A light-activated catalytic process that uses gold nanoparticles to drive chemical reactions. In this application, it converts hydrogen sulfide directly into hydrogen gas and sulfur using visible light wavelengths.

Particles used to enhance the resilience of the copper catalyst and reduce the electricity required for the conversion process.

A photocatalytic mechanism where high-energy electrons generated by light-nanoparticle interaction drive chemical transformations. Used here to convert hydrogen sulfide into hydrogen gas and sulfur.

A research project at Rice University developing a light-activated method to convert hydrogen sulfide into hydrogen gas and sulfur using gold nanoparticles and visible light.

A hydrogen fuel production system that uses visible light and gold nanoparticles on silicon dioxide powder to convert hydrogen sulfide directly into hydrogen gas and sulfur. The system requires no external heating and operates in a single step.
