Hydrogenation catalystsyog cov khoom uas nce tus nqi ntawm cov tshuaj tiv thaiv hydrogenation, uas koom nrog qhov sib ntxiv ntawm hydrogen atoms rau ib lub molecule.Lawv feem ntau siv nyob rau hauv cov tshuaj thiab roj av industries los hloov unsaturated hydrocarbons rau hauv ntau saturated forms.Cov hydrogenation catalysts muaj xws li hlau xws li npib tsib xee, palladium, thiab platinum, uas yog feem ntau siv nyob rau hauv daim ntawv ntawm cov hlau nanoparticles txhawb rau ib tug khoom txhawb nqa khoom.Qhov kev xaiv ntawm catalyst nyob ntawm qhov tshwj xeeb cov tshuaj tiv thaiv, nrog rau qhov kub thiab txias, siab, thiab cov reactants koom nrog.Cov catalysts kuj tuaj yeem hloov kho los ntawm kev siv cov neeg txhawb nqa lossis ligands los kho lawv cov haujlwm thiab kev xaiv.Tsis tas li ntawd, cov tshuaj tiv thaiv hydrogenation tuaj yeem ua tau raws li homogeneous lossis heterogeneous tej yam kev mob, nyob ntawm seb qhov solubility ntawm cov catalyst hauv cov tshuaj tiv thaiv sib tov.

Cov txheej txheem ntawm hydrogenation cov tshuaj tiv thaiv feem ntau yog cov txheej txheem ntau kauj ruam uas koom nrog cov adsorption ntawm cov reactants rau saum npoo ntawm cov catalyst, tom qab ntawd los ntawm kev ua kom cov reactants los ntawm kev sib tsoo thiab tsim.Qhov tseeb hydrogenation cov tshuaj tiv thaiv tom qab ntawd tshwm sim ntawm qhov chaw catalytic, ua rau ntxiv cov hydrogen atoms rau cov reactants.Cov khoom tom qab ntawd desorbed los ntawm qhov chaw thiab lub voj voog catalytic rov ua dua.

Lwm qhov tseem ceeb ntawm kev siv hydrogenation catalysts yog nyob rau hauv kev tsim cov hydrogen ua roj.Qhov no yog hu ua hydrogenation ntawm dej, uas koom nrog cov electrolysis ntawm dej los tsim hydrogen thiab oxygen.Nyob rau hauv cov txheej txheem no, catalysts yog siv los pab txhawb cov tshuaj tiv thaiv thiab ua kom nws efficiency.Platinum feem ntau yog siv los ua cov catalyst rau cov tshuaj tiv thaiv no vim nws cov haujlwm siab thiab ruaj khov.

Nyob rau hauv xyoo tas los no, tau muaj kev txaus siab los tsim kom muaj kev ruaj ntseg hydrogenation catalysts raws li lub ntiaj teb-ntau thiab tsis muaj tshuaj lom cov ntsiab lus, xws li hlau thiab cobalt, kom txo tau qhov kev cia siab ntawm cov hlau muaj txiaj ntsig.Cov catalysts no feem ntau yog npaj siv cov txheej txheem kev sib txuas ntawm cov khoom siv siab, xws li atom-txheej txheej deposition lossis nto engineering.

Zuag qhia tag nrho,hydrogenation catalystsua lub luag haujlwm tseem ceeb hauv ntau cov txheej txheem tshuaj lom neeg thiab kev lag luam, tso cai rau kev hloov pauv tau zoo thiab xaiv ntawm ntau yam ntawm cov organic tebchaw.Ntxiv rau lawv cov kev siv hauv kev lag luam roj av, lawv kuj tau siv rau hauv kev sib txuas ntawm cov tshuaj zoo, tshuaj, thiab khoom noj khoom haus ntxiv.Qhov kev loj hlob ntawm cov khoom siv hluav taws xob muaj txiaj ntsig zoo thiab muaj txiaj ntsig zoo yog qhov kev hloov pauv sai heev nrog ntau cov kev tshawb fawb zoo siab thiab kev siv dav hauv kev lag luam. ntau yam kev lag luam.
