Platinum as catalyst

Döbereiner discovered that hydrogen gas ignites in the presence of powdered platinum without the platinum being consumed, which laid the groundwork for the idea of metal catalysis in chemical reactions. This led to the innovation of an automatic lighter and has significant implications for industrial chemistry.
