International Classification:

H05K 1/09
B82Y 99/00

US Classification:

174257, 977773, 977932

Abstract:

The present invention provides an electrode which comprises (a) a supporting substrate, and (b) nanoparticle composition comprising optically transparent conductive nanoparticles. In one embodiment, the nanoparticles are selected from tin-doped indium oxide (ITO), fluorine doped tin oxide (FTO), antimony tin oxide (ATO), gallium zinc oxide (GZO), indium zinc oxide (IZO), copper aluminum oxide, fluorine-doped zinc oxide and aluminum zinc oxide (AZO) nanoparticles and combinations thereof. In one embodiment, the electrode further comprises a transition metal catalyst, and the catalyst is absorbed to the surface of the nanoparticles. Another aspect of the invention relates to methods for preparing the electrode described herein which comprises the step of (1) preparing a suspension of nanoparticles; (2) applying the suspension of the nanoparticles to a support substrate; and (3) annealing the supporting substrate with the nanoparticle for a period of time and at a temperature sufficient to produce nanoparticle film on the electrode.

International Classification:

C25B 11/04
B01J 31/26
C25B 1/04

US Classification:

205630, 204294, 252506, 502101

Abstract:

The present invention provides, in some embodiments, hybrid materials having reticulated vitreous carbon (RVC) and nanoparticles of a conductive, transparent metal oxide such as tin-doped indium oxide (ITO). The material can further include one or more transition metal catalysts, such as {Ru(Mebimpy)[′-((HO)OPCH)bpy](OH)}. Oxidation of water, benzyl alcohol, and other useful reactants is possible when the material is employed as an electrode.
