Catalytic Activity of Bimetallic (Ruthenium/Palladium) Nano‐alloy Decorated Porous Carbons Toward Reduction of Toxic Compounds

Abstract Chicken feather‐derived high‐surface‐area porous activated carbon (CFAC) material was prepared using chemical activation. A new composite composed of Ru‐Pd nanoparticles supported on CFAC (Ru‐Pd@CFAC) has been prepared by microwave‐thermal reduction in the presence of the support. Characterization by XRD, Raman, BET, FE‐SEM/TEM, FT‐IR, TGA, XPS, HAADF‐STEM‐EDS, H 2 ‐chemisorption, H 2 ‐TPR, and ICP‐AES was used to analyze the catalyst. This catalyst is found to be efficient for the reduction of hexavalent chromium (Cr VI ), potassium ferricyanide (K 3 [Fe(CN) 6 ]), 4‐nitrophenol (4‐NP), and pendimethalin (PDM), at room temperature, and remains stable, even after several repeated runs. Moreover, it showed excellent catalytic activity compared with the monometallic counterparts.
