-CNTs/PI catalyst. Key words: Pd micro-nanoparticles; graphene/polyimide membrane; carboxyl carbon nanotubes/polyimide membrane; electro catalytic oxidation; formic acid; electrochemical deposition 1... and 5 mmol/L PdCl2 solution at a scan rate of 10 mV/s. It can be seen that there are three coupled reduction-oxidation peaks on the COOH-CNTs/PI and Gr/PI membrane electrodes. A couple of reduction......
J. Cent. South Univ. (2016) 23: 1318-1325 DOI: 10.1007/s11771-016-3182-1 Reduction mechanism of Fe2O3-Cr2O3-NiO system by carbon ZHANG Yan-ling(张延玲), GUO Wen-ming(郭文明), LIU Yang(刘洋), JIA Xin-lei(贾昕磊...: Isothermal experiments on the reduction of Fe2O3-Cr2O3-NiO (molar ratio of Fe-to-Cr-to-Ni is 3:2:2) by graphite were carried out at 1350–1550°C, and effects of various factors on reduction degree were......
, such as low reduction potential as cathode materials or high reduction potential as anode materials. Here, the influence of chemical functionalities that are capable of either electron donating or electron withdrawing groups on the reduction potential and charge-discharge performance of anthraquinone (AQ) based system is studied. The cyclic voltammetry results show that the introduction of two -OH......
