Investigation of NH3 and no adsorption over Cu/SAPO-34 and Cu/AlOo3 catalysts for NH3–SCR system
… (TPD) with three different conditions (NH_3, NO, combined NH_3-NO) to evaluate the adsorption of ammonia and nitric oxide. Cu/SAPO-34 catalyst has shown higher ammonia adsorption capacity compared to Cu/Al_2O_3 catalyst. The Cu/SAPO-34 adsorption is enhanced due to the strong acidity and high …

Molecular oxygen adsorbates at a Au/Ni(111) surface alloy and their role in catalytic CO oxidation at 70 - 250 K
… at 77 K, in stark contrast to dissociative adsorption on Ni and no adsorption on Au surfaces. Molecular 02 adsorbates on the Au/Ni(111) surface alloy are identified by their 0=0 vibrational modes at 790, 850 and 950 cm-', measured by electron energy loss spectroscopy. Possible Ni adsorption …

A Window into Selective Catalytic Reduction: a RAIRS Study of NO and NH3 on Cu{311}
… between the bare Cu{311} surface with NO and NH3,individually and co-adsorbed using reflection-absorption infrared spectroscopy (RAIRS). In addition to the bare Cu{311} surface, the interaction of NO and NH3 with the various oxygen phases of the Cu{311} surface phases was also studied. …

Molecular recognition using nanotube-adsorbed polymer complexes
… the selective detection of single nitric oxide (NO) molecules using a specific DNA sequence of d(AT) 15 oligonucleotides, adsorbed to an array of near infrared fluorescent semiconducting single-walled carbon nanotubes (AT₁₅-SWCNT). While SWNT suspended with eight other variant DNA sequences show …

Poisoning and Sulfation on Vanadia SCR Catalyst
… pores. Activity assessments of commercial monolith catalysts with various exposures (time and fuel type) indicated that catalyst deactivation involves fouling, pore plugging, and poisoning. Different mechanisms may dominate depending on exposure time, catalyst properties, and combustion …

Application of synthetic molecular sieve zeolites and silica gel towards the separation of sulfur dioxide from combustion gases
… sulfur dioxide from combustion gas streams has not been realized. Sulfur dioxide adsorption capacities were obtained for equilibrium (non-flow) and dynamic flow conditions. Sulfur dioxide adsorption on the molecular sieves could be described by a modified Langmuir expression of the form …

Biphasic Cellulose Acetate/Rtil Membranes And Functionalized Graphene Adsorbents For Natural Gas Processing: Experimental And Molecular Simulation Studies
… membranes (silms), biphasic membranes, and nanoporous graphene (npg) and graphene oxide (npgo) membranes are studied. Biphasic membranes are proposed to overcome silms issues for gas separation. The major issues with silms are low room temperature ionic liquid (rtil) content and instability at …
