Cr\u00e9dito: Ecoinventos.<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Suena como algo salido de la ciencia ficci\u00f3n: un grupo de investigadores de la <strong>Universidad de Cambridge y la Universidad de California en Berkeley <\/strong>afirma haber desarrollado un m\u00e9todo para fabricar combustibles limpios a partir de luz solar, di\u00f3xido de carbono y agua. La clave est\u00e1 en unas estructuras microsc\u00f3picas de cobre denominadas &#8220;nanoflores&#8221; que, integradas en una hoja artificial, podr\u00edan revolucionar la producci\u00f3n de hidrocarburos sin depender de combustibles f\u00f3siles.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">La <a href=\"https:\/\/agencia.unq.edu.ar\/\" target=\"_blank\" rel=\"noopener\" title=\"\">Agencia de Noticias Cient\u00edficas de la Universidad Nacional de Quilmes (UNQ) <\/a>accedi\u00f3 a un estudio, publicado en<strong> Nature Catalysis,<\/strong> que detalla c\u00f3mo este dispositivo combina una c\u00e9lula solar de perovskita con nanoflores de cobre para transformar el CO2 en hidrocarburos como el etano y el etileno, fundamentales en la fabricaci\u00f3n de combustibles, pl\u00e1sticos y productos qu\u00edmicos.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Para llevar a cabo la investigaci\u00f3n, los cient\u00edficos dise\u00f1aron y sintetizaron las nanoflores de cobre mediante un proceso de deposici\u00f3n qu\u00edmica controlada, logrando una estructura porosa \u00f3ptima para la cat\u00e1lisis. Posteriormente, integraron estas nanoflores en una hoja artificial y las expusieron a un entorno que simulaba la luz solar y la atm\u00f3sfera rica en CO2. Mediante espectroscopia y an\u00e1lisis electroqu\u00edmico, midieron la conversi\u00f3n de di\u00f3xido de carbono en hidrocarburos, confirmando la viabilidad del sistema aunque con una eficiencia a\u00fan limitada.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A pesar del entusiasmo, la tecnolog\u00eda todav\u00eda enfrenta grandes obst\u00e1culos. <strong>En la actualidad, la eficiencia en la conversi\u00f3n de CO2 a hidrocarburos ronda apenas el 10 por ciento, lo que significa que a\u00fan falta un largo camino antes de que esta soluci\u00f3n pueda implementarse a gran escala.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">La propuesta es atractiva: <strong>reutilizar un gas contaminante para generar combustible sin emisiones adicionales<\/strong>. Para aumentar la eficiencia del sistema, los cient\u00edficos a\u00f1adieron electrodos de nanocables de silicio que oxidan el glicerol, un residuo industrial com\u00fan. Este proceso, seg\u00fan los investigadores, es 200 veces m\u00e1s eficiente que intentos previos.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A pesar de su potencial, la producci\u00f3n de hidrocarburos sigue dependiendo casi en su totalidad de los combustibles f\u00f3siles. Si bien esta tecnolog\u00eda podr\u00eda abrir la puerta a una producci\u00f3n m\u00e1s sustentable, a\u00fan enfrenta grandes desaf\u00edos para ser viable en t\u00e9rminos econ\u00f3micos e industriales.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Con todo, por ahora, el mundo enfrenta el dilema energ\u00e9tico de siempre: la necesidad de fuentes limpias y sostenibles choca con las limitaciones tecnol\u00f3gicas y los costos de desarrollo.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<div class=\"wp-block-uagb-container uagb-block-7dcee257 alignwide uagb-is-root-container\">\n<div class=\"wp-block-uagb-advanced-heading uagb-block-21a85b96\"><h4 class=\"uagb-heading-text\">\u00daltimas noticias de la secci\u00f3n Ambiente:<\/h4><\/div>\n\n\n\n\t\t\t<div class=\"wp-block-uagb-post-carousel uagb-post-grid  uagb-post__image-position-top uagb-post__image-enabled uagb-block-e66dac42     uagb-post__arrow-outside uagb-slick-carousel uagb-post__items uagb-post__columns-3 is-carousel uagb-post__columns-tablet-2 uagb-post__columns-mobile-1\" data-total=\"20\" style=\"\">\n\n\t\t\t\t\t\t\t\t\t\t\t\t<article class=\"uagb-post__inner-wrap\">\t\t\t\t\t\t\t\t<div class='uagb-post__image'>\n\t\t\t\t\t\t\t\t\t<a href=\"https:\/\/agencia.unq.edu.ar\/?p=39256\" target=\"_self\" rel=\"bookmark noopener noreferrer\"><img loading=\"lazy\" decoding=\"async\" width=\"960\" height=\"388\" src=\"https:\/\/agencia.unq.edu.ar\/wp-content\/uploads\/2026\/09\/Nieve-rosa-Principal.jpg\" class=\"attachment-medium size-medium\" alt=\"La nieve rosa se conoce tambi\u00e9n como sand\u00eda y se debe a la presencia de microalgas (imagen: La Vanguardia)\" \/>\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<h4 class=\"uagb-post__title uagb-post__text\">\n\t\t\t\t<a href=\"https:\/\/agencia.unq.edu.ar\/?p=39256\" target=\"_self\" rel=\"bookmark noopener noreferrer\">\u00bfPor qu\u00e9 hay nieve que se ti\u00f1e de rosa y afecta al ambiente?<\/a>\n\t\t\t<\/h4>\n\t\t\t\t\t\t<div class='uagb-post__text uagb-post-grid-byline'>\n\t\t\t\t\t\t\t<\/div>\n\t\t\t\n\t\t\t\t\t\t\t\t\t<\/article>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<article class=\"uagb-post__inner-wrap\">\t\t\t\t\t\t\t\t<div class='uagb-post__image'>\n\t\t\t\t\t\t\t\t\t<a href=\"https:\/\/agencia.unq.edu.ar\/?p=39180\" target=\"_self\" rel=\"bookmark noopener noreferrer\"><img loading=\"lazy\" decoding=\"async\" width=\"960\" height=\"388\" src=\"https:\/\/agencia.unq.edu.ar\/wp-content\/uploads\/2026\/09\/secretatlas.jpg\" class=\"attachment-medium size-medium\" alt=\"Los ping\u00fcinos emperador dependen del hielo marino estable para reproducirse.
