A thlummi thiamnak thar nih a almi kha a hman khawh deuh. googletag.cmd.push(function(){googletag.display('div-gpt-ad-1449240174198-2′);});
Rice University i engineer pawl nih carbon monoxide kha acetic acid (vinegar kha a thlum a almi a petu tam deuh hmanmi chemical) ah direct in an thlen i, a pehzulhmi catalytic reactor hmangin an thlen, mah nih cun a thiangmi thilri chuah khawhnak ding caah a tharchuah khawhmi electric kha ttha tein a hman khawh.
Rice University's Brown Sianginn ah chemical le biomolecular engineer hna laboratory ah electrochemical kalning nih a hlan i carbon monoxide (CO) kha acetic acid ah tlawmter an rak i zuammi buainak kha a tawlrel. Hi thil kalning hna nih thilri thianh awkah a dang lam a herh.
Pawngkam he aa remmi reactor nih nanometer cubic dar kha a biapi bikmi thlennak le aa dangmi a fekmi electrolyte ah a hman.
Suimilam 150 chung pehzulh tein laboratory riantuannak ah, hi thilri nih a chuahmi ti chung i acetic acid dat cu 2% tiang a si. Acid tthencheunak a thianhlimnak cu 98% tiang a sang, cucu carbon monoxide kha ti bantuk meihol ah thlennak tuah i zuamnak nih a chuahpimi acid tthencheunak nakin a ttha deuh ngai.
Acetic acid cu sii lei ah vinegar le rawl dangdang he hmunkhat ah kilvennak caah hman a si. Ink, rong le thuhnak caah hmanmi thilri ah hman a si; vinyl acetate chuahnak ah, vinyl acetate cu a tlangpi in a senmi hnimhnak a chuahtertu a si.
Rice sernak cu Wang laboratory chung i reactor cung ah hram bunh in carbon dioxide (CO2) in formic acid a chuah. Hi hlathlainak nih hin Wang (naite ah Packard Fellow rian pekmi) caah hrampi a chiah, amah nih hin $2 million National Science Foundation (NSF) bawmhnak a hmuh i greenhouse gas pawl kha ti bantuk meihol ah thlen khawhnak lam kawlnak pehzulh tein a tuah.
Wang nih cun, “Kan thilri pawl cu carbon pakhat a ngeimi chemical thilri formic acid in carbon pahnih a ngeimi chemical thilri ah kan thlen hna, cucu a har deuh,” tiah a ti. "Mi nih phungning tein acetic acid cu ti bantuk electrolytes ah an chuah tawn, asinain an riantuan ning a ttha lo rih i an chuahmi thilri hna cu electrolyte tthennak kong buainak an si."
Senftle nih a chimchapmi cu: “A si ko, acetic acid cu CO asiloah CO2 in sermi a si tawn lo.” "A sullam cu hihi a si: kan zorter duhmi thli thurhnawm kha kan lak i thilri ttha ah kan ser."
Dar catalyst le a fekmi electrolyte karlak ah ralring tein pehtlaihnak an tuah i, a fekmi electrolyte cu formic acid reactor in an thlen. Wang nih a chimmi cu: “A caan ahcun dar nih lam phun hnih in chemical a chuahter lai.” "Carbon monoxide kha acetic acid le zu ah a zorter khawh. Carbon-carbon pehtlaihnak a uk khomi hmai a ngeimi cube pakhat kan suai, cun carbon-carbon a kam hna. Pehtlaihnak nih thilri dang nakin acetic acid a chuahter deuh."
Senftle le a team nih an hmanmi tuaktannak model nih cube muisam kha a remh. Amah nih a chimmi cu: "Cube cung i a kam phun kha kan langhter khawh, cu hna cu a tlangpi in a tlongmi cunglei an si. CO key cheukhat kha an hrawh khawh, cucaah thilri cu lam pakhatkhat in thlen khawh a si." A cunglei hmun tam deuh nih a caan hmaan tein a hmaanmi pehtlaihnak hrawh awkah a bawmh.”
Senftler nih cun hi project hi zeitindah theory le experiment hi pehtlaihnak an ngeih awk a si timi langhternak tha a si tiah a ti. Amah nih a chimmi cu: “Reactor chung i thilri pawl fonhnak in atomic-level mechanism tiang, hi cu engineering level tampi zohchunh awk tha a si,” tiah a ti. "Molecular nanotechnology timi tlangtar he aa tlak i vawlei cung thilri hna ah zeitindah kan karhter khawh lai ti a langhter."
Wang nih a chimmi cu, a tthancho khomi system sernak ah a hnu bik kehlan cu system a fekmi tthanchoter le a kalning caah a herhmi thazaang tlawmter chinchin ding a si.
Rice University sianginn a dihmi siangngakchia Zhu Peng, Liu Chunyan le Xia Chuan, J. Evans Attwell-Welch, postdoctoral hlathlaitu, cu cauk a hruaitu bik a si.
