Surface Basicity of Metal@TiO to Enhance Photocatalytic Efficiency for CO Reduction.

Photocatalytic reduction of CO to valuable chemical fuels is of broad interest, given its potential to activate stable greenhouse CO using renewable energy input. We report how to choose the right metal cocatalysts in combination with the surface basicity of TiO to enhance their photocatalytic efficiency for CO photoreduction. Uniform ligand-free metal nanoparticles (NPs) of Ag, Cu, Au, Pd, and Pt, supported on TiO, are active for CO photoreduction using water as an electron donor.

Structural Engineering in the Self-Assembly of Amphiphilic Block Copolymers with Reactive Additives: Micelles, Vesicles, and Beyond.

Control of polymer assemblies in solution is of great importance to determine the properties and applications of these polymer nanostructures. We report a novel co-self-assembly strategy to control the self-assembly outcomes of a micelle-forming amphiphilic block copolymer (BCP) of poly(ethylene oxide) (PEO) and poly[3-(trimethoxysilyl)propyl methacrylate] (PTMSPMA), PEO--PTMSPMA. With a reactive and hydrophobic additive tetraethyl orthosilicate (TEOS), the assembly nanostructures of PEO--PTMSPMA are tunable.
