“…Photochemical reactions were performed using a 300 W, high-pressure Xe arc lamp (Oriel Instruments). The beam was passed through an infrared filter, a collimating lens, and a filter holder equipped with a 415 nm band-pass filter. Samples were prepared in a 1 cm path length quartz cuvette (Starna) that was placed in a temperature-controlled cuvette holder (Quantum Northwest) maintained at 20 °C with a circulated water bath. The solvent consists of a CO2-saturated mixture of acetonitrile (CH3CN) and triethanolamine (TEOA) in a 5:1 volumetric ratio, in which TEOA acts as both a sacrificial electron donor and a source of protons. [Ru(bpy)3]Cl2 (1.0 mM) was used as a photosensitizer, which is in a 10-fold excess with respect to the [Rh(R-bpy)(Cp*)Cl]+ catalyst. Samples were saturated with CO2 via directly bubbling CO2 through the solution mixture for 10 min…”
