This diagram might help explain better the basic composition and function of a catalytic converter: These are the different types of catalytic converters. 1. Petrol-based catalytic converters Three-way Catalytic Converter It is called three-way because of three reactions happening in...
PGMs function as catalysts in important processes, including ammonia and ammonium nitrate production [[15], [16], [17], [18]], catalytic converters [1,12,19,20], hydrogen fuel cells [[21], [22], [23], [24], [25]] and various other areas of significance. PGM catalysts constitute ...
in catalytic converters in automobiles, where they convert noxious gases from exhaust fumes (such as carbon monoxide, unburnt hydrocarbons and oxides of nitrogen) to carbon dioxide and water. Additional PGE demand occurs for jewelry plus minor uses in many other industry sectors (petroleum, ...

predicted that we may have already reached "peak platinum" production, though this seems to be predicated on the belief that production of hybrid and electric vehicles will remove the demand for both fuel cells and catalytic converters in future years, rather than a firm belief in supply ...

Among the precious metals, Pd recovery in the form of biomass-associated nanopalladium has received most attention during the previous decades (Table 1). Pd is widely used in catalytic converters, electronic items, dentistry, jewelry, medicine, hydrogen purification, organic synthesis, gas sensors, ...

In industrial catalysis, platinum-based (Pt-based) materials are crucial for automotive catalytic converters, where they can accelerate the breakdown of noxious gases into less harmful substances, thereby reducing vehicle emissions [10]. In biomedicine, PtNPs are explored for their potential in ...
