Gerhard Ertl A contribution towards chemistry Gerhard Ertl was born on October 10, 1936, in Bad Cannstadt, Germany. Ertl is considered to be one of the few scientist to focus on a new strand of semiconductors. Along with that he also managed to develop the methodology for modern surface chemistry(Chemical Processes on Solid Surfaces, 2007). The method used is to observe the atoms, and molecules on surface metal which is uncontaminated. The method that does this uses high vacuums(Chemical Processes on Solid Surfaces, 2007). He also revised the Haber-Bosch process, ammonia which is used for artificial fertilizer is created from nitrogen and hydrogen on an iron surface(Chemical Processes on Solid Surfaces, 2007). Oxidation was another one of his studies, he looked at the oxidation of carbon monoxide on platinum, and alongside that the catalytic oxidation of carbon monoxide over palladium. He also determined the chemical reactions of tiny ice crystals in the stratosphere cause damage to the Earth’s protective ozone layer, and his work has advanced the scientific understand of why certain things happen(Chemical Processes on Solid Surfaces, 2007). Examples can include why iron rusts, which is a big question for people, why does it? Ertl also described himself in his former biographies that he was very good at math, and also decided to study physics instead of chemistry, so he attended the Technical University of Stuttgart int he year of 1995(History1900s.about.com, 2014). A diploma was attained shortly after in 1961, where he then spent times between Universities in Munich and Paris(History1900s.about.com, 2014). In his biography he goes on to saying that his first real research assignment was to develop such an apparatus and measure... ... middle of paper ... .... With the help of low-energy electron diffraction, and measurements of desorption with models, Ertl was able to provide a description of how hydrogen is exposed on metal surfaces.
