The chemistry of platinum group metals is a rapidly expanding commercially important field. It is dominated by the catalytic properties of the metals. They are useful in petrochemical and general chemical plants and are becoming increasingly important as autocatalysts for pollution control. The book covers recent developments in the chemistry of the six platinum group metals, namely, platinum, palladium, rhodium, iridium, ruthenium and osmium. The material falls into three broad areas. Firstly, the occurrence, extraction and use of the metals, especially in catalysis, electrochemistry, energy

This edited volume presents new data and insights from the most internationally respected PGE experts, representing a variety of disciplines ranging from chemistry, geochemistry, biology, environmental science to toxicology and environmental health. It builds upon three previous co-edited books published by Springer, Zereini and Alt (Eds.) (1999, 2000 and 2006), incorporating the most recent advances on the topic. The book covers the following topical areas related to PGE: sources and applications, analytical methods, environmental fate, bioavailability and chemical behaviour, use of bioindicators and human exposures and health risk potential. Highly interdisciplinary in orientation, this book is a comprehensive guide to academics, students and professionals working in a number of different scientific fields, who are interested in topics related to platinum metal emissions in the environment. .

Platinum group metals (PGMs) are among the 27 raw materials labeled as critical by the EU in 2017 due to their economic importance and supply risk. South Africa and Russia collectively produce approximately 80% of the global PGM mine production. The single biggest application of Pt, Pd, and Rh is in automotive catalytic converters (ACCs) to abate the emissions from engine exhaust. Each ACC contains a few grams of these precious metals. The concentration of PGMs in ACC urban mines (>2000 ppm) is much higher than that of conventional mines (<10 ppm). Thus, recycling of end of life automotive catalytic converters (ACCs) present an important source of platinum group metals (PGMs). The circular economy of ACC not only helps Europe further develop domestic production but has several economic and ecological benefits. PGMs are currently recycled from ACCs by pyrometallurgical means and the development of low-cost alternatives in hydrometallurgy has long been the focus of research. The efficiency of the economical leaching techniques has generally been low, owing to the paucity of understanding of a very complex and heterogeneous ACC material and insufficient process-oriented characterization. An in-depth literature study suggested that automotive catalysis is a broad field and ACC input material is influenced by several factors including technological and legislative development, size and type of engine, manufacturer, etc. It was also found that due to the nano nature of PGMs in ACCs, the potential of SEM characterization has been under-utilized. SEM characterization showed structural and compositional differences between ceramic three-way catalysts (CTWC), metallic three-way catalysts (MTWC), diesel oxidation catalysts (DOC), and diesel particle filter (DPF). It was also found that harsh operating conditions further impact the ACC material as analyzed under SEM. PGM particles were not only visualized but key processes that happen over time such as catalyst poisoning, PGM, and washcoat component thermal sintering, were obvious which influence chemical composition and particle size/porosity reduction. All this information was found to be of great relevance for subsequent leaching processes. Leach feed and residue samples also showed that some information on the process controls could be acquired using SEM. It was also found that the statistics from the automotive market and basic understanding of ACCs could help in defining different sections of ACC-urban mines based on grade and PGM type.
