October 2010 ABSTRACT
Stable, Molecular Water Oxidation and Water Splitting Catalysts
Dr. Craig Hill, Emory University
There is considerable international interest in developing effective (fast, high-yield, high-quantum yield, selective, and extremely stable) systems to generate solar fuels. The 3 unit operations for solar water splitting and carbon fuel production via H2O reduction of CO2, namely the photosensitizer (PS), the water (and/or CO2) reduction catalyst (WRC), and the water oxidation catalyst (WOC) all must be more effective than the systems reported to date.
To this end, we report the first stable and molecular WOCs. They also have the fastest catalytic turnover rates and by design, many of their properties (charge, potentials, etc.) are alterable. Defect polytungstates (polyoxometalates or ?POMs? based on W) are the multi-valent ligands that make our WOCs possible. The first reported POM-based WOC was [{RuIV 4O4(OH)2(H2O)4}(?-SiW10O36)2]10- (Angew. Chem., Int. Ed. 2008, 47, 3896), which was subsequently shown to catalyze visible-light-driven water oxidation (J. Am. Chem. Soc. 2009, 131, 7522) and its energetics and mechanism were studied in detail (J. Am. Chem. Soc. 2009, 131, 17360). However, Ru will very likely be prohibitively expensive, thus we turned to a broad spectrum evaluation of POM complexes with multiple proximal 3d transition metal centers. In this process, we determined that the tetra-cobalt complex, [Co4(H2O)2(PW9O34)2], was very effective and exhibited the highest turnover rate per metal of any WOC and was the fastest homogeneous WOC by a factor of 6 or so (Science, 2010, 328, 342). Eight lines of evidence establish that this Co4 POM is stable under catalytic turnover conditions.
We have since developed another soluble, stable, tunable, multi-cobalt POM-based WOC that is faster still. In conjunction with development of these WOCs, we are also developing carbon-free (and thus air-stable) POM-based water reduction catalysts (WRCs) and photosensitizers. In very recent unpublished work, we have achieved good photocurrents and see large catalytic effects on photocurrents from water oxidation in photoelectrochemical cells and other structures. All these results will be discussed in detail. The remaining challenges we face on development of these new WOCs and WRCs and their integration with tris(2,2?-bipyridine)ruthenium(II)-based and other PS units will be outlined.
We thank the Office of Basic Energy Sciences of the US Department of Energy for support.
October 2010 Speaker
Dr. Craig Hill, Emory University
Dr. Craig Hill, Goodrich C. White Professor of Chemistry, conducts research in inorganic, catalytic and nanomaterials chemistry and related areas. His recent work has developed major breakthroughs in artificial photosynthesis - the focus of intense research around the world in the quest for sustainable, clean energy. His lab has developed the fastest, carbon-free molecular water oxidation catalyst (WOC) to date, considered a crucial component for generating clean hydrogen fuel using only water and sunlight.
Hill's honors include being elected a fellow of the American Association for the Advancement of Science, a Distinguished Fellow of the Victorian Institute of Chemical Sciences and Chair of the National Science Foundation Workshop in Inorganic Chemistry for 2007-2009.

National Chemistry Week 2010
Behind the Scenes with Chemistry
NCW Poster Contest : "Behind the Scenes with Chemistry"
The Western Carolinas section of the American Chemical Society (WCACS) is proud to participate in the ACS sponsored NCW Poster Contest. Specific details on the contest are available through the attached PDF or by directly linking to the ACS NCW site (www.acs.org/NCW). WCACS will accept up to four (4) entries per grade category per school. The grade categories, as indicated on the contest form, are K-2, 3-5, 6-8 and 9-12. Entries must be received by Monday October 18th to be considered for the national competition. As an example, an elementary school with K through 5th grade students could submit a total of 8 entries: 4 entries from students in the K-2nd grade and 4 entries from students in 3rd –-5th grade. Local section volunteers will judge the submissions based on the criteria indicated in the contest guidelines and will forward one winning entry in each of the four grade categories to the national competition. Feel free to contact John Kaup (john.kaup@furman.edu) if you have any questions.
Submission should be sent to the following address:

WCACS sponsored National Chemistry Week (NCW) Outreach Events:
WCACS is reaching out into our local community to celebrate National Chemistry Week and could use your help! Take a look at the various events being organized and contact John Kaup (john.kaup@furman.edu) or Laura Wright (laura.wright@furman.edu) if you are interested in volunteering for one or more of these opportunities. In each case, we have a game plan for delivering demos, activities and/or hands-on lessons, but the section could use a host of volunteers to provide additional creative ideas and/or help with delivering these events.
Westgate Mall, National Chemistry Week Activities
Date: Saturday October 30th
Time: 11 AM – 4 PM
Place: Westgate Mall, Spartanburg, in the Center Court.
An annual favorite delivered by the chemistry students at Spartanburg area schools. A variety of hands-on science activities will be available for families visiting the mall. Volunteers are needed to help with this annual event.
Asheville, National Chemistry Week Activities
Date: Saturday October 23rd
Time: 10 AM – 4 PM
Place: Health Adventure, Pack Square (Downtown Asheville) (click here)
The UNC Asheville Student Members will be leading the Saturday Science Day in a National Chemistry Week demonstration of hands-on experiments. Volunteers are requested for assistance with the experiments, safety, surveying participants, set up and break down. 1-2 hour shifts can be arranged during the day.
NCW School Event (and fund raiser)
Dates: Tuesday – October 26th
Time: 6:00 – 8:00 p.m. - could also use help before (set-up) and after (clean-up)
Place: Stone Academy of Communication Arts (115 Randall Street, Greenville, SC) (click here)
For the fourth straight year we will be providing an educational and entertaining opportunity at Stone Academy. This event is being held in conjunction with students and teachers from Wade Hampton High School as part of their Spirit Week. This event will also serve as a fund raiser for a local after school program (Frazee Dream Center). A series of hands-on activities will be provided in the gym (or classrooms) while a large demo show (provided by Roper Mountain Science Center?s Science on Wheels) will be provided in the cafeteria. Event will be open to the public and numerous volunteers are needed to staff this event.
Roper Mountain Science Center (RMSC) Event: 2nd Saturday fun at RMSC (click here)
Date:November 13th
Time: 9:00 a.m. until 2:00 p.m.
Place: Roper Mountain Science Center (402 Roper Mountain Road, Greenville, SC 29615)
WCACS will again be partnering with RMSC for their 2nd Saturday event to offer a variety of fun and educational hands-on science activities. Come join us for the fun as students explore chemistry concepts through a variety of both NCW themed and other familiar hands-on activities. Typically have over 1000 attendees for their 2nd Saturday programs. Volunteers are needed to help deliver the hands on activities that are being planned and perhaps help with the large demo show. We will offer at least 6 ongoing hands-on activities throughout the day. Volunteers can come for the whole day or select one of the following time slots: Early (9:00 a.m. -11:00 a.m.), Mid (10:30 – 12:30) or Late (12:00 – 2:00). In addition, we plan to also offer three 45 minute chemistry demo shows (on the hour at 10, 11 and 12) in the large auditorium (seats 200 +).
Bilingual (Spanish/English) Science Fun
We have 250 Spanish language Celebrating Chemistry pamphlets to distribute. If you have an idea about how to utilize these for an event or know of a group to which you could distribute these let us know.
If you would like to volunteer to assist with any of these events contact John Kaup or Laura Wright.
