Explain industrial role of platinum?
Accepted Answer
Platinum is a crucial catalyst in various industrial processes, particularly in organic chemistry. It plays a key role in:
Petroleum Refining: Platinum-based catalysts are used in catalytic reforming, a process that converts straight-chain alkanes into branched alkanes and aromatic hydrocarbons, improving gasoline octane rating.
Automotive Emissions Control: Platinum catalysts are used in catalytic converters to oxidize harmful pollutants like carbon monoxide and hydrocarbons into less harmful carbon dioxide and water.
Chemical Synthesis: Platinum catalysts are employed in various organic reactions like hydrogenation (adding hydrogen to a molecule) and oxidation, contributing to the synthesis of pharmaceuticals, plastics, and other chemicals.
