Abstract
In this contribution, we report, for the first time, on the surface bio-sulfurisation of metallic surfaces at room temperature via natural
sativum annilin
. More precisely, this bio-sulfurisation is validated on bioengineered nanostructured Cu
2-X
S surfaces using natural organosulfur compounds emitted from
Sativum allium L.
as efficient sulfurisation chemical agents. It is validated that virgin copper surfaces can be sulfurised at room temperature without adding any extra chemical or physical processes. In addition to the validation of the green sulfurisation process of the copper surface, the bioengineered Cu
2-X
S exhibited a multiscale 1-D tubular morphology with Cu
2-X
S nanotubules and nanocones. Such a nanostructured Cu
2-X
S surface exhibited an excessive optical selectivity, a superhydrophobicity response in addition to a remarkable site selective mercury adsorption.
