| 1 | Synthesis of LiFePO_4 in situ vapor-grown carbon fiber (VGCF) composite cathode material via microwave pyrolysis chemical vapor deposition显示文摘One of the most important factors that limits the use of LiFePO 4 as cathode material for lithium ion batteries is its low electronic conductivity.In order to solve this problem,LiFePO 4 in situ vapor-grown carbon fiber (VGCF) composite cathode material has been prepared in a single step through microwave pyrolysis chemical vapor deposition.The phase,microstructure,and electrochemical performance of the composites were investigated.Compared with the cathodes without in situ VGCF,the initial discharge capacity of the composite electrode increases from 109 to 144 mA h g-1 at a 0.5-C rate,and the total electric resistance decreases from 538 to 66.The possible reasons for these effects are proposed. | DENG Fei ZENG XieRong ZOU JiZhao HUANG JianFeng SHENG HongChao XIONG XinBo QIAN HaiXia LI XiaoHua | 2011 | Chinese Science Bulletin2011，56，17： | 4 |

| 18 | Microwave-assisted synthesis of Cr_(3)C_(2)@C core shell structure anchored on hierarchical porous carbon foam for enhanced polysulfide adsorption in Li-S batteries显示文摘In this paper,we use microwave reduction strategy to synthesize a new bi-functional sulfur host material at the service of cathode substrate for lithium-sulfur batteries(LSBs),the composite is made of hierarchical porous carbon foam supported carbon-encapsulated chromium carbide nano-particles(Cr_(3)C_(2)@C/HPCF),in which the well-distributed conductive Cr_(3)C_(2) nano-particles can act as powerful chemical adsorbent and are effective in restraining the shuttle effect of lithium polysulfides(LiPSs).Test results show that the Cr_(3)C_(2)@C/HPCF based sulfur electrodes with 75 wt.%of sulfur exhibit a high initial discharging capacity of 1,321.1 mAh·g^(−1) at 0.1 C(3.5 mg·cm^(−2)),and a reversible capacity can still maintain stability at 1,002.1 mAh·g^(−1) after 150 cycles.Even increasing the areal sulfur loading to 4 mg·cm^(−2),the electrodes can still deliver an initial discharging capacity of 948.0 mAh·g^(−1) at 0.5 C with ultra-slow capacity decay rate of 0.075%per cycle during 500 cycles.Furthermore,the adsorption energy between the Cr_(3)C_(2) surface and LiPSs as well as theoretic analysis based on first-principles is also investigated. | Xierong Zeng Jianxin Tu Shuangshuang Chen Shaozhong Zeng Qi Zhang Jizhao Zou Kezhi Li | 2021 | Nano Research2021，14，7： | 0 |
| 19 | Preparation of Bioactive Calcium Phosphate Coatingon Porous C/C Substrate by a Novel Deposition Technique显示文摘A novel heat substrate technique,high frequency inductive heat deposition(IHD),was introduced to coat porous carbon materials,C/C and carbon felt to improve their bioactivity.The morphologies, composition and microstructure of the resulting coatings were examined by scanning electron microscopy(SEM), energy dispersive spectra(EDS),X-ray diffractometer(XRD)and Fourier transform infrared spectroscopy (FTIR).The results show that,the calcium phosphate consisted of non-stoichiometric,CO3-containing and plate-like octacalcium phosphate(Ca 8-x H 2 (PO 4 ) 6 ,OCP)could uniformly cover the entire porous surfaces of carbon materials.Good adhesion of the coating to carbon material substrates was observed. | XIONG Xinbo ZENG Xierong LI Xiaohua Xie Shenghui ZOU Chunli | 2008 | Journal of Wuhan University of Technology(Materials Science)2008，23，4： | 0 |
| 20 | An Iron-Based High-Entropy Alloy with Highly Efficient Degradation for p-Nitrophenol显示文摘High-entropy alloys(HEAs)have attracted widespread attention due to their excellent mechanical properties.However,their functional properties arising from the supersaturated solid solution state can be improved.Advanced oxidation processes(AOPs)are considered to be an effective method for decomposing organic pollutants,and HEAs are proposed as effective candidates for AOP catalysts.Currently,several HEAs used for organic pollutant degradation are prepared through mechanical alloying.In this work,FeAlCoNi and FeAlCoNiB Fenton-like catalysts were prepared by single roll melt spinning and subsequent ball milling techniques.We found that the FeAlCoNiB HEA exhibits highly efficient degradation for p-nitrophenol(p-NP).The degradation efficiency of FeAlCoNiB is 120 times higher than that of FeAlCoNi,which confirms that boron functions effectively during the degradation process.FeAlCoNiB has a better degradation efficiency than pure iron powder and a degradation efficiency comparable to that of the amorphous Fe_(78)Si_(11)B_(11) alloy.Additionally,the degradation efficiency of FeAlCoNiB_(X) increases(k values from 0.13 to 0.55 min^(−1))when the boron content increases from an X value of 0.25 to 1.25.We speculate that Fe_(2)B favors the degradation process and promotes zero-valent iron to decompose organic pollutants through a galvanic cell effect.Possible p-NP degradation pathways are proposed after LC–MS analysis.This study provides a new series of HEA Fenton-like catalysts,which have the potential to be prepared into bulk devices for industrial applications. | Shenghui Xie Xiang Liao Xierong Zeng Haipeng Yang Liang He | 2022 | Acta Metallurgica Sinica(English Letters)2022，35，10： | 0 |
