Summary: Due to the diminishing energy resources and environmental pollution issues, direct methanol fuel cells (DMFCs) have gained a high profile in recent decades as a green energy generator. In this research, ultrasmall Rh nanocrystal-decorated heterostructures were designed and fabricated from Zn-based zeolites imidazolate frameworks (ZIFs) and Ti3C2Tx MXene nanosheets (Rh/ZIF-MX) via a bottom-up stereoassembly strategy. The resulting Rh/ZIF-MX nanoarchitectures exhibited superior electrocatalytic performance for methanol oxidation, surpassing traditional Rh catalysts directly supported on carbon materials.

Summary: Rational design and effective utilization of electrode materials can enhance the electrochemical performance of supercapacitors. In this study, MnO2 and CoNi layered double hydroxides (CoNi-LDHs) were sequentially deposited on a carbon cloth/MXene electrode to prepare a CC/MMCoNi electrode. The nanoarray structure of the electrode provides a large specific surface area and facilitates ion transfer and electron migration. The presence of MXene improves the conductivity of the electrode and provides more active sites for MnO2 attachment. CoNi-LDHs with a Co:Ni ratio of 1:2 shows the highest capacitance. An asymmetric supercapacitor assembled with the CC/MMCoNi positive electrode and activated carbon negative electrode exhibits excellent practical application ability and resistance to external forces.
