Tetrakis (triphenylphosphine) palladium cas 14221-01-3 chaw tsim tshuaj paus nqi

1. Kev ua haujlwm siab

Precious hlau catalysts muaj xws li dispersed nano-scale precious hlau hais nyob rau hauv kev txhawb nqa nrog high nto cheeb tsam xws li carbon, silica, thiab alumina.

2. Kev xaiv

Cov nano nplai hlau hais tau yooj yim adsorb hydrogen thiab oxygen hauv qhov chaw.Cov hydrogen los yog oxygen yog nquag heev vim nws dissociative adsorption los ntawm d-electron tawm ntawm lub plhaub ntawm precious hlau atoms.

3. Kev ruaj ntseg

Cov hlau muaj txiaj ntsig zoo ruaj khov.Lawv tsis yooj yim tsim oxides los ntawm oxidation.Cov oxides ntawm cov hlau tseem ceeb yog, ntawm qhov tod tes, kuj tsis ruaj khov.Cov hlau zoo nkauj tsis yooj yim yaj hauv cov kua qaub lossis alkaline.Vim tias muaj thermal stability siab, cov hlau muaj txiaj ntsig zoo catalyst tau siv los ua cov khoom siv hluav taws xob ua kom huv si.
