54 OKK provided profound insight into the most recent breakthroughs and innovative headway in the field of catalysis. This three-day event consisted of the keynote, oral, flash oral, and poster sessions. The topics of the 54 OKK covered a wide-ranging discussion on catalysis for application in oxidative dehydrogenation, photocatalytic selective oxidation, and biology. There were also interesting discussions related to computational studies on catalysts. Scientific contributions dealing with heterogeneous and homogeneous catalysis from fundamental research to applied catalytic processes included researchers from the academic and industrial world.
