Platinamu boka simbi dzinosanganisira platinamu (Pt), rhodium (Rh), palladium (Pd), ruthenium (Ru), osmium (Os), uye iridium (Ir), izvo zviri zvesimbi dzinokosha segoridhe (Au) uye sirivheri (Ag) . Vane ma bond akasimba kwazvo emaatomu, uye nekudaro vane simba guru rekubatanidza maatomu uye huwandu hwehuwandu hwehuwandu. Atomic coordination nhamba yeese platinamu boka simbi i6, iyo inosarudza iwo akasiyana emuviri nemakemikari zvimiro. Masimbi eplatinamu ane mapoinzi ekunyungudika, yakanaka conductivity yemagetsi uye corrosion resistance, kusimba kwetembiricha yepamusoro uye tembiricha yekukwira inokwira, uye kugadzikana kwakanaka kwekushisa. Aya maitiro anovaita zvinhu zvakakosha zveindasitiri yemazuva ano uye kuvaka kwedziviriro yenyika, inoshandiswa zvakanyanya mundege, aerospace, maroketi, atomic simba, microelectronics tekinoroji, kemikari, girazi, kucheneswa kwegasi uye maindasitiri esimbi, uye basa ravo mumaindasitiri epamusoro-soro riri kuwedzera. Naizvozvo, inozivikanwa se "vitamini" uye "yemazuva ano simbi itsva" yeindasitiri yemazuva ano.

Mumakore achangopfuura, masimbi eboka replatinamu ave achiwedzera kushandiswa mumaindasitiri akadai semotokari uye mudhudhudhu exhaust kucheneswa, masero emafuta, maindasitiri emagetsi nemagetsi, zvinhu zvemazino uye zvishongo. Muzana ramakore rechi21 rakaomarara, kugadzirwa kweplatinamu boka resimbi zvinhu zvinoganhurira zvakananga kukurumidza kukurumidza kweaya epamusoro-tech minda, uye zvakare kunokanganisa zvakananga chinzvimbo chepasirese muhupfumi hwenyika.

Semuyenzaniso, tsvakiridzo pamaitiro e electrocatalytic oxidation yemamorekuru madiki akadai semethanol, formaldehyde, uye formic acid, inogona kushandiswa semafuta maseru nenano platinum catalysts ine zvese kukosha kwekutanga theoretical research uye yakafara tarisiro yekushandisa. Zvidzidzo zvakaratidza kuti zvinokonzeresa zvine imwe electrocatalytic oxidation chiitiko chediki organic mamorekuru kazhinji platinamu boka simbi dzakanaka.

Hongwu Nano inyanzvi mukugadzira nano yakakosha simbi zvinhu pamakore gumi nemashanu, kusanganisira asi isina kuganhurirwa nano platinamu, iridium, ruthenium, rhodium, sirivheri, palladium, goridhe. Inowanzo kupihwa muupfu fomu, kupararira kunogonawo kugadziridzwa, uye saizi yechikamu inogona kugadziridzwa zvinoenderana nezvinodiwa chaizvo.
