“…As a final example, we present the hybrid system developed by Yimit et coworkers, who synthesized TCPP composited with graphitic carbon nitride g-C 3 N 4 material through grinding method and ethanol dispersion and employed to OWG gas sensors by surface sensitization [60]. Under different pH conditions, the TCPP-g-C 3 N 4 based sensor showed different behaviors and different optical properties depending on the aggregation extent, as confirmed by FESEM and UV-VIS studies.…”

Porphyrins and carbon nanomaterials are among the most widely investigated and applied compounds, both offering multiple options to modulate their optical, electronic and magnetic properties by easy and well-established synthetic manipulations. Individually, they play a leading role in the development of efficient and robust chemical sensors, where they detect a plethora of analytes of practical relevance. But even more interesting, the merging of the peculiar features of these single components into hybrid nanostructures results in novel materials with amplified sensing properties exploitable in different application fields, covering the areas of health, food, environment and so on. In this contribution, we focused on recent examples reported in literature illustrating the integration of different carbon materials (i.e., graphene, nanotubes and carbon dots) and (metallo)porphyrins in heterostructures exploited in chemical sensors operating in liquid as well as gaseous phase, with particular focus on research performed in the last four years.

“…Figure 2 represents the FTIR spectra of CN, TCPP, and CN/ TCPP hybrids. CN exhibits peaks in the region 1200-1700 cm À 1 (1248 cm À 1 , 1329 cm À 1 , 1424 cm À 1 , 1584 cm À 1 ) corresponding to the skeletal vibrations of aromatic CN heterocycles (CÀ N and C=N stretching) [6,11,32,43] . The peak around 809 cm À 1 represents out-of-plane bending the characteristic of tris-s-triazine units.…”

“…[2] Limited visible light absorption ability, low electrical conductivity, high recombination rates of photogenerated charge carriers and low surface area curbs the photocatalytic performance of graphitic carbon nitride. The strategies opted for circumventing the aforesaid limitations include band gap engineering and defect control, [1][2][3][4][5] surface sensitization, [3,6] morphological control, [7][8][9] elemental/molecular doping, [3,4,9,[11][12][13] co-catalyst loading, [3,6,14] exfoliation, [11] dye sensitization, [3,6,16] heterojunction formation, [3,5,8,9,14,17] etc. Modified graphitic carbon nitride has been explored for a wide range of applications including H 2 generation, [4,5,9,10,14,16,18] CO 2 reduction, [9,11,19,20] water oxidation, [21] artificial photosynthesis, [3,22] environmental remediation, [7,…”

Photocatalysis on pristine g-C 3 N 4 (CN) often suffers from fast recombination of photogenerated electrons and holes. Herein, we demonstrate the superior photocatalytic performance of free base tetrakis(4-carboxyphenyl) porphyrin (TCPP) -g-C 3 N 4 (CN/TCPP) hybrids synthesised by a facile ultrasound aided impregnation. Structural and morphological characterisation confirmed the successful formation of the hybrid via noncovalent π-π stacking. Optical/electrochemical characterisation, as well as DFT study, designates the shifting of the optical absorption edge to visible range along with inhibition of carrier recombination through enhanced charge transfer. The CN/ TCPP hybrids exhibited superior performance towards the degradation of persistent antibiotic ciprofloxacin under visible irradiation signifying its enhanced visible light sensitivity. The enhanced photocatalytic activity of CN/TCPP is ascribed to the charge transfer by through-space conjugation by migration of electrons and holes in opposite directions, which minimises the possibility of electron-hole recombination. From the LCMS data, scavenging studies, and first principles DFT analysis, the photodegradation of CIP is proposed to proceed via the destruction of the piperazine ring initiated mainly through the electrophilic attack by the holes.
