Zeolite is a micro porous aluminosilic mineral that has a wide surface. Its wide surface causes zeolite to be commonly used as an adsorbent. Zeolite X is included in the Faujasite structure and usually binds sodium cations. Cations bound to zeolites can be exchanged for other cations, such as transition metal cations. Transition metal cations such as [Ag(NH3)2]+ are commonly used to detect aldehyde groups or commonly known as Tollens reagents. This study aims to synthesize composite adsorbent zeolite X / silver oxide and zeolite X / copper oxide through Tollens reaction. Composites characterized using scanning electron microscope showed that the composite surface was coarser than the surface of zeolite X. The material used as a model for adsorption was ammonia gas. The resulting composites are of three types based on the stages of zeolite addition in the synthesis process, namely after the addition of a precursor (composite 1), after addition of NH4OH (composite 2), and after heating (composite 3). The resulting composite can increase the adsorption of ammonia by up to 2 times than zeolite X.
