The introduction of MoS2 improves the electrochemical performance of NiFeCr-LDH. The polarization curve shows that the potential of composite material is only 1.50 V at a current density of 10 mA cm, which is far superior to commercial precious metal catalysts. In addition, the stability ...
In this context, the electrochemical detection of Cr(VI), Sb(V), As(III), As(V) and Tl(III) has been performed using differential pulse anodic stripping voltammetry (DPASV) on a glassy carbon electrode modified with CoFe2O4@NiFe LDH. The anticipated active sites, such as the surface ...
Furthermore, a larger active surface area for NiFeCr LDH is provided by the ultrathin layered structure of MoS2, increasing the number of active sites and encouraging the OER. On the other hand, the introduction of Cr element increased the density of the catalytic center and provided additional...
NiFe_2O_4/ZnAl-LDH吸附Cr(Ⅵ)采用共沉淀法合成磁性复合材料NiFe_2O_4/ZnAl-LDH,通过静态吸附试验考察复合材料去除水中Cr(VI)的性能,系统地研究了溶液初始p H值,吸附剂投加量,吸附时间和温度等因素对Cr(VI)去除效果的影响.结果表明,当溶液初始p H值为2,初始Cr(VI)浓度为50 mg·L-1,吸附剂投加量为...
The adsorption performance of the GO-NiFe LDH composite and pure NiFe LDH for three anionic pollutants, namely, Congo red (CR), methyl orange (MO) and hexavalent chromium ion [Cr(VI)] is systematically investigated. The presence of GO in the GONiFe LDH composite leads to the better ...
