et \u00e9tude de leur application dans l\u2019adsorption et la d\u00e9tection des pollutions de l\u2019eau et la capturCette th\u00e8se vous emm\u00e8ne dans un voyage passionnant \u00e0 travers la chimie supramol\u00e9culaire et les cadres m\u00e9tallo-organiques (MOF), en abordant les d\u00e9fis mondiaux du traitement de l\u2019eau et de la production de carburant solaire. L\u2019eau et l\u2019\u00e9nergie sont des ressources vitales, mais elles sont confront\u00e9es \u00e0 des d\u00e9fis li\u00e9s \u00e0 la croissance d\u00e9mographique, au changement climatique et \u00e0 la pollution.

Water and energy are vital resources, but they face challenges from population growth, climate change and pollution. This thesis proposes a new solution using MOFs, porous materials composed of metal ions and organic bonds with a high specific surface area and adjustable functionality. The thesis introduces a new Zr-MOF in the form of a hollow sphere with an N-oxide functional group that has a high adsorption capacity for dye molecules. With regard to solar fuel production, the thesis explores the conversion of N2 to ammonia under solar irradiation by modifying the electronic structure of a Zr-MOF through the formation of a heterojunction. Throughout this scientific journey, the thesis investigates MOF structures, adsorption kinetics, thermodynamics and the complex mechanisms underlying nitrogen fixation and CO2 conversion.<\/p>\n<\/div><\/section>","protected":false},"excerpt":{"rendered":"","protected":false},"author":20,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[318],"tags":[],"class_list":["post-62881","post","type-post","status-publish","format-standard","hentry","category-these-2023"],"_links":{"self":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts\/62881","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/users\/20"}],"replies":[{"embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/comments?post=62881"}],"version-history":[{"count":0,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts\/62881\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/media?parent=62881"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/categories?post=62881"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/tags?post=62881"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
