MXenes are an emerging class of two-dimensional transition metal carbides and nitrides with metallic conductivity and hydrophilic surfaces. The discovery of MXenes has opened new possibilities for developing advanced hybrid composites for energy storage and conversion applications. This review summarizes recent advances in developing MXene-based hybrid composites, including their synthesis, characterization, and electrochemical performance. The heterostructure of MXenes with nanocarbons, metal oxides, polymers, and other nanomaterials can overcome the limitations of pristine MXenes and lead to enhanced lithium/sodium-ion storage, pseudocapacitive performance, and electrocatalytic activity. Various fabrication techniques have been employed to synthesize MXene composites with controlled nanostructures, morphology, and interfacial properties. Characterization by microscopy, spectroscopy, and electrochemical methods has shed light on structure-property relationships in these materials. As electrode materials, properly designed MXene hybrids have achieved high specific capacity, excellent rate capability, and long-term stability. The review also discusses strategies for further improving MXene composite energy storage performance, as well as emerging applications such as thermoelectrics and photocatalysis. Continued research to understand interfacial effects and optimize MXene heterostructures holds promise for developing next-generation energy storage technologies.

“…However, due to its inferior electrical conductivity and decreased availability of proactive edge sites to the nano sheet stacking dissociation energy barrier, MoS2 catalytic activity is severely constrained. Likewise, high-activated water to solve these shortcomings, a variety of techniques have been tried, including designing the crystallinity and morphology, linking heterogeneous materials, indicating increased active sites, promoting electron movement and lowering the initiated water dissociation energy barrier [14][15][16][17][18]. The majority of the materials utilized to decorate MoS2 currently are 2D carbon compounds, which are noble metals.…”

The photocatalytic activity and oxygen evolution reaction (OER) of MoS2 and silk graphene (silk G) composite synthesized using supercritical fluids and chemical vapor deposition (CVD) methods were investigated for their potential application in photocatalysis. This material was subjected to characterize by XRD, TEM, SEM and FTIR techniques to demonstrate that MoS2/silk G composite still existed in the supercritical fluids methods obtained MoS2 & MoS2/silk G. The optical features of MoS2 was improved by introduction of silk G, which inturn caused shift in band gap from 1.65 to 1.85 eV. Within visible region, creation of high electron-hole pairs is possible by adequate band gap modifications. The fast movement of photo-induced charge carrier can be enhanced by silk G as they decrease the recombination activity. Additionally, the MoS2/silk G shows high oxygen evolution reaction with low Tafel slope of 157.2 mV dec-1 and low overpotential of 603 mV at a current density of 10 mA cm-2. The present study signifies that with addition of silk G in the MoS2 host improved the photocatalytic activity by 13% and electrocatalytic activity by nearly 5% compared to bare MoS2 nanoparticles.

The rational development and synthesis of renewable nanostructured materials hold significant importance within the realm of energy storage applications. In this study, the quaternary chalcogenide of Cu2FeBiS4 was fabricated using a facile solvothermal method and evaluated for its performance in Oxygen Evolution Reaction (OER) and Supercapacitor applications. The material underwent characterization employing various analytical techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDX), X-ray photoelectron spectroscopy (XPS), and Raman analysis. Cu2FeBiS4 demonstrates an improved super-capacitive performance, exhibiting an outstanding specific capacity (Cs) of 1530 F g–1 at 2 A g–1. The admirable electrochemical activity is mainly due to the synergistic effect of mixed metal sulfide nanostructure that can escalate the rapid diffusion of ions and electrons, which is beneficial to the electrode/electrolyte contact area, thereby boosting the rate of charge transfer. Additionally, Cu2FeBiS4 exhibits a commendable energy density of 43.17 Wh kg− 1 at a power density of 327.87 W kg− 1, accompanied by a retention rate of 96.2% after 1000 cycles. As a result, the Cu2FeBiS4 electrode developed in this study is evinced to be a promising electrode material for high-performance energy storage devices. Moreover, Cu2FeBiS4 demonstrates proficient electrocatalytic properties for the oxygen evolution reaction, displaying a minimal overpotential of 202 mV versus the reversible hydrogen electrode (RHE) at 10 mA cm− 2 and exhibiting operational stability for up to 10 hours.
