Insights on the Corrosion and Degradation of MXenes as Electrocatalysts for Hydrogen Evolution Reaction
Bibliographic record
Abstract
Abstract MXenes, known as the graphene‐like two‐dimensional transition metal carbides, carbonitrides, or nitrides, have been considered as promising electrocatalysts to replace benchmark Pt for hydrogen evolution reaction (HER). Despite the success in fabricating MXenes, their application in catalysis still faces great challenges. One critical drawback is the rapid corrosion and structural evolution of MXenes during storage and HER. In this work, the corrosion and structural evolution of various MXenes in air, aqueous colloidal solutions, and under HER conditions are reviewed. The degradation/structural mechanism of MXenes and effects of structural evolution on the HER activity are in dispute. Preliminary protocols are proposed for future MXene storage and design for HER application. This review provides valuable information to better prevent corrosion of MXenes before and after servicing as HER catalysts, and to interpret the obtained HER performance for MXenes in the view of corrosion/structural evolution.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
