Diverse Catalytic Applications

Caption

Diverse catalytic applications of tunable functional E. coli biofilms with anchored nano-objects. (a) The biofilm-anchored Au NPs enable the recyclable catalytic reduction of the toxic p-nitrophenol (PNP) into the harmless p-aminophenol (PAP). (b) The biofilm-anchored heterogeneous nanostructures (Au NPs/Cd0.9Zn0.1S QDs) photo-catalyze the degradation of organic dyes to low-toxic products based on facile light-induced charge separation. (c) The biofilm-anchored quantum dots coupled with engineered strain enable photo-induced hydrogen production. Electrons are transferred from QDs to hydrogenase using methyl viologen (MV) as a mediator.
