Promoted reactants activation and charge separation leading to efficient photocatalytic activity on phosphate/potassium co-functionalized carbon nitride

引用

Chinese Chemical Letters 2019年第4期30卷 875-880页

Photocatalytic technology has been widely adopted to address the issue of air pollution. The separation of photogenerated carriers and the activation of reactants on catalyst surface are the main factors that affect the photocatalytic efficiency. Here, the phosphate/potassium(PO_4/K) cofunctionalized carbon nitride(labeled as PO_4-CN-K) was synthesized via a one-step in situ copyrolysis of thiourea and potassium phosphate. The unique electronic structure of PO_4-CN-K could significantly improve the performance of photocatalytic NO purification. The enhanced activity of PO_4-CN-K can be attributed to the promoted activation capacity for O_2, NO and H_2O on the catalyst surface,the decreased of carriers recombination, benefiting from the co-functionalization of phosphate groups on the surface of CN and the construction of K channels between CN layers. The photocatalytic NO conversion pathway is disclosed through time-dependent in situ FT-IR, indicating that PO_4-CN-K can efficiently convert NO molecules into harmless nitrate via the NO→NO+→nitrate/nitrite routes. The research provides a novel strategy to impel the development of photocatalytic technology for efficient air purification.

作者： YIN-YIN XIA PING ZHAN YANG WANG department of environment Hygiene Chongqing University of Medical Sciences Chongqing 400016 China

Objective To explore the effects of nonylphenol on brain gene expression profiles in F1 generation rats by microarray technique. Methods mRNA was extracted from the brain of 2-day old F1 generation male rats whose F0 female generation was either exposed to nonylphenol or free from nonylphenol exposure, and then it was reversely transcribed to cDNA labeled with cy5 and cy3 fluorescence. Subsequently, cDNA probes were hybridized to two BiostarR-40S cDNA gene chips and fluorescent signals of cy5 and cy3 were scanned and analyzed. Results Two genes were differentially down-regulated. Conclusion Nonylphenol may disturb the neuroendocrine function of male rats when administered perinatally.

Theoretical Study on the Structures and Properties of Phenobarbital Imprinted Polymers

引用

Chinese Journal of Structural Chemistry 2014年第10期33卷 1421-1430页

作者：苏婷婷刘俊渤唐珊珊常海波靳瑞发 College of Resources and environment Jilin Agricultural University department of Chemistry Chifeng University

Recently, the investigation of novel molecularly imprinted polymers（MIPs） has attracted a lot of interest and becomes a fascinating field. The phenobarbital（PHN） was taken as an imprinted molecule and the 2-vinyl-4,6-diamino-1,3,5-triazine（VDAT） was considered as a functional monomer in this study. The geometry optimization, natural bond orbital（NBO） charge, and molecular electrostatic potential（MEP） of PHN and VDAT were studied at the M062 X level belonging to one of the hybrid density functional theories. Furthermore, we discussed the bonding conditions of PHN molecular imprinted polymers（PHN-MIPs） via the hydrogen bond length and atoms in molecules（AIM） theory. The rebinding property of PHN-MIPs was also researched. The results of MEP and NBO charge analysis were coincident. The stability property was excellent when the ratio of PHN and VDAT was 1：4. Except the classic hydrogen bonds, non-classical hydrogen bonds also existed in the imprinted polymers. By simulating the rebinding energies between the pentobarbital（PNT）, barbital（BAR）, and PHN-MIPs after the elution of PHN, the rebinding property of PHN-MIPs to PHN was excellent when PNT and BAR existed all at once. This research can provide theoretical reference for the synthesis and characterization of novel PHN-MIPs.

Microstructural developments and precipitate transformation during transient liquid-phase bonding of a duplex stainless steel

引用

Journal of Central South University 2013年第1期20卷 15-23页

作者：袁新建 KANG Chung-Yun College of materials Science and Engineering Chongqing University department of materials Science and Engineering Pusan National University

Effect of holding time on microstructural developments and transformation of precipitates formed at the interface during transient liquid-phase bonding of a duplex stainless steel using a Ni-based amorphous insert alloy was studied. The experimental results reveal that the microstructure of the adjacent base metal varies clearly as a function of holding time. The migration of Cr and Ni elements and the → transformation seem to play relevant roles in this microstructure evolution. The scanning electron microscopy (SEM) and electron prob X-ray microanalysis (EPMA) results indicate the transformation of BN→BN and (N, Mo) boride→BN at the interface with the holding time of 60-1 800 s. N content changes with holding time increasing at locations at the interface might be a controlling factor contributing to this transformation.

A new protocol for the NiC12-catalyzed cross-electrophile coupling of aryl bromides with pyrimidin-2-yl tosyl- ates to give the corresponding C2-arylation pyrimidine derivatives has been developed. This study provides an improvement over previous methods by using pyrimidin-2-yl tosylates instead of halides as coupling partners that are stable and easily available.
