(author), Zečević, Jovana (author), De Jong, Krijn P. (author)In this study, Pt nanoparticles on zeolite/γ-Al2O3 composites (50/50 wt) were located either in the zeolite or on the γ-Al2O3 binder, hereby varying the average distance (intimacy) between zeolite acid sites and metal sites from "closest"to "nanoscale". The catalytic performance of these catalysts was compared to physical mixtures of zeolite...journal article 2020

(author), Zečević, Jovana (author), De Jong, Krijn P. (author)Using model catalysts with well-defined particle sizes and morphologies to elucidate questions regarding catalytic activity and stability has gained more interest, particularly utilizing colloidally prepared metal(oxide) particles. Here, colloidally synthesized iron oxide nanoparticles (FexOy-NPs, size ∼7 nm) on either a titania (FexOy/TiO2)...journal article 2020

Sun, X. (author), Olivos Suarez, A.I. (author), Meijerink, Mark (author), Van Deelen, Tom (author), Ould-Chikh, Samy (author), Zečević, Jovana (author), de Jong, K.M. (author), Kapteijn, F. (author), Gascon, Jorge (author)The development of synthetic protocols for the preparation of highly loaded metal nanoparticle-supported catalysts has received a great deal of attention over the last few decades. Independently controlling metal loading, nanoparticle size, distribution, and accessibility has proven challenging because of the clear interdependence between...journal article 2017
