Hydrogenation catalystsYog tshuaj uas ua kom muaj kev cuam tshuam ntau npaum li cas ntawm hydrogenation cov tshuaj, uas muaj kev sib ntxiv ntawm hydrogen atoms rau molecule. Lawv feem ntau siv nyob rau hauv kev lag luam thiab roj av roj av los hloov cov ntaub ntawv tsis muaj pes tsawg leej muaj hlau me, thiab platinum, uas feem ntau siv nyob rau hauv daim ntawv ntawm cov hlau nanoparticts txhawb nqa cov khoom siv txhawb nqa. Qhov kev xaiv ntawm catalanst nyob ntawm cov tshuaj tiv thaiv tshwj xeeb, suav nrog kub, siab, thiab cov reactants. Cov catalysts kuj tseem tuaj yeem hloov kho los ntawm kev siv cov kev txhawb nqa lossis ligands kom zoo rau lawv cov haujlwm thiab xaiv. Tsis tas li ntawd, hydrogenation cov tshuaj yuav tau nqa tawm raws li homogeneous lossis heterogeneous mob, nyob ntawm cov solubility ntawm cov tshuaj tiv thaiv nyob rau hauv cov tshuaj tiv thaiv nyob hauv kev sib xyaw ua ke.

Lub tshuab ntawm hydrogenation cov tshuaj tiv thaiv feem ntau yog ib tug txheej txheem ntau ntau uas cuam tshuam nrog cov kev ua haujlwm ntawm cov reactants los ntawm cov reactants los ntawm kev ua txhaum thiab tsim. Qhov tseeb hydrogenation cov tshuaj tiv thaiv tom qab siv nyob rau thaj chaw catalytic, ua rau ntxiv ntawm hydrogen atoms rau cov reactants. Cov khoom yog ces desorbed los ntawm nto thiab catalytic kev voj voog rov ua dua.

Lwm qhov kev thov tseem ceeb ntawm hydrogenation catalysts yog nyob rau hauv kev tsim cov hydrogen raws li roj. Qhov no yog paub txog hydrogenation dej, uas muaj feem cuam tshuam nrog cov dej hluav taws xob los ua hydrogen thiab oxygen. Hauv cov txheej txheem no, catalysts yog siv los pab txhawb cov tshuaj tiv thaiv thiab nce nws txoj kev ua tau zoo. Platinum yog feem ntau siv raws li catalyst rau qhov kev tshwm sim no vim nws cov haujlwm siab thiab ruaj khov.

Nyob rau hauv xyoo tsis ntev los no, tau muaj kev txaus siab ntau ntxiv rau kev txhim kho hydrogenation catalysts raws li lub ntiaj teb-nplua nuj, xws li hlau thiab cob cov hlau thiab cob cov khoom siv ntawm cov khoom siv hluav taws xob. Cov catalysts yog feem ntau npaj siv cov ntaub ntawv synthesis, xws li atom-txheej tso tawm lossis eng-algineering.

Zuag qhia tag nrho,hydrogenation catalystsUa si ib lub luag haujlwm tseem ceeb hauv ntau cov txheej txheem kev siv tshuaj thiab muaj rau cov txheej txheem ua tau zoo thiab kev hloov pauv ntawm cov organic sib txuas. Ntxiv rau lawv siv nyob rau hauv kev lag luam roj av, lawv kuj tau siv nyob rau hauv synthesis ntawm hydrogenation catalys yog qhov kev tshawb fawb ntau yam thiab kev siv ntau yam kev lag luam ntau yam.
