Energy Material Advances has recently published new research on MXene/MOF hybrid materials.
According to the paper’s author, Huan Pang, a professor at Yangzhou University’s School of Chemistry and Chemical Engineering, “the investigation of MXene/MOF hybrid materials with high electrochemical performance is important.” Right now, MXene/MOF half-and-half materials stand out enough to be noticed in energy-related fields.”
Pang provided an explanation of the reasons behind developing MXene/MOF hybrid materials.
MXenes with various adversely charged surface gatherings, right off the bat, can be utilized as a substantial substrate to help the development of MOFs, subsequently not just forestalling the collection of MOF nanoparticles and MXene nanosheets but also uncovering more accessible surface regions.
Second, the hybrids can have a shorter ion-diffusion pathway and sufficient conductive channels thanks to the highly conductive MXene framework. Thirdly, the solid interfacial associations among MXene and MOFs offer unrivaled underlying trustworthiness and strength.
“The addition of MXene effectively compensates for the chemical instability and low electron conductivity of MOFs. In turn, the implantation of MOFs can effectively resolve MXene’s severe oxidative degradation and self-stacking.”

Lastly, the hybrids may be able to adapt to a wide range of specific applications thanks to the MOFs’ variable crystal structures and morphologies. As a result, MXene/MOF composites as functional materials for high-performance electrochemical devices look promising.
“In this survey, we deliberately examined and summed up the combination techniques of MXene/MOF composites as well as the deduction cycle of MXene/MOF-determined materials. Pang stated, “Then, the important electrochemical applications of MXene/MOF composites and their derivatives, including supercapacitors, alkali metal-ion batteries, multivalent ion batteries, LSBs, water splitting, and ORR, were thoroughly analyzed and concluded.”
“The chemical instability and low electron conductivity of MOFs can be effectively compensated for with the introduction of MXene. MXene’s severe oxidation degradation and self-stacking can be effectively resolved by implanting MOFs, in turn.”
“MXene/MOF composites have better electrochemical properties (such as specific capacities, rate performance, cycling stability, Tafel slope, etc.), as numerous studies have demonstrated.” Because of the well-designed structure, strong interfacial interaction, sufficient active sites, and exoteric conductive channels, it is superior to pure MOFs and MXene. In addition, different practical MOF-determined nanomaterials have been effectively combined with MXene and convey enormously upgraded electrochemical execution.”
Pang stated, “Their application in the electrochemistry field was still in its infancy, despite many significant achievements in MXene/MOF composites and their derivatives having been published.” The major issues and perspectives of MXene/MOF composites and their derivatives were discussed for improved development in the future.”
Pang stated, “The following aspects are noteworthy.” First, make MXene/MOF composites more diverse; second, make synthetic strategies work best; third, create interactions between the faces; fourth, plan complex models; fifthly, investigate MOF derived from MXene; sixth, make devices that use energy; at long last, grasp working systems.”
“We all witnessed the significant progress that they have made in electrochemical energy storage and conversion,” Pang stated. “Although MXene/MOF composites and their derivatives face many challenges yet to be addressed,” the review, in our opinion, will contribute to a deeper comprehension of functional MXene/MOF-based composites and offer sound advice for their development in electrochemical applications in the future.”
