Document Type and Number:
Japanese Patent JP5115998
Kind Code:
B2
Abstract:
The present invention provides the catalyst precursor that has excellent safety and stability, has high stable activity retention rate, can be recycled, increases yield resulted from a reaction, and is easily processed into various forms. The catalyst precursor comprises a structure in which the entire structure is composed of gold or a gold-based alloy and the surface of the structure is modified with elemental sulfur, or at least the surface of the structure is composed of gold or a gold-based alloy and the surface of the structure is modified with elemental sulfur, and a catalytic metal compound supported on the structure, wherein the catalyst precursor has peaks derived from the catalytic metal compound and also sulfur as analyzed by photoelectron spectroscopy, and wherein the peak derived from sulfur is of the sulfur 1s orbital observed within a range of 2470 eV ± 2 eV in terms of the peak top position.
