Assessing recent progress in MXene-based nanomaterials for oxygen evolution reactions

Trimetallic-organic framework/MXene composite as an oxygen evolution reaction electrocatalyst with elevated intrinsic activity

“…Although MXenes are vulnerable to oxidation with O 2 during electrocatalysis, which has a direct inuence on their activity and stability, the FeNiCo-MIL diamonds apparently enclose the MXene akes effectively, which potentially retards the MXene oxidation during the process. 61 However, the XPS measurement of the FeNiCo-MIL/Ti 3 C 2 composite (Fig. S7 †) aer a 24 h chronopotentiometry (CP) test indicates that the peak intensity of Ti(IV) in Ti 2p has been increased and also the C-Ti peak in C 1s is shied to higher binding energy due to the oxidation of titanium during longterm CP.…”

A Review on MXene as Promising Support Materials for Oxygen Evolution Reaction Catalysts

“…[64,65] While attempts have been made to incorporate the water-splitting performance of MXene-added catalyst compounds, previous articles have presented the role of MXene as a hybrid catalyst or as a sole catalyst, and further investigated defect-oriented MXene for enhanced catalytic properties. [69,71,74,82,83] However, within the existing literature, less emphasis has been placed on the role of MXene as a support material for OER. Therefore, this review highlights the necessity and emergence of coupling MXene support with OER catalysts.…”
