A simple biomolecule-assisted hydrothermal approach to antimony sulfide nanowires

Biomolecule‐Assisted Synthesis and Electrochemical Hydrogen Storage of Porous Spongelike Ni3S2 Nanostructures Grown Directly on Nickel Foils

“…[4] In a very recent communication, Qian and co-workers synthesized antimony sulfide nanowires in the presence of cysteine. [5] This inspired us to explore a simpler and more economical method to prepare metal sulfides by using a small biomolecule. Moreover, most of the synthesized metal sulfides were in powder form.…”

“…[6] Recently, the oriented growth of sulfide nanomaterials on substrates was considered as a solution to this difficult problem. [5] Zhang et al developed a hydrothermal approach to fabricate oriented Abstract: Nanothread-based porous spongelike Ni 3 S 2 nanostructures were synthesized directly on Ni foil by using a simple biomolecule-assisted method. By varying the experimental parameters, other novel Ni 3 S 2 nanostructures could also be fabricated on the nickel substrate.…”

Synthesis of heteroarchitectures of PbS nanostructures well-erected on electrospun TiO2 nanofibers

“…As we known, cysteine consists of -SH, -NH 2 and -COOH functional groups, which enable it to chelate strongly with inorganic cations, and to form metal-cysteine complexes that can serve as precursors for the preparation of inorganic nanomaterials [24,25]. In our reaction system, as the literatures reported [26][27][28][29], the -SH and -COOH groups of cysteine could chelate with lead cation to form initial precursor complexes [Pb(C 3 H 5 O 2 NS) and PbðC 3 H 5 O 2 NSÞ 2À 2 ] (I). Subsequently, the hydroxyl O À of carboxyl and amine groups of Pb-cysteine complexes could react with the surface hydroxyl groups and oxygen of TiO 2 nanofibers (II) [18].…”

Preparation of γ-MnS hollow spheres consisting of cones by a hydrothermal method

“…All the diffraction peaks can be indexed to the pure hexagonal structured g-MnS with lattice There are several functional groups in the L-cysteine molecule, such as ÀNH 2 , ÀCOOH, and ÀSH, which have a strong tendency to coordinate with inorganic cations. Some metal sulfide nanostructures have been prepared in the presence of cysteine, where cysteine can act not only as a complexing agent but also as a sulfur source and structure-directing molecule [6,[19][20][21]. It is rationally speculated that L-cysteine can coordinate with Mn 2+ in our system.…”
