Facile synthesis of size-tunable Cu39S28 micro/nano-crystals and small-sized configuration enhanced visible-light photocatalytic activity

Mesocrystal precursor transformation strategy for synthesizing ordered hierarchical hollow TiO2 nanobricks with enhanced photocatalytic property

“…As we know, the photooxidation of organic contaminants over photocatalysts could be mainly due to active species such as ˙OH and holes. 31 The catalytic ability of TiO 2 is closely related to the amount of hydroxyl radicals. To further confirm the photocatalytic activity, we adopted a photoluminescence test for ˙OH radical analysis.…”

Nanostructured metal sulfides for energy storage

“…The Cu-S system exhibits many different stoichiometric compositions, over a wide range, from the copper-decient side to the copper-rich side, including villamaninite (CuS 2 ), covellite (CuS), yarrowite (Cu 1.12 S), spionkopite (Cu 1.39 S), geerite (Cu 1.6 S), anilite (Cu 1.75 S), digenite (Cu 1.8 S), djurleite (Cu 1.96 S) and chalcocite (Cu 2 S). [87][88][89][90] Owing to the variations in compositions, complex structures, nanocrystalline morphologies, and valence states, these copper suldes are of great interest in a wide range of applications, including photocatalysis, 91 optoelectronic devices, 92 sensors, 93 LIBs, 94 and SCs. 95 Recently, metal-like CuS and Cu 2 S with good electrical conductivities, e.g., 9.5 Â 10 À3 S cm À1 for CuS and 8.3 Â 10 À4 S cm À1 for Cu 2 S, 96 have become of particular interest in LIB and SC applications in view of their high capacities/capacitances.…”

CuS hierarchical hollow microcubes with improved visible-light photocatalytic performance

“…The cOH could oxidize MB into small molecules like CO 2 , H 2 O. 42 It has been demonstrated that because of their high oxidative capacities, the photo-generated oxidant species are in favor of oxidizing organic contaminants. 43,44 The obtained CuS HHCs possess the highest photocatalytic activity among all the as-prepared products due to the following several factors.…”
