摘要:
A powder for sustained release of a gas including a core containing a molecular sieve, and a layer containing an acid releasing agent on an outer surface of the core. The core and the layer are substantially free of water, and the core is capable of generating and releasing a gas after hydrolysis of the acid releasing agent.
