Redoxprocesser

Redoxprocesser denotes a class of devices, reactors, or models designed to perform and control redox reactions in a purposeful way. The term is a neologism used to describe systems that drive oxidation and reduction events, including electrochemical reactors where electrode potentials govern reactions, catalytic redox systems that shuttle electrons with mediators, or software models that simulate redox kinetics.

Principles underlying redoxprocessors include regulation by electrode potential or current, the use of redox mediators to transfer electrons between species, and monitoring via redox potential (Eh) and pH. The Nernst equation relates species concentrations to potential, while mass transport and reaction kinetics determine overall rates and selectivity. Design choices affect which species are oxidized or reduced, how fast, and under what energy cost.

Designs range from conventional electrochemical reactors with controlled potential to redox flow devices that use liquid electrolytes and membranes, including redox flow batteries for energy storage. In chemical processing, redoxprocessors enable selective oxidation or reduction steps, while in water treatment they can remove contaminants through targeted redox transformations. They are also explored in metal recovery, synthesis, and environmental remediation.

Advantages of redoxprocessors include tunable selectivity, modularity, rapid response to control signals, and the potential to couple reactions with separation processes. Challenges encompass energy requirements, electrode fouling or degradation, mediator stability, and management of byproducts or side reactions. Ongoing research focuses on material performance, reactor design, and integrated systems to improve efficiency and scalability.
