FAU-type zeolite membranes were prepared by an in situ aging-microwave synthesis (AM) method using a clear solution with the molar composition of 70Na(2)O: 1Al(2)O(3): 20SiO(2): 2000H(2)O. After two-stage AM synthesis, a defect-free FAU zeolite layer consisted of uniform zeolite crystals was formed on the support surface. The Si/Al ratio was ca. 1.5. The single-gas permeation and single-liquid vapor permeation properties of the as-synthesized zeolite membranes were investigated. The permselectivity of H-2 and N-2 was as high as 4.25 for FAU-type zeolite membranes. Pervaporation measurements were carried out for the dehydration of ethanol and isopropanol aqueous solutions. FAU-type zeolite membranes displayed relatively high permeation flux and water-selectivity. (C) 2008 Elsevier B.V. All rights reserved.

Efficient removal of acetaldehyde from ethanol by template-free synthesized mesoporous SiO2-based solid acid catalyst with high surface silicon exposure

Zhenguo Lyu, Hu Wang, Yicheng Ye, Zhuwei Zhu, Guoying Weng, Dingbing He, Fan Li, Yanshuo Li, Chen Chen

Summary: A mesoporous silica-based solid acid with high surface area, large pore size, and moderate acid amount was synthesized through a one-step reverse-phase microemulsion method. The acid catalyst introduced 3-sulfopropyl as the acidic sites, resulting in a high surface silicon exposure and plenty of active groups. A novel strategy of waste to value was used to remove acetaldehyde from ethanol, converting it to a safer chemical of acetal with a pleasant odor. The remaining acetaldehyde could be controlled to a very low and safer level with a wide range of initial concentration.

Yanwei Sun, Jiahui Yan, Yunlei Gao, Taotao Ji, Sixing Chen, Chen Wang, Peng Lu, Yanshuo Li, Yi Liu

Summary: In this study, a novel technique was developed to fabricate Zr-MOF membranes with excellent performance by concurrently regulating crystallographic orientation and thickness. Uniform triangular-shaped UiO-66 nanosheet seeds with a thickness of 40 nm were prepared using an anisotropic etching strategy. Through confined counter-diffusion-assisted epitaxial growth, highly (111)-oriented UiO-66 membranes with a thickness of 165 nm were achieved. These membranes exhibited unprecedented CO2 permeance (2070 GPU) and high CO2/N-2 selectivity (35.4), surpassing the performance limits of state-of-the-art polycrystalline MOF membranes. Additionally, highly (111)-oriented NH2-UiO-66 membranes with a thickness of 180 nm were prepared, showing superb H-2/CO2 separation performance with H-2 permeance of 1230 GPU and H-2/CO2 selectivity of 41.3.

Higher acidity promoted photodegradation of fluoroquinolone antibiotics under visible light by strong interaction with a niobium oxide based zeolitic octahedral metal oxide

Qiangqiang Tong, Chuntian Qiu, Guijin Zheng, Qianqian Zhu, Shiman Zhou, Yukang Wang, Li Shi, Huifei Wang, Dingbing He, Masahiro Sadakane, Yanshuo Li, Zhenxin Zhang

Summary: A zeolitic octahedral metal oxide based on niobate (ZOMO-NbOx) with high acidity was synthesized and used as an efficient catalyst for the degradation of fluoroquinolone antibiotics under visible light. The presence of higher acidity promoted the adsorption of ciprofloxacin (CIP) on ZOMO-NbOx, expanding its light-absorbing range from UV to visible light through ligand to metal charge transfer. ZOMO-NbOx exhibited significantly higher catalytic activity compared to commercial Nb2O5, with a TOF value 53 times higher, and remained stable after multiple reuses. It also demonstrated good resistance to inorganic ions and humic acids, and effectively degraded CIP in various natural freshwater bodies. The intermediate products were identified and degradation pathways were proposed.

Efficient and selective photocatalytic CO2 reduction over Ga single atom decorated quantum dots under visible light

Li Shi, Yingkui Yan, Ye Wang, Tingting Bo, Wei Zhou, Xiaohui Ren, Yanshuo Li

Summary: Exploring unique single atoms as catalytic sites is important but challenging for improving photocatalytic CO2 reduction. Gallium (Ga) single atoms decorated on CdSe quantum dots (QDs) effectively enhance the CO evolution rate to 16.1 mu mol h(-1) with a selectivity of 90.4% over 30 hours, surpassing bare CdSe QDs. The mechanism involves efficient separation of electron-hole pairs and enhanced CO2 adsorption ability due to Ga single atoms, as well as effective electron trapping and suppression of H-2 evolution by surface Ga catalytic sites.
