A microwave-assisted rapid route to synthesize ZnO/ZnS core–shell nanostructures via controllable surface sulfidation of ZnO nanorods

Photocatalytic studies of CdS nanoparticles assembled on carbon microsphere surfaces with different interface structures: from amorphous to graphite-like carbon

“…Meanwhile, a great deal of metal oxide and sulfide semiconductors are found to be used as photocatalysts in purifying wastewater. [1][2][3] As a II-VI semiconductor compound, cadmium sulfide (CdS) has attracted considerable interest in optoelectronic applications because of its band gap energy (2.42 eV) in the visible-light region. 4,5 CdS is also generally considered to be one of the best photocatalysts for its unique photochemical and photophysical properties such as high-efficiency, photochemical stability, and low-cost in wastewater treatment.…”

Facile formation of Ag2WO4/AgX (X=Cl, Br, I) hybrid nanorods with enhanced visible-light-driven photoelectrochemical properties

“…As an excellent photocatalyst for water and air purification, one-dimensional (1D) semiconductor nanostrucutures, including nanowires, nanorods, nanotubes, and nanobelts, etc., have demonstrated significantly enhanced catalytic efficiency because of their high aspect ratio, enhanced light scattering, and absorption, rapid transport of free electron along the long axis, and efficient utilization of electronhole pair [4][5][6][7][8][9]. Distinct from their single component counterparts, semiconductor hybrid nanostructures with a staggered alignment of band edges at the hetero-interface can improve spatial charge separation of the electron and hole in different parts of the heterostructure for photocatalytic and photovoltaic applications [10][11][12][13][14][15][16]. To take advantage of both materials, the fabrication of 1D semiconductor hetero-nanostructures with controllable shape and size is extremely important from the viewpoints of both fundamental research and technical applications.…”

Structure-dependent gas detection ability of clustered ZnS crystallites with heterostructure and tube-like architecture

“…A high density of the surface defects in the ZnO crystals has been posited to quench the band-to-band emission of ZnO [22]. A similar absence of the near-band-edge emission of ZnO has been shown in the ZnS/ZnO hybrids prepared using a chemical solution route [23]. For ZnO rods subjected to a 5-h sulfidation treatment, the visible emission band position shifted to approximately 525 nm and the intensity of the band increased.…”
