摘      要：Copper oxide-loaded zeolite 4A nanocomposites(CuO-zeolite NCs)were successfully prepared by modifying zeolite 4A with CuSO_(4)aqueous solution as the copper *** 4A showed an important role in hosting copper oxide,and CuO-zeolite NCs exhibited a controlled release of copper *** patterns confirmed the appearance of new diffraction peaks of copper oxide at 35.83°and 38.83°.CuO nanosheets formed on the surface of zeolite 4A were about 30–40 nm thick over a width of 200–300 ***-zeolite NCs were primarily composed of Cu,Si,Al and O,as measured by *** 2p_(3/2) and Cu 2p_(1/2) peaks were fitted into two main peaks centered at 934.7 eV and 954.6 eV,which were attributed to Cu(II).Zeolite 4A and CuO-zeolite NC displayed reversible Langmuir isotherm(type-I)characteristics and showed maximum adsorption quantities of almost 200 cm^(3) g^(−1) at a relative pressure of 1.0 by CO_(2)adsorption-desorption *** antibacterial efficiencies of the CuO-zeolite NC were 99.4%,96.7%,and 96.8%against Pseudoalteromonas tetraodonis(***),Micrococcus luteus(***),and Shewanella putrefaciens(***),*** values showed that nano CuO-loaded zeolite 4A acted as a strong bactericide against marine ***-zeolite NCs can be further applied to marine antifouling coating.
