“…Both theoretical and experimental studies show that a hybrid structure of hBN and graphene can lead to unique and versatile materials with properties intermediate of these two and consequently have the potential to overcome the drawbacks of these individual materials in application purpose. [23][24][25][26][27] This fact is confirmed by the reported properties of BC 6 N . It has a moderate direct band gap (1.83 eV) 21,28 which is highly beneficial for optoelectronic application.…”

We explore the photocatalytic ability of honeycomb lattice of borocarbonitride, BC 6 N , investigating its opto-electronic properties and band-edge alignment based on hybrid density functional theory. We observe that along with pronounced visible absorbance, BC 6 N exhibits a good reducing ability. It is capable of depositing heavy metal ions, hydrogen fuel generation and carbon dioxide sequestration through photoelectrocatalysis. To broaden its applicability we further tune its redox ability using biaxial strain. We observe even a slight expansion makes this material capable of performing simultaneous oxidation and reduction, which is essential for waste management and hydrogen generation through spontaneous water splitting. In this study, we propose BC 6 N to be a promising potential candidate as metal free 2D photocatalyst and show ways to tune its applicability to address multiple environmental crises.

“…Disadvantages, such as embrittlement of the membrane because of low temperature phase transitions, can reduce the effectiveness of the membrane for large-scale operations. Mixed matrix membranes contain microstructures with inorganic material in the form of nanoparticles in a discrete phase, embedded in a continuous polymer matrix [43]. is concept combines the strong points of each stage: alluring mechanical properties, efficient interaction capacity of polymers, and high selectivity of the dispersed fillers.…”

The adoption of nanodoped membranes in the areas of gas stream separation, water, and wastewater treatments due to the physical and operational advantages of such membranes has significantly increased. The literature has shown that the surface structure and physicochemical properties of nanodoped membranes contribute significantly to the interaction and rejection characteristics when compared to bare membranes. This study reviews the recent developments on nanodoped membranes, and their hybrids for carbon capture and gas separation operations. Features such as the nanoparticles/materials and hybrids used for membrane doping and the effect of physicochemical properties and water vapour in nanodoped membrane performance for carbon capture are discussed. The highlights of this review show that nanodoped membrane is a facile modification technique which improves the membrane performance in most cases and holds a great potential for carbon capture. Membrane module design and material, thickness, structure, and configuration were identified as key factors that contribute directly, to nanodoped membrane performance. This study also affirms that the three core parameters satisfied before turning a microporous material into a membrane are as follows: high permeability and selectivity, ease of fabrication, and robust structure. From the findings, it is also observed that the application of smart models and knowledge-based systems have not been extensively studied in nanoparticle-/material-doped membranes. More studies are encouraged because technical improvements are needed in order to achieve high performance of carbon capture using nanodoped membranes, as well as improving their durability, permeability, and selectivity of the membrane.

“…24 Consequently, GeZn 1.7 ON 1.8 exhibits high conductivity and fast ionic diffusion than those of traditional metal nitrides, and its excellent structural and chemical stability also favor its usage in violent electrochemical reaction environments. 25 Therefore, GeZn 1.7 ON 1.8 is considered to be the promising alternative anode-active material with excellent structural stability in electrochemical reactions for the lithium-ion storage, which is even superior to the conventional metal nitride-based anode materials. However, when it comes to practical applications, issues such as unsatisfied lithium-ion transport kinetics and cycling capacity have been identified, which resulted from their insufficient conductance and active sites.…”
