Bio-inspired synthesis of biologically and catalytically active silver chloride-anchored Palladium/Gold/Silver Trimetallic nanoparticles

Dual-Cation-Doped Pd Nanocube Supported on Aminoclay for Catalytic Reduction of 4-Nitrophenol

“…Recently, noble metals have been used to design and synthesize nanoparticles (NPs) with controlled morphology and texture because of their enhanced catalytic, optical, electronic, and surface properties. , Owing to their remarkable performance in free electrons, tightly packed structures, and large surface-area-to-volume ratio, noble metal NPs have been extensively used in the preparation of nanocatalysts. , Since the pioneering study in 2001, extensive attempts have been made on the catalytic reduction of 4-NP to 4-AP with NaBH 4 in an aqueous medium, employing various metal nanostructures as catalysts, including Pd, Pt, Au, Ag, and Ru NPs. Moreover, noble bimetallic and trimetallic NPs, such as Ag–Au, Pd–Au, Pd–Ag, Pd–Cu, and Au–Ag–Pd, have demonstrated superior catalytic performance compared to their monometallic counterparts. Falahati et al have comprehensively reviewed the advances and fundamental concepts of the catalytic reduction of 4-NP using Au NPs and illustrated their mechanisms of action .…”
