Our Mission: To discover inexpensive and stable oxide semiconductors that can efficiently photoelectrolyze water using sunlight
- To discover stable oxide semiconductors that can efficiently photoelectrolyze water and that is economically viable
- To engage and encourage young people to take an active role in solving the global energy problem
- To provide students the opportunity to participate in real time, active scientific research
The Solar Hydrogen Activity Research Kit (SHArK) Project
Solar energy is the only option for producing the vast quantities of renewable carbon-free power needed to power the planet.
The Achilles Heel of solar energy is that the sun does not shine at night and so a method to store the energy for night and
transportation uses is needed. Producing hydrogen from sunlight and water is an ideal solution to the storage problem. The
Solar Hydrogen Activity research Kit (SHArK) Project at the University of Wyoming was established in 2008 as a spin off of
our basic research effort on solar water splitting. This project provides a unique approach to learning chemistry that engages
young people to participate in actual research to help solve the global energy problem. The goal of this project is to discover
metal oxide semiconductors that can split water into hydrogen and oxygen using sunlight. Currently, no known stable material is
capable of efficiently and inexpensively photoelectrolyzing water with visible light. There are millions of compounds that need
to be produced and tested for their ability to photoelectrolyze water. We developed inexpensive kits to enable young scientists
to participate in this endeavor. The hardware and software was developed that uses an inkjet printer, laser pointer and LEGOs®
allowing for virtually endless arrays of potential metal oxide semiconductors to be easily produced and tested.
The SHArK project provides an avenue for researchers from all disciplines of science and engineering to collaborate to help solve
the global energy crisis. In 2008, the Camille and Henry Dreyfus Foundation funded a seed proposal to create this project and currently
10 kits have been distributed to undergraduate institutions. Currently, we are part of an NSF-funded project entitled "Powering the Planet"
that focuses on solar water splitting (www.ccisolar.caltech.edu

Printing and Scanning Basics
Inkjet printers are used to print two internal standards (Fe and Cu) with 3 or 4 other metals in a combinatorial pattern that
allows for many different combinations and compositions of the metal oxides to be produced and screened at a time.
To Left: an example of screening for a promising material. Four unique ternary gradients and two internal standards were printed
according to the template that was provided.
Subsequent screening of the compositions at two different applied biases shows different photoelectrochemical properties for the
different materials (false color with yellow indicating higher photocurrent activity).
The SHArK project
is currently being coordinated by the University of Wyoming Chemistry Department in collaboration
with the University of Wyoming's School of Energy Resources (SER). This project furthers the University of Wyoming's tradition of
encouraging outreach research projects and active undergraduate research activity. Faculty and students currently conducting SHArK
research include top undergraduate institutions such as Reed, Grinnell, SUNY, Lewis & Clark, and Ithaca Colleges. The UW School of
Energy facilitates interdisciplinary academic and research programs in engineering and science, economics, and environment and natural
resources policy to address critical energy-related issues faced by our society. This project accomplishes the SER mission of outreach
by attempting to help solve the energy problem across the university, the state, and beyond. More information about the School of Energy
Resources as well as the SHArK project can be found at www.uwyo.edu/ser
