Heterogeneous catalytic reduction of anthropogenic pollutant, 4-nitrophenol by silver-bionanocomposite using Cylindrocladium floridanum

► Synthesis of nanosilver-biomass composite using fungus, Cylindrocladium floridanum was described. ► TEM analysis showed the distribution of AgNPs on the mycelia with 5-55 nm in size. ► Biocomposite-AgNPs were used as heterogeneous catalyst in the degradation of 4-NP. ► The reduction of organic pollutant, 4-NP followed pseudo-first-order kinetic model.
