Amorphous metal–organic framework (aMOF)-based
materials have attracted considerable attention as an emerging class
of nanomaterials. Herein, novel microorganisms@aMIL-125
(Ti) composites including yeast@aMIL-125 (Ti), PCC
6803@aMIL-125 (Ti), and Escherichia
coli@aMIL-125 (Ti) composites were
respectively synthesized by self-assembling aMOFs
on the microorganisms’ surface. The functional groups on the
microorganisms’ surface induced structural defects and participated
in the formation of aMIL-125 (Ti) composites. Finally,
the application of microorganisms@aMIL-125 (Ti) composites
for the removal of glyphosate from aqueous solution was selected as
a model reaction to illustrate their potential for environmental protection.
The present method is not only economical but also has other advantages
including ease of operation, environmentally friendly assay, and high
adsorption. The maximum adsorption capacity of aMIL-125
(Ti) was 1096.25 mg g–1, which was 1.74 times that
of crystalline MIL-125 (Ti). Therefore, the microorganisms@aMOFs composites will have broad application prospects in
energy storage, drug delivery, catalysis, adsorbing toxic substances,
sensing, encapsulating and delivering enzymes, and in other fields.
