Advanced diamond electrochemical electrodes (ADE2).
Interní kód: ADE2 ; 2018
Technické parametry: Resistivity: 0.136 ohm.cm / Potential window in aqueous electrolyte: 2.5-2.7 V / Capacitance: ca. 11 μF.cm-2 / Active surface area per cm2: > 100 cm2 / Sample dimension: 1cm2 up to 8 inch.
Ekonomické parametry: The production cost (materials, personal, amortization, overhead) is estimated to be ca. 398 CZK (15.5 Euros) per cm2 of porous boron doped diamond electrodes. In optimized conditions, the fabrication cost would drop to ca. 105 CZK (4 Euros) per cm2. For comparison, 1 cm2 flat boron doped diamond electrodes from the company Element six costs ca. 65 Euros (excluding VAT). The implementation of the production of porous boron-doped diamond electrodres using the technology developed in this project requires an investment in equipment of ca. 11,000,000 CZK (ca. 9 MCZK for the diamond deposition system and 2 MCZK in laboratory equipment) and a minimum of 2 full time employes.

The prototype is a thick porous boron-doped diamond electrode. The novelty of this electrode: its scalable active surface area that lies in the use of a nanofiber-polymer mix template and the multistep diamond deposition process submitted for patent. They are typically deposited on conductive silicon substrates, but they can be also deposited on metals (eg. Titanium) or they can be freestanding. The standard porous boron-doped diamond electrode prototypes have an active surface area of ca. 100 time higher than the sample area together with typical extreme electrochemical properties of diamond (wide potential window and low capacitance). These electrode have potential applications in water treatment and analytical electrochemistry.
