a RH < 1% (zero air) and b RH = 40% for the PCN-250 samples. c RH < 1% (zero air) and d RH = 40% for PCN-250(Fe2Co), ZZU-281, MIL-100(Fe), α-Fe2O3, Co3O4, CoFe2O4, and activated charcoal. e Varied RHs for PCN-250(Fe2Co). Other conditions for all the above tests: 0.03 g catalyst diluted with 0.2 g quartz sand, concentration of O3 = 1 ppm, flow rate = 1 L min−1, room temperature. f O3 test strips used in the tests under humid condition (RH = 40%) and the color scale.
