Water splitting to produce clean hydrogen energy by semiconductor band engineering


Project Description

To suppress or recover from the global warming, development of clean energy technology is important to research area from now on. Hydrogen is useful energy for fuel-cell cars, aircraft, etc. Since hydrogen becomes water after its combustion, it is clean energy. If hydrogen gas could be produced from natural energy such as solar light, the final clean energy cycle would be possible.Let’s develop clean energy technology together. The following topics are available for internship students.1.Photocatalysis for hydrogen generation2.Co-catalyst study for higher efficiency3.Other state-of-art topics​The students will learn and challenge electrochemical measurement, photocatalytic measurement, and various physical & chemical characterization such as SEM, Spectroscopy, XRD, XPS, gas/liquid/ion chromatography. This project needs 2-6 months to be completed. ​​​​

Kazuhiro Ohkawa
​Professor Ohkawa‘s research
interests include science
and device application of energy-conversion
phenomena toward a more sustainable future. Promising applications are solid
state lighting and artificial photosynthesis. Ohkawa has refined MOVPE technique to the point
where only his MOVPE can grow specifically designed InGaN as an essential
component to fabricate efficient yellow- amber- and red-LEDs. InGaN is environmentally benign, and will
snatch the device field by arsenides and phosphides. He is also trying to
generate clean chemical energy from light energy by using nitride photocatalyst
he invented. It is so-called artificial photosynthesis which produces not only
H2 from H2O reduction but also HCOOH, CH4 and
C2H5OH from CO2 reduction. Efficiency of
nitride photosynthesis is already greater than average of biological
photosynthetic one.

Desired Project Deliverables

​The internship students will learn photo-electrochemical knowledge on energy conversion by semiconductors from light to hydrogen clean energy. The students are expected to work full-time. The results are utilized for publications. The students attend weekly meetings with the Faculty Advisor​
