The invention relates to a catalytic material which is used as an optofluidic reactor, and also a method for production thereof. In this case, first a reticulated plastic foam can be fabricated which then is coated with at least one first metal or metal alloy layer. Subsequently, a photocatalytic substrate is then applied to the metal or metal alloy layer. The photocatalytic substrate eliminates bacteria, viruses and other harmful substances, as well as fine dust or fungal spores, when the optofluidic reactor is used.
