“…[24,25] Even though, early BCN structures reported considerably lower capacitance, [26,27] recent optimization in the condition and enhanced techniques have allowed to express improved results. [28][29][30] Exploiting the 2D structure and high charge storage, BCN composites have been reported including polyaniline wrapped and supported BCN yielding 951 F g −1 at 2 mV s −1 [31] for graphene and MoS 2 covalently cross-linked BCN nanostructures. [32] However, the enhanced BCN nanosheet as a potential ultrahigh performance supercapacitor is yet to be discerned with novel advanced nanocomposites.…”

The 2D/2D layered materials are gaining much‐needed attention owing to the unprecedented results in supercapacitors by their robust structural and electrochemical compatibility. Here, a facile scalable synthesis of 2D/2D MXene/boron carbon nitride (BCN) heterostructure through no residue direct pyrolysis is reported. The process allows the in‐situ growth of BCN nanosheets unravelling the surfaces of MXene synergistically that provide an interconnected conductive network with wide potential window, augmented proportion of Ti sites at elevated temperature removing terminal groups enabling high pseudocapacitive activity and impressive stability. As a result, the as‐assembled MXene/BCN electrode records a high specific capacitance of 1173 F g−1 (1876 C g−1) at 2 A g−1 and an energy density of 45 Wh kg−1. Further, the fabricated solid‐state device exhibits an ultra‐high cyclability of 100% capacitive retention after 100 000 cycles. This will be an epitome for future 2D/2D heterostructures with commendable electrochemical properties as an expedient solution for energy storage applications.

“…Due to the quick depletion of non-renewable energy resources, high energy demand and environmental pollution have been addressed by focusing on stimulating interest in sustainable and renewable energy. The alarm about environmental pollution and high energy demand means that green energy and high-performance, eco-friendly energy production/storage systems are immediately required in energy technology engineering [1][2][3]. Electrocatalytic approaches are one of the most appealing and efficient storage technologies for producing high-pure fuels, high energy density, and sustainable energy sources to meet the demands of energy consumption.…”

Increasing concerns about the vulnerability of the world’s energy supply and the necessity to implement sustainable technologies have prompted researchers to develop high-performance electrocatalysts that are affordable and efficient for converting and storing renewable energy. This article reports a facile approach to fabricating two-dimensional (2D) Ge-decorated h-BN/MoS2 heterostructure nanosheets by self-assembly for multiple electrochemical applications such as supercapacitor and hydrogen evolution reactions. The organization of the physical and chemical links between the germanium modulations on the heterostructure of boron nitride/molybdenum sulphide (Ge/h-BN/MoS2) were facilitated to generate more active sites. Furthermore, the asymmetric supercapacitor of Ge-decorated h-BN/MoS2 amplified the capacitance to 558.53 F g−1 at 1 A g−1 current density and 159.19 F g−1 at 10 A g−1, in addition to a retention rate of 85.69% after 2000 cycles. Moreover, the Ge-decorated h-BN/MoS2 catalyst realized a low over-potential value, with an RHE of 0.57 (HER) at 5 mA/cm2, a Tafel value of ∼204 mV/dec, and long-term electrolysis stability of 10 h. This work may open the door for further investigations on metal-decorated heterostructures, which have a significant potential for both supercapacitor and water-splitting applications.
