Surface Plasmon Resonance in Atomic Layer Deposition Oxide Layers for Catalytic Conversion

PROBLEM: Plasmonic enhancement for catalytic conversion depends on the metal–dielectric interface staying clean and correctly spaced from the catalytic sites, yet an ALD oxide layer can change that spacing and can itself be altered by reaction conditions. A catalytic coating that works once may fail after regeneration if the oxide or plasmonic layer has changed, and without a versioned record the change cannot be identified. Reproducibility is therefore the central problem.

SOLUTION: Storage Copy Data Management would preserve versioned copies of each plasmon-enhanced ALD catalytic coating, linking oxide thickness, plasmonic placement, DFT prediction, isotherm validation, and regeneration history as one retrievable record. The capability would support reproducibility checks and retention so a catalytic result can be traced to the exact coating version that produced it.

EVIDENCE BASIS: DOCUMENTED — surface plasmon resonance is collective electron oscillation at metal–dielectric interfaces, with field enhancement for sensing; ALD deposits angstrom-precise conformal oxide layers; DFT predicts surface-group binding; biosorption is described by qe = (C0 − Ce)V/m and the binding reaction R−COOH + M2+ ⇌ R−COOM+ + H+.
