It was the first edition of a congress aiming at bringing together scientists, researchers, industrial engineers, and university students from different parts of the world, to give them the opportunity to present their research achievements in the field of applied catalysis, share and refine ideas, and develop new collaborations. CatET-2019 consisted of 33 presentations (4 keynotes, 24 oral communications, and 5 posters), which were split into 5 plenary sessions. Participants were from 14 countries: Bulgaria, China, France, Germany, India, Israel, Italy, Korea, Morocco, Russia, Saudi Arabia, Spain, Switzerland, and the USA. This Special Issue of Topics in Catalysis contains a selection of contributions from the participants in CatET-2019. The selected articles [1] [2] [3] [4] [5] [6] [7] [8] [9] , which went through a rigorous peer-review process, represent the most interesting topics addressed at the congress. Gold catalysts are the protagonists of articles [1] [2] [3] . Gold nanoparticles supported on C and N co-decorated alumina [1] and on Ce-Zr oxides [2] were investigated for selective hydrogenation of acetylene, and polyaniline microtubes have been proposed as a support for gold nanoparticles to improve the catalytic performance in reduction of nitrophenols [3] . Optimization of supports in bifunctional supported Pt catalysts for hydrocracking of polystyrene to liquid fuels is the subject of the work by González-Marcos et al. [4] . The focus of articles [5] [6] [7] is on catalytic combustion. Singh et al. [5] investigated transition metal (Ni, Cu or Fe)substituted Co 3 O 4 -ZrO 2 catalysts for lean methane combustion. In article [6] , synergy between ceria and metals (Ag or Cu) was explored for soot combustion during regeneration of catalytic diesel particulate filters (DPFs). Landi et al. [7] carried out a numerical investigation of the combined effects of initial temperature and catalyst activity on the dynamics of soot combustion in catalytic DPFs. Their results pave the way for the passage to a continuous functioning mode for such devices, with regeneration taking place simultaneously, and not alternately, to filtration at the conditions of the exhaust gases fed to the filter. Kanhounnon et al. [8] demonstrated, through density functional theory calculations, the importance of the presence of a catalyst to an efficient purification of fuels via elimination of thiophenic compounds by cycloaddition with ethylene. The work by Jayanthi et al. [9] provides new insights into the photocatalytic performance of TiO 2 prepared by thermal processing of organic-inorganic hybrid thin films deposited by molecular layer deposition, highlighting the key role played by strain effects in affecting the electronic structure of the catalyst. We are indebted to Prof. Hans-Joachim Freund, Editor-in-Chief of Topics in Catalysis, for inviting us to lead this Special Issue as Guest Editors. We also express our gratitude to Mr. Robert Rae, Head of Operations at Research Fringe, for suggesting our names to Prof. Freund, and to Mr. Matthew Smyllie and Mr. Gursimaran Kaur, from the Springer Nature editorial team, for their valuable assistance in the preparation of this Special Issue. Finally, we wish to thank the authors for submitting their high-quality manuscripts, and the reviewers for their time and effort, and helpful criticism. Due to the Covid-19 pandemic, the second edition of the Word Summit "Catalysis Engineering & Technology", initially scheduled for October 5-6, 2020 in Brussels (Belgium), has been postponed. The new dates are expected to be announced soon. 2020) C, N co-decorated alumina-supported Au nanoparticles: Enhanced catalytic performance for selective hydrogenation of acetylene Gold nanoparticles supported on Ce-Zr oxides for selective hydrogenation of acetylene Preparation of polyaniline microtubes as the gold catalyst support with improved catalytic performances for the reduction of nitrophenols Optimization of supports in bifunctional supported Pt catalysts for polystyrene hydrocracking to liquid fuels Transition metal (Ni, Cu and Fe) substituted Co 3 O 4 -ZrO 2 catalysts for lean methane combustion Synergy between ceria and metals (Ag or Cu) in catalytic diesel particulate filters: effect of the metal content and of the preparation method on the regeneration performance A numerical investigation of the combined effects of initial temperature and catalyst activity on the dynamics of soot combustion in a catalytic diesel particulate filter Elimination of thiophenic compounds by cycloaddition with ethylene for an efficient purification of fuels: a DFT study Photoreactivity of deep VB titania attained via molecular layer deposition; interplay of metal oxide thin film built-in strain and molecular effects
