A facile mechanochemical preparation of Co3O4@g-C3N4 for application in supercapacitors and degradation of pollutants in water

Highly dispersive Co3O4nanoparticles incorporated into a cellulose nanofiber for a high-performance flexible supercapacitor

“…7,8 SCs are usually categorized into two types on the basis of energy storage mechanism: electrical double layer (EDLC) 9 and pseudocapacitor types. 10 Among them, pseudocapacitors have the benefit of reversible faradaic reactions occurring near the surface of the electrode and exhibiting better storage and electrochemical performance compared to conventional carbon based EDLC. 9 However, in the development of pseudocapacitive materials with theoretical specific capacitance, achieving flexibility and stability remains challenging but will yield more practical values on a commercial scale.…”

2D/2D g-C3N4/1T-MoS2 Nanohybrids as Schottky Heterojunction Photocatalysts for Nuclear Wastewater Pretreatment

“…Generally, the organic matter, especially TA, will chelate with nuclides (e.g., hexavalent uranium ions) in nuclear wastewater, which seriously reduces the water-soluble state and exchange state of such metal ions. This increases the difficulty of targeted removal of heavy metals via various methods such as physical adsorption, chemical fixation, etc. , Therefore, it is necessary to pretreat the organic matter in the nuclear wastewater and then remove the nuclides . It seems that photocatalytic technology has become a promising strategy for the treatment of the organic matter in nuclear wastewater due to its convenient operation and environmental friendliness. − However, the photocatalytic efficiency extremely depends on the physicochemical properties of the photocatalyst.…”

A Comprehensive Review of Graphitic Carbon Nitride (g-C3N4)–Metal Oxide-Based Nanocomposites: Potential for Photocatalysis and Sensing

“…Consequently, metal oxidebased g-C 3 N 4 nanocomposites can be used in different applications with enhanced electric, magnetic, and photocatalytic properties, such as H 2 generation, CO 2 reduction, NO oxidation, degradation of organic and inorganic dyes and other organic material, removal of toxic metal species, especially Cr (VI) from water, antibodies decontamination, solar cells, sensing, etc. [100][101][102][103][104]. In this part of the review, some metal oxide-based g-C 3 N 4 heterojunction structures are compared with the g-C 3 N 4 .…”

“…Like other heterojunctions, doping is another element to improve the performance of these composites and widen their applications [372][373][374][375][376]. Some g-C 3 N 4 -based ternary composites comprising the metal oxide compounds can promote photocatalytic activities [103,[377][378][379][380]. Bismuth complex oxides are among the most efficient catalysts with layered structures beside the g-C 3 N 4 -based composites.…”
