Tohoku Univ. Technology : Production method of carbon material: T13-160
Large amount production of carbon material at relatively low temperature
CVD and electrochemical method are known to product carbon material such as carbon nanotubes or graphenes. In the CVD process, carbon material is produced at high temperature in order to decompose the precursor molecule that provides the carbon. The hydrothermal electrochemical method can produce carbon material at lower temperature than CVD method. However, the amount of carbon material produced by this method is small. This invention is to enable to produce large amount of carbon material at relatively low temperature. In this production method, carbon material is produced from aqueous solution in which the temperature is 100℃ or higher, the pressure is greater than 1 atm, and soluble carbonaceous precursors by a hydrothermal electrochemical method. The produced carbon material can be composed of at least one of diamond like carbon, carbon nanotube, graphene, diamond. This invention is to enable to produce large amount of carbon material at relatively low temperature.

Company information
The revenue generated from technology transfer is reinvested as new research funding for universities and researchers, and is utilized to create further research outcomes. To ensure the smooth operation of this cycle, known as the "Intellectual Creation Cycle," we will vigorously promote technology transfer. The types of seeds we handle include patents, know-how, databases, and programs. We have established a collaborative framework by signing basic technology transfer agreements with the following universities (as of June 1, 2025): Tohoku University, Hirosaki University, Iwate University, Akita University, Fukushima University, Yamagata University, Tohoku Gakuin University, Iwate Medical University, Fukushima Medical University, Aizu University, Miyagi University, Hokkaido University, Muroran Institute of Technology, and Showa Medical University.
