Kinetic experiments have shown that the argyrophil I reaction (the formation of metallic from ionic silver by reducing groups of the tissues) is a catalytic process. Topochemical considerations, and several reaction kinetic observations, suggest that the semi-conductor properties and the favourable chemical structure of certain sites (catalytic points) of the tissue structure play a fundamental role in the catalysis. The electrochemical half processes in the argyrophil I reaction (i.e., the transformation of tissue-bound reducing groups into their oxidized form and the reduction of silver ions into silver atoms) take place separately in space, while the electrons released in the former half reaction are transported by the semi-conduction bands of the tissue to the catalytic points where the metallic silver grains are formed.
动力学实验表明，嗜银I反应（通过组织的还原基团将离子银转化为金属银）是一个催化过程。拓扑化学方面的考虑以及一些反应动力学观察结果表明，组织结构某些位点（催化点）的半导体性质和有利的化学结构在催化过程中起着根本性作用。嗜银I反应中的电化学半反应（即组织结合的还原基团转化为其氧化形式以及银离子还原为银原子）在空间上是分开发生的，而在前一个半反应中释放的电子通过组织的半导体能带传输到形成金属银颗粒的催化点。
