Abstract

Although molecular hydrogen is very useful in environmentally clean technology, its usage also comes with some associated hazards and hence the need to use hydrogen donor compounds such as sodium hypophosphite in the generation of hydrogen as electron donor. In this study, sodium hypophosphite was utilized as a source of hydrogen and as an electron donor in the biogenic reduction of palladium onto the surface of bacterial cells (aerobic and anaerobic bacteria) to produce bio-nanoparticles with potential in the dehalogenation of chlorinated pollutants like chlorobenzene. The purpose of this paper is to provide a facile and cost effective approach to the synthesis of biogenic nanoparticles using sodium hypophosphite as a hydrogen donor compound.
