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.

ODELLA, MORA, WADSWORTH, AND CO-AUTHORS PUBLISH IN JACS. The article, titled: Controlling Proton-Coupled Electron Transfer in Bioinspired Artificial Photosynthetic Relays, reports on Bioinspired constructs consisting of benzimidazole-phenol moieties bearing N-phenylimines as proton-accepting substituents designed to mimic the H-bond network associated with the TyrZ-His190 redox relay in photosystem II. In these constructs, the extent of proton translocation along the H-bond network, either ∼1.6 Å or ∼6.4 Å, can be controlled through imine substitution.

PATHWAYS TO ELECTROCHEMICAL SOLAR-HYDROGEN TECHNOLOGIES. This article condenses the perspectives of ~50 basic scientists, engineers, and social scientists, from academia, government, and industry, and reports on high-potential pathways for commercialization opportunities of solar-hydrogen technologies. By doing so, the article identifies key barriers for the deployment of these technologies both in the short term and long term. The insights provided in this perspective paper intend to contribute to defining new directions for research in the solar fuels field, and to enable future solar-hydrogen ventures that capitalize on technical advances from the scientific community.

BEILER AND COWORKERS PUBLISH IN INORGANIC CHEMISTRY. The article describes how thin-film polypyridyl surface coatings can be used to assemble cobalt porphyrin catalysts for hydrogen production onto a a gallium phosphide semiconductor. Key features of the hybrid photocathode include the use of visible light to drive cathodic fuel-forming reactions in aqueous solutions with no added organic acids or sacrificial chemical reductants.

U.S. RESEARCHERS SUPPORT "SOLAR FUELS INNOVATION ACT", prompting an initiation to expand scientific knowledge about converting solar energy into chemical energy. Specifically, supporting research about: (1) replicating natural photosynthetic processes in artificial photosynthesis processes, and (2) generating a variety of fuels produced from sunlight through artificial photosynthesis. (A photosynthetic process is one used by plants to convert light from the sun into chemical energy. Artificial, human-made photosynthesis mimics the natural process.)
DIANA KHUSNUTDINOVA AND ANNA M. BEILER RECEIVE RECOGNITION AT THE 2017 BIODESIGN FUSION RETREAT. Diana Khusnutdinova was invited to present results form her publication in Chemical Science and Anna. M Beiler received the Marie Curie Award For Best Use of Chemistry.

KHUSNUTDINOVA AND COWORKERS PUBLISH IN CHEMICAL SCIENCE. The 'Edge Article' describes a novel synthetic methodology to chemically graft metalloporphyrin catalysts to a visible-light-absorbing semiconductor with the aim of constructing an integrated photocathode for light activating chemical transformations that include converting solar energy to fuels. Characterization of a cobalt-porphyrin based assembly under simulated 1-sun illumination indicate the highest per metal site turnover frequency of hydrogen production reported to date for a molecular-catalyst-modified semiconductor photoelectrode operating at the proton/hydrogen equilibrium potential.
