    Selective catalytic reduction of NOx by H2 using proton conductors as catalyst supports
    摘要:
    The selective catalytic reduction (SCR) of NO, by H-2 was studied using proton-conducting Sn0.9In0.1 P2O7 as a catalyst support at 50-350 degrees C. When a mixture of 800 ppm NO, 1400-8400 ppm H2, and 5% 02 in Ar was introduced to the Pt/C working electrode, NO, was reduced to N-2 with N2 selectivity values >80%. The reaction mechanism was shown to be based on a mixed potential at the Pt/C working electrode. This mechanism was also applicable to a Sn0.9In0.1 P2O7-supported Pt catalyst. H2 SCR over the Pt/Sn0.9In0.1 P2O7 catalyst was characterized by a wide operating temperature window (50-350 degrees C) and remarkable N2 selectivity values (>80%). Catalyst performance could be further improved by the addition of Rh to Pt, in which NO, conversion was a maximum 1.4 times higher than that over the Pt/Sn0.9In0.1 P2O7 catalyst and N-2 selectivity was increased to >89% at all temperatures tested.

Undoped SnP 2 O 7 showed overall conductivities greater than 10 -2 S cm -1 in the temperature range of 75-300°C. The proton transport numbers of this material at 250°C under various conditions were estimated, based on the ratio of the electromotive force of the galvanic cells to the theoretical

    Tin oxide and amorphous tin borophosphates have recently received significant attention as possible new negative electrode materials for lithium batteries. In this study, we have carefully investigated a number of different well-characterised tin phosphates as electrodes in Li-ion cells, in order to better understand the mode of operation of these materials and how their performance is related to structure
    氧化和无定形锡酸锡最近作为电池的新型负极材料受到了广泛的关注。在这项研究中,我们仔细研究了许多不同特性的磷酸作为离子电池中的电极,以便更好地了解这些材料的工作方式以及它们的性能与结构和组成之间的关系。研究的材料为立方晶和层状SnP 2 O 7,LiSn 2(PO 4)3,Sn 2 P 2 O 7和Sn 3(PO 4)2以及非晶Sn2 BPO 6。立方SnP 2 O 7表现出最好的性能,当相对Li m在0.02和1.2 V之间循环时,其可逆比充电容量> 360 mA hg -1,并且在50个循环中的容量保持率为96%。与研究中的三种Sn(II)材料相比,三种Sn(IV)材料显示出较低的初始可逆容量,但具有更好的容量保持能力。它们较高比例的惰性基质材料可以部分解释这一点。但是,立方SnP 2 O 7循环性能明显好于其层状多晶型物,这表明起始材料的结构也非常重要。从结果中得出的另一个
