Further using rotating disk electrode (RDE) measurements and Koutechy-Levich analysis, the overall electron transfer number in the catalyzed ORR on 40%NiPc/C was found to be 2.8, suggesting the catalyzed ORR proceeds via both the 2e- transfer reduction and the 4e- transfer reduction.
The RDE voltammograms for ORR were performed at various rotation rates and the data were using the Koutecky-Levich (K-L) equations [8]: ik = i·id/(id - i) (1) id = Bω1/2 (2) B = 0.2nFSCo2Do22/3ν-1/6 (3) Where B is the Levich slope, ω is the rotation rate, n is the electron transfer number per oxygen molecule, F is Faraday constant, S the electrode surface area, CO is the concentration of oxygen, DO is the diffusion coefficient of O2 in different electrolytes, ν is the kinetic viscosity and the constant 0.2 is adopted when rotation speed is expressed in revolutions per minute.
It can be calculated the electron transfer numbers per oxygen molecule in the overall reduction process are 2.93, 2.76 and 2.61, respectively.
These data suggest that the ORR on NiPc/C-800 electrode process via both the 2e- transfer reduction and the 4e- transfer reduction process.
For NiPc/C-non, NiPc/C-600 and NiPc/C-900, the electron transfer numbers are all determined to be about 2.2, which suggests that the oxygen reduction catalyzed on these electrodes are the 2e- reduction process leading to great deal of H2O2.

Based on the analysis of major problems on energy saving and emission reduction for China’s logistics industry, this paper proposes the strategic objectives and strategic focus to energy saving and emission reduction of the logistics industry, and discusses possible ways for the achievement of energy saving and emission reduction in the logistics industry from multiple aspects.
Strengthening energy saving and emission reduction is in urgent need to answer to global climate change.
Building a socialization logistics information platform under the government's support can achieve the resource sharing, data sharing and information exchange of different logistics departments and different logistics enterprises, and create conditions for the smooth flow of logistics information exchange and make effective convergence among different logistics activities with the achievement of resources integration and configuration optimization.
According to the requirement of the new situation of global energy saving and emission reduction, China should increase the policy support for the development of logistics industry and focus on the incentives of energy saving and emission reduction, to reduce the economic benefit of logistics cost and by the logistics enterprises, make it be in line with the social benefit of energy saving and emission reduction and make the owners of logistics bear the low-carbon responsibility initiatively, through the formation of policy incentives such as energy saving and emission reduction subsidies, tax support policies and preferential loans and the guidance of behaviors of logistics owners.

The datum showed that their sulfate reduction capacity increased by 0.1855 and 0.4820 than original bacteria respectively.
Besides this, the sulfate reduction capability of wild SRB separated from the nature are generally low, therefore, to study how to improve the reduction capability of SRB also becomes more and more important.
In this study, SRB with higher reduction capability were obtained through the enrichment, separation and purification.
