▎ 摘　　要

Functionalized chemically converted graphene (f-CCG) with high solubility has been incorporated into fullerene C-60 cluster and functionalized single-walled carbon nanotubes (f-SWNT)-fullerene C-70 hybrid cluster to form binary (i.e., graphene and fullerene) and ternary (i.e., graphene, fullerene, and carbon nanotubes) nanocarbon composites in solution processes for the first time. Electrophoretic deposition of the composites yielded the corresponding films on nanostructured SnO2 electrodes for photoelectrochemical devices. The device with the f-CCG-C-60 composites with an optimized weight ratio exhibited a higher incident photon-to-current efficiency (IPCE) value (6.0% at 400 nm) than that with the C-60 single-component cluster (5.1%). Electronic communication between C-60 clusters and f-CCG may facilitate the electron transport to the SnO2 electrode. However, the incorporation of f-CCG into f-SWNT-C-70 cluster made an adverse effect on photocurrent generation efficiencies because f-CCG inhibited formation of the porous network structure constructed by the f-SWNT-C-70 clusters. These results obtained here will provide valuable information on the design of optoelectronic devices composed of all-nanocarbon materials. (C) 2013 The Electrochemical Society. All rights reserved.
