More and more serious energy crisis and greenhouse effect force people to find the appropriate solutions. Photocatalytic reduction of CO 2 into hydrocarbon fuels is one of the most potential strategies. In this paper, novel one-dimensional (1D) carbon [email protected] 2 core-shell nanocomposites have been prepared via electrospun synthesis of carbon nanofibers core followed by in situ growth of TiO 2 shell, which exhibit a 2.3-fold higher photocatalytic activity than the pure TiO 2 . The increase of catalytic performance attributed to higher specific surface areas of carbon [email protected] 2 core-shell nanocomposites for providing more surface-active sites. Moreover, the black carbon nanofibers promote light absorption, and the light energy can be converted into heat energy that can speed up the diffusion of reactants and products. Most importantly, the carbon nanofibers with good electrical conductivity can speed up the separation of the photo-induced electron and hole pairs in photocatalyst. This work provides a good synthesis of 1D core-shell heterostructure, and proves that the carbon nanofibers can be an ideal cocatalyst for enhancing photocatalytic CO 2 reduction performance of TiO 2 .

Spark plasma sintering（SPS） was used to weld the ceramics,eg,Cr3C2 and metal,Ni in this *** is found that the SPS can weld the Cr3C2 and Ni plates at lower temperatures and shorter holding time comparing with that of hot-pressing（HP）.The binding strength was 113 MPa when the temperature was 1000 ℃ by SPS,compared with 10 MPa by HP at the same *** remarkably enhances the atom diffusion in *** analysis at different welding temperatures and holding times of SPS or HP shows that the local temperature gradient,different from the past effects of by-passing current,is the dominative mechanism of the SPS welding.

Mullite whiskers were prepared via non-hydrolytic sol-gel process combined with molybdate molten salt using tetraethoxysilane and anhydrous aluminum chloride as precussor, anhydrous ether as oxygen donor, molybdate as molten salt. The effects of heat treatment temperature, molten salt amount, holding time on synthesis and morphology of mullite whiskers were investigated by X-ray diffraction (XRD) and field emission scanning electron microscopy (FE-SEM). The results show that the mullite whiskers appeared at the lowest temperature of 800℃, and optimized mullite whiskers could be prepared at 900℃ for 8 h with the mass ratio of xerogel and molybdate as 1:2, the diameter of the whiskers was in the range of 0.15-0.22 μm with the aspect ratio of more than 40. © 2016 Trans Tech Publications, Switzerland.

Phosphorene Co‐catalyst Advancing Highly Efficient Visible‐Light Photocatalytic Hydrogen Production

引用

Angewandte Chemie 2017年第35期129卷

作者： Jingrun Ran Bicheng Zhu Shi‐Zhang Qiao School of Chemical Engineering University of Adelaide Adelaide SA 5005 Australia State Key Laboratory of Advanced Technology for Material Synthesis and Processing Wuhan University of Technology 122 Luoshi Road Wuhan 430070 P.R. China

Transitional metals are widely used as co‐catalysts boosting photocatalytic H 2 production. However, metal‐based co‐catalysts suffer from high cost, limited abundance and detrimental environment impact. To date, metal‐free co‐catalyst is rarely reported. Here we for the first time utilized density functional calculations to guide the application of phosphorene as a high‐efficiency metal‐free co‐catalyst for CdS, Zn 0.8 Cd 0.2 S or ZnS. Particularly, phosphorene modified CdS shows a high apparent quantum yield of 34.7 % at 420 nm. This outstanding activity arises from the strong electronic coupling between phosphorene and CdS, as well as the favorable band structure, high charge mobility and massive active sites of phosphorene, supported by computations and advanced characterizations, for example, synchrotron‐based X‐ray absorption near edge spectroscopy. This work brings new opportunities to prepare highly‐active, cheap and green photocatalysts.

The majority of the thermal energy released in an automotive internal combustion cycle is exhausted as waste heat through the tail pipe. This paper describes an automobile exhaust thermoelectric generator (AETEG), designed to recycle automobile waste heat. A model of the output characteristics of each thermoelectric device was established by testing their open circuit voltage and internal resistance, and combining the output characteristics. To better describe the relationship, the physical model was transformed into a topological model. The connection matrix was used to describe the relationship between any two thermoelectric devices in the topological structure. Different topological structures produced different power outputs; their output power was maximised by using an iterative algorithm to optimize the series-parallel electrical topology structure. The experimental results have shown that the output power of the optimal topology structure increases by 18.18% and 29.35% versus that of a pure in-series or parallel topology, respectively, and by 10.08% versus a manually defined structure (based on user experience). The thermoelectric conversion device increased energy efficiency by 40% when compared with a traditional car.

中国化学会第九届全国无机化学学术会议

Crystalline microporous zeolites are one of the most useful catalysts in industrial processes such as oil refining and organic synthesis owing to their strong catalytic performance, high thermal and hydrothermal stabilities, and well-defined micropores with excellent shape-selectivity in catalysis. However, one disadvantage of these zeolitic catalysts is that their pores are too small to be accessed by bulky reactants, thus hindering their use in the fine chemical and petroleum processing industries. To overcome such drawbacks, we have synthesized hierarchically ordered micro-meso-macroporous solid-acid catalysts via a chemically crystallization process in an improved hydrothermal system. Zeolites, including Silicalite-1, ZSM-5, Beta and TS-1, with hierarchically ordered micro-meso-macroporous structure have been synthesized. It is expected that these hierarchical zeolite materials will exhibit superior catalytic performance owing to the improved mass-transfer properties.
