1. A purification system for purifying an incoming stream by transforming carbon dioxide provided in the incoming stream, the purification system comprising:
an ionizing purifier comprising a substrate and an active coating, supported by the substrate and comprising a piezoelectric material selected from the group consisting of aluminum nitride, aluminum phosphate, barium titanate, bismuth titanate, gallium nitride, gallium phosphate, lithium niobate, lithium tantalate, lithium tetraborate, tourmaline, and triglycine sulfate;
a flow guide configured to direct the incoming stream toward the active coating of the ionizing purifier while controlling average pressure that the incoming stream exerts on the active coating; and
a temperature controller configured to change temperature of the active coating of the ionizing purifier.
