Sentence examples for mass activity for from inspiring English sources
The catalytic efficiency of prepared PtNSs/CNTs/CP electrode, as determined by the electrochemical active surface area and the catalyst mass activity for the MOR, were 1.39 times and 2.95 times better than those of a commercial Pt-black catalyst, suggesting that PtNSs/CNTs/CP electrode might be a good candidate for catalyst of MOR.
CO stripping and CV analysis of MC-supported Pt catalysts showed higher mass activity for electrochemical reactions under fuel cell conditions.
The combined features of optimized structure/surface electronic structure, high surface area and ultrafast charge transfer resulted in attractive intrinsic activity and markedly enhanced mass activity for ultrafine PBSCF-III nanofiber, indicating that it is a very promising candidate of the next-generation electrocatalysts for OER.
Remarkably, after accelerated degradation test through 2000 cyclic voltammetry, the mass activity for Pt/TiO2@RFC was well maintained at 689.5 mA mg−1, 3.3 times that of the commercial Pt/C (206.1 mA mg−1, decline of 40.17%).
Compared to the crystal platinum nickel phosphorus nanoparticles supported on carbon (PtNiPc/C) and PtNi/C, PtNiPa/C catalyst has more positive half-wave potential and higher mass activity for oxygen reduction reaction (ORR).
The enhanced catalytic activity at high potentials and stability of mass activity for the Co-doped Pt/CCC catalyst are attributed to the formation of compressive Pt lattice catalyst due to Co doping.
The specific and mass activities for oxygen reduction follow the order of nanoporous Pt75Fe25 > nanoporous Pt55Fe45 > PtFe/C > Pt/C.
Steady-state measurements via chronoamperometry (CA) showed a good stability against poisoning during methanol oxidation and higher mass activities for PdRh/C and Pd3Rh/C compared to Pt/C.
The results show that the NiO/N-CNFs catalyst has superior specific and mass activities for methanol oxidation over the other nickel based catalysts.
The mass activity of the amorphous Os thin film was over an order of magnitude higher than previously reported mass activities for carbon-supported polycrystalline Pt or Os catalysts.
The modified BDD electrodes by deposition of platinum have been tested for the oxidation of methanol, showing that multi-step deposition results in higher values of surface and mass activities for methanol oxidation than one-step deposition process.
