A metal substrate is fabricated and coated with a catalyst for ozone conversion of atmosphere passing through the substrate. A plurality of aluminum foil sheets that have been slit, stretched and twisted into a plurality of regularly repeating channels having geometrically shaped openings are serially positioned one on top the other to form a foil stack with channel openings partially blocked by channel walls of overlying foil sheets. Thicker covers with openings at the top and bottom of the stack form a sandwich and the sandwich pleated to form corrugations in a flexible but rigid sandwich substrate. The channel walls are coated with an ozone depleting catalyst which the ozone atmosphere contacts to remove ozone as the ozone atmosphere travels through the stack construction.

1. An ozone substrate for heat exchange units comprising:a plurality of metal foil plies positioned one on top of the other to form a stack; each foil ply having a plurality of interconnected ribbons forming walls of a channel and comprising a plurality of channels adjacent one another, each channel having geometrically shaped openings and the plies stacked so that channel walls of overlying plies partially block channel openings of overlaid plies; a metal cover on each side of said stack to form a sandwich, said cover thicker than said foil plies, spanning said plies and having cover openings formed therein for fluid communication with channel openings in said stack; and, at least one of said plies having an ozone depleting substance applied to the channel walls thereof for removing ozone from ozone atmosphere as it passes through said sandwich.
