Self-Assembled Three-Dimensional Graphene-Based Aerogel with Embedded Multifarious Functional Nanoparticles and Its Excellent Photoelectrochemical Activities
Here,
a graphene-based aerogel embedded with two types of functional
nanoparticles shaped in a three-dimensional (3D) cylindrical architecture
was prepared by a facile one-pot hydrothermal process. During the
hydrothermal reaction, the uniformly dispersed TiO<sub>2</sub> (P25)
and CdS nanoparticles were loaded on the graphene sheets, and the
resulting composites were self-assembled into a 3D interconnected
network. It is shown that the graphene-based hydrogel and aerogel
are appropriate and robust hosts for anchoring different functional
nanostructured particles. The outstanding synergistic effect of this
ternary graphene-based nanocomposite aerogel is also proved by the
excellent photoelectrochemical activity of the as-prepared novel nanocomposite
(CdS/P25/graphene) aerogel. As a new photocatalyst, the CdS/P25/graphene
aerogel exhibits enhanced light absorption, improved photocurrent,
extremely efficient charge separation properties, and superior durability.
These excellent properties indicate that the as-prepared CdS/P25/graphene
aerogel may have a great potential application in photoelectrochemical
hydrogen production from water reduction under sunlight. More importantly,
in this study, a significant and pragmatic consideration of integrating
multifarious functional nanoobjects into the 3D graphene-based aerogel
has been clearly proposed. This could provide new insights into the
preparation of functional nanocomposites and facilitate their applications
in related areas
