“…6,7 As an important p-type semiconductor, CuS is a promising material due to its abundance, non-toxicity and wide applications in supercapacitors, Li-ion batteries, biosensors, gas sensors, catalysts, photothermal conversion, and solar cells. 19 And in order to improve application performance, plenty of tries have been dedicated to synthesize CuS 3D hierarchical micro/nano-architectures with various morphologies such as rattan-ball-like and carnation-like microflowers, 20 shuttle-like bundles, 16 superstructures assembled by micro/nanotubes and nanoflakes, 19 wool-balllike microspheres, 21 concave polyhedron superstructures, 22 ball-flowers, 23 snowflake-like and flower-like microspheres, 24 complex concaved cuboctahedrons, 25 and so on. 19 And in order to improve application performance, plenty of tries have been dedicated to synthesize CuS 3D hierarchical micro/nano-architectures with various morphologies such as rattan-ball-like and carnation-like microflowers, 20 shuttle-like bundles, 16 superstructures assembled by micro/nanotubes and nanoflakes, 19 wool-balllike microspheres, 21 concave polyhedron superstructures, 22 ball-flowers, 23 snowflake-like and flower-like microspheres, 24 complex concaved cuboctahedrons, 25 and so on.…”
