Bioorg Chem 2023; 141:106804. [PMID: 37806049 DOI: 10.1016/j.bioorg.2023.106804] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2023] [Revised: 08/20/2023] [Accepted: 08/21/2023] [Indexed: 10/10/2023]
Abstract
In this study, we bring forward a green and novel eco-friendly strategy for the fabrication of Ag/g-C3N4 nanocomposite via a fast in-situ generation method using Ferula Gummosa extracts as both stabilizer and reducing agent. Ag/g-C3N4 nanocomposite was analyzed by Fourier transform infrared spectra (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX-MAP), and transmission electron microscopy (TEM). After procurement and characterization, the catalytic activity of the prepared reagent was surveyed in the synthesis of a new series of depsipeptides using aspirin/ketoprofen, cyclohexyl isocyanide, and aryl aldehydes at ambient temperature in EtOH/H2O as a green media. Taking into account the economic and environmental facets, the method bestows some advantages such as using plant extracts as green media for the preparation of Ag nanoparticles, simple work-up procedure, mild reaction conditions, short reaction times, and high yields of the products. Additionally, the Ag/g-C3N4 nanocomposite catalyst can be recycled effectually and reused several times without a substantial loss in reactivity.

Facile preparation of porphyrin@g-C 3N 4/Ag nanocomposite for improved photocatalytic degradation of organic dyes in aqueous solution. ENVIRONMENTAL RESEARCH 2023; 231:115984. [PMID: 37156354 DOI: 10.1016/j.envres.2023.115984] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/03/2023] [Revised: 04/13/2023] [Accepted: 04/24/2023] [Indexed: 05/10/2023]
Abstract
In the quest of improving the photocatalytic efficiency of photocatalysts, the combination of two and more semiconductors recently has garnered significant attention among scientists in the field. The doping of conductive metals is also an effective pathway to improve photocatalytic performance by avoiding electron/hole pair recombination and enhancing photon energy absorption. This work presented a design and fabrication of porphyrin@g-C3N4/Ag nanocomposite using acid-base neutralization-induced self-assembly approach from monomeric porphyrin and g-C3N4/Ag material. g-C3N4/Ag material was synthesized by a green reductant of Cleistocalyx operculatus leaf extract. Electron scanning microscopy (SEM), X-ray diffraction (XRD), FT-IR spectroscopy, and UV-vis spectrometer were utilized to analyse the properties of the prepared materials. The prepared porphyrin@g-C3N4/Ag nanocomposite showed well integration of porphyrin nanostructures on the g-C3N4/Ag's surface, in which porphyrin nanofiber was of the diameter in nanoscales and the length of several micrometers, and Ag NPs had an average particle size of less than 20 nm. The photocatalytic behavior of the resultant nanocomposite was tested for the degradation of Rhodamine B dye, which exhibited a remarkable RhB photodegrading percentage. The possible mechanism for photocatalysis of the porphyrin@g-C3N4/Ag nanocomposite toward Rhodamine B dye was also proposed and discussed.

Abstract
Background:
Rapid escalation in textile, paper, pesticides, pharmaceuticals and several other chemical based
manufacturing industries due to amplification in human requirements have proportionately contributed to the extreme
contamination of water ecosystem, resulted from the discharge of toxic pollutants from industries. Effluents from textile
industries are comprised of coloured dyes like Rhodamine B, Methyl Orange, Methylene Blue and phenolic compounds
which deserve special mention owing to their non-biodegradable, carcinogenic and severe detrimental nature. Urgent
needs to ameliorate this fast declining environmental situation are of immense necessity in current scenario.
Objectives:
Objectives: In this regard, graphitic carbon nitride (GCN) is a distinguished material for water purification-based
applications because of its exclusive characteristics making it highly prospective for degradation of toxic dyes from water
by catalysis and adsorption techniques. GCN has been a material of conspicuous interest in recent times owing to its two
dimensional sheets like structure with favourable surface area, and cost-effective synthesis approaches along with high
production yield. This article presents a detail study of different aspects of GCN as a material of potential for water
purification. Through extensive literature survey it has been shown that GCN is an effective material to be used in the
fields of application. Several effective procedures like catalysis or adsorption for removal of dyes from water have been
discussed with their basic science behind.
Conclusions:
This systematic effort shows that GCN can be considered to be one of the most efficient water purifier with
further advantages arising from its easy and cost effective large scale synthesis.
