Additionally, incomplete cracking of ammonia leads to regulatory challenges in nuclear and fusion power, where tritiated ammonia (NT\n                    <jats:sub>3<\/jats:sub>\n                    ) emissions are strictly controlled. Therefore, we report the use of low\u2010temperature ammonia dehydrogenation catalysts (3%Ru\/1%Y\/12%K\/Al\n                    <jats:sub>2<\/jats:sub>\n                    O\n                    <jats:sub>3<\/jats:sub>\n                    ) in a palladium alloy H\n                    <jats:sub>2<\/jats:sub>\n                    permeation membrane for quantitative conversion of ammonia into hydrogen and nitrogen at industry\u2010relevant conditions. This catalytic membrane reactor system achieved an astonishing effluent concentration of\u2009&lt;1\u2009ppm at 450\u00b0C under a 100% NH\n                    <jats:sub>3<\/jats:sub>\n                    stream, which is far beyond the 99.6% conversion target required for the adoption of ammonia as a vehicle fuel. The low\u2010temperature ammonia dehydrogenation catalyst was tested in a packed bed reactor with NH\n                    <jats:sub>3<\/jats:sub>\n                    and ND\n                    <jats:sub>3<\/jats:sub>\n                    to both elucidate the reaction mechanism and to quantify the kinetic isotope effect of the membrane reactor. The rate\u2010limiting step at temperatures relevant to the palladium membrane are isotope independent, indicating that the isotopologue content will not modify the desired reaction kinetics. By reducing emissions to below\u2010trace levels with no additional separation, this work provides a path to greatly simplified and miniaturized ammonia cracking processes.\n
