ABSTRACT. In this paper, a carbon nitride Ag hybrid nanocomposite is synthesized. Carbon nitride Ag hybrid nanocomposite was synthesized by chemical oxidative polymerization method. The hybrid was characterized by UVVisible spectroscopy, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and field emission scanning electron microscopy (FE-SEM). The electrochemical oxidation of hydroquinone was inspected by cyclic voltammetry (CV). The Carbon nitride Ag hybrid modified GCE (hybrid nanocomposite /GCE) showed enhanced electrocatalytic oxidation of hydroquinone than GCE. The hybrid showed better photoccatalytic degradation of methylene blue within 180 mins.

Introduction. Diverse polymeric carbon nitrides, which differ in their atomic sizes, have been reported by thermal condensation of organic monomers. One of the most applicable is the polymeric form melon, H3C6N9, a major architecture which is a significance of an incomplete condensation of carbon nitride precursors. [1] Bojdys et al. reduce the hydrogen contented to a sensible C3N4 formulation by condensation of dicyandiamide in a salt melt of lithium and potassium chloride [2]. The results designate that graphitic allotropes are the most stable phases under ambient situations for the C3N4 composition. Carbon nitrides and connected compounds are of great engineering attention as possible materials for microelectronic devices, optical, magnetic and tri bological applications [3, [4], [5], [6]. Graphitic carbon nitrides container also be an energetic support, Lewis-base character, for the dispersal of metal particles in heterogeneous catalysis. [10] Recently, Wang et al. have measured g-C3N4 as a plentiful photocatalyst for hydrogen construction from water [11]. In adding to mentioned perspectives, in the past decades, studies on the most stable polymorphs of C3 N4 were interested by a special attention for the synthesis of new low-compressible materials [12], [13]. Synthesis of carbon nitride-Ag hybrid nanocomposite. The graphitic C3N4-silver hybrid nanocomposites were synthesized using urea-silver acetate poly-condensation methods. In 95:5% amounts of urea- silver acetate were taken in alumina crucibles with covered and calcined at 550 o C for 5 h at a heating rate of 50 C min -1. Result and Dissuasion UV-Visible spectroscopy. The UV-Visible absorption spectrum of the silver- carbon nitride nanocomposite is showed in Fig. 1. The broad peaks in the range of 600 nm were corresponding to -Visible absorption spectrum of the silver nanoparticles is one broad peak in the range of 410 nm. The result 6
