Compositions with ability to oxidize and decompose organic matter

Abstract

A composition capable of oxidatively decomposing organic matter includes titanium dioxide particles and a metal element complex. The metal element complex includes a plurality of first silver particles and a plurality of second silver particles. The first silver particles are attached to the surface of the titanium dioxide particles and / or located inside the titanium dioxide particles, and the first silver particles account for a molar percentage of the metal element complex greater than or equal to 80 mol%. The second silver particles are located outside the titanium dioxide particles and are separated from the titanium dioxide particles, and the second silver particles account for a molar percentage of the metal element complex less than 20 mol%.
