Applied Homogeneous Catalysis

Arno Behr was born in 1952 in Aachen, Germany. He received his Diploma in chemistry from RWTH Aachen University and fi nished his PhD in 1979 under supervision of Prof. Willi Keim. After being employed at Henkel KGaA he is a full Professor of Technical Chemistry at DortmundUniversity, Germany since 1996. Since 35 years his research interests cover homogeneous transition-metal catalysis, conversion of petrochemicals and renewables and catalyst recycling. During the last 30 years he became an experienced lecturer, held GDCh- and Dechema lectures and was involved in several advanced master and PhD courses. Peter Neubert was born in 1981 in Castrop-Rauxel, Germany. He studied chemistry at Technische Universitat Dortmund, Germany and Bergen University, Norway. He received his diploma in 2009 under the supervision of Professor Arno Behr. He is currently a doctoral candidate in the same group. His current research deals with the catalytic conversion of C5 materials and the development of recycling concepts in homogeneous catalysis.
