“…Even an enzymatic alternative has been described [13][14][15], since organic sulfides (thioethers, R-S-R ) can be selectively oxidized to the corresponding sulfoxides and sulfones under very mild conditions with the help, for example, of BDS (biodesulfurization) [14,15] catalyzed by enzymes such as oxygenases. However, the industrial applicability of enzymatic BDS has not yet been obtained, since the enzyme sources are limited and the costs are too high [13]. Not necessarily BDS leads to sulfur elimination from sulfur-containing organic molecules.…”

This paper describes the oxidation of inorganic sulfide to sulfate, minimizing the formation of elemental sulfur. The described catalytic reaction uses dilute hydrogen peroxide at nearly neutral pH values in the presence of a bioinspired, heterogenized, and commercial ferriporphin. A substantial increase of the percentage of sulfide converted to sulfate is obtained in comparison with the yields obtained when working with hydrogen peroxide alone. The biomimetic catalyst also proved to be a much more efficient catalyst than horseradish peroxidase. Accordingly, it could be suitable for large-scale applications. Further studies are in progress to drive sulfate yields up to nearly quantitative.

“…Recently, also metalloporphins have been suggested as catalysts for removal of thioethers [13,17,18]. These macrocycles represent a very versatile class of redox catalysts, being able to oxidize different recalcitrant organic compounds, under quite mild operational conditions [19][20][21][22][23].…”
