摘要： Provided is a catalyst that is free from catalyst deactivation caused by reaction of the support and exhibits good catalytic activity in an ammonia synthesis reaction in a low-temperature, low-pressure process. The present invention relates to an ammonia synthesis catalyst having a structure in which at least one of ruthenium or an oxide of ruthenium is loaded on a titanium suboxide support represented by the composition formula TiOx where x represents a number satisfying 1.5
