“…As we all know, structure engineering of hybrid materials relying on non-covalent interactions also plays an important role in constructing photocatalysts, modulating related properties, and improving the photocatalytic performance [34][35][36][37][38][39][40][41][42][43]. Assembled structures can be prepared through intermolecular non-covalent interactions, such as hydrogen bonding interactions, Van der Waals interactions, and π-π stacking interactions [40,44,45].…”

“…On the other hand, under the influence of non-covalent interactions, hybrid materials possess different structural features and photoelectric properties, and thus exhibit excellent photocatalytic performance. For example, non-covalent functionalized composites containing polyterthiophene/TiO 2 and porphyrin/TiO 2 show more effective charge separation and efficient light harvesting than those of pristine TiO 2 [34][35][36][37]42]. The band gap of carbon nitride (CN) could be modulated by compositing with reduced graphene (GR) oxide via π-π stacking interaction [40].…”

Structure engineering of hybrid materials has been proved to be an efficient method to screen out superior photocatalysis. The distribution and bonding environment of covalent linkage segments can be well regulated through structure decoration. Here, we propose a controlled strategy to optimize the photocatalytic performance of hybrid catalysts. Systematic adjusting of the performance can be achieved by introducing organic components into the carbon supporter. Under the guidance of this strategy, fluoride graphdiyne (FGDY) and phloroglucinol regulating FGDY (P-FGDY) is compounded with titanium dioxide (TiO2) under solvent thermal condition to obtain hybrid catalyst FGDY/TiO2 and P-FGDY/TiO2, respectively. Notably, the as-prepared P-FGDY/TiO2 exhibits superior enhancements towards photocatalytic degradation of rhodamine B, methylene blue, and levofloxacin under visible-light irradiation compared with FGDY/TiO2. These enhanced photocatalytic activities stem from the fact that the regulation of FGDY could further increase the photogenerated electron and hole separation efficiency of hybrid catalyst. This work provides a novel regulating pathway to optimize the photocatalytic activity of carbon-based hybrid photocatalysis material systems.

“…Porphyrins and related macrocycles are photosensitisers with rich photochemical and photophysical properties [ 31 , 32 , 33 , 34 ]; they are used as catalysts for the oxidation of various organic compounds [ 35 , 36 , 37 ], as singlet oxygen sources for photodynamic therapy [ 38 , 39 , 40 ], and in different types of sensors [ 41 ], etc. Over the past few decades, the antioxidant activity of porphyrins has been extensively investigated due to the unique redox properties of a macrocyclic conjugated π-system.…”

In this study, organo-inorganic nanohybrids LHGd-MTSPP with enzyme-like activity were prepared by in situ intercalation of anionic 5,10,15,20-tetrakis-(4-sulfonatophenyl)porphyrin and its complexes with Zn(II) and Pd(II) (MTSPP, M = 2H, Zn(II) and Pd(II)) into gadolinium layered hydroxide (LHGd). The combination of powder XRD, CHNS analysis, FT-IR, EDX, and TG confirmed the layered structure of the reaction products. The basal interplanar distances in LHGd-MTSPP samples were 22.3–22.6 Å, corresponding to the size of an intercalated tetrapyrrole molecule. According to SEM data, LHGd-MTSPP hybrids consisted of individual lamellar nanoparticles 20–50 nm in thickness. The enzyme-like activity of individual constituents, LHGd-Cl and sulfoporphyrins TSPP, ZnTSPP and PdTSPP, and hybrid LHGd-MTSPP materials, was studied by chemiluminescence analysis using the ABAP/luminol system in phosphate buffer solution. All the individual porphyrins exhibited dose-dependent antioxidant properties with respect to alkylperoxyl radicals at pH 7.4. The intercalation of free base TSPP porphyrin into the LHGd preserved the radical scavenging properties of the product. Conversely, in LHGd-MTSPP samples containing Zn(II) and Pd(II) complexes, the antioxidant properties of the porphyrins changed to dose-dependent prooxidant activity. Thus, an efficient approach to the design and synthesis of advanced LHGd-MTSPP materials with switchable enzyme-like activity was developed.

Biomimetic heterogeneous catalysts were prepared by immobilization of meso‐tetrakis(4‐carboxyphenyl)porphyrinatomanganese(III) acetate (MnTCPP) and meso‐tetrakis(4‐carboxyphenyl)porphyrinatoiron(III) chloride (FeTCPP) on graphitic carbon nitride (g‐C3N4) nanosheets. The anchored catalysts were characterized by various techniques such as scanning electron microscopy, thermogravimetric analysis, powder X‐ray diffraction, ultraviolet visible, photoluminescence, flame atomic absorption, and Fourier transform infrared spectroscopy. The thermogravimetric analysis demonstrated that the prepared catalysts were thermally stable up to almost 350°C, exhibiting high thermal stability. In the following, the catalytic efficiency of the prepared nanocatalyst was also investigated for the oxidation of various olefins with hydrogen peroxide (as a green oxidant) and the effect of various parameters which may affect the catalytic efficiency was optimized. The maximum conversion (100% for α‐methylstyrene and 97% for cyclooctene) was obtained in the presence of MnTCPP@C3N4. The Mn porphyrin nanocatalyst shows higher catalytic efficiency compared to the Fe porphyrin.
