“…As a photocatalyst, ZnS has been examined for degradation of water pollutants, reduction of toxic heavy metals and water-splitting for H 2 evolution [6][7][8][9][10][11]. Therefore, much effort has been made in the past decade to the controlled preparation of ZnS nanostructures with various forms including nanorods [12,13], nanowires [14][15][16], nanosheets [17], nanobelts [18][19][20], nanotubes [21,22], nanosaws [23], and nanoparticles [24][25][26][27]. Although these low dimensional nanomaterials exhibit lots of special properties, in comparison with them, the complex 3D architectures constructed by nanoscale building blocks possibly provide a great deal of opportunity to explore their novel properties due to their complex structures.…”
