The major applications of PGMs are as catalysts in automotive industry, petroleum refining, environmental (gas remediation), industrial chemical production (e.g., ammonia production, fine chemicals), electronics, and The global demand for platinum-group metals (PGMs), including Pt, Pd, and Rh, far exceeds the supply of natural resources. The scarce and inhomogeneous distribution of the resources, high production costs, and serious environmental risks stimulate the recycling of PGMs from spent automotive catalysts (SAC). From this point, Platinum-group metals: Demand, supply, applications and

What Are the Platinum Group Metals and Why Do They

Platinum (Pt): Platinum is probably the most recognized of the PGMs because of its use in jewelry, but its main application is the manufacture of catalytic converters as well as other industrial applications. Platinum has a high melting point and temperature stability, is highly corrosion oxidation resistant, and it is a good oxidation This manuscript reviews the current trends in the recovery of Platinum Group Metals (PGMs) from end-of-life autocatalysts and the aims of the recently funded Marie Sklodowska-Curie Project “Chemistry of Platinum Group Metals-CHemPGM” towards the greening of PGMs recovery processes and the reusing of recovered PGMs for Platinum Group Metals: Green Recovery from Spent Auto

Solvometallurgical Recovery of Platinum Group Metals from

The platinum group metals (PGMs) platinum, palladium, and rhodium are primarily used in clean technologies and high-tech equipment. An important application of these PGMs is automotive catalytic converters, which substantially reduce the exhaust pollutant emissions of CO, NO x, and hydrocarbons from the internal combustion engines by converting Nevertheless, large-scale production and commercialization of PEMFCs is impeded by the high cost of platinum [1]. First-row transition metals (TMs) supported on nitrogen-doped porous carbon (referred to as TM−N−C materials) are one of the most promising platinum group metal-free (PGM-free) catalysts to replace precious metals in Platinum group metal-free Fe−N−C catalysts for PEM fuel

A Study of Platinum Group Metals in Three-Way

Introduction. Since their introduction in 1974 three-way catalysts (TWCs) have used platinum group metals (pgms) to control emissions of hydrocarbons (HCs), carbon monoxide (CO) and oxides of nitrogen (NOx) in gasoline powered cars ().A mixture of some or all of Pt, Pd and Rh have always been used, with Rh being especially active for NOx conversion and The platinum group metals (PGMs) comprise 6 elements, which are platinum, palladium, rhodium, ruthenium, iridium, and osmium. These metals have high melting points, high heat resistance, high corrosion resistances, and unique catalytic properties. Owing to these properties, PGMs are being used widely in many industrial fields, most notably as Platinum Group Metal an overview ScienceDirect Topics

Recycling of platinum-group metals from spent

There is a severe conflict between supply and demand of platinum-group metals (PGMs). Spent automotive catalysts (SAC) are one of the most promising resources for recovering PGMs. Smelting is dominant in recovering PGMs from SAC. The PGMs collection efficiency can be enhanced by controlling the whole smelting process.Platinum group metals (PGM) Package type catalytic oxidation units that contain manganese dioxide-copper oxide catalyst are used commercially to destroy ethylene oxide emitted by sterilization systems.
