Porous and flexible membrane derived from ZIF-8-decorated Hyphae for outstanding adsorption of Pb2+ ion.
Journal of colloid and interface science, 2020Co-Authors: Lei Huang, Haiying Wang, Weichun Yang, Wu Yanjing, Zhihui Yang, Tao Yuan, Sikpaam Issaka Alhassan, Zhang LiyuanAbstract:Abstract Metal-organic frameworks (MOFs) based membranes with superior mechanical properties are of particular interest in purification, separation, and catalysis. Nevertheless, their fabrication still remains a grand challenge. Here, Fungus Hyphae (Mucor) were used as a robust scaffold to load the MOFs and induced the formation of porous and flexible membranes. ZIF-8 was used as a representative of MOFs. The ZIF-8@Mucor membrane was formed by the in-situ growth of ZIF-8 on Hyphae and then a vacuum filtration of the ZIF-8/Hyphae composite. ZIF-8 was effectively dispersed on the ZIF-8@Mucor membrane, and the shear modulus of ZIF-8@Mucor-3 was 864 MPa by calculation. The ZIF-8@Mucor membrane exhibited promising properties for adsorption application to remove the highly toxic Pb2+. The adsorption capacity of this membrane was as high as 1443.29 mg/g. Results from dynamic adsorption indicated that the penetration concentration of Pb2+ ions was less than 5% of the original level before 80 min whereas after 160 min, penetration concentration of Pb2+ ions was more than 90%. This study would open a new way of how to synthesize composite MOFs/bacterial membranes for energy and environment purposes.

Fungus Hyphae-supported alumina: An efficient and reclaimable adsorbent for fluoride removal from water.
Journal of colloid and interface science, 2017Co-Authors: Weichun Yang, Liyuan Chai, Shunqi Tian, Tang Qiongzhi, Haiying WangAbstract:A reclaimable adsorbent of Fungus Hyphae-supported alumina (FHSA) bio-nanocomposites was developed, characterized and applied in fluoride removal from water. This adsorbent can be fast assembled and disassemble reversibly, promising efficient reclamation and high accessible surface area for fluoride adsorption. Adsorption experiments demonstrate that the FHSA performed well over a considerable wide pH range of 3-10 with high fluoride removal efficiencies (>66.3%). The adsorption capacity was 105.60mgg-1 for FHSA, much higher than that for the alumina nanoparticles (50.55mgg-1) and pure Fungus Hyphae (22.47mgg-1). The adsorption capacity calculated by the pure content of alumina in the FHSA is 340.27mgg-1 of alumina. Kinetics data reveal that the fluoride adsorption process on the FHSA was fast, nearly 90% fluoride adsorption can be achieved within 40min. The fluoride adsorption on the FHSA is mainly due to the surface complexes formation of fluoride with AlOH and the attraction between protonated NH2 and fluoride through hydrogen bonding. Findings demonstrate that the FHSA has potential applicability in fluoride removal due to its strong fluoride adsorbility and the easy reclamation by its fast reversible assembly and disassembly feature.

Highly Flexible and Porous Nanoparticle-Loaded Films for Dye Removal by Graphene Oxide–Fungus Interaction
ACS applied materials & interfaces, 2016Co-Authors: Liyuan Zhang, Haiying Wang, Liyuan Chai, Mengran Wang, Jianying Huang, Yuekun LaiAbstract:Highly flexible and porous films with the ability to load various nanoscale adsorbents are of particular importance in the purification field. Herein, we report the sustainable and large-scale fabrication of a porous and flexible hybrid film based on the graphene oxide/Hyphae interaction at a relatively low temperature of 130 °C. Under identical conditions, such films cannot be constructed with solely graphene oxide or Hyphae. Moreover, through the addition of nanoscale building blocks [e.g., nanoscale poly(m-phenylenediamine) (PmPD) adsorbents] in the interaction process, the nanoparticles can be in situ loaded into the film. According to FTIR and XPS analyses, the film formation mechanisms mainly involve redox and cross-linking reactions between graphene oxide and Fungus Hyphae. In a proof-of-concept study, a PmPD nanoparticle-loaded hybrid film was used as a superior key component to build a flow-through adsorption device that displayed a promising adsorption performance toward dye pollutants.

Procedural growth of fungal Hyphae/Fe3O4/graphene oxide as ordered-structure composites for water purification
Chemical Engineering Journal, 2019Co-Authors: Wenkun Zhu, Tao Chen, Lichun Dai, Jia Lei, Xueyuan Bai, Jian Zhou, Liang Wang, Tao DuanAbstract:Abstract Layered core-shell structured Fungus Hyphae (FH)/Fe3O4/graphene oxide (GO) nanocomposite spheres (FFGS) were successfully prepared by successively culturing FH in Fe3O4 or GO containing mediums. This strategy was low-cost, eco-friendly and easy to scale up for the preparation of core-shell structured FH mediated materials. Batch adsorption results showed that the core-shell structured FFGS was much better in the adsorption of methyl violet (MV) and uranium (U (VI)) than FH, FH/GO, and FH/Fe3O4, which might be attributed to its lower zeta potential. Specifically, the maximum adsorption capacity of FFGS was calculated to be 117.35 and 219.71 mg/g for MV (pH 7.0) at 303 K, and U (VI) (pH 5.0) at 293 K, respectively. According to the adsorption kinetics and adsorption isotherms, the mechanism of U (VI) adsorption on FFGS was dependent on the chemical adsorption, while MV was mainly physical adsorption. Furthermore, attributed to its magnetic shell, the FFGS could easily realize controllable magnetic separation. Thus, core-shell structured FFGS would be a promising adsorbent for the removal and recovery of MV or U (VI) from waste water.

Bioassembly of fungal Hyphae/graphene oxide composite as high performance adsorbents for U(VI) removal
Applied Surface Science, 2018Co-Authors: Geng Zou, Siyi Yang, Peiheng Shi, Tao Chen, Yiren Lian, Tao Duan, Kui Zheng, Lichun Dai, Wenkun ZhuAbstract:Abstract In this paper, Fungus Hyphae/graphene oxide (FH/GO) with interesting net structure was prepared through a simple biological culture method for U(VI) removal. SEM, Zeta potential, FT-IR and XPS were applied to characterize the physicochemical properties of the resulting FH/GO composites, and batch and column adsorption experiments were conducted to elucidate their U(VI) adsorption performances and mechanisms. Results showed that FH/GO composite was highly efficient in U(VI) adsorption with a high reusability and stability. Specifically, compared to biomass (FH), the U(VI) adsorption capacity was increased by 60% for FH/GO composite at initial pH 6.0 (±0.1) and 20 °C, and the maximum U(VI) adsorption capacity for the FH/GO was 199.37 mg/g. Furthermore, the adsorption kinetics, thermodynamics and isotherms analysis demonstrated that the U(VI) adsorption on FH/GO was depended on the chemical adsorption, and it was an endothermic and spontaneous process. Therefore, these results suggested that the as-prepared FH/GO composite was promising in nuclear waste water treatment.
