Ammonium cerium nitrate (CAN) yog ib qho tshuaj inorganic uas siv tau ntau yam thiab tau siv dav hauv ntau yam lag luam. Ib qho ntawm cov kev siv CAN zoo tshaj plaws yog nyob rau hauv thaj chaw ntawm catalysis, qhov twg nws txhim kho kev ua haujlwm ntawm cov tshuaj catalytic hauv ntau qhov chaw.
Cov tshuaj no siv dav ua cov tshuaj catalyst hauv kev tsim cov xov paj thiab cov yas, nrog rau hauv kev tsim cov tshuaj, cov xim thiab cov khoom siv av nplaum. Nws cov khoom catalytic pab ua kom cov tshuaj tiv thaiv sai dua yam tsis muaj kev cuam tshuam rau qhov zoo ntawm cov khoom kawg.
Ib qho ntawm cov yam ntxwv tshwj xeeb ntawm ammonium cerium nitrate yog nws lub peev xwm los txhawb kev xaiv oxidation ntawm ntau yam organic compounds, ua rau nws yog tus neeg sib tw zoo tshaj plaws rau kev tsim cov organic. Nws cov haujlwm catalytic pab txhawb kev ua haujlwm redox, uas yog qhov tseem ceeb rau kev tsim ntau yam organic compounds tseem ceeb.
Kev siv CAN tsis yog tsuas yog siv rau hauv kev lag luam tshuaj lom neeg thiab kev kho mob xwb. Nws kuj tseem siv rau hauv kev tsim cov khoom siv hluav taws xob thiab ua cov khoom siv luminous. Nws cov khoom luminescent tau ua rau muaj kev tsim cov txheej txheem CAN nrog cov peev xwm siv tau rau hauv kev siv teeb pom kev zoo thiab cov zaub.
Xaus lus, cerium ammonium nitrate yog ib qho tshuaj sib xyaw ua ke uas siv tau ntau yam hauv ntau yam lag luam. Nws cov yam ntxwv catalytic, oxidizing thiab luminescent ua rau nws yog ib qho tseem ceeb hauv kev tsim ntau yam khoom lag luam. Cov tshuaj no kuj tau pom cov ntawv thov zoo hauv kev kho mob ua ib qho kev kho mob rau ntau yam kab mob. Thaum kev tshawb fawb txog cov tshuaj no txuas ntxiv mus, cov ntawv thov tshiab yuav raug tshawb pom, ua rau cov tshuaj no muaj nqis ntxiv rau kev tshawb fawb thiab kev lag luam.
Lub tuam txhab WONAIXI (WNX) tau pib tsim cov Ammonium cerium nitrate xyoo 2011 thiab tau muab tso rau hauv kev tsim khoom loj hauv xyoo 2012. Tam sim no, WNX muaj peev xwm tsim khoom txhua xyoo ntawm 2,500 tons ntawm Ammonium cerium nitrate. Peb muaj cov khoom lag luam ammonium cerium nitrate thiab cov khoom siv hluav taws xob ammonium cerium nitrate kom tau raws li qhov xav tau sib txawv.
