“…To do this, scientists created laminated stack nanofiltration membranes and modified g-C3N4, which serves as a support material in GO membranes, using GO nanosheets with abundant functional groups. This study establishes a novel standard for applying stable and dependable nanofiltration membranes in aquatic settings by demonstrating the efficacy of GO-modified g-C3N4 as an additive for creating innovative GO membranes [142].…”

Ilmenite is a mineral whose crystallinity can be altered by chemical treatment, producing TiO<sub>2</sub> and iron and titanium-based metal nanocomposites, which are applicable mainly for photocatalysis. Porous and crystalline biomass-derived carbon materials include graphene oxide, reduced graphene oxide, graphitic carbon nitride, catalytically graphitized sucrose and chitosan, and activated carbon. Ilmenite-based metal oxides coupled with biomass-based carbon materials are effective in environmental remediation, especially in dye photodegradation, adsorption, and antibacterial activity. This review summarizes the synthesis and applications of ilmenite and biomass-based composites nanomaterials.

Graphene is the main allotropy of carbon which exhibits properties like super conductivity, high electron transfer, and large surface area. Porous graphene (PG) has unique porous structure and many exposed edges. In 2D graphene pore ranges from several angstroms to nanometers. Similar to 3D graphene, which also has a porous structure, there are four different types: foam, sponge, and graphene hydrogel (GH). Graphene oxide (GO) and reduced graphene oxide (rGO) are used to create PG. This review focuses on various methods of synthesis of PG along with its inherent properties and methods to modify its properties by surface functionalization. Emphasis is also given on the discussion of various techniques that are involved in the PG characterization. This article discusses the formation of hybrids, and composites using PG. Applications and limitations of PG have also been indicated. This review shows an extensive overview of the main principles and the recent synthetic technologies about fabricating various innovative 3D graphene‐based materials. Subsequently, recent progresses in electrochemical energy devices and hydrogen energy generation/storage are explicitly covered. The applications of PG and its composites in the fields such as energy storage, solar units, sensors, supercapacitors, etc. have been discussed The up to date progress for pollutants detection and environmental remediation are also reviewed. Finally, challenges and outlooks in materials development for different applications are suggested.

“…Traditional NF membranes generally have low permeation flux, poor antifouling properties, short service life, and poor NaCl and dye separation performance, which also limit the development and application of NF membranes in dyeing wastewater treatment. 9 Thus, nanoparticles, such as ZnO/ y -FeOOH NP S , 10 GO, 11 sulfonated GO/ZnO nanocomposites, 12 and multiwall carbon nanotube (MWCNT), 13 were utilized to enhance the flux and antifouling properties of NF membranes. Nanoparticle modified NF membranes improved their rejection behavior for small organic molecules such as sulfamethoxazole, and some modified NF membranes exhibited photocatalytic properties in some degree.…”
