New Insights for Sun-Gathering Technologies
The direct integration of electrocatalysts with photovoltaic materials provides a strategy to photoelectrochemically power chemical transformations and store intermittent solar energy as fuels. However, many electrocatalytic components used or proposed for use in such assemblies also absorb visible light. This prompts the questions: to what extent does a selected electrocatalytic coating screen photons from reaching the underlying photovoltaic, do excited-state species associated with coating layers contribute to photocurrent production via mechanisms involving dye-sensitization processes, and are relatively high or low loadings of catalytic sites advantageous. Herein, we providing a general yet useful strategy for adressing thes questions and better understanding the origin of photocurrents and fuel production activities in catalyst-modified semiconductor electrodes.

Science at the Interface: Bioinspired Materials Reveal Useful Properties​ ​
​The design of sophisticated new materials is undergoing brisk technological advancement. Innovations in material science promise transformative improvements in industries ranging from energy to manufacturing.

WORK BY  WADSWORTH AND CO-AUTHORS GRACES COVER OF ACS APPLIED MATERIALS AND INTERFACES 
​

 ​Inspired by nature, where amino acid residues and soft-material coordination environments regulate the midpoint potentials of metals in proteins, the rational design of molecular interfaces provides opportunities to control the electrochemistry of metals on surfaces. Herein, Wadsworth and coauthors describe the immobilization of metallocomplexes onto transparent conductive oxide supports using molecular-based attachment strategies that enable synthetic control over the redox response of the composite electrode assemblies.

​The article describes the interplay between light absorption, charge transfer and catalytic activity at molecular-catalyst-modified semiconductor liquid junctions
. The related kinetics are modeled using steady-state and pre-equillibrium aproximations, yielding rate laws similar in form to those applied in studies invovling classic enzymatic reactions and Michaelis-Menten-type  analysis. This work forges a link between kinetic models decribing biological ensemblies and emerging molecular-based technologies for solar energy conversion, providing a conceptual framework for extracting kinetic benchmarking parameters currently not possible to establish.

ODELLA, WADSWORTH, MORA AND CO-AUTHORS PUBLISH IN JACS (Cover Article). The article, titled: Proton-Coupled Electron Transfer Drives  Long-Range Proton Translocation In Bioinspired Systems, describes the design of bioinspired molecules that employ oxidation–reduction processes to move reversibly two, three, and four protons via a Grotthuss-type mechanism along hydrogen-bonded networks up to ∼16 Å in length. These molecules are composed of benzimidazole moieties linking a phenol to the final proton acceptor, a cyclohexylimine. Following electrochemical oxidation of the phenol, the appearance of an infrared band at 1660 cm–1 signals proton arrival at the terminal basic site. Switching the electrode potential to reducing conditions reverses the proton translocation and resets the structure to the initial species.

WORK BY KHUSNUTDINOVA, WADSWORTH, AND CO-AUTHORS GRACES COVER OF ACS CATALYSIS.  ​The cover art illustrates the molecular structure of the reported catalyst, a binuclear copper(II) fused porphyrin, and the union of two protons to synthesize the chemical product, hydrogen. Under appropriate conditions, a single molecule of the catalyst produces more than 2,000,000 molecules of hydrogen per second (a rate constant among the highest reported in the literature). This work explores the concept of leveraging extended aromaticity as a strategy for breaking  unfavorable scaling relationships associated with multi-proton multi-electron redox catalysis and providing an alternative to use of electron withdrawing or donating substituents to favor electron transfer at reduced bias potentials while unfavorably altering kinetics of associated  proton transfer steps.
