Construction of C₆₀-decorated SWCNTs (C₆₀-CNTs)/bismuth-based oxide ternary heterostructures with enhanced photocatalytic activity

Abstract

Ternary heterostructured C60-CNTs/Bi2MoO6 and C60-CNTs/BiVO4 photocatalysts were successfully synthesized. They exhibited enhanced photocatalytic activity.

Preparation and photocatalytic activity characterization of activated carbon fiber–BiVO4 composites

“…The abundance of delocalized electrons in their conjugated p-systems makes carbon materials promising supports, including fullerenes (C 60 ), carbon nanotubes (CNTs), graphitic carbon nitride (g-C 3 N 4 ), and activated carbon bers (ACFs), which can potentially enhance charge separation and transport within the immobilized catalyst. 14,15 Among them all, it was observed that the construction of a semiconductor heterojunction can greatly promote photocatalytic activity. 16,17 Recently, ACFs have attracted much attention as pollutant adsorbents because of their high surface areas, diverse functional groups, narrow pore size distributions, and many raw material precursors.…”

Room‐Temperature Synthesis and Enhanced Photocatalytic Performance of BiOCl Microsphere

“…Taking the sample S1 as an example, the high‐resolution of Bi 4 f, Cl 2p and O 1s is respectively analyzed. The two relatively strong peaks at 159.2 and 164.6 eV are assigned to Bi 4f7/2 and Bi 4f5/2 of Bi 3+ , as shown in Figure b. The Cl 2p spectrum in Figure c is resolved into two peaks located at 198 and 199.8 eV, which belong to the binding energies of Cl 2p3/2 and Cl 2p1/2, respectively .…”

Fabrication of the heterojunction catalyst BiVO 4 /P25 and its visible-light photocatalytic activities

“…These included: Ag 2 CO 3 /BiVO 4 ; Ag/Ag 2 O–BiVO 4 ; BiVO 4 :Ag; BiVO 4 /BiOCl; BiVO 4 /BiOBr; BiPO 4 /BiVO 4 ; Fe 2 O 3 /3DOM BiVO 4 ; BiVO 4 /InVO 4 ; BiVO 4 /Bi 2 WO 6 ; BiVO 4 /Bi 2 Ti 2 O 7 ; m-BiVO 4 /t-BiVO 4 , and so on [17–28]. Also, carbonaceous materials, such as activated carbon (AG), carbon dots, fullerene (C 60 ), carbon nanotubes and graphene have been widely employed for enhancement of photocatalytic activity of BiVO 4 [29]. Graphitic carbon nitride (g-C 3 N 4 ) as a metal-free polymeric semiconductor doped on a Bi-based composite could improve the photocatalytic performance of Bi-based materials [30,31].…”
