“…This feature has facilitated the accelerated degradation of organic pollutants [ 12 , 13 ]. Consequently, AOPs have gained prominence and have become preferred alternatives over traditional water treatment methods, due to their remarkable success in effectively degrading organic pollutants [ 14 ]. Among the various AOP methods, photocatalysis and its various adaptations have emerged as the most promising technique for industrial applications [ 13 ].…”

Especially, photocatalytic technology provides a new perspective to address this increasingly severe problem (He et al 2023; Roy et al 2023). Photocatalytic degradation is a method that utilizes light energy to stimulate catalysts and convert organic substances into non-toxic or low-toxic products (Abdurahman et al 2021).…”

Graphitic carbon nitride (g-C3N4) is a fresh type of environmentally friendly photocatalytic material with the potential to degrade pollutants in water. In particular, g-C3N4 (CN) has significant characteristics in the treatment of antibiotics, which has attracted extensive attention from researchers. However, due to the less active sites and fast carrier recombination rate resulting from the block morphology, the CN has unsatisfactory photocatalytic performance up to now. Therefore, in this paper, a thinner and smaller CN nanosheets with more active sites and slower carrier recombination rate were successfully prepared by a combination of P element doping and triple calcination modifications. The modified 1.5% P-CN-3 not only has a 2.24-fold increase in the degradation ability of antibiotic Tetracycline (TC) compared to pure CN, but also has a hydrogen production rate of 2268.27 µmol·g− 1·h− 1 for water decomposition. This paper provides an effective approach for the modification of CN.

Nanocellulose (NC)/graphene oxide (GO) composites are attractive materials with a range of unique features obtained from the integration of NC and GO. These materials have high potential use in various sectors such as biomedicine, wastewater remediation, sensor/biosensor technology, and energy storage/conversion. The simple functionalization and modification of NC or GO afford an opportunity for tailoring these materials for anticipated applications. In wastewater treatment applications, they can be employed as reliable adsorbents for the removal of different pollutants, such as metals, dyes, oils, and pesticides as well as sensors for the detection and monitoring of these pollutants. Besides that, NC/GO composites can be applied as catalysts for catalytic degradation for a wide variety of pollutants. These materials have been also reported to be applicable in biomedical applications such as drug delivery, antibacterial and biosensing. Energy storage applications such as supercapacitors NC/GO-based materials were also utilized. This review summarizes NC/GO hybrid fabrication, characterization, and their application in different fields, i.e. sensing, energy storage, and wastewater remediation. It also covered a broad overview of the status of integrating GO with nanocellulose materials, i.e. bacterial cellulose, cellulose nanofibrils, and cellulose nanocrystals. We concluded with the challenges and outlook for NC/GO-based composites.
