Abstract
According to one embodiment, a reduction catalyst includes a current collector including a metal layer; and organic molecules including a quaternary nitrogen cation, which are bonded to the metal layer. The organic molecules are represented by any of the following general formulae I to V.
Claims13
A reduction catalyst comprising:
- a current collector comprising a metal layer comprising at least one metal selected from the group consisting of Au, Ag, Cu, Zn, Pt, Fe, Ti, Ni, Sn, In, and Bi;
- and
- organic molecules comprising a quaternary nitrogen cation, which are bonded to the metal layer and are represented by any of the following general formulae I to V:
- where, in the general formulae I to V, R1 is a primary, secondary, or tertiary amino group, R2 and R3 are identical to or different from each other and are each independently H or a primary, secondary, or tertiary amino group, p, q, r, and n are each independently an integer from 1 to 12, Y is a reactive functional group selected from the group consisting of a thiol group, a disulfide group, and a thiocyanate group, and X− represents a counter anion selected from the group consisting of a fluoride ion, a chloride ion, a bromide ion, an iodide ion, HCO3−, BF4−, PF6−, CF3COO−, CF3SO3−, NO3−, SCN−, N(CN)2−, C(CN)3−(CF3SO2)3C−, a bis(trifluoromethoxysulfonyl)imide anion, a bis(trifluoromethoxysulfonyl)imide anion, and a bis(perfluoroethylsulfonyl)imide anion.
