Improving Barium Ions Adsorption on Two-Dimensional Titanium Carbide by Surface Modification

30-May-2018 | Wanjun Mu; shenzhen du; qianhong yu; Xingliang Li; Hongyuan Wei; Yuchuan Yang, Dalton Transactions, 2018

Recently, 2D-MXene materials have attracted much attention. However, their low adsorption capacities for metal ions have limited their application in nuclear wastewater disposal. Here, we describe unprecedentedly large adsorption by Ti3C2Tx for removal of radionuclides by a simple and efficient ...

Hydride ion (H−) transport behavior in barium hydride under high pressure

27-May-2018 | Xin Zhang; Xiaoli Wang; Qinglin Wang; Xinjun Ma; Chunming Liu; Peifang Li; Cailong Liu; Yonghao Han; Yanzhang Ma; Ch ..., Physical Chemistry Chemical Physics, 2018

Hydride ions (H−) have an appropriate size for fast transport, which makes the conduction of H− attractive. In this work, the H− transport properties of BaH2 have been investigated under pressure using in situ impedance spectroscopy measurements up to 11.2 GPa and density functional theoretical ...

Morphology control of BaCO3 by template and polymer–inorganic precursor

16-Jan-2018 | Yong Zhang; Beibei Xie; Renjie Zhang, New Journal of Chemistry, 2018

Barium carbonate (BaCO3) within the controllable morphology of nanorods (NRs) was prepared by employing pore channels of a polycarbonate (PC) membrane as the template, combining with poly(sodium 4-styrene-sulfonate) (PSS). To further lower the crystallization process, (PSS/PAH)1.5 polyelectrolyte ...
