Synergistic Enhancement of Water-Splitting Performance Using MOF-Derived Ceria-Modified g-CN Nanocomposites: Synthesis, Performance Evaluation, and Stability Prediction with Machine Learning.

Diminishing the charge recombination rate by improving the photoelectrochemical (PEC) performance of graphitic carbon nitride (g-CN) is essential for better water oxidation. In this concern, this research explores the competent approach to enhance the PEC performance of g-CN nanosheets (NSs), creating their nanocomposites (NCs) with metal-organic framework (MOF)-derived porous CeO nanobars (NBs) along with ZnO nanorods (NRs) and TiO nanoparticles (NPs). The synthesis involved preparing CeO NBs and g-CN NSs through the calcination of respective precursors, while the sol-gel method is employed for ZnO NRs and TiO NPs.

Emerging Graphitic Carbon Nitride-based Nanobiomaterials for Biological Applications.

Graphitic carbon nitride (g-CN) based nanostructures are distinctive materials with unique compositional, structural, optical, and electronic properties with exceptional band structure, moderate surface area, and exceptional thermal and chemical stability. Because of these properties, g-CN based nanomaterials have shown promising applications and higher performance in the biological avenue. This review covers the state-of-the-art synthetic strategies used for the preparation of the materials, the basic structure, and a panorama of different optimization strategies leading to improved physicochemical properties responsible for the biological application.

Self-Assembled Synthesis of Porous Iron-Doped Graphitic Carbon Nitride Nanostructures for Efficient Photocatalytic Hydrogen Evolution and Nitrogen Fixation.

In this study, Fe-doped graphitic carbon nitride (Fe-MCNC) with varying Fe contents was synthesized via a supramolecular approach, followed by thermal exfoliation, and was then used for accelerated photocatalytic hydrogen evolution and nitrogen fixation. Various techniques were used to study the physicochemical properties of the MCN (g-CN from melamine) and Fe-MCNC (MCN for g-CN and C for cyanuric acid) catalysts. The field emission scanning electron microscopy (FE-SEM) images clearly demonstrate that the morphology of Fe-MCNC changes from planar sheets to porous, partially twisted (partially developed nanotube and nanorod) nanostructures.

Phase transformation and room temperature stabilization of various BiO nano-polymorphs: effect of oxygen-vacancy defects and reduced surface energy due to adsorbed carbon species.

We report the grain growth from the nanoscale to microscale and a transformation sequence from Bi →β-BiO→γ-BiO→α-BiO with the increase of annealing temperature. The room temperature (RT) stabilization of β-BiO nanoparticles (NPs) was attributed to the effect of reduced surface energy due to adsorbed carbon species, and oxygen vacancy defects may have played a significant role in the RT stabilization of γ-BiO NPs. An enhanced red emission band was evident from all the samples attributed to oxygen-vacancy defects formed during the growth process in contrast with the observed white emission band from the air annealed Bi ingots.

Ag Nanoparticles Connected to the Surface of TiO Electrostatically for Antibacterial Photoinactivation Studies.

Supported silver nanoparticles (Ag NPs) were prepared by chemical reduction method with a sol-gel method.
