Show Abstract
Human-engineered materials capable of generating fuels from sustainable energy sources provide an approach to satiating modern societies' energy demands, with minimal environmental impact.1 In this poster presentation, I will describe hybrid photoelectrosynthetic assemblies composed of gallium phosphide (GaP) functionalized with metalloporphyrin complexes of five different transition metal ions: Fe(III), Co(II), Ni(II), Cu(II), and Zn(II). Surface attachment of these metalloporphyrin complexes was achieved using a previously reported UV-induced photochemical grafting method.2 The photoelectrochemical properties of these heterogeneous-homogeneous materials will be contrasted with electrochemical properties of the isolated, homogeneous metalloporphyrins and other previously reported heterogeneous-homogeneous constructs.3,4
