Integration of metal-organic layers with quantum dots for artificial photosynthesis

Science China Chemistry 2024年第11期67卷 3712-3718页

作者： hong Yuan Min zhang Ji-hua Deng Tong-Bu lu Di-Chang Zhong Institute for New Energy Materials and Low Carbon Technologies School of Materials Science and Engineering School of Chemistry and Chemical Engineering Tianjin University of Technology

Metal-organic layers（MOLs）, a type of new-emerging two-dimensional ultrathin metal-organic framework materials with large surface areas and highly exposed active sites, have shown promising applications in photocatalytic CO2reduction. However, due to a lack of photosensitivity and photooxidation capability, photosensitizers and sacrificial reductants are usually necessary for MOLs-based photocatalytic CO2reduction systems. In this article, by integration of MOLs and quantum dots（QDs）, we constructed MOLs-based catalysts with multi-functions of photosensitivity, photoreduction and photooxidation, which thus can serve as photocatalysts for CO2reduction with H2O as an electron donor. Specifically, by an electrostatic self-assembly approach,nickel（Ⅱ）-based MOLs（Ni-MOLs） and CsPbBr3QDs have been assembled, constructing valid Ⅱ-Scheme Ni-MOLs/CsPbBr3heterojunctions with close Ni-MOLs/CsPbBr3heterointerface. Such a close heterointerface shortens the charge transfer distance,thus effectively boosting the charge separation and transfer. As a result, upon illumination by visible light(λ ≥ 400 nm,100 m W cm-2), the optimized photocatalyst shows high efficiency and stability in photochemical CO2reduction in the absence of any photosensitizers and sacrificial reductants. The CO yield reaches as high as 124 μmol g-1in 4 h, over 6 times higher than that achieved by CsPbBr3. Additionally, the selectivity reaches 100%. This work provides a new way to construct MOL-based catalysts for artificial photosynthesis.

Intrahepatic portal venous systems in adult patients with cavernous transformation of portal vein: Imaging features and a new classification

引用

Hepatobiliary & Pancreatic Diseases International 2024年第5期23卷 481-486页

作者： xin huang Qian lu Yue-Wei zhang Lin zhang Zhi-Zhong Ren Xiao-Wei Yang ying Liu Rui Tang Hepatopancreatobiliary Center Beijing Tsinghua Changgung HospitalSchool of Clinical MedicineTsinghua UniversityBeijing 102218China

Background: Cavernous transformation of the portal vein(CTPV) due to portal vein obstruction is a rare vascular anomaly defined as the formation of multiple collateral vessels in the hepatic hilum. This study aimed to investigate the imaging features of intrahepatic portal vein in adult patients with CTPV and establish the relationship between the manifestations of intrahepatic portal vein and the progression of CTPV. Methods: We retrospectively analyzed 14 CTPV patients in Beijing Tsinghua Changgung Hospital. All patients underwent both direct portal venography(DPV) and computed tomography angiography(CTA) to reveal the manifestations of the portal venous system. The vessels measured included the left portal vein(LPV), right portal vein(RPV), main portal vein(MPV) and the portal vein bifurcation(PVB). Results: Nine males and 5 females, with a median age of 40.5 years, were included in the study. No significant difference was found in the diameters of the LPV or RPV measured by DPV and CTA. The visualization in terms of LPV, RPV and PVB measured by DPV was higher than that by CTA. There was a significant association between LPV/RPV and PVB/MPV in term of visibility revealed with DPV( P = 0.01), while this association was not observed with CTA. According to the imaging features of the portal vein measured by DPV, CTPV was classified into three categories to facilitate the diagnosis and treatment. Conclusions: DPV was more accurate than CTA for revealing the course of the intrahepatic portal vein in patients with CTPV. The classification of CTPV, that originated from the imaging features of the portal vein revealed by DPV, may provide a new perspective for the diagnosis and treatment of CTPV.
