Original Abstract Submitted

Metamaterials may be utilized to facilitate conversion of hydrogen sulfide into elemental hydrogen and elemental sulfur in the presence of suitable photocatalyst particles. Photoreactor systems utilizing metamaterials may comprise a flow-through reaction space having at least one metamaterial-catalyst surface. The at least one metamaterial-catalyst surface comprises a metamaterial surface having a plurality of resonators patterned thereon and a plurality of photocatalyst particles located upon at least a portion of the resonators, within a gap between a first region and a second region of one or more resonators, or within a gap between adjacent resonators. The plurality of photocatalyst particles comprise at least one photocatalyst effective to convert hydrogen sulfide into elemental hydrogen and elemental sulfur upon exposure to electromagnetic radiation.
