Bismuth-based nanostructured photocatalysts for the remediation of antibiotics and organic dyes
Beilstein J. Nanotechnol. 2023, 14, 291–321, doi:10.3762/bjnano.14.26
- efficiencies for both ciprofloxacin and ofloxacin were recorded at a highly basic pH [187] using a magnetic Bi2WO6-biochar composite with a pHpzc of 6.75. The best performance was at pH 7. Since both antibiotics and photocatalyst were negatively charged at a basic pH, electrostatic repulsion between them was
Bio-imaging with the helium-ion microscope: A review
Beilstein J. Nanotechnol. 2021, 12, 1–23, doi:10.3762/bjnano.12.1
Self-standing heterostructured NiCx-NiFe-NC/biochar as a highly efficient cathode for lithium–oxygen batteries
Beilstein J. Nanotechnol. 2020, 11, 1809–1821, doi:10.3762/bjnano.11.163
- catalysts is highly desirable for practical applications in lithium–oxygen batteries. Herein, a heterostructure of NiFe and NiCx inside of N-doped carbon (NiCx-NiFe-NC) derived from bimetallic Prussian blue supported on biochar was developed as a novel self-standing cathode for lithium–oxygen batteries. The
- biochar was synthesized for the use in Li–O2 batteries. The electrocatalytic properties of the obtained electrodes were evaluated in a Li–O2 battery and these electrodes showed superior catalytic performance in Li–O2 batteries. Experimental Preparation of NiFe-PBA/PP-T NiFe-PBA/PP precursors were prepared
- . Conclusion In this investigation, heterostructured NiCx-NiFe-NC derived from bimetallic Prussian blue supported on biochar was successfully synthesized to improve the electronic conductivity and electrocatalytic activity, and was used as the cathode material for Li–O2 batteries. When the precursor was heated
Adsorptive removal of bulky dye molecules from water with mesoporous polyaniline-derived carbon
Beilstein J. Nanotechnol. 2020, 11, 597–605, doi:10.3762/bjnano.11.47
- because of functional carbon materials (graphene [16] or porous carbon [17]), mesoporous materials [18] and MOFs [19][20][21][22]. For example, MOFs [23][24][25], carbonaceous materials (such as carbon nanotubes, graphene, biochar and activated carbon) [26] and clay [27] have been applied in adsorptive
Synthesis of highly active ETS-10-based titanosilicate for heterogeneously catalyzed transesterification of triglycerides
Beilstein J. Nanotechnol. 2019, 10, 2039–2061, doi:10.3762/bjnano.10.200
- removal [13]. Amongst the prospective solid catalysts designed for transesterification reactions, such as calcium [14] and other metal oxides [15], metal–organic frameworks (MOFs) [10], silica-supported catalysts [16], biochar [17] and other biomass-derived catalysts [18], zeolites and molecular sieves
Development of adsorptive membranes by confinement of activated biochar into electrospun nanofibers
Beilstein J. Nanotechnol. 2016, 7, 1556–1563, doi:10.3762/bjnano.7.149
- study, a series of polyacrylonitrile (PAN)/activated biochar nanofibrous membranes (NFMs) with different loadings of biochar (0–2%, w/w) were fabricated using electrospinning. The morphology and structure of fabricated membranes was investigated by scanning electron microscopy, Fourier transform
- infrared and thermogravimetric analysis. The results showed that at 1.5% of biochar loading, the surface area reached the maximum value of 12.4 m2/g and beyond this loading value, agglomeration of particles inhibited fine interaction with nanofibrous matrix. Also, the adsorption tests using
- chlortetracycline showed that, under environmentally relevant concentrations, the fabricated adsorptive NFMs had a potential for removal of these types of emerging contaminants from water and wastewaters.
