Platinum pab pawg hlau muaj xws li platinum (Pt), rhodium (Rh), palladium (Pd), ruthenium (Ru), osmium (Os), thiab iridium (Ir), uas yog cov hlau zoo li kub (Au) thiab nyiaj (Ag) . Lawv muaj cov atomic bonds muaj zog heev, thiab yog li muaj kev sib raug zoo sib raug zoo nrog lub zog thiab qhov siab tshaj plaws. Lub atomic coordination tooj ntawm tag nrho cov platinum pab pawg neeg hlau yog 6, uas txiav txim siab lawv cov cim lub cev thiab tshuaj. Platinum pab pawg hlau muaj cov ntsiab lus siab melting, zoo hluav taws xob conductivity thiab corrosion kuj, siab kub zog thiab kub creep kuj, thiab zoo kub stability. Cov yam ntxwv no ua rau lawv cov ntaub ntawv tseem ceeb rau kev lag luam niaj hnub thiab kev tsim kho hauv tebchaws, dav siv hauv aviation, aerospace, foob pob hluav taws, atomic zog, microelectronics technology, tshuaj, iav, roj purification thiab metallurgical industries, thiab lawv lub luag hauj lwm nyob rau hauv high-tech industries yog nce. Yog li ntawd, nws yog hu ua "vitamin" thiab "niaj hnub tshiab hlau" ntawm kev lag luam niaj hnub.

Nyob rau hauv xyoo tas los no, platinum pab pawg hlau tau siv ntau dua hauv kev lag luam xws li tsheb thiab maus taus purification, roj hlwb, hluav taws xob thiab hluav taws xob kev lag luam, cov ntaub ntawv kho hniav thiab cov hniav nyiaj hniav kub. Nyob rau hauv lub xyoo pua 21st, txoj kev loj hlob ntawm platinum pab pawg hlau cov ntaub ntawv ncaj qha txwv txoj kev loj hlob ceev ntawm cov high-tech teb no, thiab kuj ncaj qha cuam tshuam rau ib tug thoob ntiaj teb txoj hauj lwm nyob rau hauv lub ntiaj teb no kev khwv nyiaj txiag.

Piv txwv li, kev tshawb fawb ntawm electrocatalytic oxidation tus cwj pwm ntawm cov organic molecules me me xws li methanol, formaldehyde, thiab formic acid, uas tuaj yeem siv los ua cov roj hlwb los ntawm nano platinum catalysts muaj ob qho tseem ceeb ntawm cov kev tshawb fawb theoretical thiab kev siv dav dav. Cov kev tshawb fawb tau pom tias cov catalysts tseem ceeb nrog qee yam electrocatalytic oxidation kev ua rau me me cov organic molecules feem ntau yog platinum pab pawg neeg noble hlau.

Hongwu Nano yog tshwj xeeb hauv kev tsim cov khoom siv nano precious hlau tshaj 15 xyoo, suav nrog tab sis tsis txwv rau nano platinum, iridium, ruthenium, rhodium, nyiaj, palladium, kub. Nws feem ntau yog muab rau hauv daim ntawv hmoov, qhov dispersion kuj tuaj yeem hloov kho, thiab qhov loj me tuaj yeem hloov kho raws li cov kev xav tau tshwj xeeb.
