摘要

In light of the increasing global energy crisis and growing environmental challenges, the search for sustainable energy storage solutions has become a vital goal. This study makes notable progress by efficiently synthesizing the MoS2@MnMoO4 composite material using a straightforward two-step hydrothermal method. The synergistic interaction between MoS2 and MnMoO4 results in heterostructures that demonstrate impressive improvements in charge-storage kinetics, achieving a specific capacity of 722.5 C g− 1 at 1 A g− 1. Additionally, the asymmetric supercapacitor assembly, MoS2@MnMoO4//graphite mixed activated carbon (AC-G), delivers a strong energy density of 99.5 Wh kg− 1 at 850 W kg− 1, along with excellent cyclic stability over 10,000 cycles. Detailed characterization, including surface, morphological, structural, and elemental analyses, reveals the composite’s mesoporous nature and strong Faradic activity, both crucial for its high charge storage efficiency. These findings highlight the vast potential of MoS2@MnMoO4 heterostructures as durable and sustainable energy storage options, ready to help address energy shortages while promoting environmental sustainability for a greener future.
