Novel organically linked Zn hydrogenselenite coordination polymers: synthesis, characterization, and efficient TiO photosensitization for enhanced photocatalytic hydrogen production.

This study focused on the solvothermal synthesis, characterization, and photocatalytic activities of two novel coordination polymers, namely [Zn(μ-HSeO)(bipy)] (1) and [Zn(μ-HSeO)(phen)] (2). These compounds represent the first organically linked Zn hydrogenselenite coordination polymers. The synthesis of compounds 1 and 2 involved the addition of 2,2'-bipyridine and 1,10-phenanthroline, respectively, to SeO and ZnO in methanol as the solvent.

Polymer-coated palladium nanoparticle catalysts for Suzuki coupling reactions.

A set of seven different palladium nanoparticle (PdNP) systems stabilized by small amounts (1.0mg/mL) of structurally related macromolecular capping agents were comparatively tested as catalyst in p-nitrophenol (Nip) reduction and Suzuki cross-coupling reactions. The observed rate constants (kobs) for Nip reduction were in the range of 0.
