A series of amorphous silver silicates with different compositions were synthesized for the first time by one‐step co‐precipitation. Silicate ions were found to have important role on determining visible light absorption and photocatalytic activities of amorphous silver silicates, and the sample with Ag/Si ratio of 3.20 exhibits optimal photocatalytic activity.
