MoO3 is a versatile two-dimensional transition metal oxide having applications in areas such as energy storage devices, electronic devices and catalysis. To efficiently utilize the properties of MoO3 arising from its two-dimensional nature exfoliation is necessary. In this work, the exfoliation of MoO3 is carried out in 2-butanone for the first time. The achieved concentration of the dispersion is about 0.57 mg·mL−1 with a yield of 5.7%, which are the highest values reported to date. These high values of concentration and yield can be attributed to a favorable matching of energies involved in exfoliation and stabilization of MoO3 nanosheets in 2-butanone. Interestingly, the MoO3 dispersion in 2-butanone retains its intrinsic nature even after exposure to sunlight for 24 h. The composites of MoO3 nanosheets were used as an electrode material for supercapacitors and showed a high specific capacitance of 201 F·g−1 in a three-electrode configuration at a scan rate of 50 mV·s−1.

Abstract Development of sustainable electrochemical energy storage devices faces great challenge in exploring highly efficient and low cost electrode materials. Biomass waste derived carbonaceous materials can be used as an alternative to expensive metals in supercapacitor. However, their application limited by low performance. In this study, the combination use of persimmon waste derived carbon and transition metal nitride demonstrated strong potential for supercapacitor application. Persimmon based carbonaceous gel decorated with bimetallic-nitride (N-NiCo/PC) was firstly synthesized through a green hydrothermal method. Electrochemical properties of N-NiCo/PC as electrode in 6 M KOH electrolyte solution were evaluated by using cyclic voltammetry (CV) and charge-discharge measurements. The N-NiCo/PC exhibited 895.5 F/g specific capacitance at 1 A/g current density and maintained 91.5% capacitance retention after 900 cycles. Hence, the bimetallic nitride-based-composite catalyst is a potentially suitable material for high-performance energy storage devices. In addition, this work demonstrated a promising pathway for transforming environmental waste into sustainable energy conversion materials.
