Technology Platforms
Our Platforms
Two field-validated material technologies addressing industrial treatment and molecular separation across gas and liquid phase applications.
Platform 01
Vox — Sulfur Treating Revolutionized
A patented, non-aqueous catalytic system converting H₂S and mercaptans to recoverable, non-hazardous products via a single-step two-electron transfer mechanism. No oxidants. No aqueous chemistry. No consumables.
Vox-Sour
H₂S Treatment
Continuous vapor-phase treatment converting H₂S directly to recoverable elemental sulfur. Validated from 250 ppm to 9,000 ppm to below detection limits.
Vox-Sweet
Mercaptan Treatment
Catalytic conversion of mercaptans (C₁–C₁₀+) in liquid hydrocarbon streams to oil-soluble mixed disulfides. Validated at 800+ ppm inlet to non-detect.
How the Mechanism Works
01
Ligand Exchange at Fe³⁺ Site
H₂S coordinates to the oxo-iron center in the [Fe₃(μ₃-O)] framework anchored to the graphene surface. Sulfide displaces a water molecule forming a stable iron-sulfide intermediate.
02
Two-Electron Transfer to Graphene
S²⁻ donates two electrons through the Fe₃O cluster to the conductive graphene surface acting as a permanent electron sink. No external oxidant required.
03
Fe–S⁰ Intermediate & H₂ Evolution
The iron center bears a bound terminal sulfur atom. Protons recombine and desorb as H₂, completing the redox cycle without external oxidative regeneration.
04
Chain Growth → S₈ Release
Successive H₂S insertions extend the sulfur chain. At n>4, disproportionation releases stable S₈ — recoverable elemental sulfur — and resets the active site.
