A reasonable case could be made that the scientific interest in
catalytic oxidation was the basis for the recognition of the
phenomenon of catalysis. Davy, in his attempt in 1817 to understand
the science associated with the safety lamp he had invented a few
years earlier, undertook a series of studies that led him to make
the observation that a jet of gas, primarily methane, would cause a
platinum wire to continue to glow even though the flame was
extinguished and there was no visible flame. Dobereiner reported in
1823 the results of a similar investigation and observed that
spongy platina would cause the ignition of a stream of hydrogen in
air. Based on this observation Dobereiner invented the first
lighter. His lighter employed hydrogen (generated from zinc and
sulfuric acid) which passed over finely divided platinum and which
ignited the gas. Thousands of these lighters were used over a
number of years. Dobereiner refused to file a patent for his
lighter, commenting that "I love science more than money." Davy
thought the action of platinum was the result of heat while
Dobereiner believed the ~ffect ~as a manifestation of electricity.
Faraday became interested in the subject and published a paper on
it in 1834; he concluded that the cause for this reaction was
similar to other reactions.
