Bio-template Route for the Facile Fabrication of TiO2@Bacillus subtilis Composite Particles and Their Application for the Degradation of Rhodamine B

Synergistic Enhancement in Catalytic Performance of Superparamagnetic Fe3O4@Bacilus subtilis as Recyclable Fenton-Like Catalyst

“…Comparing Figure 2c The crystallographic structure of the as-obtained products was determined by XRD analysis (Figure 2a). The broad peak around 2θ = 20 • shows that B. subtilis is amorphous (black curve) [13,15] The crystallographic structure of the as-obtained products was determined by XRD analysis (Figure 2a). The broad peak around 2θ = 20° shows that B. subtilis is amorphous (black curve) [13,15].…”

“…The broad peak around 2θ = 20 • shows that B. subtilis is amorphous (black curve) [13,15] The crystallographic structure of the as-obtained products was determined by XRD analysis (Figure 2a). The broad peak around 2θ = 20° shows that B. subtilis is amorphous (black curve) [13,15]. All the diffraction peaks of Fe3O4 MNPs (blue curve) could be readily indexed as face-centered cubic structured Fe3O4, which coincides well with the standard data (JCPDS card No.…”

“…Lately, microorganisms employed as support materials has being attracting great interest because of their major advantages such as ample resources, environmentally friendliness, and abundant functional groups [13]. Bacillus subtilis is a kind of genus Bacillus and can be easily found in water, soil, air, and decomposing plant matter [13][14][15].…”

“…Bacillus subtilis is a kind of genus Bacillus and can be easily found in water, soil, air, and decomposing plant matter [13][14][15]. Thus, owing to its distinguished physicochemical/biological properties, B. subtilis has been selected as an ideal candidate for the synthesis of composite materials for organic pollutants removal [13][14][15][16].…”

Degradation of tetracycline hydrochloride by heterogeneous Fenton-like reaction using Fe@Bacillus subtilis

“…20 Therefore, such coexistence of peritrichous structure and the hydrophilic functional groups in the framework of B. subtilis cell wall provides plentiful absorption sites and excellent absorbability, which makes a good reason to utilize B. subtilis as a support to synthesize micro-nano photocatalytic composite materials. 17,21 However, no one has reported the synthesis of Fe-catalyst materials with B. subtilis cells as support material. Therefore, based on what has been illustrated above, we rstly present a Fe@B. subtilis composite material loaded with Fe-ions as an immobilized catalyst being applied to decompose antibiotics by Fenton-like reactions.…”
