Abstract
A system for photocatalytically modifying a chemical composition comprising a semiconductor powder dispersed and entrapped within a layer of Pyrex glass wool interposed between two transparent plates. When a fluid containing the chemical composition flows through the glass wool and around the semiconductor powder, electromagnetic radiation impinging upon the semiconductor powder causes the chemical composition to be modified. A method for modifying the chemical composition and a method of manufacturing a panel for use in the system and method are also disclosed.
