Boron-doped diamond (BDD) electrodes have a wide potential window and can produce ozone by water electrolysis at high voltage. Though ozone has strong oxidative power (standard oxidation potential: 2.07 V NHE), it cannot decompose certain types of recalcitrant organic matter completely.

In this study, we fabricated a mesoporous TiO₂ thin film on a boron-doped diamond (BDD) layer by a surfactant-assisted sol-gel method, in which self-assembled amphiphilic surfactant micelles were used as an organic template. Scanning electron microscopy revealed uniform mesopores, approximately 20 nm in diameter, that were hexagonally packed in the TiO₂ thin film.

Here, oxygen-terminated lightly boron-doped diamond (BDD) thin films were synthesized as a semiconductor electron source to accelerate CO reduction. However, BDD alone could not stabilize the intermediates of CO reduction, yielding a negligible amount of reduction products.
