Abstract

In one aspect, the disclosure relates to relates to heterogeneous catalysts useful for the synthesis of ammonia under microwave irradiation, processes for preparing the disclosed heterogeneous catalysts, and processes for synthesizing ammonia using the heterogeneous catalysts with microwave irradiation. In various aspects, the disclosed heterogeneous catalysts comprise: a metal selected from Group 7, Group 8, Group 9, Group 10, Group 11, or combinations thereof; a metal oxide support; and optionally a promoter material. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.
