Vacuum adsorption was employed to synthesize platinum/polyethylene terephthalate (PET) samples with greatpotential for indoor air quality improvement application. Pt nanoparticles (PNPS) were loaded onto surface of non-wovenfabric composed of polyethylene terephthalate (PET) and with high air permeability. High activity was sought for the Pt/PETcatalyst by investigating the effects of hexadecyl trimethyl ammonium bromide (CTAB) on PNP sizes and PET fibersurfaces. The prepared samples were characterized by XRD, SEM, TEM, TG, FTIR and XPS analysis. The results indicatedthat Pt/PET samples were successfully fabricated, and a formaldehyde conversation of 70.8 % was obtained within 150 minat 35 oC using Pt/PET with 0.6 wt% Pt loading. This research provided a facile method for depositing Pt onto PET fibers(non-woven fabric), and the catalytic activities of the resulting composite Pt/PET materials indicated them to be promisingfor applications to indoor air remediation.
