WebOne approach is a two-step process where a strong reductant, mostly NaBH 4, is used to initiate the reaction, forming small particles. These particles in a second step are enlarged with a weaker reductant (Sharma et al., 2009). Another approach involves using Tollens or modified Tollens methods. These imply the stabilization of the silver ...
