Mehta et al. 1 proposed that plasma-catalytic NH3 synthesis with excited N2 allows for conversions beyond thermal equilibrium. We show that this is indeed possible with experimental data for Ru-based...

In this work we study oxygen interstitial defects (O i ) in a silicontechnology-based microreactor with an integrated attenuated total internal reflection (ATR) crystal as a function of an externally applied potential by means of attenuated total internal reflection infrared spectroscopy (ATR-IR). A reduction of the 1727 cm −1 O i IR absorption band is observed with increasing potential. We evidence that this band is related to the presence of O i , which enables detection of O i by ATR-IR spectroscopy.The observed reduction with increasing potential is ascribed to an increase in temperature, due to resistive heating of the silicon.
