1. A reactor for producing ammonia from nitrogen and hydrogen gas with a supported catalyst, comprising:
a reactor body comprising an elongated tube having a first terminal end and a second terminal end opposite the first terminal end;
an inlet in fluid communication with the first terminal end of the elongated tube for providing the nitrogen and hydrogen gas to the reactor;
an electrical port extending into the elongated tube from the first terminal end;
an interchangeable container positioned at and removably secured to the second terminal end of the elongated tube and in fluid communication with the second terminal end of the elongated tube, wherein the interchangeable container is a separate and distinct structure from the reactor body such that the interchangeable container removably secured to the second terminal end of the elongated tube can be changed;
one or more electrodes disposed within the interchangeable container;
an electride-supported metal-containing catalyst disposed within the interchangeable container; and
an outlet for receiving product gases;
wherein the electride-supported metal-containing catalyst is disposed exclusively within the interchangeable container; and
wherein the electrical port is configured to transmit an electrical current from a power source to one or more electrodes disposed within the interchangeable container.
