| 1 | Guest selectivity in the supramolecular host networks fabricated by van der Waals force and hydrogen bond显示文摘Here, the structural transformations of H4ETTC induced by coronene (COR) and selective adsorption behaviors of COR in different templates were investigated by seanning tunnelling microscope (STM). It was discovered that the assembled architecture of H4ETTC at the HOPG/ heptanoic acid interface depended on the concentration of COR, and the clusters of COR were obtained in the kagome nanoporous network of H4ETTC molecules at a high concentration of COR solution. In addition, COR clusters can also be formed in the hexagonal porous structure of hexaphenylbenzene (HPB) molecules modified by alkyl chains at the HOPG/heptanoic acid interface. When both H4ETTC and HPB assembly structures, based on hydrogen bonding and van der Waals force respectively, were selected as the host templates, COR showed selectivity for HPB template to form HPB/COR hexagonal host-guest architecture. Density functional theory (DFT) calculations were also performed to disclose the mechanisms involved. | Xuan Peng Yanfang Geng Min Zhang Faliang Cheng Linxiu Cheng Ke Deng Qingdao Zeng | 2019 | Nano Research2019，12，3： | 2 |
| 2 | Review on formation mechanism analysis method and control strategy of urban haze in China显示文摘Due to the rapid urbanization and industrialization,and excessive consumption of fossil fuel,haze weather characterized by PM2.5 has become a severe pollution problem in major Chinese cities recently,which has harmful effect on the air quality,visibility,clime system and human health.To indicate suitable directions for the prevention and control of haze pollution,the pollutant source apportionment and formation mechanism of urban haze should be figured out firstly.In this work,we briefly review the frequently-used methods for PM2.5 source apportionment and formation mechanism analysis of urban haze based on normal perspective in recent years.Furthermore,based on the new perspective of systematic methodology,the utilization of fault tree approach for the causation mechanism analysis of urban haze is significantly introduced and discussed.Finally,the recent progress on controlling strategies of urban haze in China is also synoptically introduced and discussed.It is expected that more effective tool/method can be found,developed and employed for the causation mechanism analysis and risk management of urban haze in China. | Weiqing Huang Lirong Cai Haifeng Dang Zhe Jiao Hongbo Fan Faliang Cheng | 2019 | Chinese Journal of Chemical Engineering2019，27，7： | 1 |

| 4 | Monoclinic Cu_(3)(OH)_(2)V_(2)O_(7)·2H_(2)O nanobelts/reduced graphene oxide:A novel high-capacity and long-life composite for potassium-ion battery anodes显示文摘Developing suitable anode materials for potassium-ion batteries(PIBs)remains a great challenge owing to the limited theoretical capacity of active materials and large radius of K+ion(1.38?).To solve these obstacles,by integrating the principles of multielectron transfer and rational porous crystal framework,we creatively propose the monoclinic Cu_(3)(OH)_(2)V_(2)O_(7)·2H_(2)O(CVO)as a novel anode for PIBs.Furthermore,inspired by the metastable nature of CVO under high temperature/pressure,we skillfully design a facile hydrothermal recrystallization strategy without the phase change and surfactants addition.Thus,for the first time,the porous composite of Cu_(3)(OH)_(2)V_(2)O_(7)·2H_(2)O nanobelts covered in situ by reduced graphene oxide(CVO NBs/r GO)was assembled,greatly improving the deficiencies of CVO.When used as a novel anode for PIBs,CVO NBs/r GO delivers large specific capacity(up to 551.4 m Ah g^(-1)at 50 m A g^(-1)),high-rate capability(215.3 m Ah g^(-1)at 2.5 A g^(-1))and super durability(203.6 m Ah g^(-1)at 500 m A g^(-1)even after 1000 cycles).The outstanding performance can be ascribed to the synergistic merits of desirable structural features of monoclinic CVO nanobelts and the highly conductive graphene 3D network,thus promoting the composite material stability and electrical/ionic conductivity.This work reveals a novel metal vanadate-based anode material for PIBs,would further motivate the subsequent batteries research on M_(3)(OH)_(2)V_(2)O_(7)-n H_(2)O(M;Co,Ni,Cu,Zn),and ultimately expands valuable fundamental understanding on designing other high-performance electrode materials,including the combined strategies of multielectron transfer with rational porous crystal framework,and the composite fabrication of 1D electrode nanostructure with conductive carbon matrix. | Liming Ling Xiwen Wang Yu Li Chenxiao Lin Dong Xie Min Zhang Yan Zhang Jinjia Wei Huajie Xu Faliang Cheng Chuan Wu Shiguo Zhang | 2022 | Journal of Energy Chemistry2022，31，3： | 0 |
