Figure 9From: Spontaneous synthesis of gold nanoparticles on gum arabic-modified iron oxide nanoparticles as a magnetically recoverable nanocatalystReusability of GAAu-MNP for the reduction of 4-NP with NaBH 4 . [Au]0 = 0.295 × 10−2 mg/mL, [4-NP] = 1.5 × 10−4 M, [NaBH4] = 1.5 × 10−2 M, 30°C.Back to article page
