CuO, a p-type semiconductor with a narrow band gap
of 1.2 eV, has attracted a great attention for its applications
in catalysis [1, 2], Li-ion electrode material , solar
cells , sensors [5, 6], solar selective absorbing coating
The size and shape of CuO nanostructures control the
properties of CuO, which determine the activity of CuO
. The methods of CuO fabrication include precipitation
method , ultrasonic irradiation , thermal treatment
, hydrothermal method [12, 13], ionothermal route
, ball-milling method , electrochemical route
, wet chemical route [17, 18], etc. Among the various
routes, wet chemical route was one of the most promising
synthesis methods because of its low cost, high yield and
high-quality production . Whereas, the normal routes
of the synthesis process of CuO are tedious.
Recently, Ba et al. , Shaabani et al. , and Zhu et
al.  prepared CuO nanostructures via an intermediate
by combining wet chemical method with
thermal decomposition method. Darezereshki et al. ,
Zhang et al. , Bakhtiari et al.  and Zhang et al.
 synthesized CuO nanostructures from basic copper
salts by direct thermal decomposition method.
The one-pot wet-chemical method is simple and
environmentally friendly in the fabrication of CuO due
to its low temperature, mild alkaline conditions, and short
reaction time. In our initial work , CuO was prepared
by wet chemical method. In this
article, an one-pot synthesis of CuO nanoparticles from
copper salt in alkaline condition through wet chemical
route was fabricated. The possible pathways of CuO
nanoparticles were studied through a series of control
experiments. Also, CuO nanoparticles were applied to the
thermal decomposition of ammonium perchlorate (AP).
Materials. The reagents including CuSO
, anhydrous ethanol were all of
analytical grade and used in this work without any further
puriﬁ cation. Distilled water was used throughout the
Synthesis of CuO nanoparticles. In a typical process,

Abstract—Sphere-like CuO products aggregated by numerous nanoparticles were fabricated by a low-temperature
(50°C) wet chemical method using CuSO
O as precursor. The possible formation processes of CuO were
investigated by a series of single-factor experiments. The CuO was characterized by X-ray diffraction, scanning
electron microscopy, transmission electron microscopy, high-resolution transmission electron microscopy, selected-
area electron diffraction. Furthermore, the application of CuO nanoparticles on the thermal decomposition of
ammonium perchlorate was studied with 2 wt % CuO nanoparticles at heating rates of 10, 15, 20, and 25°C min
from 35 to 500°C.
