“…In a similar work, Jia et al fabricated Fe3O4/g-C3N4 via a hydrothermal route and studied its visible light photocatalytic performance towards RhB decomposition [146]. In both studies, higher photocatalytic performance was observed over the nanocomposites compared to Fe3O4 and g-C3N4 individually, reaching 95.5% in 60 min [146] and 96.5% in 100 min [77] for RhB and 2,4,6-TCP, respectively. Coupling g-C3N4 with Fe3O4 improved charge separation since only g-C3N4 is excited by visible light, and the electrons in the conduction band quickly transfer to Fe3O4, where they are captured by oxygen to form the radical species.…”

Organic and inorganic compounds utilised at different stages of various industrial processes are lost into effluent water and eventually find their way into fresh water sources where they cause devastating effects on the ecosystem due to their stability, toxicity, and non-biodegradable nature. Semiconductor photocatalysis has been highlighted as a promising technology for the treatment of water laden with organic, inorganic, and microbial pollutants. However, these semiconductor photocatalysts are applied in powdered form, which makes separation and recycling after treatment extremely difficult. This not only leads to loss of the photocatalyst but also to secondary pollution by the photocatalyst particles. The introduction of various magnetic nanoparticles such as magnetite, maghemite, ferrites, etc. into the photocatalyst matrix has recently become an area of intense research because it allows for the easy separation of the photocatalyst from the treated water using an external magnetic field. Herein, we discuss the recent developments in terms of synthesis and photocatalytic properties of magnetically separable nanocomposites towards water treatment. The influence of the magnetic nanoparticles in the optical properties, charge transfer mechanism, and overall photocatalytic activity is deliberated based on selected results. We conclude the review by providing summary remarks on the successes of magnetic photocatalysts and present some of the future challenges regarding the exploitation of these materials in water treatment.

When a single metal fails to promote an efficient Suzuki-Miyaura coupling reaction at ambient temperature, the synergistic cooperation of two distinct metals might improve the reaction. To examine the synergistic effect of palladium and nickel for catalyzing Suzuki coupling reaction, g-C 3 N 4 supported metal nanoparticles of PdO, NiO and Pd-PdO-NiO were prepared, characterized and their catalytic activities evaluated over different aryl halides at room temperature and 78°C.The morphological characterization of Pd-PdO-NiO/g-C 3 N 4 demonstrated that the bimetallic particles were uniformly dispersed over the g-C 3 N 4 layers with diameters ranging from 3.5-7.7 nm. XPS analysis showed that nanoparticles of Pd-PdO-NiO consisted of Pd(II), Pd(0) and Ni(II) sites. The experiments performed on the catalytic activity of Pd-PdO-NiO/g-C 3 N 4 showed that the prepared catalyst demonstrated an efficient activity without using toxic solvents.

A magnetically separable graphitic carbon nitride nanocomposite (Fe3O4/g‐C3N4) as a catalyst for the three‐component condensation reactions of carbonyl compounds, amines and trimethylsilylcyanide was thoroughly investigated. The reaction of these three components was found to be efficient, economical and green and took place in the presence of a catalytic amount of the magnetically separable catalyst to yield the corresponding α‐aminonitriles in good to excellent yields. The prepared nanocomposite was characterized using scanning electron microscopy and energy‐dispersive X‐ray and Fourier transform infrared spectroscopies. The nanocomposite was also found to be reusable could be recovered easily and reused several times without distinct deterioration in its catalytic activity.
