Chemisorption yog adsorption uas cov lwg me me ntawm adsorbate raug hloov pauv, sib pauv, lossis sib koom nrog cov atoms (lossis cov lwg me me) rau ntawm qhov chaw khoom los ua cov adsorption tshuaj sib khi. Vim yog qhov tsis zoo ntawm lub zog sib dhos ntawm cov khoom saum npoo, cov atoms rau saum npoo feem ntau muaj qhov seem uas tseem tshuav qhov khi muaj peev xwm. Thaum cov pa roj molecules tsoo tawm nrog cov khoom nto, cov hluav taws xob sib hloov, hloov lossis sib faib nrog cov atoms saum npoo av los ua ib qho adsorption tshuaj sib khi. nyhuv.
Chemisorption yog ceg tseem ceeb heev hauv kev tshawb fawb ntawm cov khoom saum npoo. Nws muaj cov ntawv thov tseem ceeb hauv catalysis (tshwj xeeb tshaj yog heterogeneous catalysis), corrosion, electrolysis, crystallography, metallurgy, thiab metallurgy. Cov neeg tshawb fawb txog kev siv tshuaj lom neeg kuj tseem ntxov dua, tab sis vim yog cov kev txwv ntawm kev sim, kev tshawb fawb thaum ntxov tsuas tuaj yeem nyob ntawm theem pib. Vim tias qhov kev tshawb xav tsis tuaj yeem paub tseeb los ntawm kev sim, kev txhim kho thaum ntxov ntawm kev tshawb fawb chemisorption tau qeeb. Tom qab xyoo 1960, vim muaj kev txhim kho thiab paub tab ntawm lub xeev cov khoom siv dag zog thiab kev loj hlob sai ntawm ntau yam ntsuas hluav taws xob, thev naus laus zis nqus cov tshuab thiab muaj feem cuam tshuam rau cov nplaim thiab cov tshuab zaj duab xis, ntau lub zog tsom, huab hwm coj tsom, kev sib txawv ntawm cov ntsuas thiab cov tshuab tsom me me. txuas ntxiv kom tshwm sim thiab txhim kho, ua rau tib neeg los tshawb txog qhov tshwm sim ntawm cov tshuaj adsorption los ntawm atomic thiab qib theem. Raws li qhov tshwm sim, kev tshawb fawb ntawm chemisorption tau tsim kho sai sai. Hauv cov tswv yim, cov kab lus ntawm cov qauv tau tsim muaj. Hauv cov kev sim, ntau qhov ntau ntawm cov ntaub ntawv sim.
Kev tshawb fawb ntawm cov tshuaj adsorption tuaj yeem muab faib ua peb yam: kev tshawb pom loj heev, kev tshawb xav micro, thiab lub hom phiaj xav. tsom rua kev qhia txog kev siv tshuaj adsorption los ntawm qhov kev xav me me, vim tias nws tuaj yeem ua rau tib neeg to taub cov tshuaj adsorption cov tshuaj tiv thaiv los ntawm qhov tob tob, yog li kev tshawb fawb hauv thaj chaw no tsis tsuas yog qhov tseem ceeb theoretical, tab sis kuj tseem ceeb heev qhov tseem ceeb.
