Exploration of the potential energy surfaces show that non\u2013doped catalyst Pt&lt;jats:sub&gt;3&lt;\/jats:sub&gt; present low selectivity towards ethylene formation, where acetylene resulting from double dehydrogenation reaction will be obtained as a side product (in agreement with the experimental evidence). On the contrary, the inclusion of Si, Ge, Sn, P or Al as dopant agents implies a selectivity enhancement, where acetylene formation is not energetically favoured. These results demonstrate the effectiveness of such dopant elements for the design of Pt\u2013based catalysts on ethane dehydrogenation.&lt;\/jats:p&gt;<\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('909','tp_abstract')\">Close<\/a><\/p><\/div><div class=\"tp_links\" id=\"tp_links_909\" style=\"display:none;\"><div class=\"tp_links_entry\"><ul class=\"tp_pub_list\"><li><i class=\"ai ai-doi\"><\/i><a class=\"tp_pub_list\" href=\"https:\/\/dx.doi.org\/10.1002\/cphc.202400095\" title=\"Follow DOI:10.1002\/cphc.202400095\" target=\"_blank\">doi:10.1002\/cphc.202400095<\/a><\/li><\/ul><\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('909','tp_links')\">Close<\/a><\/p><\/div><\/div><\/div><div class=\"tp_publication tp_publication_article tp_no_bullet\"><div class=\"tp_pub_number\">102.<\/div><div class=\"tp_pub_info\"><p class=\"tp_pub_author\"> Escayola, S\u00edlvia;  Jimenez-Izal, Elisa;  Matito, Eduard;  Ugalde, Jesus M.;  Grande-Aztatzi, Rafael;  Mercero, Jose M.<\/p><p class=\"tp_pub_title\"><a class=\"tp_title_link\" onclick=\"teachpress_pub_showhide('874','tp_links')\" style=\"cursor:pointer;\">Unveiling the quantum secrets of triel metal triangles: a tale of stability, aromaticity, and relativistic effects<\/a> <span class=\"tp_pub_type tp_  article\">Journal Article<\/span> <\/p><p class=\"tp_pub_additional\"><em>Phys.

In this way, the competition between CO and O&lt;jats:sub&gt;2&lt;\/jats:sub&gt; adsorption and the overbinding of CO is alleviated, achieving a CO poisoning\u2010free kinetic regime. Our calculations suggest that Pt&lt;jats:sub&gt;4&lt;\/jats:sub&gt;Ge&lt;jats:sub&gt;3&lt;\/jats:sub&gt; is the optimal catalyst, evidencing that alloying composition is a parameter of extreme importance in nanocatalyst design. The work relies on global optimization search techniques to determine the accessibility of multiple structures at different conditions, mechanistic studies and microkinetic modeling.&lt;\/jats:p&gt;<\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('853','tp_abstract')\">Close<\/a><\/p><\/div><div class=\"tp_links\" id=\"tp_links_853\" style=\"display:none;\"><div class=\"tp_links_entry\"><ul class=\"tp_pub_list\"><li><i class=\"ai ai-doi\"><\/i><a class=\"tp_pub_list\" href=\"https:\/\/dx.doi.org\/10.1002\/cctc.202301137\" title=\"Follow DOI:10.1002\/cctc.202301137\" target=\"_blank\">doi:10.1002\/cctc.202301137<\/a><\/li><\/ul><\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('853','tp_links')\">Close<\/a><\/p><\/div><\/div><\/div><\/div><div class=\"tablenav\"><div class=\"tablenav-pages\"><span class=\"displaying-num\">107 entries<\/span> <a class=\"page-numbers button disabled\">&laquo;<\/a> <a class=\"page-numbers button disabled\">&lsaquo;<\/a> 1 of 11 <a href=\"https:\/\/www.ehu.eus\/chemistry\/theory\/5_kt-seminars\/mat-kat-publications\/?limit=2&amp;tgid=&amp;yr=&amp;type=&amp;usr=&amp;auth=&amp;tsr=#tppubs\" title=\"next page\" class=\"page-numbers button\">&rsaquo;<\/a> <a href=\"https:\/\/www.ehu.eus\/chemistry\/theory\/5_kt-seminars\/mat-kat-publications\/?limit=11&amp;tgid=&amp;yr=&amp;type=&amp;usr=&amp;auth=&amp;tsr=#tppubs\" title=\"last page\" class=\"page-numbers button\">&raquo;<\/a> <\/div><\/div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>matcat<\/p>\n","protected":false},"author":8,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[78],"tags":[],"class_list":["post-20903","post","type-post","status-publish","format-standard","hentry","category-5_kt-seminars"],"blocksy_meta":{"has_hero_section":"enabled","hero_elements":[{"id":"custom_title","enabled":true,"heading_tag":"h1","title":"Home","__id":"q83X54JDYskBj5T6QzNj0"},{"id":"custom_description","enabled":true,"description_visibility":{"desktop":true,"tablet":true,"mobile":false},"__id":"xlmilChurmepACzSDo-Xp"},{"id":"custom_meta","enabled":false,"meta_elements":[{"id":"author","enabled":true,"label":"By","has_author_avatar":"yes","avatar_size":25},{"id":"post_date","enabled":true,"label":"On","date_format_source":"default","date_format":"M j, Y"},{"id":"updated_date","enabled":false,"label":"On","date_format_source":"default","date_format":"M j, Y"},{"id":"categories","enabled":true,"label":"In","style":"simple"},{"id":"comments","enabled":true}],"page_meta_elements":{"joined":true,"articles_count":true,"comments":true},"__id":"tOv-wdK543CqOhgWbai-N"},{"id":"breadcrumbs","enabled":false,"__id":"mBcuBDLhqAhz40yPftx3t"}],"styles_descriptor":{"styles":{"desktop":"[data-prefix=\"single_blog_post\"] .entry-header .page-title {--theme-font-size:30px;} [data-prefix=\"single_blog_post\"] .entry-header .entry-meta {--theme-font-weight:600;--theme-text-transform:uppercase;--theme-font-size:12px;--theme-line-height:1.3;}","tablet":"","mobile":""},"google_fonts":[],"version":6}},"acf":[],"_links":{"self":[{"href":"https:\/\/www.ehu.eus\/chemistry\/theory\/wp-json\/wp\/v2\/posts\/20903","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.ehu.eus\/chemistry\/theory\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.ehu.eus\/chemistry\/theory\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.ehu.eus\/chemistry\/theory\/wp-json\/wp\/v2\/users\/8"}],"replies":[{"embeddable":true,"href":"https:\/\/www.ehu.eus\/chemistry\/theory\/wp-json\/wp\/v2\/comments?post=20903"}],"version-history":[{"count":13,"href":"https:\/\/www.ehu.eus\/chemistry\/theory\/wp-json\/wp\/v2\/posts\/20903\/revisions"}],"predecessor-version":[{"id":22120,"href":"https:\/\/www.ehu.eus\/chemistry\/theory\/wp-json\/wp\/v2\/posts\/20903\/revisions\/22120"}],"wp:attachment":[{"href":"https:\/\/www.ehu.eus\/chemistry\/theory\/wp-json\/wp\/v2\/media?parent=20903"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.ehu.eus\/chemistry\/theory\/wp-json\/wp\/v2\/categories?post=20903"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.ehu.eus\/chemistry\/theory\/wp-json\/wp\/v2\/tags?post=20903"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
