Figure 2: Real-time manometry/UV–vis monitoring of oxygen evolution and cerium(IV) consumption.
From: Evidence for an oxygen evolving iron–oxo–cerium intermediate in iron-catalysed water oxidation
UV–vis spectra of (a) 2 -α and (c) 2 -β (solid black line) formed by the respective reactions of 1- α and 1- β (1 mM) in Milli-Q H2O at 25 °C with 3 equiv. of CAN, on addition of 75 equiv. of CAN (dotted red line) and after CAN consumption (dashed purple line). Time courses for the reaction of (b) 1- α and (d) 1- β with 75 equiv. CAN monitoring, [CeIV] (right axis, dotted blue line), and O2 evolution (left axis, solid black line). Kinetic traces for [CeIV] were monitored at 450 nm. Δ[O2] (TON) was monitored by a pressure transducer and quantified by GC-TCD.
