Moreover, in Adrian Miller’s words (Editor of Advanced Functional Materials) the latest front cover really goes above and beyond. I was blown away by this cover when we first received the suggestion, and it was the talk of the office for weeks. As far as I know, we’ve never published a painting as a front cover before.
The article Zeolite Catalysts with Tunable Hierarchy Factor by Pore-Growth Moderators (Adv. Funct. Mater. 2009, 19, 3972-3979), co-authored by Javier Pérez-Ramírez, Danny Verboekend, Adriana Bonilla and Sònia Abelló, has been highlighted on the front-cover of Advanced Functional Materials on its last issue of the year.The authors introduce the hierarchy factor as a valuable descriptor to categorize hierarchical zeolites and to optimize their design for catalytic applications and they also demonstrate a direct correlation between the catalytic performance of ZSM-5 in benzene alkylation and the hierarchy factor. Maximization of the hierarchy factor is achieved by enhancing the mesopore surface area without reducing the micropore volume. For this purpose, a novel desilication variant involving NaOH treatment in the presence of pore growth moderators (quaternary ammonium cations) is presented.
