Atomically thick two-dimensional materials have been increasingly attracting research interest not only due to their promising applications in a range of functional devices but also to their theoretical value to unraveling the catalytic electron transfer process within a simplified scenario. In this work, the monoatomic-thick dot-sized graphitic carbon nitride (g-C3N4) has been synthesized and ...

The adsorption behavior of hydrogen for synthesized graphitic carbon nitride (g-C3N4) and graphene oxide nanosheets was compared. The structure of the prepared g-C3N4 and graphene oxide samples were studied using TEM, FT-IR spectroscopy and surface area analysis. Textural results of the prepared nanosheets show that the surface area, total pore volume, and average internal diameter of g-C3N4 an...

The C3N4-tyrosinase (TYR) hybrid is a highly accurate, sensitive and simple fluorescent probe for the detection of dopamine (DOPA). Under optimized conditions, the relative fluorescence intensity of C3N4-TYR is proportional to the DOPA concentration in the range from 1 × 10(-3) to 3 × 10(-8) mol L(-1) with a correlation coefficient of 0.995. In the present system, the detection limit achieved i...

A polyoxoniobate/g-C3N4 nanoporous material with functional groups has been synthesized by using carbon nitride (g-C3N4) and hexaniobate (K8Nb6O19·10H2O, abbreviated as NbO) as precursors. The structure and compositions of the as-prepared nanomaterials were characterized by XRD, FT-IR, FESEM, TEM, and XPS. These two kinds of materials interact with each other forming a hybrid composite, which c...

The increasing concern about environmental pollution and fossil fuel energies have urged researchers to seek renewable energy sources and methods for pollutant decomposition. Photocatalysis seems to be one of the most promising approaches, which uses natural sunlight to produce hydrogen from water and removes organic pollutants from the environment. Among the various photocatalysts, graphitic c...

The key challenge for fabricating electrogenerated chemiluminescence (ECL) biosensors still lies in the improvement of the sensing performance of ECL luminophores. Graphite-like carbon nitride (g-C3N4) nanosheets were prepared and the cathodic ECL performance was investigated. The ECL emission of g-C3N4 nanosheets was greatly enhanced and higher sensing sensitivity towards copper ions was achie...

The as-prepared films are capable of convenient, sensitive, selective, rapid and recyclable sensing of Cu(2+) and Ag(+) in water and serum, indicating the sensor's potential application in disease diagnosis. Attractively, our sensor is able to differentiate Cu(2+) and Ag(+) by making use o...

Searching for effective approaches of accelerating charge separation and broadening optical absorption is critical for designing a high-performance photocatalytic system. Herein, a photocatalyst based on the non-metal group doped porous ultrathin g-C3N4 nanosheets (CNB NS) was prepared through a combined methodology of precursor reforming and thermal condensation. The synergistic effect of non-...

A low cost and non-precious metal composite material g-C3N4-LaNiO3 (CNL) was synthesized as a bifunctional electrocatalyst for the air electrode of lithium-oxygen (Li-O2) batteries. The composition strategy changed the electron structure of LaNiO3 and g-C3N4, ensures high Ni(3+)/Ni(2+) ratio and more absorbed hydroxyl on the surface of CNL that can promote the oxygen reduction reaction (ORR) an...

The interfacial effect on the structural, electronic and optical properties of a hybrid triazine-based graphitic carbon nitride and graphene nanocomposite is calculated using the first-principles method. It reveals the favorable stacking pattern utilizing the ab initio thermodynamics approach. The electronic band structure presents that the high carrier mobility is maintained in a hybrid g-CN/G...
