Platinum Extraction Modeling from Used Catalyst by Iodine Solutions

Platinum extraction from spent reforming catalysts in iodine solutions under atmospheric pressure at different temperatures, acid concentration, and iodine spices concentration, catalyst particle size, and impeller agitation speed have been studied in our group. In this system, platinum is oxidized from spent catalyst with I3¯ that is formed ...

Urinary excretion of platinum from platinum industry workers.

OBJECTIVES Assessment of level of exposure to platinum and platinum concentration in urine from platinum industry workers to evaluate internal exposures and excretion kinetics. METHODS Platinum concentrations in urine samples from 34 workers were measured by adsorptive voltammetry after UV-photolysis. Morning and evening samples were taken two to six times during six months. Individual exposu...

Deposition of Platinum from Bis(Acetylacetonato)Platinum(II)

The evaporation and deposition process of Bis(acetylacetonato)platinurn(LI) fPt(acac)J was examined in a computerized microbalance system, which allows the measuring of the mass of evaporating precursor and depositing layer simultaneously. The investigations were carried out in an argon-atmosphere and an argonloxygen-atmosphere with pressure ranging from 250 Pa to 1000 Pa. The deposition kineti...

Tuning selectivity of electrochemical reactions by atomically dispersed platinum catalyst.

Maximum atom efficiency as well as distinct chemoselectivity is expected for electrocatalysis on atomically dispersed (or single site) metal centres, but its realization remains challenging so far, because carbon, as the most widely used electrocatalyst support, cannot effectively stabilize them. Here we report that a sulfur-doped zeolite-templated carbon, simultaneously exhibiting large sulfur...

Reaction of Hydrogen with Oxygen Adsorbed on a Platinum Catalyst.

The release of hydrogen atoms by a platinum surface in contact with molecular hydrogen occurs if there is oxygen in the system. In particular, it is sufficient that the oxygen be adsorbed at the surface of the metal.
