This paper illustrates the reaction of larch bark tannin extracts with sulfite and sodium hydroxide and the tests of its solution viscosity, mw - distribution and thin - layer chromatography
摘要通過對落葉松栲膠進行亞硫酸鹽和氫氧化鈉的改性，則定其溶液黏度，用不同溶劑進行分級和薄層色譜。Catalysts were prepared by impregnation reduction, thermal reduction, advanced thermal reduction and sol - gel methods from these metals. electrochemistry measurements, xrd, tem were used to test these catalysts. the results showed that these metals have some electrocatalysis activities towards hydrogen oxidation reaction
本文選擇了w 、 mo 、 co等金屬，採用浸漬還原法、熱還原法、改進的熱還原法以及溶膠凝膠法分別制備了這幾種金屬的碳載催化劑，對制備出的非貴金屬催化劑進行了電化學測試、 x -射線衍射（ x - raydiffraction ， xrd ） 、透射電子顯微鏡（ transmissionelectronmicroscopy ， tem ）等測試，研究結果表明:這些非貴金屬在硫酸體系中對氫氣的氧化反應均有一定的催化活性。
