I'm currently working on electrocatalytic reactions and would like to better understand which systems or redox processes benefit most from RDE-based analysis.

In particular, I’m interested in:

• Reactions where mass transport plays a critical role
• Kinetic vs. diffusion control studies
• Quantitative evaluation using Koutecky–Levich (K–L) plots

Examples I have seen include HER, ORR, and CO₂RR, but I’m curious to know:

• Which reactions show reliable and interpretable behavior under RDE?
• Are there limitations when applying RDE to multi-step reactions (e.g., N₂RR or NO₃RR)?
• How useful is RDE in alkaline vs acidic media for comparing catalyst performance?

Any references, practical tips, or comparative insights would be greatly appreciated. Thank you in advance...
