The application of solid electrolyte reactors for methane oxidation to co-generation of power and chemicals could be interesting, mainly with the use of materials that could come from renewable sources and abundant metals, such as the [6,6′- (2, 2′-bipyridine-6, 6′-diyl)bis (1,3,5-triazine-2, 4-diamine)](nitrate-O)copper (II) complex. In this study, we investigated the optimal ratio between this complex and carbon to obtain a stable, conductive, and functional reagent diffusion electrode. The most active Cu-complex compositions were 2.5 and 5% carbon, which were measured with higher values of open circuit and electric current, in addition to the higher methanol production with reaction rates of 1.85 mol L–1 h–1 close to the short circuit potential and 1.65 mol L–1 h–1 close to the open circuit potential, respectively. This activity was attributed to the ability of these compositions to activate water due to better distribution of the Cu complex in the carbon matrix as observed in the rotating ring disk electrode experiments.

“…Additionally, this method may interrupt the reaction as changing the condition in the headspace may affect the activity in solution. Rather than sampling by hand repeatedly throughout the hours long reaction, Hanan’s group developed a reaction sampling mechanism, which is operated by an Arduino computer and routes samples in real time to a GC for measurement. ,,,− A very similar system has also seen use by Beller and co-workers particularly for the exploration of cobalt based PSs. − These systems are described as using a constant flow of argon into the reaction vessel with an outflow directly into the GC. By this method, the headspace remains a consistent composition and does not substantially change in pressure.…”

Photocatalytic hydrogen (H2) evolution, particularly though water reduction, presents an enticing alternative to current fossil fuel intensive methods of hydrogen production. While this field has been active for decades and advances have been made, it has been limited to serial experimentation due to the solar-mimicking lamps used and data collection techniques. With the democratization of machine and instrument design through the ever-decreasing prices of computers and sensing equipment, paired with the availability of high-power light emitting diodes (LEDs) as viable replacement light sources, reactor design has seen significant changes in recent years. After the advent of the first LED-illuminated parallel reactors for gas evolving photocatalytic reactions, a host of research groups around the world have matched the design and used their own creative means of studying H2 evolving reactions in parallel. Here we report select cases of research utilizing parallelized reactors for light-driven H2 evolution, highlighting the benefits of parallel and high-throughput experimentation. Lastly, changes to reactor design and sensing methodology, specifically how colorimetric measurement enabled the development of a 108-well parallelized reactor, are described, and these state-of-the-art reactors are compared to alternative, nonparallelized approaches using serial, robotic automation.
