Abstract
The present disclosure discloses a ceramic material having a positive slow release effect and a method for manufacturing the same. The ceramic material comprises a hierarchically meso-macroporous structure which composition at least includes silicon and oxygen, wherein the hierarchically meso-macroporous structure includes a plurality of macropores and a wall having a plurality of arranged mesopores, and the plurality of macropores are separated by the wall; and nano-scale metal particles confined in at least one of the plurality of arranged mesopores. The nano-scale metal particles have a positive slow release effect from the at least one of the plurality of arranged mesopores. The ceramic material has a property of inhibiting growth of microorganisms or killing the microorganisms in an environment or a system containing a hydrophilic medium.
