Here we report boride-based nanosheets derived from titanium diboride through a scalable one-pot chemical approach as a sodium-ion battery anode material. The half-cell with TiB 2 -derived nanosheets (TiB 2 -NS) as anode delivers an initial discharge capacity of 252 mAh g À 1 at 0.1 A g À 1 , and appreciable cycling stability is achieved at 1 A g À 1 current density. Further, a sodium-ion full cell assembled with TiB 2 -NS as anode and sodium vanadium phosphate/carbon as cathode is demonstrated. The full cell delivers an energy density of 111 Wh kg À 1 at a power density of 500 W kg À 1 . Being the first report of its kind, our study exemplifies the rich potential that the TiB 2 -NS deliver as an anode material upon nanoscaling and substantiates the theoretical prediction on using transition metal boride-based anode material for sodium-ion battery.

“…The potential tunability prompts the possibility of engineering boron surfaces of nanoscale and 2D systems with specifically tailored properties—for instance, for use in coatings, composites, electronic materials, or device applications 43 , 44 . Likewise, the diversity of binding configurations due to the presence of surface disorder could be an important tool for realizing multifunctional catalytic applications 31 , 45 .…”

Layered boron compounds have attracted significant interest in applications from energy storage to electronic materials to device applications, owing in part to a diversity of surface properties tied to specific arrangements of boron atoms. Here we report the energy landscape for surface atomic configurations of MgB2 by combining first-principles calculations, global optimization, material synthesis and characterization. We demonstrate that contrary to previous assumptions, multiple disordered reconstructions are thermodynamically preferred and kinetically accessible within exposed B surfaces in MgB2 and other layered metal diborides at low boron chemical potentials. Such a dynamic environment and intrinsic disordering of the B surface atoms present new opportunities to realize a diverse set of 2D boron structures. We validated the predicted surface disorder by characterizing exfoliated boron-terminated MgB2 nanosheets. We further discuss application-relevant implications, with a particular view towards understanding the impact of boron surface heterogeneity on hydrogen storage performance.
