Tannic Acid Assisted Construction of Au-Ti Integrated Catalyst Regulating the Local Environment of Framework Ti toward Propylene Epoxidation under H2/O2

Review and perspectives on TS-1 catalyzed propylene epoxidation

“…using XANES spectroscopy. 334 An-Au@TS-1 exhibits higher LIII edge intensity, indicating the loss of more d-electrons ( Figure 18 B). The An-Au@TS-1 composite catalyst can better interact with the titanium surface because of the presence of bridging oxygen.…”

Tannic acid adjusts Pd dispersity over Al2O3 for acetylene selective hydrogenation

“…Thus, TA shows strong surface adhesion to versatile substrates. Moreover, TA can self-polymerize into a porous scaffold that can trap and coordinate metal ions via the phenolic groups; 14 however, related works using TA as dispersants or stabilizers for Pd/Al 2 O 3 have not been reported.…”
