New Insights into the Structure and Degradation of Alizarin Lake Pigments: Input of the Surface Study Approach

Guanzheng Zhuang, Silvia Pedetti, Yoan Bourlier, Philippe Jonnard, Christophe Méthivier, Philippe Walter, Claire-Marie Pradier, Maguy Jaber

Alizarin (Az) lake is a typical example of madder lake pigments that are widely used in cultural heritages. Previous work focused on the complex formation in solution, theoretical models, and crystallized stoichiometric structures (Az/Al3+ = 1:1 or 2:1). However, the classical recipe for preparing…

Chromium sites in zeolite framework: Chromyl or chromium hydroxyl groups?

Frederik Tielens, Mazharul M. Islam, Gabriella Skara, F. de Proft, Tetsuya Shishido, Stanislaw Dzwigaj

A combined experimental and ab initio periodic DFT calculation on the structure and stability of different chromium-substituted zeolite models are presented. Experimental investigation by XRD, FT-IR and UV-vis show the presence of chromium in SiBEA zeolite. The favorable chromium sites are…
