Cu-decorated Raschig-TiO2 rings inducing MB repetitive discoloration without release of Cu-ions under solar light

César Pulgarin, Juan Kiwi, Rosendo Sanjines, Helena Luisa Teixido Pedarros, Laura Victoria Suárez Murillo

The methylene blue (MB) discoloration on innovative photocatalysts made up of Raschig-rings coated by pre-formed TiO2 nanoparticles decorated with CuOx (RR@TiO2-Cu) is presented. The MB-discoloration was drastically accelerated by the subsequent addition o ...

Natural inspirations for metal–ligand cooperative catalysis

Xile Hu, Matthew Wodrich

In conventional homogeneous catalysis, supporting ligands act as spectators that do not interact directly with substrates. However, in metal–ligand cooperative catalysis, ligands are involved in facilitating reaction pathways that would be less favourable ...
