The invention relates to a one-dimensional nano-wire VPI-8 molecular sieve and a synthesis method thereof. The technical problem to be solved by the present invention is to provide a VPI molecular sieve having one-dimensional nano-wire morphology and being not previously reported in the literature, and a corresponding molecular sieve synthesis method. According to the present invention, the pore channel orientation and the morphology control are important in the field of molecular sieve synthesis; and the VPI-8 molecular sieve with the aspect ratio of more than 100 is creatively synthesized, and the nano-wire VPI-8 molecular sieves form the fluffy agglomerate structure with the diameter of 40-100 [mu]m, such that the porosity of the molecular sieve is effectively increased, the adsorptioncapacity and the adsorption ability are enhanced, and the one-dimensional nano-wire VPI-8 molecular sieve has good application prospects in the fields of traditional catalytic reactions, photocatalytic reactions and the like.
