Summary of the technology

Researchers at the Korea Institute of Energy Research (KIER), have designed a unique catalyst support preparation technology. This innovative catalyst support preparation method provides a catalyst-support made of a lightweight composite material capable of adsorption and filtration, and which possess superior intrinsic properties in terms of surface area, porosity, and physical strength.

Description of the technology

Catalyst supports are the materials, usually a solid with a high surface area, to which a catalyst is deposited. Recent research into catalysts has led to the development of innovative catalyst support materials, which have large surface areas and cheap to prepare by simple synthetic process. Researchers at the Korea Institute of Energy Research (KIER), have designed a unique catalyst support preparation technology. This innovative catalyst support preparation method provides a catalyst-support made of a lightweight composite material capable of adsorption and filtration, and which possess superior intrinsic properties in terms of surface area, porosity, and physical strength.

Research on the benefits of sophisticated catalyst-supports is limited. Research considering the use of cellulose fibres from botanic sources as a catalytic support has not been performed domestically (South Korea) or abroad. However, preliminary research has confirmed the incredible value of cellulose fibres for use as catalyst supports, specifically in comparison with conventional catalyst supports, such as mesoporous carbon, activated carbon, and carbon black. What’s more, cellulose-based catalyst supports have the advantageous benefit of being both ecologically friendly, biodegradable and economically viable as hybrid energy material alternatives.

Carbon-based nanotubes or graphene are a common category of electrode catalyst, this is due to the superior electrical conductivity of carbon, specific surface area, hydrogen storage performances and high absorption properties. Research into these nanocarbon materials has been predominantly concerned with carbon synthesis, this research has highlighted issues regarding the difficulty encountered when carbon nanotubes or graphene are attempted to be mass produced for large-scale projects. Accordingly, this new procedure for, ‘Cellulose fibre-based catalyst support’ preparation, has been designed as a suitable alternative capable of fabricating high-performance cellulose fibre catalyst supports that can support a variety of nano-metal catalysts (e.g. platinum, palladium, cobalt, nickel, etc.).

Catalyst support using cellulose fibre’ method:

The present invention provides a nano-metal-supported catalyst which reduces catalyst preparation cost. This technology comprises a method of preparing a non-metal-supported catalyst and follows 3 distinct steps:

  • Step 1: Preparation of the Cellulose Catalyst Support:

The preparation of the cellulose includes (a) splitting cellulose into individual on a micrometre scale and cutting the split to a predetermined length and (B) carbonizing the cut cellulose .

  • Step 2: Growth of Carbon Nanotubes:

This stage supporting a catalyst metal for growing carbon nanotubes on the surface of the carbonized cellulose-catalyst-support and supplying a carbon source to the surface of the cellulose catalyst supported by the catalyst metal for growing carbon nanotubes.

  • Step 3: Supporting Nano-Metal Catalyst on Carbon Nanotubes:

Pre-treatment for supporting the nano-metal catalyst and supporting the catalyst on the surface of the carbon nanotubes, grown on the surface of the cellulose catalyst support.

This advanced technology procedure for catalyst support production provides for the creation of a nano-metal-support catalyst, such as a cellulose catalyst support, whereby carbon nanotubes can be grown directly on the catalyst support.

This new procedure for, ‘Cellulose fibre-based catalyst support’ preparation, has been designed as a suitable carbon nanotube alternative capable of fabricating high-performance cellulose fibre catalyst supports that can support a variety of nano-metal catalysts (e.g. platinum, palladium, cobalt, etc.). The ‘Cellulose fibre-based catalyst support’ preparation method minimises the intrinsic limitations suffered during attempts to mass produce carbon-based catalyst supports, and benefits from improved economic and environmental viability.
