Graphene wrapped Copper Phthalocyanine nanotube: Enhanced photocatalytic activity for industrial waste water treatment

A novel and low-cost CuPc@C catalyst derived from the compounds of sunflower straw and copper phthalocyanine pigment for oxygen reduction reaction

“…In the XRD pattern of CuPc@C series composite catalysts, a broad peak around 26° can also be clearly seen, which corresponds to the (002) crystal plane of graphite. 35 Moreover, it can be found that with the increase of heat treatment temperature, the broad peak of CuPc@C-800 is stronger than CuPc@C-700 and CuPc@C-750, showing a higher degree of graphitization and the structure of sunflower straw biochar has changed into a more ordered form. When the temperature is further increased to 850 °C and 900 °C, the broad peak of CuPc@C-850 becomes weaker, while the broad peak of CuPc@C-900 becomes stronger.…”

Intercalation of Copper Phthalocyanine Within Bulk Graphite as a New Strategy Toward the Synthesis of CuO-Based CO Oxidation Catalysts

“…They stabilize graphene suspensions by intercalation between the sonically-destabilized basal planes, generating 3D systems in solution and hybrid systems in the solid-state. However, it is interesting that, when it comes to metal-containing dyes, such as copper phthalocyanine (CuPc) for example, most work related to the chemical synthesis of functional CuPc/carbon composites involve graphite oxide (Chunder et al, 2010 ; Mensing et al, 2012 ; Mukherjee et al, 2017 ) and high surface area, functionalized carbons (Ding et al, 2012 ; Goenaga et al, 2014 ; Reis et al, 2014 ). There is to our knowledge no example of direct chemical deposition of CuPc on low surface area, bare hydrophobic graphite via non-covalent interactions.…”

“…Besides, the reported carbon-supported CuPc are either used as such, i.e., with no further transformation of the immobilized CuPc complex (Pakapongpan et al, 2014 ; Reis et al, 2014 ; Bian et al, 2020 ), or after pyrolysis at high temperatures to modify the carbon support (Ding et al, 2012 ; Goenaga et al, 2014 ). Their main applications are electrochemistry (Ding et al, 2012 ; Goenaga et al, 2014 ; Pakapongpan et al, 2014 ; Reis et al, 2014 ; Bian et al, 2020 ) and photocatalysis (Mukherjee et al, 2017 ). When associated with other active supports, CuPc are also used for catalytic oxidations (Raja and Ratnasamy, 1996 ; Sorokin, 2013 ) and as co-catalyst for photoelectrochemical water splitting (Li et al, 2019 ).…”

The Effects of Asymmetry in Combination with Reduced Graphene Oxide Nanosheets on Hydrazine Electrocatalytic Detection on Cobalt Phthalocyanines

“…Metallophalocyanines (MPcs) are two-dimensional tetrapyrrolic macrohetecycles containing 18 delocalised πelectrons which are responsible for their intense absorption in the red/near-infrared region [1][2][3][4][5]. MPcs are widely used in different fields such as dye-sensitized solar cells [6], photodynamic therapy [7], non-linear optics [8], fuel cells [9] photocatalysis [10], and electrocatalysis [11,12]. Cobalt phthalocyanines (CoPcs) are most widely studied as electrocatalysts.…”
