1. A system, comprising:
an airflow passage configured to confine a flow of air and direct the flow of air toward a space; and
an air purification element positioned in the airflow passage and configured to produce a peroxide to oxidize contaminants in air flowing through the airflow passage, the air purification element comprising a layered structure including:
a peroxide-generating structure configured to produce the peroxide from a water vapor and oxygen in the air within the airflow passage, the peroxide-generating structure having a first electrode and a second electrode with an ionically conductive matrix disposed therebetween; and
a matrix containing a peroxide-activating catalyst configured to activate peroxide produced, the matrix being arranged as an outermost layer of the air purification element to allow the contaminants to contact peroxide activated by the peroxide-activating catalyst, wherein
the peroxide is produced upon application of a voltage across the first electrode and the second electrode, and
the air purification element comprises a plurality of channels for airflow and the peroxide-generating structure and the matrix containing the peroxide-activating catalyst are located in each channel of the plurality of channels.
