New Membrane Architecture with High Performance: ZIF-8 Membrane Supported on Vertically Aligned ZnO Nanorods for Gas Permeation and Separation
Xiongfu Zhang,Yaguang Liu,Li Shaohui,Lingyin Kong,Haiou Liu,Yanshuo Li,Wei Han,King Lun Yeung,Weidong Zhu,Weishen Yang,Jieshan Qiu +10 more
TL;DR: In this article, a new ZIF-8 membrane architecture with high performance supported on vertically aligned ZnO nanorods was successfully prepared, which provided multiple anchorages for the ZIF8 membrane that are both strong and flexible.
Journal ArticleDOI
Dissolution and Microstructural Transformation of ZnO Nanoparticles under the Influence of Phosphate
TL;DR: This is the first study in which the detailed process of phosphate-induced speciation and microstructural transformation of ZnO NPs has been analyzed and may play an important role in the behaviors, fate, and toxicity of many other metal-based nanomaterials in the environment.
Journal ArticleDOI
A simple and scalable method for preparing low-defect ZIF-8 tubular membranes
Xiongfu Zhang,Yaguang Liu,Lingyin Kong,Haiou Liu,Jieshan Qiu,Wei Han,Lu-Tao Weng,King Lun Yeung,Weidong Zhu +8 more
TL;DR: Substrate modification by an ultrathin ZnO layer followed by surface activation promotes homogeneous surface nucleation and the growth of a low-defect ZIF-8 tubular membrane that exhibits superb gas permeation and permselectivity as discussed by the authors.
Journal ArticleDOI
Operando Investigation of Toluene Oxidation over 1D Pt@CeO2 Derived from Pt Cluster-Containing MOF.
Qingyue Wang,Qingyue Wang,Yuxin Li,Ana Serrano-Lotina,Wei Han,Raquel Portela,Ruixuan Wang,Miguel A. Bañares,King Lun Yeung +8 more
TL;DR: The Pt-CeO2 interface generates reduced ceria sites forming nearby adsorbed peroxide at low temperature that oxidize toluene into benzoate species by a Langmuir-Hinshelwood mechanism as the reaction temperature increases, and the role of lattice oxygen becomes important.
Journal ArticleDOI
Catalytic behavior of hydrothermally synthesized La0.5Sr0.5MnO3 single-crystal cubes in the oxidation of CO and CH4
TL;DR: In this article, single-crystal cubes and nanoparticles were synthesized by hydrothermal and citrate routes, respectively, and their catalytic properties for low-temperature co oxidation and high temperature ch4 combustion were evaluated.
