Our group has developed a series of molecular electrocatalysts for hydrogen generation based on triazenido–metal complexes (cobalt, copper, etc.). In this paper, we first present the electrocatalytic performance of a new dinuclear silver complex, [Ag2(L)2], formed by the reaction of the triazenido ligand 1‐[(2‐carboxymethyl)benzene]‐3‐[(2‐methoxy)benzene]triazene (HL) with AgNO3. At room temperature, the silver complex shows photoluminescence at 653 nm. The electrocatalytic systems based on this silver complex can afford 106.57 and 1536.36 moles of hydrogen per mole of catalyst per hour from acetic acid at an overpotential (OP) of 991.6 mV and from a neutral aqueous buffer (pH = 7.0) at an OP of 837.6 mV, respectively. Electrochemical investigations show that both silver ion and triazenido ligand play a role in determining the catalytic activities of the electrocatalytic system. 相似文献

In this study, the Cu-doped Ce?Mn/ATP denitration catalyst was prepared by impregnation method and heterogeneous precipitation method and its denitrification performance was tested. It was found that the denitrification effect was obviously improved after Cu doping. And the denitration effect of the catalyst prepared by the heterogeneous precipitation method was better and the denitrification rate was above 98%. Under this method, n(Cu: Mn) = 1 had the best denitration effect, with a maximum of 99.76%. The prepared catalysts were characterized by means of XRD, XPS, BET, and SEM. The results showed that CuMn2O4 and CuO appeared in the Cu doped catalysts. Moreover, the doping of Cu enriched the pore structure and surface morphology of the catalyst, so that the catalyst showed good denitrification performance.
