We report an efficient method for the synthesis of nickel phosphide NCs for the first time. The size of Ni2P NCs can be controlled by changing reaction temperature and OAm quantity. The phase of nickel phosphide NCs can be controlled by increasing reaction time.

Zinc acetate and ammonium bicarbonate are used as raw material, zinc oxide prepared by direct precipitation of new technology. This paper discusses the effection of the formation in zinc oxide from the reactant concentration of zinc acetate, HCO3-/Zn2+ molarity ratio, reaction temperature, reaction time and condition in thermal decomposition of basic zinc carbonate. Using transmission electron microscopy (TEM), thermogravimetric / differential thermal analysis (TG / DTA) and other methods, preparation of nano-ZnO are characterized. Good conditions for the better system of nano- ZnO are 0.75mol /L in the concentration of zinc acetate solution, 2.5:1 in bicarbonate of ammonia and zinc acetate molar ratio, 45 °C of reaction temperature, 1.0h of reaction time, and 350 °C in thermal decomposition temperature, 3.0h of pyrolysis time. Zinc oxide obtained average particle size is 20 ~ 80nm, for the hexagonal crystal form.

[M(NH3)5Cl][IrCl6], M = Co, Cr, Ru, Rh, and Ir, were proposed as single-source precursors for bimetallic alloys. Upon heating, compounds show endothermic effect which can be corresponded with Ir(iv) reduction and ligand exchange.

In this paper, an efficient method for producing lactic acid from glucose with nickel as a catalyst under hydrothermal conditions has been developed. The addition of nickel can improve the lactic acid yield efficiently under alkaline hydrothermal conditions. The highest lactic acid yield of 35% was obtained under the optimum conditions, i.e., reaction temperature 300 °C, reaction time 60 s, 0.5 mmol nickel and 2.5 M NaOH.

MoS2 microrods constructed by ultrathin nanosheets have been synthesized, for the first time, by thermal decomposition of intermediate (NH4)2MoS4 crystals, which could not only provide the single-source for both the molybdenum and sulfur atoms, but also served as the self-sacrificed template. The well-defined microstructure was characterized by XRD, SEM, TEM, XPS, BET, respectively. The results indicated that MoS2 microrods with uniform morphology were assembled by defective ultrathin nanosheets. Moreover, these MoS2 microrods exhibit superior catalytic activity with the apparent rate constant (κapp) of 0.161 min−1 for the reduction of 4-nitrophenol (4-NP) by NaBH4. Encouragingly, the MoS2 microrods still show evident activity for the reduction of 4-NP after five cycle tests, which has significant importance for the application in the reduction of 4-NP to p-aminophenol (4-AP). Also, this method can be extended to construct other kinds of metal dichalcogenides (TMDs).
