高锡化学镀Ni-Sn-P合金工艺
关键字:化学镀;Ni-Sn-P合金 高锡 添加剂
研究了在酸性条件下,以次亚磷酸钠为还原剂、多种配位剂共存、并有稳定剂和光亮剂存在条件下,镀层含锡量较高的化学镀Ni-Sn-P合金的工艺条件。在该条件下施镀,镀速较快、镀液稳定、镀层光亮、镀层组成为P 7.48%﹑Sn 12.76%、Ni 78.12%和Fe 1.64%,硬度HV为487.14。

Inorg. Chem. Comm., A novel highly selective colorimetric sensor for Ni(II) ion using coumarin derivatives
关键字:Coumarin, Colorimetric sensor
A new coumarin based colorimetric nickel sensor 1 with high selectivity and sensitivity toward Ni2+ ion was reported. The absor ption maximum of 1 shows a large red shift from 341 nm to 540 nm (Δ = 200 nm) in the presence of Ni2+ ion, and the resulted color change from colorless to pink upon addition of Ni2+ is very easily observed by the naked eye, while other metal ions, such as Zn2+,Cd2+, Cu2...

Construction of NiMoO4/CoMoO4 nanorod arrays wrapped by Ni-Co-S nanosheets on carbon cloth as high performance electrode for supercapacitor
Abstract: The NiMoO4/CoMoO4 nanorod arrays wrapped by Ni-Co-S nanosheets were successfully grown on the surface of carbon cloth (NCMOS@CC) by combining of hydrothermal and electrochemical deposition methods. And the as-prepared NCMOS@CC showed good flexibility. The obtained NCMOS@CC as electrode materials were tested in a three-electrode system, showing a pretty good specific capacitance of 778....

Hierarchical mesoporous Zn-Ni-Co-S microspheres grown on reduced graphene oxide/nickel foam (rGO/NF) for asymmetric supercapacitors
Abstract: In this work, hierarchical mesoporous Zn-Ni-Co-S-rGO/NF microspheres have been prepared by hydrothermal, sulfurization, and subsequent calcination process. The effect of different sulfurization time on the morphology and capacitance of composites was tested. The high electrochemical performance of (Zn-Ni-Co-S-rGO/NF) composite was obtained when the sulfurization time was...
