The results showed that the catalytic activity of TNCuPc/AF-MWCNTs towards oxygen reduction was a two-step, two-electron process for oxygen reduction.
CV of GC/ TNCuPc shows two reduction peak ( −0.45 and -0.74 V vs.
and (c) TNCuPc/AF-MWCNTs , the oxygen reduction peaks were at similar positions(-0.50 and -0.75V vs.
From the result, GC/TNCuPc shows a two-electron process for oxygen reduction (Fig. 8A).
However, GC/TNCuPc/AF-MWCNTs led to a two-step, two-electron process for oxygen reduction.

The Rough Set Theory The Rough sets theory is a mathematical formalism to deal with incomplete data, uncertainty in knowledge discovery [1].
It can not only efficiently analyze and process the imprecise, inconsistent, half-baked information, but also can discover hidden knowledge and reveal the potential laws through data reasoning.
The main advantage of rough set theory in data analysis is that it does not need any preliminary or additional information about data comparing with probability analysis method in statistics.
Value Reduction of Decision Table The decision table after the attribute reduction should do the value reduction.

To properly cope with the problems and meet the demand of high performance, applying the fused and carbon thermal reduction method as well as combining with the advantages of EAF are necessary not only to produce high performance and low cost boride compound but also to succeed in the industrial production and application for this material.
To synthesize the high-performance boride compound and confirm the best choice of boron source, carbon source and agent, adjusting the category and addition of carbon source, boron source and the agent during the synthesis process, according to the analyzed data from XRD, is essential.
The main reason accounting for this phenomenon is attributed to constant adjustment of the category and addition amount of carbon source, boron source to complement the loss of boron source as well as the agent for crystal type conversion during the synthesis process according to the analyzed data of XRD.
Conclusions 1) The fused and carbon thermal reduction method is feasible to synthesize the boride composite powder.

Results and Discussion The X-ray diffraction data of the SBN61 samples are shown in Figure 1.
The oxygen-reduction degree increases in the order of SBN61Ar, SBN61H1100, and SBN61H1250.
According to the X-ray diffraction data, the lattice parameters and the theoretical densities of the samples were calculated, as shown in Table 1.
It indicates that oxygen-reduction can increase the κl of the SBN61 ceramics.
However, when the oxygen-reduction achieves some degree, the deepening of the oxygen-reduction degree has little effects on the increase of the κl.
