Developing low-cost,efficient oxygen reduction reaction(ORR)catalysts to replace Pt-based materials is urgently required for the application of Zn-air batteries(ZABs)and microbial fuel cells(MFCs).In this work,meso-microporous carbon fibers with tunable defect density were synthesized by carrageenan fibers.A highly defective carbon fiber(HDCFs)was produced which exhibited an outstanding ORR catalytic activity,reaching to the half-wave potential of 0.841 and 0.44 V in alkaline and neutral electrolytes,*** HDCFs can also act as highly efficient air cathodes for ZABs(delivered potential of 0.69 V and power density of 220 mW cm^(–2) at 300 mA cm^(–2))and MFCs(high power density of 69.7 mW cm^(–2)).Simulation by the density functional theory indicated that a high density of defections in a carbon based framework can remarkably modulate the electrical *** instance the charge entrapments in the carbon active sites may reduce the energy barrier of ORR.

尽管现行土地制度的形成和发展有其历史原因,但其割裂城乡、阻碍流动的弊端逐步显现,成为阻挡社会经济发展的障碍之一,推动农村土地制度改革已成为实践和理论上的共识。党的十八届三中全会提出,要充分发挥市场在资源配置中的决定性作用。土地是基础性资源,农村土地只有走向市场化,才能更好提高土地的配置效率,进而提高社会整体效率。本文试图通过对我国农村土地制度的历史沿革和现有农村土地制度问题现状进行分析,进一步探讨农村土地市场化滞后原因,并对农村土地制度市场化改革提出政策建议。
