There is a relatively low efficiency of Fe(Ⅲ)/Fe(Ⅱ) conversion cycle and H2 O2 decomposition(<30%) in conventional Fenton process,which further results in a low production efficiency of ·OH and seriously restricts the application of ***,we report that the commercial MoO2 can be used as the cocatalyst in Fenton process to dramatically accelerate the oxidation of Lissamine rhodamine B(L-RhB),where the efficiency of Fe(Ⅲ)/Fe(Ⅱ) cycling is greatly enhanced in the Fenton reaction *** the L-RhB solution could be degraded nearly 100% in 1 min in the MoO2 cocatalytic Fenton system under the optimal reaction condition,which is apparently better than that of the conventional Fenton system(~50%).Different from the conventional Fenton reaction where the ’OH plays an important role in the oxidation process,it shows that 1 O2 contributes most in the MoO2 cocatalytic Fenton ***,it is found that the exposed Mo^4+ active sites on the surface of MoO2 powders can greatly promote the rate-limiting step of Fe^3+/Fe^2+ cycle conversion,thus minimizing the dosage of H2 O2(0.400 mmol/L) and Fe^2+(0.105 mmol/L).Interestingly,the MoO2 cocatalytic Fenton system also exhibits a good ability for reducing Cr(Ⅵ) ions,where the reduction ability for Cr(Ⅵ) reaches almost 100% within 2 *** short,this work shows a new discovery for M002 cocatalytic advanced oxidation processes(AOPs),which devotes a lot to the practical water remediation application.

Chinese Chemical Letters 2019年第4期30卷 853-862页

作者： chencheng dong Jiahui Ji Zhe Yang Yifei Xiao Mingyang Xing Jinlong Zhang Key Laboratory for Advanced Materials and Institute of Fine Chemicals School of Chemistry & Molecular Engineering East China University of Science and Technology Department of Civil Engineering The University of Hong Kong

With the development of the human economy and green chemistry, people pay much more attention to environmental safety. Correspondingly, mesoporous TiO_2 and its correlated photocatalysts are able to help people seek for better life. In this review, first of all, we briefly introduce the preparations and applications of mesoporous TiO_2-SiO_2 materials, which exhibit excellent performance in pollutants decomposition and H_2 evolution in photocatalysis. Then, we review the mesoporous composites of TiSiO_2 materials, which are ideal materials used in the photoreduction of air pollutants such as CO_2, NO and NO_2. It is powerfully evident from the literature surveys that these TiO_2 based mesoporous photocatalysts possess a large potential in environment and energy development.

目的探讨胃癌耐药复发相关基因ABCC4在胃癌耐药复发中的分子机制。方法采用免疫组织化学、Western blot、RT-PCR、流式细胞检测胃癌组织及胃癌耐药细胞中ABCC4的表达情况,利用RNA干扰技术下调ABCC4基因在胃癌耐药细胞中的表达水平。结果 ABCC4基因在多种胃癌细胞中高表达,尤其是在胃癌耐药细胞中表达增加更为显著,但在正常胃黏膜细胞中极低表达或表达缺失。RNA干扰下调ABCC4基因可导致胃癌耐药细胞发生凋亡,并且细胞周期被阻滞在G1期以内。5-Fu可以显著抑制ABCC4沉默后肿瘤细胞增殖,同时,也能明显抑制ABCC4沉默后裸鼠体内肿瘤生长。结论 ABCC4基因过度表达于胃癌耐药细胞中,下调ABCC4基因表达可抑制胃癌多药耐药细胞增殖,并且可增强其对化疗药物的敏感度。

Metal-organic framework derived CoSe2 nanoparticles anchored on carbon fibers as bifunctional electrocatalysts for efficient overall water splitting

引用

Nano Research 2016年第8期9卷 2234-2243页

作者： chencheng Sun Qiuchun dong Jun Yang Ziyang Dai Jianjian Lin Peng Chen Wei Huang Xiaochen dong Key Laboratory of Flexible Electronics (KLOFE) & Institute of Advanced Materials (IAM) Jiangsu National Synergetic Innovation Center for Advanced Materials (SICAM) Nanjing Tech University (NanfingTech) 30 South Puzhu Road Nanjing 211816 China School of Chemical and Biomedical Engineering Nanyang Technological University 62 Nanyang Drive 637459 Singapore Singapore

The development of efficient, low-cost, for water splitting, particularly those stable, non-noble-metal electrocatalysts that can catalyze both the hydrogen evolution reaction （HER） at the cathode and oxygen evolution reaction （OER） at the anode, is a challenge. We have developed a facile method for synthesizing CoSe2 nanoparticles uniformly anchored on carbon fiber paper （CoSe2/CF） via pyrolysis and selenization of in situ grown zeolitic imidazolate framework-67 （ZIF-67）. CoSe2/CF shows high and stable catalytic activity in both the HER and OER in alkaline solution. At a low cell potential, i.e., 1.63 V, a water electrolyzer equipped with two CoSe2/CF electrodes gave a water-splitting current of 10 ***-2. At a current of 20 mA-cm-2, it can operate without degradation for 30 h. This study not only offers a cost-effective solution for water splitting but also provides a new strategy for developing various catalytic nanostructures by changing the metal-organic framework precursors.
