The emergence of hybrid organic-inorganic metal halide perovskite solar cells （PSCs） causes a break through in the solar technology recently due to its fabrication processes. The dramatic enhancenlent in in 2009 to the recent certified record PCE of 22.7% superior optoelectronic properties and the low-cost power conversion efficiency （PCE） of PSCs flom 3.8% ndicates huge potential of PSCs for future high efficiency and large scale photovoltaic manufacturing. The electron selective layer （ESL） plays an important role in electron extraction and hole blocking function in PSCs, and there have been great interest in developing efficient ESL materials. Recently, tin oxide （SnO2） as an ESL has attracted significant research attentions owing to its low temperature preparation processes as well as yielding high PCE and good stability of PSCs. In this perspective article, we focus on the development progress of SnO2 as an ESL m PSCs, and discuss the strategies for preparing SnO2 to achieve PSCs with high efficiency, less hysteresis and good device stability.

Rare Metals 2003年第3期22卷 226-229页

作者： ZHANG Xiangjun, HUANG Songtao, WU Guoliang, LU Shigang, and CAI ZhenpingGeneral Research Institute for Non-ferrous Metals, Beijing 100088, China General Research Institute for Non-ferrous Metals 北京 100088

A SnO-graphite composite material, which can deliver high capacities and good cycling stability compared with unsupported SnO, was described. This material prepared via chemical co-precipitation reaction in the presence of graphite consists of high dispersion of SnO with a size of about several hundred nanometers in the graphite. The phase structure was analyzed by X-ray diffraction (XRD). The morphology and the element distribution were examined by scanning electron microscopy (SEM) equipped with energy spectrum. The results show that the SnO-graphite composites produced by slowly hydrolysis have higher rechargeable capacities than pure graphite and better cycling performance than SnO.

tin oxide（SnO2） hollow microspheres with narrow size distribution were prepared by a facile one-pot microwave-assisted spray pyrolysis method. The effect of temperature on microstructural and optical properties was investigated by X-ray diffraction（XRD）, scanning electron microscope（SEM）, high resolution transmission electron microscope（HRTEM）, and UV-Vis spectrophotometer（UV-Vis）, *** SnO2 particles obtained at and above 700？C are tetragonal rutile structure with high purity and smooth surface morphology, which consist of well-interconnected SnO2 nanocrystallines and the shell thickness was about 26 nm. UV-Vis absorption values were quite low in visible light region and high in ultraviolet region, indicating the possible utilization for optical purpose of the as-prepared SnO2. The band gaps were 3.88 and 4.07 e V for SnO2 synthesized at 700 and 800？C, respectively. As compared to traditional electrical heating or flame modes, microwave heating introduced here demonstrates a highefficiency, environmentally benign, and time-and energy-saving technology to synthesize advanced powders.

Nitrogen doped tin oxide nanostructured catalysts for selective electrochemical reduction of carbon dioxide to formate

Journal of Energy Chemistry 2017年第5期26卷 825-829页

作者： Qiankun Li Zhuo Wang Miao Zhang Pengfei Hou Peng Kang Technical Institute of Physics and Chemistry Chinese Academy of Sciences University of Chinese Academy of Sciences

tin/tin oxide materials are key electrocatalysts for selective conversion of CO;to formate/formic *** we report a tin oxide material with nitrogen doping by using ammonia treatment at elevated temperature. The N doped material demonstrated enhanced electrocatalytic CO;reduction activity, showing high Faradaic efficiency（90%） for formate at -0.65 V vs. RHE with partial current density of 4 mA/cm;.The catalysis was contributed to increased electron negativity of N atom compared to O atom. Additionally, the N-doped catalyst demonstrates sulfur tolerance with retained formate selectivity. The analysis after electrolysis shows that the catalyst structure partially converts to metallic Sn, and thus the combined Sn/N-SnO;is the key for the active CO;catalysis.

作者： Ramanathan SARASWATHY Department of Physics Velammal Institute of Technology Panchetti Thiruvallur-601204 India

Synthesis of nanostructured Ru-doped SnO2 was successfully carried out using the reverse microemulsion method. The phase purity and the crystallite size were analyzed by XRD. The surface morphology and the microstructure of synthesized nanoparticles were analyzed by SEM and TEM. The vibration mode of nanoparticles was investigated using FTIR and Raman studies. The electrochemical behavior of the Ru- doped SnO2 electrode was evaluated in a 0.1 mol/L Na2SO4 solution using cyclic voltammetry. The 5% Ru-doped SnO2 electrode exhibited a high specific capacitance of 535.6 Fig at a scan rate 20 mV/s, possessing good conductivity as well as the electro- cycling stability. The Ru-doped SnO2 composite shows excellent electrochemical properties, suggesting that this composite is a promising material for supercapacitors.

The Pr2O3 doped SnO2 dense ceramic was prepared by co-precipitation method and further sintering. Through the micrograph of the cross-sectional microstructure of the electrodes, the sintering process was analyzed and discussed. Results showed that the solid phase sintering was exhibited at the early stage;when sintering was kept going on, the instant liquid phase could be emerged due to the rich dopants in the grain boundary. Finally, there would be much secondary phase existe as the concentration of dopants reached to a certain value.
