“…Thus, the exploration of mixed transition metal oxides presents a promising avenue through which the supercapacitor technology can be advanced. Recently, metal molybdates, such as CoMoO 4 , NiMoO 4 , and MnMoO 4 , have demonstrated outstanding electrochemical performances over single component oxides [8][9][10]. In particular, cobalt molybdate (CoMoO 4 ) has become highly attractive due to its structural properties and extraordinary capacitance [7].…”

MXene has emerged as a highly promising two-dimensional (2D) layered material with inherent advantages as an electrode material, such as a high electrical conductivity and spacious layer distances conducive to efficient ion transport. Despite these merits, the practical implementation faces challenges due to MXene’s low theoretical capacitance and issues related to restacking. In order to overcome these limitations, we undertook a strategic approach by integrating Ti3C2Tx MXene with cobalt molybdate (CoMoO4) nanoparticles. The CoMoO4 nanoparticles bring to the table rich redox activity, high theoretical capacitance, and exceptional catalytic properties. Employing a facile hydrothermal method, we synthesized CoMoO4/Ti3C2Tx heterostructures, leveraging urea as a size-controlling agent for the CoMoO4 precursors. This innovative heterostructure design utilizes Ti3C2Tx MXene as a spacer, effectively mitigating excessive agglomeration, while CoMoO4 contributes its enhanced redox reaction capabilities. The resulting CoMoO4/Ti3C2Tx MXene hybrid material exhibited 698 F g−1 at a scan rate of 5 mV s−1, surpassing that of the individual pristine Ti3C2Tx MXene (1.7 F g−1) and CoMoO4 materials (501 F g−1). This integration presents a promising avenue for optimizing MXene-based electrode materials, addressing challenges and unlocking their full potential in various applications.
