Process productivity, improving electrochemistry

A second liquid phase may be deliberately employed in an emulsified form to gain advantages similar to those cited earlier for organic processes. Such two-phase systems, and even two-phase enzymatic reactions, allow both the electrochemistry and organic chemistry to take place in their optimum medium. Further, the aqueous phase allows acidity to be controlled in the organic medium and the organic phase allows the desired intermediate product to be extracted to improve yields. 

The simultaneous application of ultrasonic irradiation to an electrochemical reaction which has been termed sonoelectrochemistry has been shown to produce a variety of benefits in almost any electrochemical process. These include enhanced chemical yield in electrosynthesis and the control of product distribution improved electrochemical efficiency in terms of power consumption, improved mixing, and diffusion in the cell minimization of electrode fouling accelerated degassing and often a reduction in the amount of process-enhancing additives required. In a major chapter devoted to this topic, Suki Phull and Dave Walton have attempted to cover the majority of applications of ultrasound in electrochemistry including electrochemical synthesis, electroanalytical chemistry, battery technology, electrocrystallization, electroinitiated polymerization, and electroplating. 

Electrochemistry experienced in the recent years the introduction of many in situ techniques for the purpose of improving the understanding of the electrode process at a molecular level. Among these techniques, the infrared spectroscopy plays a relevant role as a tool to study, in situ, the electrode surface. The molecular specificity permits the identification of adsorbates and reaction products and allows the study of physicochemical properties of adsorbed molecules. 

One of the most common prejudices concerning applied electrochemistry is that the crucial factor for the production costs of an electrochemical process is the cost of electricity. But capital costs are almost in all cases the dominant factor, and this should be taken into account when an electrochemical reaction is studied with a view to its industrial application. In fact, the possibilities of applications are connected with the improvements which can be achieved in the overall synthetic sequence, from the raw material to the final product. The most important goal is to cumulate several reaction steps in one this immediately improves energy... 

Developing a fundamental understanding of how catalyst function as a basis for design of improved catalysts has become one of the grand challenges in electrocatalysis. The electrochemical processes always involve multiple reaction pathways, active sites, and products and cannot be well characterized experimentally. The development of DFT in electrochemistry, as demonstrated above, makes it possible to understand the reaction mechanism at the atomic level. Such understanding allows the theoretical screening for better catalysts. 

As such, the band reported by Metters et al. aims to alleviate such problems whilst also reducing any preparatory steps required as upon the completion of the screen-printing process, the sensor requires no further treatment or modification. The mass production of such disposable microband electrodes holds great promise in electrochemistry, particularly as a base transducer for utilisation in electroanalytical sensing where the benefits of the microscopic domain of the band electrode imparting improvements in the analytical performance can be realised.
