It was discovered that when ethyl nitrite was introduced to the surface of catalyst, Pd ethoxyl compound was formed and simultaneously the active site Pd was transferred to the surface of catalysts with the change from Pd〓 to Pd〓. Then lined-adsorbed CO inserted into Pd alkoxyl compound to form the carboethoxypalladium complex.

研究结果表明，在CO偶联反应过程中，亚硝酸乙酯在催化剂上吸附，生成钯乙氧基络合物，同时将催化剂表面上的活性中心氧化，由Pd〓→Pd〓，并向催化剂表面上迁移。

The Pd-Cu/C catalysts were shown to have the face centered cubic crystal structure. This could indicate that the addition of Cu shortened the Pd-Pd distances in the crystal lattice, and therefore –HO(subscript 2ads) and O-O could be better adsorbed on the surface of the catalyst. When NaBH4 was used as the reducing agent, and the atomic ratio of Pd to Cu was 3:1, the resulting catalysts had an average particle size of 3. 4nm and showed the best catalytic performance. The electrochemical active surface are a of Pd3Cu/C was 38.9m^2/gPd and the oxidation reduction reaction activity of the Pd3Cu/C catalyst was much higher than that of the Pd/C catalyst. The electrochemical activity of the Pd3Cu/C catalyst was comparable to that of a commercial Pt/C catalyst.

结果表明：催化剂中Pd与Cu的物质的量之比与预设值相近，Pd和Cu基本被全部还原；Pd-Cu/C催化剂为面心立方结构，元素铜的加入使催化剂的Pd-Pd间距缩小，从而HO(下标 2 ads)和OO键能更好地吸附在催化剂金属表面；当采用NaBH4为还原剂，Pd与Cu物质的量比为3：1时，催化剂(Pd3Cu/C)的平均粒径为3.4 nm，催化剂的催化性能最好，电化学活性表面积EAS达到38.9平方公尺/gPd，电化学性能较Pd/C催化剂有很大提高，接近Pt/C商用催化剂。

Due to its linear chain structure, polyacrylamide, combined with DDA, tends to form the high molecular collector with more surface activities. In addition, with the high molecular weight, polyacrylamides (with the exception of hydroxamic acid polyacrylamide) can strongly flocculate kaolinite, which can increase the adsorptive density of collector and activate the kaolinite flotation.
