Photocatalyst-coated carbon microtube electrodes: Preparation and characterization of their properties and photocatalytic degradation of methylene blue

Microwave catalytic activities of MFe2O4@CMT (M = Ni, Co) supported catalysts for the degradation of dimethyl phthalate

“…Our previous work tested the electrochemical impedance spectroscopy (EIS) of the prepared photocatalyst, conrming that the connement effect of CMT could improve the separation and transfer of electron-hole pairs to improve the degradation efficiency. 23 This material also showed a higher degradation performance than that in the related literature (Table S5 †). 7a and b), respectively.…”

“…It can be observed that the characteristic reflection peaks of AC, PCNF, and PCCF appeared at the 2 θ values of 20.64° ( d 100 ), 26.43° ( d 011 ), 36.15° ( d 110 ), 43.099° ( d 211 ), and 62.04° ( d 204 ), corresponding to SiO 2 (JCPDF # 74-1811), similar to the finding reported for corncob in which SiO 2 was preserved during calcination. 23,24 However, the main peaks shift to higher 2 θ values when loaded with NiFe 2 O 4 or CoFe 2 O 4 , indicating a decrease in the crystal interplanar distances of SiO 2 . Besides, the decrease in the diffraction peak intensities is probably owing to the dilution of the crystal structure of SiO 2 by doping with NiFe 2 O 4 or CoFe 2 O 4 .…”

“…Corncob powder was designated as CC, and acidified corncob powder was prepared according to our previous work, 23 which was designated as AC. The precursor aqueous (PA) solution was obtained by mixing 100 mL 1.5 M Fe(NO 3 ) 3 with 100 mL 0.75 M Co(NO 3 ) 2 or Ni(NO 3 ) 2 , respectively.…”

“…Carbon microtubes (CMT) based on corncob with a tubular structure and low density were used as a catalyst carrier, which could improve the interaction between the catalyst and the contaminant, and further facilitate electron transfer to enhance the photocatalysis performance. 23 However, the use of CMT as a carrier of ferrite to form light MW-absorbing materials has been rarely studied.…”

Construction of crystalline cadmium complex based on 1,4,5,8‐naphthalene diimide derivative and photocatalytic degradation about organic dyes

“…As reported in the literature, •OH in the reaction can be captured by isopropanol, h + can be captured by methanol, and •O 2 − can be captured by p ‐benzoquinone. [ 42,43 ] To investigate which active substance is responsible, we added three active substance scavengers (1 ml): isopropanol (IPA), methanol, and p ‐benzoquinone (BQ) under the same experimental conditions (Figure 11). It can be see that the degradation rate of MG did not have any change after adding methanol.…”
