Qhov sib txawv tseem ceeb ntawm covalent organic thiab hlau organic lub moj khaum yog covalent organic moj khaum yog cov qauv uas muaj covalent bonds whereas hlau organic moj khaum yog cov qauv uas muaj kev sib koom ua ke bonds.
Covalent thiab hlau organic moj khaum yog cov chav kawm ntawm cov tebchaw uas muaj cov khoom tshwj xeeb. Ob qho ntawm cov chav kawm no muaj cov ntaub ntawv uas tau lees paub tias yog cov khoom siv organic. Feem ntau, covalent organic moj khaum yog cov tebchaw muaj ob lossis peb-dimensional zog thaum hlau organic moj khaum yog cov tebchaw muaj ib, ob lossis peb-dimensional zog.
Covalent Organic Framework yog dab tsi?
Covalent organic moj khaum yog ob lossis peb seem ntawm cov organic. Peb tuaj yeem sau lawv li COFs. Cov khoom no tau txuas ntxiv cov qauv nrog lub tsev thaiv uas tau sib koom ua ke los ntawm covalent chemical bonds. Cov kev sib txuas no yog cov kev sib cog lus muaj zog. Feem ntau, COFs yog porous thiab crystalline lug. Ntxiv mus, cov ntaub ntawv no yog ua los ntawm lub teeb ntsiab; Feem ntau yog hydrogen (H), boron (B), carbon (C), nitrogen (N), thiab oxygen (O). Cov tshuaj lom neeg lub teeb no feem ntau tsim cov ntawv cog lus muaj zog. Qee qhov piv txwv ntawm covalent organic moj khaum muaj xws li pob zeb diamond, graphite, thiab boron nitride.

Thaum xav txog cov qauv ntawm cov khoom siv cov khoom siv sib xyaw ua ke, cov ntaub ntawv no yog cov qauv ntxeem tau nrog cov xwm txheej crystalline thiab muaj cov tsev txuas ntxiv. Cov tsev blocks no sib sau ua ke los ua ib lub sijhawm ua haujlwm. Kev sib xyaw ua ke ntawm cov tsev thaiv no tuaj yeem ua rau tsim kom muaj tus lej tsis kawg ntawm cov txheej txheem organic.
Muaj ntau yam kev siv covalent organic moj khaum xws li hydrogen cia, methane cia, sau ntau yam wavelengths thiab photons los ntawm lub teeb, tso cai rau kev tsiv teb tsaws ntawm lub zog, carbon capturing, electrocatalysis, thiab lwm yam.
Metal Organic Framework yog dab tsi?
Metal-organic moj khaum yog ib, ob lossis peb-dimensional organic solids. Nws yog ib chav kawm ntawm cov tebchaw uas muaj cov khoom sib xyaw ua ke ntawm cov hlau ions lossis pawg uas sib koom ua ke rau cov organic ligands. Qhov no yog subclass ntawm kev sib koom tes polymer cov ntaub ntawv. Qhov tshwj xeeb ntawm cov khoom siv hauv chav kawm no yog nws cov qauv ntxeem tau. Cov organic ligands hauv cov qauv no qee zaum hu ua "struts".
Formally, ib lub moj khaum cov organic organic yog kev sib koom ua ke nrog cov organic ligands uas muaj peev xwm voids. Qhov kev sib koom tes no txuas ntxiv los ntawm kev sib koom ua ke hauv ib qhov ntev thiab muaj kev sib txuas ntawm ob lossis ntau tus neeg chains uas ua rau ob lossis peb-dimensional qauv.
Daim duab 02: Hlau Organic Framework
Qee zaum, lub qhov hws nyob ruaj khov thaum lub sijhawm tshem tawm cov qhua molecules xws li cov kuab tshuaj thiab cov pores tuaj yeem rov ua dua nrog lwm cov tebchaw. Cov cuab yeej no ua rau cov hlau organic ua haujlwm zoo dua qhov chaw cia rau cov pa roj thiab, cov ntaub ntawv no tseem ceeb hauv kev ua kom huv si, kev sib cais roj, catalysis, ua cov khib nyiab, thiab ua supercapacitors.
Wat yog qhov txawv ntawm Covalent Organic thiab Hlau Organic Framework?
Qhov sib txawv tseem ceeb ntawm covalent organic thiab hlau organic lub moj khaum yog tias covalent organic moj khaum yog cov qauv uas muaj covalent bonds whereas hlau organic moj khaum yog cov qauv uas muaj kev sib koom tes. Dhau li ntawm, feem ntau, covalent organic moj khaum yog cov tebchaw muaj ob lossis peb-seem cov khoom thaum hlau organic cov ntsiab lus yog cov tebchaw muaj ib, ob lossis peb-dimensional zog.
Ntxiv mus, boron nitride, graphite, pob zeb diamond, thiab lwm yam yog cov piv txwv ntawm covalent organic moj khaum thaum 1, 4-benzenedicarboxylic acid yog ib qho piv txwv ntawm cov hlau organic moj khaum.
Hauv qab infographic qhia txog qhov sib txawv ntawm covalent organic thiab hlau organic moj khaum.
Summary – Covalent Organic vs Hlau Organic Ncej
Covalent thiab hlau organic moj khaum yog cov chav kawm ntawm cov tebchaw uas muaj cov khoom tshwj xeeb. Qhov sib txawv tseem ceeb ntawm covalent organic thiab hlau organic lub moj khaum yog tias covalent organic moj khaum yog cov qauv uas muaj covalent bonds whereas hlau organic moj khaum yog cov qauv uas muaj kev sib koom tes.
