英文摘要Bimetal cobalt nickel phosphate covsb-1 molecular sieves with the yield of about 88 wt% have been synthesized rapidly in 4 h at 443 k under hydrothermal conditions. about 32.3 and 23.7 wt% of ammonia gases can be adsorbed by vsb-1 and covsb-1, respectively, after being activated for 20 min at 373 k. compared with the related adsorption amount of 17.5 wt% for zeolite naa, their adsorption amounts are very high, which may be due to the large pore diameters of 0.9 nm, high surface areas (ca. 134 and 156 m(2)/g for vsb-1 and covsb-1, respectively), suitable p-oh acidic activities, and a large amount of frameworks transition-metal nickels and/or cobalt coordination centers. the possible chemisorption mechanism could be deduced through the xrd patterns, ft-ir and u-v-vis spectra analytic results.
