“…A more detailed characterization of gas evolution processes is additionally of great importance for the optimization of electrochemical Cl 2 production, which consumes approximately 1% of the electrical energy used in the world annually. 5 Scanning electrochemical microscopy (SECM), e.g. using the sample generation-tip collection mode (SG-TC), is a straightforward technique for acquiring detailed information about the properties and local electrocatalytic activity of gas evolving electrodes.…”

A new concept for the localized characterization of gas evolving electrodes based on scanning electrochemical microscopy (SECM) is suggested. It offers information about the spatial distribution of the predominant locations, which represent the most active catalytic sites, and dynamic characteristics of gas-bubble departure. The knowledge about gas-bubble departure is critical for the assessment and development of new electrode materials for energy applications.

“…For each product, an idealized working voltage is assumed based on the equilibrium cell voltage determined from the Nernst equation at 298 K; overpotentials are ignored which will significantly underestimate the input power required. The half-cell reactions and corresponding redox potentials for each process − ,− are provided in Table S1 of the Supporting Information. For comparison of different electrochemical or photoelectrochemical processes, the ratio of the net product value to the moles of transferred electrons required per mole of product ( z ), Faraday’s constant ( F ), and the cell potential ( E cell ) is used to obtain the net product value per unit energy input: …”

The economic potential for commodity chemical production using sunlight is examined using a general comparative analysis method. The market values and feedstock prices together with basic thermodynamic constraints are used to evaluate the solar-to-chemical conversion potential for selected products using four different solar conversion pathways. Potential products are compared using several metrics including the net value of products per unit of energy input [$/kWh] and annual value of products per unit of solar exposed area [$/m 2 -year]. Low-volume, high-value chemical products such as iodine and tellurium would provide the greatest economic potential for a solar conversion process whereas high-volume, low-value products including hydrogen and methane would have tremendous challenges in generating sufficient revenue to pay for the required capital costs. Artificial photosynthesis research might be better served if the focus were to be first finding some (or any) reasonably valuable product that could be produced economically using sunlight before attempts are supported to make low-value chemical products such as hydrogen and hydrocarbons.

“…Aluminum metal is refined by electrolysis of its molten ore at a carbon electrode and produces metric tons of aluminum each year. 27 As an exemplar of a scaled synthetic electro-organic reaction, adiponitrile is produced on a large scale from the electrochemical dimerization of acrylonitrile and is used in the production of nylon-6,6. 28 However, in the pharmaceutical industry, electrochemistry is in the very earliest stages of adoption.…”

An electrochemical method for the green and practical synthesis of a broad range of substituted isoxazoline cores is presented. Both aryl and more challenging alkyl aldoximes are converted to the desired isoxazoline <i>via</i> an electrochemically enabled regio- and diastereoselective reaction with electron-deficient alkenes. Additionally, <i>in-situ</i> reaction monitoring methods compatible with electrochemistry equipment have also been developed in order to probe the reaction pathway. Supporting analyses from kinetic (time-course) modeling and density functional theory support a stepwise, radical-mediated mechanism, and discounts hypothesized involvement of closed shell [3+2] cycloaddition pathways.
