With the de novo synthesis method, Ag(I) ions could be located inside micropores or adsorbed on the external surface of the ZIF-8 by selecting AgNO3 in water or Ag2CO3 in ammonia solution as precursors, respectively. The ZIF-8 confining Ag(I) ion exhibited a much lower constant releasing rate than the Ag(I) ion adsorbed on the ZIF-8 surface in artificial seawater. As such, strong diffusion resistance in association with the confinement effect is contributed by ZIF-8’s micropore. On the other hand, the release of Ag(I) ions adsorbed on the external surface was diffusion limited. Therefore, the releasing rate would reach a maximum not increasing with Ag(I) loading in the ZIF-8 sample.ende novo synthesis | metal-organic frameworks | silver release | ZIF-8[SDGs]SDG14journal article10.3390/ma16052040369031532-s2.0-85149837125https://api.elsevier.com/content/abstract/scopus_id/85149837125
