| 1 | Covalent organic frameworks derived hollow structured N-doped noble carbon for asymmetric-electrolyte Zn-air battery显示文摘We report a relatively low-temperature molten salt strategy to prepare hollow structured N-doped noble carbon(h-NNC) with highly desirable features of ultra-large surface area(1957 m^2 g^(-1)) and high graphitization, endowing the h-NNC with high activity toward catalysis of oxygen reduction reaction in acidic medium. The h-NNC is applied as cathode catalyst of an asymmetrical-electrolyte Zn-air battery, which exhibits an open circuit voltage of 2.11 V, a power density up to 270 mW cm^(-2),and an energy density of 1279 W h kg^(-1), behaving advantages over the conventional Zn-air batteries. | Pingwei Cai Xinxin Peng Junheng Huang Jingchun Jia Xiang Hu Zhenhai Wen | 2019 | Science China Chemistry2019，62，3： | 6 |
| 2 | Microwave-Assisted Decarboxylation of Sodium Oleate and Renewable Hydrocarbon Fuel Production显示文摘The carboxyl terminal of sodium oleate has a stronger polarity than that of oleic acid;this terminal is more likely to be dipole polarized and ionically conductive in a microwave field.Sodium oleate was used as the model compound to study the decarboxylation of oleic acid leading to hydrocarbon formation via microwave-assisted pyrolysis technology.The pyrolysis gas,liquid,and solid products were precisely analyzed to deduce the mechanism for decarboxylation of sodium oleate.Microwave energy was able to selectively heat the carboxyl terminal of sodium oleate.During decarboxylation,the double bond in the long hydrocarbon chain formed a p-πconjugated system with the carbanion intermediate.The resulting p-πconjugated system was more stable and beneficial to the pyrolysis reaction(decarboxylation,terminal allylation,isomerization,and aromatization).The physical properties of pyrolysis liquid were generally similar to those of diesel fuel,thereby demonstrating the possible use of microwaves for controlling the decarboxylation of sodium oleate in order to manufacture renewable hydrocarbon fuels. | Wang Yunpu Liu Yuhuan Ruan Rongsheng Wen Pingwei Wan Yiqin Zhang Jinsheng | 2013 | China Petroleum Processing & Petrochemical Technology2013，15，3： | 5 |
| 3 | Effects of Microwave Torrefaction with Mg(OH)2 on Characteristics of Bio-oil from Co-pyrolysis of Straw Stalk and Soapstock显示文摘This study investigated the effects of torrefaction with Mg(OH)2 on the properties of bio-oil formed from the microwave-assisted catalytic fast co-pyrolysis of straw stalk and soapstock.The effects of torrefaction temperature and residence time on the yield and composition of bio-oil were discussed.Results showed that the torrefaction temperature and residence time remarkably influenced the yield and composition of bio-oil.With the increase in temperature and time,the bio-oil yield and the proportion of oxygen-containing compounds decreased,while the proportion of aromatic compounds increased.When the feedstocks were subject to torrefaction reaction for 20 min at 260°C,the proportion of oxygen-containing compounds decreased from 29.89%to 16.49%.Meanwhile,Mg(OH)2 could render the deoxidization function of torrefaction process increasingly noticeable.The proportion of the oxygen-containing compounds reached a minimum(14.41%),when the biomass-to-Mg(OH)2 ratio was 1:1. | Wen Pingwei Zhou Yue Dai Leilei Wang Yunpu Liu Yuhuan Ruan Roger | 2019 | China Petroleum Processing & Petrochemical Technology2019，21，3： | 1 |

| 5 | 320-fold luminescence enhancement of [Ru(dpp)3]Cl2 dispersed on PMMA opal photonic crystals and highly improved oxygen sensing performance显示文摘Ru complexes([Ru(dpp)3]Cl2)were spin coated on poly(methyl methacrylate)(PMMA)opal photonic crystals(PhCs),and a,320-fold luminescence enhancement was observed compared to that on glass,which is the largest luminescence enhancement of dye molecules by the modulation of three-dimensional(3D)PhCs reported until now.The enhancement mechanism was carefully examined and it was shown that the luminescence of[Ru(dpp)3]Cl2 depended on the molecule concentration and temperature.It can be concluded that the suppressed non-radiative relaxation among the molecules and the field enhancement both contribute significantly to the luminescence enhancement.The PMMA PhC/Ru complex composites were then tested for their intracellular oxygen sensing and cell imaging properties;these composites effectively improved the limit of detection(LOD)and the brightness of the cell images. | Pingwei Zhou Donglei Zhou Li Tao Yongsheng Zhu Wen Xu Sai Xu Shaobo Cui Lin Xu Hongwei Song | 2014 | Light(Science & Applications)2014，3，1： | 1 |
