Synergetic effects of graphene–CoPc/silk fibroin three-dimensional porous composites as catalysts for acid red G degradation

Abstract

The disposal of dye wastewater is one of the hotspots of scientific research, and graphene–CoTAPc–SF composites exhibit more effective catalytic abilities.

A high-sensitive room temperature gas sensor based on cobalt phthalocyanines and reduced graphene oxide nanohybrids for the ppb-levels of ammonia detection

“…More importantly, the unique planar 18π-electron-conjugated structure of MPcs allows them to be closely coupled with the rGO by π–π interactions. 25 On the one hand, the MPcs provide more gas sensing active sites for selective NH 3 adsorption. On the other hand, rGO provides fast and efficient charge transfer.…”

Cobalt phthalocyanine sensitized MOF on MOF: UiO-66@MIL-88B(Fe)/CoTAPc, photocatalytic activity in the degradation of acid black 210

“…The X-ray diffraction data for the single CoTAPc, UiO-66 and MIL-88B(Fe) are well consistent with those in the literature. 48,49 And in the pattern of UiO-66@MIL-88B(Fe), all diffraction peaks are attributed to UiO-66 and MIL-88B(Fe) with high diffraction intensity confirming the successful construction of the binary UiO-66@MIL-88B(Fe) with higher crystallinity. When CoTAPc was introduced, the PXRD pattern of ternary UiO-66@MIL-88B(Fe)/CoTAPc presents the characteristic diffraction being similar to that of binary UiO-66@MIL-88B(Fe), and no obvious peak for CoTAPc could be observed which may be due to the relatively poor crystallinity of CoTAPc.…”

Collagen and Silk Fibroin as Promising Candidates for Constructing Catalysts

“…In addition, the RSF matrix was also used as a protective material for the Fe 3 O 4 to isolate air and water, giving the Fe 3 O 4 nanoparticles significant stability and maintaining peroxidase-like activity. Hui Ma [ 117 ] used RSF gel as the backbone of reduced GO (RGO) and cobalt tetra-amine phthalocyanine (CoTAPc) to prepare a gel catalytic system (RGO-CoTAPc/SF) ( Figure 5 ). The RGO-CoTAPc/SF composite presented a thin-walled microporous interconnection network with a large specific surface area, and the CoTAPc molecules were homogeneously anchored on the RGO sheet.…”
