Sulfidation
Notably, the direct sulfidation of AgNPs occurs in the absence of oxygen, provided a high concentration of hydrogen sulfide is present. However, this sulfidation process depends on the pH of the parent medium, and occurs optimally at pH < 9.6. Importantly, the lowering of pH from basic to neutral type ameliorates the extent of sulfidation.
