Photocatalytic New Technology Enables Hydrogen Production Without Carbon Dioxide Dream Solar Energy Conversion Efficiency to 50%

March 10(Fri), 2017

Yutaka Takaguchi, Associate Professor at Graduate School of Environmental and Life Science, Okayama University, and Tomoyuki Tajima, Lecturer at the graduate school, in collaboration with Yamaguchi University, Tokyo University of Science, and others have found that absorption bands of carbon nanotubes can be used to induce water splitting reaction so as to produce hydrogen.


It has been difficult to utilize carbon nanotubes as light-absorbing material for photocatalysts.  In addition, conventional photocatalysis techniques are incapable of absorbing light in the red to near-infrared region (600 to 1300 nm in wavelength), which carbon nanotubes can.  The findings, published in the U.K.’s journal Scientific Reports on March 6, are promising for use of carbon nanotubes to greatly improve the efficiency of solar energy conversion and for application of carbon nanotubes to photocatalyst-based CO2-free hydrogen production.
