Abstract

During the electrocatalytic CO₂ reduction reaction, the faradaic efficiency of products seriously deviates from 100% due to the misjudgment of outlet flow, especially at industrial-level large current density. In this work, several modified equations and internal standard methods are recommended to calibrate the thermal mass flowmeter and establish benchmarks for CO₂ reduction performance assessment.
