Boron-containing Silicate-1 molecular sieve catalyst, preparation method thereof and method for preparing caprolactam

The invention relates to a boron-containing Silicate-1 molecular sieve catalyst, a preparation method thereof and a method for preparing caprolactam. The preparation method comprises the following steps: a, mixing a silicon source, a boron source, a structure-directing agent, an organic template agent and water under a mixing condition to obtain a colloid mixture; b, under a hydrothermal crystallization condition, carrying out hydrothermal crystallization treatment on the colloid mixture to obtain a crystallized product; c, carrying out washing and separation treatment on the crystallized product, so as to obtain the boron-containing Silicate-1 molecular sieve, and d, under a roasting condition, carrying out roasting treatment on the boron-containing Silicate-1 molecular sieve, so as to obtain the boron-containing Silicate-1 molecular sieve catalyst. According to the method, the catalytic performance of the catalyst can be improved, and stable cyclohexanone-oxime conversion rate and caprolactam selectivity ca
