Nano (Graphite and Copper) Coated Coupon Quasi-R®

Description

Nano-graphite and Nano-copper particle mixture, i.e., surface protrusions (particles) on stainless steel or copper coupon.  Patented Process.  Please contact MHI is a different mix or different elements are required.

Product for Sale:  Test coupon 1cm x 1cm  304 stainless or Copper coupon with nanometer deposits of nano-graphite and nano-copper. The nano-graphite is a mixture of double-walled, single, and amorphous carbon. Nano copper is copper nanoparticles.   The average size of nano copper is about 50-100 nm.  Graphite tube and amorphous graphite content is about 20-100 nm.

Copper is pure 99.99% copper.

Use of Product:  Sample to test catalyst efficacy for alcohol conversion – with support substrate of stainless steel or copper.  The substrate coupon is about 1″ x 1″ and about 1 mm thick.  The coating thickness is ~500nm nominal with the range discussed above.

The particles are attached but may also be wiped under abrasion.  The total coverage of porous particles is about 300nm-900 nm thick coating on the substrate.  High porosity.  The picture shows the approximate coverage of copper/CuO/Carbon and TEM of the peeled-off carbon nanotube surface.  The composition of the coating/substrate is mostly C/Cu and substrate material. Nitrogen and Oxygen will also be present. Hot nitrogen atmosphere particulate is deposited on the surface.  Nitrogen content in solids is about ~1 wt% nominal.

The picture shows the approximate coverage and TEM of a peeled-off graphite/carbon nano-tube type. Variations are possible from coupon to coupon.

The product (nano-coating) is expected to contain approximately 50% by volume of copper and carbon phases on the surface, with porosity and other elements like nitrogen and oxygen. However, not all phases have been identified.

Please indicate whether a Copper substrate or a 304 or 316  Stainless Steel substrate is desired if offered.   Please add this information to the remarks during checkout.
