A mesoporous alumina molecular sieve and a method of manufacturing a mesoporous alumina mesoporous alumina molecular sieve of the invention is produced without using traditionally used additives. Also, because the size and distribution of the pores can be controlled, the molecular sieve can be produced simply and economically, producing molecular sieve with high surface area and thermal stability. Further, a method of manufacturing an alumina nanotube by using a surfactant and a use of the alumina nanotube as a hydrogen storage material are provided.
