Catalysis
Catalysis is the change in rate of a chemical reaction due to the participation of a substance called a catalyst. Unlike other reagents that participate in the chemical reaction, a catalyst is not consumed by the reaction itself. A catalyst may participate in multiple chemical transformations....

Early history

Somorjai was born in Budapest
Budapest
Budapest is the capital of Hungary. As the largest city of Hungary, it is the country's principal political, cultural, commercial, industrial, and transportation centre. In 2011, Budapest had 1,733,685 inhabitants, down from its 1989 peak of 2,113,645 due to suburbanization. The Budapest Commuter...

 in 1944 who issued Swedish passports to Somorjai's mother, himself and his sister saving them from the Nazi death camps. While Somorjai's father ended up in the camp system, he was fortunate to survive but many of Somorjai's extended family ended up in the camp system.

He was studying chemical engineering at the Budapest University of Technology and Economics

Chemical research

The introduction of new technology such as low-energy electron diffraction revolutionised the study of surfaces in the 1950s and 1960s. However, early studies were limited to surfaces such as silicon, important for its electrical properties. In contrast, Somorjai was interested in surfaces such as platinum
Platinum
Platinum is a chemical element with the chemical symbol Pt and an atomic number of 78. Its name is derived from the Spanish term platina del Pinto, which is literally translated into "little silver of the Pinto River." It is a dense, malleable, ductile, precious, gray-white transition metal...

 known for its chemical properties.

Somorjai discovered that the defects on surfaces is where catalytic reactions take place. When these defects break, new bonds are formed between atoms leading to complex organic compounds such as naphtha
Naphtha
Naphtha normally refers to a number of different flammable liquid mixtures of hydrocarbons, i.e., a component of natural gas condensate or a distillation product from petroleum, coal tar or peat boiling in a certain range and containing certain hydrocarbons. It is a broad term covering among the...

 where he gave advice on how to make ice-skating surfaces as fast as possible. Somorjai's research had shed new light on ice, demonstrating that skaters skated on vibrating molecules rather than water on top of the ice acting as a lubricant.

During his career, Somorjai has published more than one thousand papers and three textbooks on surface chemistry and heterogeneous catalysis. He is now the most-often cited person in the fields of surface chemistry and catalysis.

, for his "extraordinarily creative and original contributions to surface science and catalysis". He was awarded the prestigious BBVA Frontiers of Knowledge Award in Basic Science in 2010. No one understands why the Nobel Prize committee passed him over, awarding the prize for surface-chemistry to Gerhard Ertl alone in 2007. Ertl himself has expressed surprise about this.
