Third International Congress on Catalysis THE ROLE OF THE PLATINUM METALS IN HETEROGENEOUS CATALYTIC REACTIONS

The Third International Congress on Catalysis, organised most eficiently by the Royal Dutch Chemical Society, took place in Amsterdam from July 20 to 25. It was attended by 828 active members from 31 countries including 141 from the USA, 29 from the USSR, and 115 from Great Britain. Of the ninety-eight papers presented, twenty-seven refer to the use of the platinum group metals as catalysts, an...

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...

VII.C.6 Cathode Electrocatalysis: Platinum Stability and Non-Platinum Electrocatalysts

Objectives • Elucidate rates and mechanisms of the degradation of polymer electrolyte fuel cell (PEFC) platinum electrode performance – Effect of electrolyte, potential (holding and cycling), time, and temperature • Develop non-platinum cathode electrocatalysts for PEFCs – Transition metal carbides and nitrides – Bi-metallic systems – Metal centers attached to electron-conducting polymer backbones

WHAT promises to be the most complete and authoritative work on platinum and platinum deposits is about to be published in Geneva, Switzerland. The author, Louis Duparc, is professor of chemistry and petrology in the University of Geneva; the name of Marguerite N. Tikonovitch is announced as that of the associate author.' Professor Duparc has long been known as the writer of many papers on the ...
