Objective: With the increasing incidence of cancer and the dramatic effect of early detection on treatment and increase patient's life, many efforts have been devoted to making sensitive diagnosis systems. DNA as a biomarker for diagnosis of different types of cancers at the early stages of illness has attracted much attention.Methods: In this research novel electrochemical biosensor was ...

In recent years, two-dimensional (2D) graphitic carbon nitride (g-C3N4) has elicited interdisciplinary research fascination among the scientific communities due to its attractive properties such as appropriate band structures, visible-light absorption, and high chemical and thermal stability. At present, research aiming at engineering 2D g-C3N4 photocatalysts at an atomic and molecular level in...

Two types of photocatalysts, 1%Pt/Cd1?xZnxS/g-C3N4 (x = 0.2–0.3) and Cd1?xZnxS/1%Pt/g-C3N4 0.2–0.3), were synthesized by varying the deposition order platinum, a solid solution cadmium zinc sulfides onto surface g-C3N4. The characterization photocatalysts showed that, for 1%Pt/Cd1?xZnxS/g-C3N4, small platinum particles deposited sulfides; in case Cd1?xZnxS/1%Pt/g-C3N4, enlarged clusters located...

Successful synthesis of the stable metal-free two-dimensional polymer graphitic carbon-nitride with remarkable properties has made it as one of the most promising nanostructures in many novel nanodevices, especially photocatalytic ones. Understanding the mechanical properties of nanostructures is of crucial importance. Thus, this study employs density functional theory (DFT) to obtain the mecha...

A porous hybrid g-C3N4/RGO (CNRG) material has been fabricated through a facile hydrothermal process with the help of glucose molecules, and serves as an efficient immobilization substrate to support ultrathin Ni(OH)2 nanosheets under an easy precipitation process. It was found that the g-C3N4 flakes can uniformly coat on both sides of the RGO, forming sandwich-type composites with a hierarchic...

In this study, novel photocatalysts MVO4/g-C3N4 (M = La, Gd) were prepared by the hydrothermal method, through which different loading amounts of 10–50%MVO4 and g-C3N4 mixed ultrasonically oscillated to gain heterojunction catalysts. All samples characterized XRD, SEM, TEM, FT-IR, XPS, Us-vis, PL ensure successful integration LaVO4 GdVO4 with g-C3N4. The obtained results showed that could effec...

A novel, multi-walled carbon nanotubes (CNT) modified white C3N4 composite (CNT/white C3N4) with enhanced visible-light-response photoactivity was prepared. The white C3N4 and CNT combined together and formed the CNT/white C3N4 composite due to electrostatically-driven self-assembly with the hydrothermal method. The as-prepared white C3N4 and CNT/white C3N4 composite photocatalyst were characte...

A one-dimensional (1D) nanostructure having a porous network is an exceptional photocatalytic material to generate hydrogen (H2) and decontaminate wastewater using solar energy. In this report, we synthesized nanoporous 1D microrods of graphitic carbon nitride (g-C3N4) via a facile and template-free chemical approach at room temperature. The use of concentrated acids induced etching and lift-of...

The development of high catalytic performance heterogeneous catalysts such as peroxymonosulfate (PMS) activators is important for the practical remediation organic pollution caused by Rhodamine B (RhB). An economical and facile synthesized composite copper–magnesium oxide carbon nitride (CM/g-C3N4) was prepared sol-gel/high-temperature pyrolysis method to activate PMS RhB degradation. CM/g-C3N4...
