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 C70 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. Elec-trophoretic deposition of the composites yielded the corresponding films on nanostructured SnO_2 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 SnO_2 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.
