The goal of Subtask 2 "Artificial Water Oxidation Complex" is to develop a bio-inspired catalyst for water oxidation.

Researchers working on this subtask are trying to design a catalyst that will incorporate features of the natural  oxygen evolving complex (OEC)  via a framework of synthesized materials. Given the difficulties researchers have encountered in developing a robust water oxidation catalyst based on abundant materials and having both low overpotential and high turnover, the Center is investigating several approaches to this part of the project. Researchers at ASU and elsewhere have uncovered the structure of the peptide framework of the natural PSII water oxidation complex, although the details of the metal complex itself and its mechanism of operation still await discovery. Our knowledge and expertise are now sufficient to allow construction of an artificial oxygen evolving complex whose catalytic site is based on the natural one. We are investigating a novel design wherein DNA is used as a self-assembling framework upon which a peptide-based catalyst is constructed. Another approach is based upon design of water soluble analogs of the natural water oxidation complex. In a collaborative project, a totally artificial porphyrin-based system whose design is drawn from the natural complex is being studied. A final approach involves investigating the structure, properties and function of a natural oxygen-consuming enzyme whose active site will be used as the basis for a new type of bio-inspired water oxidation catalyst.

BISfuel, July 9, 2014 –  Deciphering the puzzles of the natural photosynthetic water oxidation mechanism empowers designers of artificial photosynthesis with knowledge to construct better water oxidation catalysts for solar fuel production. A group of Bisfuel researchers working with collaborators at the DOE free electron laser has achieved an important milestone in understanding the photosynthetic water oxidation catalytic process.

18 Feb 2014

by Jenny Green:      In a recent early online edition of Nature Chemistry, ASU scientists, along with colleagues at Argonne National Laboratory, have reported advances toward perfecting a functional artificial leaf. Designing an artificial leaf that uses solar energy to convert water cheaply and efficiently into hydrogen and oxygen is one of the goals of BISfuel, the Energy Frontier Research Center, funded by the Department of Energy, in the Department of Chemistry and Biochemistry at Arizona State University.

1 Feb 2013

BISfuel© :    A team of Bisfuel researchers led by Devens Gust, Ana Moore and Tom Moore has designed and characterized an artificial photosynthetic reaction center inspired by natural Photosystem II and comprising a highly oxidizing porphyrin linked to a biomimetic electron transfer relay and a porphyrin electron acceptor. Two articles with the results of the study have appeared in September special issue of PNAS “Chemical Approaches to Artificial Photosynthesis: Solar Fuels Special Feature” 

22 Jun 2011

A group of Center for Bio-inspired Solar Fuel Production researchers collaborating on Subtask 2 (Water oxidation catalyst) and Subtask 5 (Functional nanostructured transparent electrode materials) have found that transparent and conducting antimony tin oxide with controlled pore size incorporates DNA nanocages with high affinity and without damage. Results of the study have been published in  the June 2011 issue of ACS Nano. The study has brought the Center scientists a bit closer to a design of a transparent nanostructured electrode with entrapped functional water oxidation catalysts.

15 Apr 2011

Center researchers have developed a new DNA origami design strategy for engineering complex, arbitrarily shaped 3D DNA nanostructures that have substantial intrinsic curvatures. This strategy has been presented in a paper by Professors Hao Yan, Yan Liu and coworkers that was featured on the cover of Science for April 15, 2011.

4 Feb 2011

Professor Petra Fromme, a Principal Investigator of Subtask 2 at the Center, and members of her lab, Ingo Grotjohan and Raimund Fromme, have recently been involved in international collaboration study on time-resolved structure determination of membrane proteins. A recent breakthrough publication in Nature based on results of this study is entitled “Femtosecond X-ray protein nanocrystallography”.

DNA origami using 'tiles' not 'staples'
2 Mar 2010

The group of Yan Liu and Hao Yan has discovered a way to scale up DNA origami using tiles not staples to pin the DNA into place. Their method has great potential for providing cheap access to complicated nanostructures.
