Porous carbon nitride (PCN) material has been considered as a potential candidate to solve the above problem due to the abundant reaction sites, large specific surface area and narrow band gap. Recently, substantial research focus on promoting photocatalytic activity of PCN-based material via improving photogenerated carrier separation and band gap structure has been completed. However, only a few works summarize and discuss the results of research on photocatalytic antibiotic degradation by PCN-based photocatalysts in recent years. Thus, a review on recent developments in PCN-based photocatalysts research is urgently needed to further promote its advancement. In this review, the synthesis strategies, structure design and photocatalytic application of antibiotic degradation over PCN-based photocatalysts are listed in detail. Finally, a brief conclusion has been discussed deeply, which focuses on the future challenges and expectations of PCN-based photocatalysts for photocatalytic antibiotic degradation. This review offers a novel viewpoint on the use of PCN-based material in photocatalytic antibiotic degradation and highlights its significant potential as a photocatalyst. In short, the application of PCN-based materials in the photocatalytic degradation of antibiotics is very promising, according to objective assessments.

“…Uracil molecule physisorption on the B40 fullerene surface with a binding distance of 2.38Å is investigated using non-equilibrium Green's function and density functional theory [3]. C-doped porous carbon nitrides prepared from uracil mediated molecule with cyanuric acid showed effective electron hole separation and broaden the light absorption range [4]. The uracil complexes of several metal ions, such as Fe(III), Co(III), Ni(II), Cu(II), Zn(II), Cd(II), and Pd(II) have been reported earlier [5][6][7][8][9][10][11][12][13].…”

“…However, the polymeric mixed ligand complexes of uracil or substituted uracil generally involve N(1) and C(4)=O in bonding with metal ion [11][12][13]. The uracil-metal complexes can have square planar and octahedral geometries [3,4]. Uracil's substituted in position five stand out in bioactivity, with various biological activities including antiviral properties, anticancer, cytotoxic, anti-mycobacterial, and antitumor, to antibacterial [14][15][16][17][18][19][20][21][22][23].…”

ABSTRACT. Magnesium, calcium, strontium, and barium complexes of uracil were prepared in a 2:1 ligand to metal ratio to investigate the ligational character of the uracil (Ura). The modes of chelation were explained depending on elemental analyses, FT. IR, 1H–NMR spectra as well as scanning electron microscopy. Uracil has two donation sites either through N(3) and C(2)=O, or through N(3) and C(4)=O with the molecular formulas [M(Ura)2(H2O)2]Cl2 where M = Mg(II), Ca(II), Sr(II) and Ba(II) . The morphological surface and particle size of uracil metal complexes were determined using SEM and TEM. The thermal behaviors of the complexes were studied by the TGA (DTG) technique. The data obtained agreed well the proposed structures and showed that the complexes were finally decomposed to the corresponding metal oxide. The thermodynamic parameters are calculated from the thermal analysis curves using the Coats–Redfern and Horowitz–Metzger methods. The negative values of deduced the ordered structures of the prepared complexes compared to their starting reactants. Antibacterial activity of ligands and complexes is evaluated with two types of bacteria Staphylococcus aureus (gram‐positive) and Escherichia coli (gram‐negative) by the agar-well diffusion technique using DMSO as a solvent.

Fast production of hydrogen and oxygen in large amounts at an economic rate is the need of the hour to cater to the needs of the most awaited hydrogen energy, a futuristic renewable energy solution. Production of hydrogen through a simple water splitting through visible light photocatalytic approach using sunlight is considered as one of the most promising and sustainable approaches for generating clean fuels. For this purpose, a variety of catalytic techniques and novel catalysts are being investigated. Among these catalysts, carbon nitride is presently deemed as one of the best candidates for the visible light photocatalysis due to its unique molecular structure and adequate visible‐range band gap. Its band gap can further be engineered by structural and morphological manipulation or by, doping/hybridization. Among numerous synthetic approaches for carbon nitrides, supramolecular self‐assembly is one of the recently developed elegant bottom‐up strategies as it is bio‐inspired and provides a facile and eco‐friendly route to synthesise high surface area carbon nitride with superior morphological features and other semiconducting and catalytic properties. The current review article broadly covers supramolecular self‐assembly synthesis of carbon nitride nanostructures and their photocatalytic water splitting application and provides a comprehensive outlook on the future directions.This article is protected by copyright.
