Description
Surface modification of (semi)conducting materials with polymers provides a strategy for interfacing electrodes with electrocatalysts for reactions of industrial importance. The resulting constructs create opportunities to capture, convert and store solar energy in the form of chemical bonds, generating solar fuels. This thesis describes III-V semiconductors, modified with molecular catalysts embedded in thin-film polymeric coatings. Overarching goals of this work include building protein-like, soft-material environments on solid-state electrode surfaces. This approach enables coordination of earth-abundant metal centers within the three-dimensional molecular coatings to modulate the electronic and catalytic properties of the overall assembly and provide assemblies for studying the effects of polymeric-encapsulation on electrocatalytic as well as photoelectrosynthetic performance. In summary, this work provides 1) new approaches to designing, interfacing, and characterizing (semi)conducting and catalytic materials to effectively power chemical transformations (including hydrogen evolution and carbon dioxide reduction), and 2) kinetic models for better understanding the structure-function relationships governing the performance of these assemblies.
