Preparation and characterization of gold nanoparticles and nanowires loaded into rod-shaped silica by a one-step procedure

A new method for incorporating polyethyleneimine (PEI) in algal beads: High stability as sorbent for palladium recovery and supported catalyst for nitrophenol hydrogenation

“…Several sorbents have been tested including activated carbon [2], modified chitosan [3], alginate beads [4], algal foams [5], etc. The immobilization of catalyst particles upon biosorbents has been shown to be a promising way to produce active catalysts as a potential alternative to traditional homogenous catalysts [6][7][8]. Vincent and Guibal [9] successfully prepared chitosansupported palladium catalyst through two steps: sorption and chemical reduction and found it efficient for chromate reduction.…”
