Out-of-Substrate Ag–Ag2O Nanoplates:
Surfactantless Photochemical Synthesis, Structural Evolution, and
Mechanistic Study
Posted on 2016-10-27 - 12:03
Two types of out-of-substrate
Ag–Ag2O nanoplates
were grown on a ZnO substrate through a surfactantless photochemical
method. First, the in situ photochemically synthesized Ag–Ag2O nanoparticles further crystallized into nanoplate-like superstructures
with rough surfaces and ragged edges. The nanoparticle-mediated crystallization
process was governed by a layer-by-layer crystallization mechanism.
Our study should help fundamentally understand the formation mechanism
of hierarchical nanoparticle superstructures. Under continuous UV
illumination, the hundreds of nanometer-sized rough nanoplates (i.e.,
the nanoplate-like superstructures of nanoparticles) can be transformed
into large smooth nanoplates with sizes of up to several micrometers.
The out-of-substrate Ag–Ag2O nanoplates/ZnO heterostructures
are potentially promising for photocatalytic applications.
