Abstract
This invention provides a fine particle composite comprising fine particles of a sulfide or sulfide complex comprising at least one element selected from the group consisting of molybdenum (Mo), rhodium (Rh), ruthenium (Ru), and rhenium (Re) and conductive fine particles via a step of preparing a solvent mixture from a compound containing conductive carbon powder, at least one compound containing an element selected from among molybdenum (Mo), rhodium (Rh), ruthenium (R), and rhenium (Re), and sulfur (S) and a step of conducting a hydrothermal or solvothermal reaction at a pressure and temperature that convert the solvent mixture into a supercritical or subcritical water or solvent.
