‘What is a palladium catalyst, after all?’ Are they around us?’<\/p>\n\n\n\n

We have written this article to answer these questions.<\/p>\n\n\n\n

In this article, we will give a biting explanation of palladium catalysts, followed by a simple explanation with familiar examples.<\/p>\n\n\n\n

We hope that by the end of reading the article, you will have an idea of palladium catalyst.<\/p>\n\n\n\n

Let\u2019s have a look.<\/p>\n\n\n\n

<\/div>\n\n\n\n

What is a palladium catalyst?<\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Palladium catalysts are manufactured using palladium-containing compounds as catalysts.<\/p>\n\n\n\n

They are used as catalysts for hydrogenation and oxidation and are indispensable in organic synthesis.<\/p>\n\n\n\n

Among other things, this method is used for ‘cross-coupling synthesis’ and is used for basic research and as an industrial manufacturing method.<\/p>\n\n\n\n

<\/div>\n\n\n\n

Cross-coupling synthesis is the joining of two molecules into a single molecule.<\/h3>\n\n\n\n

Cross-coupling synthesis is a chemical reaction in which two molecules with different structures are combined to form a single molecule.<\/p>\n\n\n\n

The ‘Heck reaction’, ‘Negishi coupling reaction’ and ‘Suzuki coupling reaction’ are used for palladium catalysis.<\/p>\n\n\n\n

<\/div>\n\n\n\n

How Palladium is used in society.<\/h2>\n\n\n\n

Palladium catalysts are used in society for ‘gas purification in petrol cars’, ‘filters in IH grills (Panasonic)’ and ‘pharmaceuticals’.<\/p>\n\n\n\n

Let\u2019s look at each of them.<\/p>\n\n\n\n

<\/div>\n\n\n\n

Gas purification for petrol vehicles.<\/h3>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Palladium has long been used in petrol-fuelled autocatalysts.<\/p>\n\n\n\n

Specifically, it is included with rhodium and platinum in catalytic converters that purify toxic gases, making them non-toxic through a catalytic reaction.<\/p>\n\n\n\n

    \n
  • HC (hydrocarbons) \u2192 oxidation \u2192 H2O + CO2 (water and carbon dioxide)<\/li>\n\n\n\n
  • CO (carbon monoxide) \u2192 oxidation \u2192 CO2 (carbon dioxide)<\/li>\n\n\n\n
  • NOx (nitrogen oxides) \u2192 reduction \u2192 N2 + O2 (nitrogen, oxygen)<\/li>\n<\/ul>\n\n\n\n
    <\/div>\n\n\n\n

    Filters for IH grills (Panasonic)<\/h3>\n\n\n\n
    \"\"<\/figure>\n\n\n\n

    Panasonic’s IH grills, which are used for cooking, also incorporate a palladium catalyst.<\/p>\n\n\n\n

    Used as a filter for ‘smoke and odor removal’, the palladium catalyst combined with a platinum catalyst breaks down hydrocarbons, the main component of smoke, into water and carbon dioxide.<\/p>\n\n\n\n

    What it does is almost the same as gas purification in petrol-powered vehicles.<\/p>\n\n\n\n

    <\/div>\n\n\n\n

    Medicines (e.g. blood pressure drugs, anti-cancer drugs)<\/h3>\n\n\n\n
    \"\"<\/figure>\n\n\n\n

    Palladium-catalyzed cross-coupling synthesis is also used in pharmaceuticals.<\/p>\n\n\n\n

    For example, the blood-pressure-lowering drug losartan, the anticancer drug imatinib, etc.<\/p>\n\n\n\n

    The elucidation of molecules and catalytic performance is also useful in these medical fields.<\/p>\n\n\n\n

    \"\"<\/figure>\n\n\n\n

    Palladium catalysts are used in petrol vehicles.<\/p>\n\n\n\n

    Platinum catalysts were originally used in many diesel vehicles and, in comparison, platinum catalysts offer better performance.<\/p>\n\n\n\n

    So why was the palladium catalyst chosen? The amount of money behind it was.<\/p>\n\n\n\n

    Palladium was used because it was cheaper than platinum at the time, and its performance was sufficient for petrol-powered vehicles.<\/p>\n\n\n\n

    However, the price of palladium, which was cheap at the time, rose sharply due to increased demand for petrol-powered vehicles.<\/p>\n\n\n\n

    As of 2023, it has become more expensive than platinum and gold.<\/p>\n\n\n\n

    As a result, many petrol vehicles now contain platinum catalysts, and catalytic converters containing rhodium, platinum and palladium are often used.<\/p>\n\n\n\n

    <\/div>\n\n\n\n

    Summary<\/h2>\n\n\n\n

    In this article, we explained the palladium catalyst.<\/p>\n\n\n\n

    Let’s look back at the key points.<\/p>\n\n\n\n

    The key points of this article are following.<\/p>\n\n\n\n

      \n
    • Palladium catalysts are used for hydrogenation, oxidation and other catalytic applications, particularly in organic synthesis<\/li>\n\n\n\n
    • In society, it is used for ‘gas purification in petrol-powered vehicles’, ‘filters for IH grills’, ‘pharmaceuticals’, etc.<\/li>\n\n\n\n
    • Prices are currently rising.<\/li>\n<\/ul>\n\n\n\n
