The breakthrough in the efficiency of this perchlorate brine electrolysis has to do with the make-up of the oxygen-producing electrode. For this, the study used a variety of a mineral called <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.mindat.org\/min-29175.html\">pyrochlore<\/a>, consisting in this instance of an oxide of lead and ruthenium. Pyrochlores have a wide range of technological applications, including, as in this case, as an \u201celectrocatalyst\u201d to make electrolysis faster and easier.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Practical_options\"><\/span>Practical options<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>It remains to be seen whether MOXIE-style electrolysis of martian carbon dioxide or pyrochlore-enabled electrolysis of martian brines proves the more practical way to make oxygen on Mars. The hydrogen from brine electrolysis is a bonus that you don\u2019t get by electrolysis of carbon dioxide, and this could be used as rocket fuel as the study points out. Actually, if you want to do that, you\u2019d need to use up the oxygen as the complimentary component of the fuel. But at least that gives you a choice: breathe the oxygen or use it in a hydrogen-plus-oxygen fuel mixture.<\/p>\n<p>Neither option would be available during the several month long journey to and from Mars, for which recycling solutions would have to be found, as today on the International Space Station. These would also be important on the surface of Mars.<\/p>\n<figure class=\"align-center \">\n<figure class=\"post-image post-mediaBleed aligncenter\"><img loading=\"lazy\" decoding=\"async\" sizes=\"auto, (min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px\" alt=\"Recycling of consumables on the International Space Station.
