About this Research Topic
The environment has become a growing worldwide, along with the expansion and progress of science and technology. One of the major environmental issues is the contamination of organic and inorganic pollutants in wastewater. Carbon-based nanomaterials (CBNs) include carbon nanotubes, fullerenes, graphene and its derivatives, graphene oxide, activated carbon, nanodiamonds and carbon-based quantum dots. CBNs have great potential for the removal of organic and inorganic pollutants from water because of their nanosize, large surface area and easily modified through chemical functionalization. This Research Topic aims to highlight the importance of the application of CBNs in the treatment of organic and inorganic pollutants from wastewater using adsorption or catalysis.
Conventional technologies such as precipitation, oxidation, reverse osmosis, adsorption, membrane filtration, catalysis, coagulation, bio-remediation, advanced oxidation processes and etc. have been adopted to remove both organic and inorganic pollutants in wastewater. Some of the conventional treatments are found to be inconvenient as it requires a large operational area and extra chemical processes to remove the undesired sludge produced. Both adsorption and catalysis have gained great interest as nanotechnology for wastewater treatment due to their higher removal efficiency, lower operational cost and minimalism in design. However, it is a challenge to realize such techniques on an industrial scale and there are some areas where the technology could be further enhanced: high efficiency and high product yield design of CBNs, optimized operation conditions, and reactor design. It is also important to understand the underlying mechanism of adsorption and catalysis and to predict the performance of CBNs using computation methods.
We invite the submission of Original Research, Review, Mini Review, Perspective articles, covering recent advances in the design, synthesis, characterization and optimization of CBNs, as well as the application of CBNs for the removal of organic or inorganic pollutants by using adsorption and/or catalysis methods, such as photocatalysis, electrocatalysis and other catalytic oxidation. Areas of interest could include, but are not limited to:
• Design of CBNs with high quality, high efficiency and high product yield for the removal of organic or inorganic pollutant using catalysis and/or adsorption
• Design of reactor with high efficiency for abovementioned application work
• Functionalized CBNs and the combination of CBNs with other materials to form composites for the abovementioned application work
• Optimisation of application work by varying experimental condition and/or computational methods
• Explore the mechanism insights of the catalysis and/or adsorption process via experiments and/or computational methods.
