Ni0.85Se Nanostructures with Plate-like and Particle Morphologies and Their Catalytic Performances

Abstract

Ni0.85Se plate-like nanostructures (PNSs) had been prepared by a template method, and by a similar process, the Ni0.85Se nanoparticles were obtained by using NiCl2·6H2O as the nickel source. The Ni0.85Se nanostructures (NSs) with different shapes exhibited high catalytic activities for hydrogenation of 4-nitrophenol (4-NP) with excess NaBH4. To the best of our knowledge, this may be the first report on using Ni0.85Se NSs as catalysts for the reduction of 4-NP.

Ambient Aqueous Synthesis of Ultrasmall Ni0.85Se Nanoparticles for Noninvasive Photoacoustic Imaging and Combined Photothermal-Chemotherapy of Cancer

“…As shown in Figure a, the Ni 2p spectrum could be best fitted with two spin–orbit doublets, characteristic of Ni 2+ and Ni 3+ , as well as two shakeup satellites (Sat.) . The binding energy of ca.…”

“…Encouraged by the phenomenon that hyperthermia would promote the cellular uptake of chemotherapeutic drug, the combination of PTT and chemotherapy can lead to a noteworthy enhanced therapeutic outcome . Thereafter, plenty of PTT agents, including gold nanostructures, − carbon-based nanomaterials, ,− palladium nanosheets, transition-metal chalcogenides, , and numerous organic polymeric nanoparticles, ,,, have been developed for synergistic PTT-chemo cancer treatment. However, limited nanomaterials have been explored as both PTT agents and drug carriers up to now for combined photothermal-chemo cancer therapy.…”

Thermosensitive Hydrogel Loaded with Nickel–Copper Bimetallic Hollow Nanospheres with SOD and CAT Enzymatic-Like Activity Promotes Acute Wound Healing

“…The chemical composition and electronic structure were further analyzed by XPS (Figure K). As shown in Figure L, 932.08 and 933.58 eV correspond to Cu 0 2p 3/2 and Cu 2+ 2p 3/2 , respectively, while 941.78 eV corresponds to the satellite peak of Cu 2+ 2p 3/2 . − The peaks at 872.78 and 855.08 eV correspond to Ni 2+ 2p 1/2 and Ni 2+ 2p 3/2 , respectively, whereas those at 879.08 and 860.68 eV correspond to the satellite peaks of Ni 2+ 2p 1/2 and Ni 2+ 2p 3/2 , respectively (Figure L). − The Ni and Cu species in the Ni 4 Cu 2 hollow nanospheres existed in two states: Ni 2+ /Cu 0 and Ni 2+ /Cu 2+ . Thus, there were also oxidized copper/nickel species on the surface of the Ni 4 Cu 2 metal hollow nanospheres.…”

Synthesis, characterization and application of superhydrophobic low-cost Cu and Al nanoparticles

“…Hence, the reduction of NiP using various catalyst systems is the only way to reduce the pollution caused by the NiP. Currently, various catalyst systems such as iron niobate [6], hydroxyapatite [7], Au nanoparticles (NP) [8], Au-SiO 2 [9], layered double hydroxides (LDH) [10], TiO 2 [11], Al 2 O 3 [12], Pd-Ag [13], AC-Ag [14], Au-CeO 2 [15], aminoclay-Fe NP [16], Clay-Pt [17], Fe 3 O 4 [18], Ni-Se [19] and Ni-P [20] are used for the reduction of NiP. Through study of the literature, any report based on the Cu and Al nanoparticles as a catalyst for the reduction of NiP in the presence of NaBH 4 is not found.…”
