Si un material barato y abundante cumple la misma función, el costo de fabricar combustible limpio podría bajar. Para un país con sol, viento y agua como la Argentina, eso puede convertirse en energía a precio razonable. Sin embargo, el hallazgo todavía es de laboratorio y falta comprobar que funcione a escala industrial.","quienFirma":"Publicado en ACS Applied Nano Materials","confianza":"revisado","consulta":{"pregunta":"¿Qué energía debería priorizar la Argentina?"}},"sello":{"hash":"861639576dda07ef53b7957d38dd2ab884b4e177a671d7cb1cbaf0c32f8a5084","sello":"a4a58eca8480f72da75571dda4de69b174d0e1d3e6b58c452b5950df3606949c","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6587494,"aleatorio":"d20982c338d1a84c550da77057a0b1cdf8e039036f2238d8c5404abc8225e460","tiempo":"2026-10-26T23:04:00.000Z"},"nist":{"cadena":2,"pulso":2000940,"salida":"6904EEF310D53B3F67615AA7AC97EE4ABA4F4D3C8E66EBB69EEF02C78566ECD4DDDC115CEDA9E567B5270BE421B1CBDF8B2090FB575734D82EFF1FC64D0FDA16","tiempo":"2026-10-26T23:03:00.000Z"},"noAntes":"2026-10-26T23:04:00.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 26 23:04:13 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Water into fuel: The new nanomaterial that could upgrade green hydrogen","descripcion":"Generating hydrogen without releasing carbon dioxide sounds simple: pass electricity through water, split water molecules and generate green hydrogen. The hard part is the electrocatalyst. The best ones rely on platinum, ruthenium and iridium, which are scarce and expensive. We wanted to know whether a small amount of iron and nickel oxides, anchored on carbon nanofibers grown by chemical vapor deposition the right way on the right scaffold, could do the job instead. Our results are published in ACS Applied Nano Materials.","pubDate":"Mon, 26 Oct 2026 19:00:03 EDT","url":"https://phys.org/news/2026-10-fuel-nanomaterial-green-hydrogen.html"},"indexado":"2026-10-26T23:03:56.303Z"}}
