Boron Nitride doped Chitosan Functionalized Graphene for an Efficient Dye Degradation

Abstract

In this article, we have developed a simple and highly effective method for synthesis of boron nitride, chitosan and graphenebased composite (BNCG). The BNCG has been synthesized by using cheap precursors such as boric acid, melamine, chitosan, and graphene oxide in a seal tube under nitrogen atmosphere and applied to degrade methylene blue. The dye degradation of methylene blue (MB) and Acid orange II (AO II) has been carried out using sunlight. The effective degradation of dye takes place at basic pH. The 10, 25, and 50 ppm of dye has successfully degraded in 10 min. of time. The degradation study concluded that about 87 % of the MB and 57 % AO II dye were degraded by BNCG composite. The degradation follows the first order kinetics as per the observed results. This preparative method and BNCG composite will overcome complicated preparative steps and a long time for dye degradation.

Facile Preparation of MgO Nanoparticles by Microwave‐Assisted Sol‐Gel Hydrothermal Method towards the Paraoxon Pollutants Degradation

“…Several metal/non-metal oxides and their composites have been utilized to decompose organic dye pollutants into harmless degradation products, i. e., TiO 2 , [3,4] Graphene@PANI-Fe 3 O 4 , [5] boron nitride@CS [6,7] with merits of simple operation, mild reaction conditions, and high dye degradation efficiency.…”

Removal of Congo Red From Water By Adsorption Onto Chitosan-BN-Fe2O3: Kinetic and Isotherm Studies

“…However, in this study, congo red was not removed and Fe2O3 was not added. Therefore, this study is unique in the literatüre [22]. Investigated were the effects of this produced adsorbent on congo red removal in various parameters.…”
