Efficient degradation of organic dyes by heterogeneous cefdinir derived silver nanocatalyst

Cefdinir derived silver nanocatalyst (Cef-Ag (0) NPs) was successfully synthesized in aqueous solution by efficient one-pot method and effectively employed for the ultrafast catalytic degradation of Rose Bengal and Eosin Gelblich dyes. The improvement was achieved in percent degradation of toxic dyes by varying and optimizing reaction time, and amount of catalyst reducing agent concentration. The catalytic study revealed that complete reduction ∼99.9% of dye was accomplished in short period of reaction time (60 s) by efficient cefdinir derived silver nanoparticles. The calculated K (rate constant) value for RB and EG catalytic degradation was achieved 7 × 10−2 and 10 × 10−2 s−1, respectively by plotting lnC vs time (s) and result show that reaction is following first order kinetics.
