Microbial production and environmental applications of Pd nanoparticles for treatment of halogenated compounds.
New biological inspired methods were recently developed to recover precious metals from waste streams and to concomitantly produce palladium nanoparticles on bacteria, that is, bio-Pd. This technology offers a variety of opportunities, as the process can considered to be green, tunable, affordable and scalable. The nanoparticle formation and the specific role of the bacteria in the reclamation process are highlighted. The effective performance of bio-Pd as catalyst in dehalogenation reactions, as well as in hydrogenation, reduction and CC coupling reactions has been extensively described in literature. Especially dehalogenation of environmental contaminants represents a promising market for application of bio-Pd. Therefore, several treatment technologies based on bio-Pd in the different environmental compartments are considered and domains, in which bio-Pd can be used at full scale are described. Finally, the perspectives for implementation of the bio-Pd technology in the future are set forward.
