Hydrogenation catalystszvinhu zvinowedzera mwero wekuita kwehydrogenation, izvo zvinosanganisira kuwedzerwa kwemaatomu ehydrogen pamorekuru. Izvo zvinowanzoshandiswa mumakemikari uye petroleum industries kushandura unsaturated hydrocarbons mune mamwe mafomu akazara.Common hydrogenation catalysts inosanganisira simbi dzakadai nickel, palladium, uye platinum, iyo inowanzoshandiswa nenzira yesimbi nanoparticles inotsigirwa pane yakasimba inotsigira zvinhu. Sarudzo yecatalyst inoenderana nemamiriro ekuita, kusanganisira tembiricha, kudzvanywa, uye zvinobatika zvinobatanidzwa. Izvo zvinokonzeresa zvinogona zvakare kugadziridzwa kuburikidza nekushandiswa kwevanosimudzira kana ligands kuti vagadzirise basa ravo uye kusarudza. Mukuwedzera, hydrogenation reactions inogona kuitwa pasi pehomogeneous kana heterogeneous mamiriro, zvichienderana nekunyungudika kweiyo catalyst mumusanganiswa wekuita.

Iyo nzira yehydrogenation reactions inowanzoita nhanho dzakawanda-nhanho dzinosanganisira adsorption yezvinopindurwa pamusoro peiyo catalyst, inoteverwa nekushandiswa kweiyo reactants kuburikidza nekutyora kwechisungo nekuumbwa. Iyo chaiyo hydrogenation reaction inobva yaitika pane catalytic surface, zvichiita kuti maatomu ehydrogen awedzere kune anogadzirisa. Zvigadzirwa zvinobva zvasvibiswa kubva kumusoro uye iyo catalytic cycle inodzokorora.

Kumwe kushandiswa kwakakosha kwehydrogenation catalysts kuri mukugadzirwa kwehydrogen sehuni. Izvi zvinozivikanwa se hydrogenation yemvura, iyo inosanganisira electrolysis yemvura kuti ibudise hydrogen uye oxygen. Mukuita uku, ma catalysts anoshandiswa kufambisa maitiro uye kuwedzera kushanda kwayo. Platinamu inowanzoshandiswa sechinhu chinokonzeresa kuita uku nekuda kwekuita kwayo kwakanyanya uye kugadzikana.

Mumakore achangopfuura, kwave nekuwedzera kufarira mukugadzira inogadzika hydrogenation catalysts yakavakirwa pasi-yakawanda uye isina-chepfu zvinhu, zvakaita sesimbi necobalt, kuderedza kutsamira pamatare anokosha. Aya macatalyst anowanzo gadzirirwa achishandisa epamberi zvinhu synthesis matekiniki, senge atomu-layer deposition kana pamusoro peinjiniya.

Pakazara,hydrogenation catalystskuita basa rakakosha mumakemikari akawanda nemaindasitiri maitiro, zvichibvumira shanduko inoshanda uye yakasarudzika yeakasiyana siyana emakomponi. Pamusoro pekushandisa kwavo muindasitiri yepetroleum, inoshandiswawo mukugadzira makemikari akanaka, mishonga yemishonga, uye zvinowedzerwa zvekudya.Kugadzirwa kweanoshanda uye anochengetedza hydrogenation catalysts inzvimbo inokurumidza kubuda ine mikana yakawanda inonakidza yekutsvagisa uye maapplication mune yakakura. siyana maindasitiri.
