Using BCN nanostructure as anode electrode for photoelectrocatalytic degradation of organics: a statistical approach

Abstract

In this study, boron carbon nitride (BCN) nanostructures were used as photocatalyst which was synthesized in a chemical vapor deposition reactor. Photoelectrocatalysis was used for degradation organic pollutants from produced water. BCN nanostructures were coated on a coil-type copper wire to be as anode electrode in the photoelectrocatalytic process. The effect of different parameters on chemical oxygen demand (COD) removal efficiency from produced water was investigated by a central composite design (CCD) to maximize photoelectrocatalysis influence as one of the most used methods of wastewater treatment. A 12 run Plackett–Burman design was used for screening of the parameters (initial COD, electrical conductivity, applied cell voltage, UV lamp wavelength, H2O2 concentration, residence time, and initial pH) which led to the selection of residence time and initial pH as effective parameters. Since the core goal of this study was to maximize the COD removal efficiency, the steepest ascent method was used to propel these two parameters to the optimum region. Finally, CCD showed that applying photoelectrocatalysis could lead to 88.79% of the COD removal efficiency which would be an optimum value at a residence time of 15.85 min and a pH value of 3.3. Ultimately, this result was confirmed by experimentation at those conditions.

Boron Carbon Nitride-Assisted Electro-Functionalization of Screen-Printed Electrode for Tryptophan Sensing

“…Evidently, the material showcases a distinct and sharp peak at 2θ = 27.97°, which corresponds to the (002) plane of BCN. 24 The peak is in agreement with the previously reported literature, 25 confirming the formation of BCN. Nevertheless, the presence of melamine diborate 26 was also indicated from the XRD patterns.…”

“…The intense peaks in the recorded diffractogram clearly indicate the high crystallinity of the prepared material. Evidently, the material showcases a distinct and sharp peak at 2θ = 27.97°, which corresponds to the (002) plane of BCN . The peak is in agreement with the previously reported literature, confirming the formation of BCN.…”

Recent insights into BCN nanomaterials – synthesis, properties and applications

“…Nanotubes, nanorods and nanoribbons are 1D BCN nanomaterials, among which BCN nanotubes (BCNNTs) have gained utmost interest. 75–77 Similar to BNNTs and carbon nanotubes (CNTs), BCNNTs exhibit spiral or bamboo-like conformations wrapped in single-walled or multi-walled structure. A distinction from CNTs and BNNTs is that BCNNTs exhibit tunable electrical and optical properties with variation in B, C, and N atoms’ arrangement and composition.…”
