Computational modeling of trapper was attempted by using computed program taking into our account the aim and the purpose of designated modeled structure. New promising nano-trapper was synthesized by applying solution route to obtain nano-product. The synthesized trapper characterized carefully by using X-ray diffraction to clarify the internal crystalline structure of investigated acid/base trapper. Scanning electron microscopy SEM and AFM were performed to evaluate both of particle and grain sizes of synthesized trapper. Furthermore many of spectral investigations were attempted. The synthesized nano-trapper classified into three categories first one is acid gas trapper with basic nature containing urea derivatives and second one is the basic gas trapper which is alumina containing trapper. The last trapper is designated to capture amphoteric gases and fumes. Acid/base gases under investigations like CO2 and NH3 were tested via synthesized nano-trapper. The efficiency of trapping process was monitored as a function on the particle size (exposure free surface area).
