Abstract

See full text

To provide an inorganic solid material that has a hydrogen sulfide sustained releasability at ordinary temperature in the air atmosphere and is capable of being handled safely and a method for producing the same, and a method for generating hydrogen sulfide using the material. A layered double hydroxide having HS− and/or Sk2− (wherein k represents a positive integer) intercalated among layers (sulfide ion-containing LDH) is produced, and the sulfide ion-containing LDH is hermetically housed in a packaging material to provide a package. In generating hydrogen sulfide, the packaging material of the package is opened, and the sulfide ion-containing LDH is exposed to the air atmosphere to sustainably release hydrogen sulfide.
