“…Bajjou et al reported that the position of the Soret band of the TPPS was not affected by the presence of RGO either. 92 Similar observations were made with neutral porphyrins like TPyP, as their absorption spectra remained largely unchanged in the presence of GBMs (Fig. 7E), 81,93 underscoring the critical role of positive charge in facilitating effective Por interaction with GBM.…”

“…1a, as a result of the reaction between the porphyrin molecules and GO, the GO-FeTCPP (Cl) nanocomposites display a (001) peak at 2θ = 9° (d-spacing = 0.95 nm), obviously lower than that of GO. The characteristic peaks of the attached catalyst were not observed clearly, which indicates the FeTCPP (Cl) complex was well dispersed on the GO as well as the peak at 2θ = 25.5° corresponding to the graphene nanosheets that follow functionalization of the GO sheets with FeTCPP(Cl) has incomplete recovery [17][18][19][20][21]. the O-H stretching.…”

Sulfur compounds are one of the major problems and undesirable contaminants in the oil and gas industries. To address this issue, mercaptan removal from the gas stream in a fixed bed reactor under nanocatalyst was investigated. In this work, meso-tetrakis (4-carboxyphenyl) porphyrinatoiron (III) chloride-supported graphene oxide [GO-FeTCPP (Cl)] nanocatalyst was synthesized and adsorption of mercaptan on nanocatalyst was studied. Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), X-ray diffraction (XRD), BET, and Raman spectroscopy analysis were used to characterize the nanocatalyst. This experiment investigated how temperature and Gas Hour Space Velocity (GHSV) parameters affect the mercaptan removal in presence of nanocatalyst. The research results confirmed that the reaction rate improves with increasing temperature and decreasing GHSV. According to the results, at 100 °C and GHSV of 1000 h −1 , the maximum conversion (~ 96%) of reaction was reached.

We calculated electrical characteristics of eight compounds based on aryl-cyano-methylene-quinone mono-oximes using density functional theory (DFT) with base set B3LYP/6-311G (d). Some of theoretical factors, such as energy of HOMO (EHOMO), energy of LUMO (ELUMO), and Gap energy (Egap) are highly relevant in the photovoltaic sector. On the other hand, we investigated our results by determining electronic and spectroscopic properties using TD-DFT and with base set B3LYP/6-311G (d), in order to define the wavelengths of studied molecules, tracing the visible and ultra-violet spectrum, and determine the transition states. The achieved results and developed attributes show that these molecules could be extremely efficient in the renewable energy industry.
