Abstract Graphitic carbon nitrides (g-C3N4s) have continued to attract attention as metal-free, low-cost semiconductor catalysts. Herein, a systematic synthesis and characterization of g-C3N4s prepared using four conventional precursors (urea (U), dicyandiamide (DCDA), semicarbazide hydrochloride (SC-HCl), thiosemicarbazide (TSC)) an unexplored one (thiosemicarbazide (TSC-HCl)) is presented. Eq...

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 ...

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...

Copper-based zeolite catalysts are widely used in methanol synthesis from methane oxidation, but their photothermal catalytic properties have seldom been explored. This study examines the effect of preparation method on Cu-based composite graphite-phase carbon nitride (Cu-MOR/g-C3N4) for direct oxidation by catalysis. Four different methods employed: liquid phase ion exchange (Cu-MOR/g-C3N4-IE)...

Hydrogen is a great sourcez of energy due to having zero emission carbon-based contents. It found primarily in water, which abundant and renewable. For electrochemical splitting water molecules, it necessary use catalytic materials that minimize consumption. As famous carbon material, graphitic nitride, with its excellent physicochemical properties diversified functionalities, presents potentia...

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...

An efficient membrane for helium separation from natural gas is quite crucial for cryogenic industries. However, most experimentally available membranes fail in separating helium from small molecules in natural gas, such as H2, as well as in 3He/4He isotopes separation. Using first-principles calculations, we theoretically demonstrated that the already-synthesized graphitic carbon nitride (g-C3...
