A recyclable and highly active Co3O4 nanoparticles/titanate nanowire catalyst for organic dyes degradation with peroxymonosulfate

Octahedral Co3O4/carbon nanofiber composite-supported Pt catalysts for improved methanol electrooxidation

“…The Co 2p spectra consisting of Co 2p 3/2 and Co 2p 1/2 core levels appear at $780.3 eV and $795.5 eV. The energy separation between the Co 2p 3/2 and Co 2p 1/2 peaks is $15 eV, in good agreement with a standard Co 3 O 4 sample [10]. The Co 2p 3/2 core levels are mainly observed at $779.9 eV and $780.7 eV, corresponding to the binding energies of Co 3 O 4 and Co(OH) 2 phases [11,12].…”

Novel targeted pH-responsive drug delivery systems based on PEGMA-modified bimetallic Prussian blue analogs for breast cancer chemotherapy

“…35 The peaks at 784.1 and 787.7 eV were associated with the shake-up satellite of Co 2p 3/2 . 36 These ndings suggest the mixed chemical valences of Co 2+ and Co 3+ in CoFe PBA. As for Fe 2p XPS spectrum, the peaks at the BEs of 710.2 and 723.5 eV were assigned to Fe 3+ 2p 3/2 and Fe 3+ 2p 1/2 , respectively.…”

“…The dialysis bags were placed in the thermostatic shaker with 180 rpm at 37 °C. 3 mL dialysate was then collected at the desired intervals (0.5, 2,4,6,8,10,12,14,25,30,36,54,80,108, and 120 h), followed by adding 3 mL of fresh 1× PBS.…”

Enthralling Adsorption of Different Dye and Metal Contaminants from Aqueous Systems by Cobalt/Cobalt Oxide Nanocomposites Derived from Single‐Source Molecular Precursors

“…In particular, much attention has been focused on the wastewater treatment due to their high degradation efficiency, excellent physical and chemical properties, high stability, reusability, and low toxicity ,,,,. Variety ofdifferent metal oxides and composites have been used as the adsorbents and the photocatalysts for waste water treatment purposes from aqueous solution such as including TiO 2 , ZnO, Fe 3 O 4 , SnO 2 , CuO, Co 3 O 4 etc ,,,,…”
