摘要： A composition of matter suitable for the generation of hydrogen from water is described, the positively charged cation of the composition having the general formula [(PY5 W2)MO]2+, wherein PY5W2 is (NC5XYZ)(NC5H4)C2W2, M is a transition metal, and W, X, Y, and Z can be H, R, a halide, CF3, or SiR3, where R can be an alkyl or aryl group. The two accompanying counter anions, in one embodiment, can be selected from the following Cl', I', PF6", and CF3SO3". In embodiments of the invention, water, such as tap water containing electrolyte or straight sea water can be subject to an electric potential of between 1.0 V and 1.4 V relative to the standard hydrogen electrode, which at pH 7 corresponds to an overpotential of 0.6 to 1.0 V, with the result being, among other things, the generation of hydrogen with an optimal turnover frequency of ca. 1.5 million mol H2/mol catalyst per h.
摘要翻译：描述了适用于由水产生氢的物质组合物，具有通式[（PY5W2）MO] 2+的组合物的带正电的阳离子，其中PY5W2是（NC5XYZ）（NC5H4）C2W2，M是过渡金属，W，X，Y和Z可以是H，R，卤化物，CF 3或SiR 3，其中R可以是烷基或芳基。在一个实施方案中，两个伴随的抗衡阴离子可以选自以下Cl'，I'，PF6“和CF3SO3”。在本发明的实施例中，相对于标准氢电极，诸如包含电解质或直海水的自来水可以经受1.0V至1.4V的电势，其在pH7对应于0.6至 1.0 V，其结果是，除了别的以外，氢的产生具有最佳的周转频率ca。每小时150万摩尔H 2 / mol催化剂。
