Mechanism conclusions cannot rely only on activity curves, nor only on characterization spectra. Best practice: characterization points out charge behavior, activity proves the real reaction, and mutual confirmation withstands peer review.
Use the PL-SPV/IPCE1000 Steady-State Surface Photovoltage Spectrometer and the PL-TPV Transient Surface Photovoltage Spectrometer to confirm charge separation and lifetime; use the PLR-GSPR Atmospheric-Pressure Gas-Solid Photocatalytic Reaction System or the PCX-50C Discover Multi-Channel Photocatalytic Reaction System to measure real activity; then compare whether the trends agree.
Doing only activity invites "don't know why"; doing only SPV invites "irrelevant to the reaction." Always plot characterization parameters (e.g., separation efficiency) against activity metrics (e.g., H2 evolution rate) to show correlation.
Stringing "what changed in the material → how SPV/TPV changed → how activity changed → what is the causality" into one line is the most persuasive mechanism narrative.
Free consultation: Always challenged in your mechanism paper for "characterization disconnected from activity"? Perfectlight's SPV/TPV paired with PLR-GSPR/PCX-50C helps you build a standard dual-confirmation loop.

Mechanism needs both characterization (charge behavior) and activity (real reaction) to mutually confirm and withstand review.
SPV/TPV confirm separation and lifetime; PLR-GSPR or PCX-50C measure real activity; then compare whether trends agree.
Activity-only or SPV-only work gets criticized; always plot characterization parameters against activity metrics to show causality.
