Novel perspectives of laser ablation in liquids: the formation of a high-pressure orthorhombic FeS phase and absorption of FeS-derived colloids on a porous surface for solar-light photocatalytic wastewater cleaning.

Original language description

A pulsed Nd:YAG laser ablation of FeS in water and ethanol produces FeS-derived colloidal nanoparticles which absorb onto immersed porous ceramic substrates and create solar-light photocatalytic surfaces. The stability, size distribution and zeta potential of the nanoparticles were assessed by Dynamic light scattering. Raman, UV-Vis and XP spectroscopy and electron microscopy reveal that the sol nanoparticles have their outmost layer composed of ferrous and ferric sulphates and those produced in water are made of high-pressure orthorhombic FeS, cubic magnetite Fe3O4 and tetragonal maghemite γ-Fe2O3, while those formed in ethanol contain hexagonal FeS and cubic magnetite Fe3O4. Both colloids absorb solar light and their adsorption to porous ceramic surfaces creates functionalized ceramic surfaces which induce Methylene blue degradation by the day light. The laser induced process thus offers easy and efficient way for functionalization of porous surfaces by photocatalytic nanoparticles which avoid aggregation in liquid phase. The formation of orthorhombic high-pressure FeS phase stable under ambient condition is the first example of high-pressure structures produced by laser ablation in liquid without assistance of electric field.
