This volume contains invited papers and communications presented at the Second World Congress and Fourth European Workshop Meeting on New Developments in Selective Oxidation. The purpose of the meeting was to present new topics and recent advances as well as the discussion of new aspects of fundamental and applied aspects of partial selective oxidation in heterogeneous and homogeneous catalysis. The following topics were discussed: new processes for fine chemicals by catalytic oxidation; recent developments in surface chemistry of oxide catalysts; novel catalytic systems and preparation methods; heterogenized homogeneous oxidation catalysts; Selective oxidation and oxidative dehydrogenation of alkanes; new industrial developments based on catalytic oxidation reactions; bio-, photo-, and electro-catalytic oxidation; oxidation by other agents than dioxygen; bifunctional metal-on-metal oxide catalysts for selective oxidation. This book should provide a valuable set of data on selective oxidation reactions which should be useful to catalyst and related practitioners, whether fundamentalists or highly applied, and to process engineers who wish to evaluate current findings in this field.
