One-step synthesis of boron nitride carbon nanosheets containing zinc oxide for catalysis of the oxygen reduction reaction and degradation of organic dyes

Abstract

Boron nitride carbon sheets containing zinc oxide (ZnO/h-BNC) with a hexagonal B–N bond structure were synthesized by a one-step thermal treatment, and investigated for catalysis of oxygen reduction reaction and degradation of organic dye.

Gamma Ray Irradiation Enhances the Linkage of Cotton Fabrics Coated with ZnO Nanoparticles

“…to 1021.6 eV due to the removal of NO x , oxygen, and other intermediate products formed during the formation of ZnO hybrid boron nitride structures. 39 Yet, compared to Yamuna and co-workers' work, the necessity of annealing at a high temperature can be replaced by gamma ray exposure to gain higher B.E. In our case, irradiation results in the shift of B.E.…”

“…of around 5.4 eV (i.e., at 1027 eV) at 300 °C; however, annealing at 500 °C resulted in the large shift of B.E. to 1021.6 eV due to the removal of NO x , oxygen, and other intermediate products formed during the formation of ZnO hybrid boron nitride structures . Yet, compared to Yamuna and co-workers’ work, the necessity of annealing at a high temperature can be replaced by gamma ray exposure to gain higher B.E.…”

Hierarchical oxygen reduction reaction electrocatalysts based on FeSn0.5 species embedded in carbon nitride-graphene based supports

“…The typical "Pt-free" EC consists of a carbonaceous matrix, that coordinates species based on Earthabundant metals (e.g., Fe [13,17], Co [18,19], W [20], Zn [21]) through one or more type of heteroatoms such as B [21], N [17] and S [22], among many others [23]. A multitude of variations exist on this basic theme: in some instances it is claimed that the EC does not include any metal [24]; in others, the EC does not comprise a carbonaceous matrix [25,26].…”

Design of 3D WO3/h-BN nanocomposites for efficient visible-light-driven photocatalysis

“…36,37 Therefore, 2D BN nanosheets with tunable band structure can achieve an optimized band alignment with the photocatalyst, which offer a unique opportunity to overcome the easy recombination rate of the photo-generated electron-hole pairs, serving as the high photo-generated carrier transport way for high-performance degradation toward the target pollutants. BN modied Ag 3 VO 4 , 36 ZnO, 38 and CdS 39 were designed with an enlarged interaction on the curled BN surface and demonstrated a efficient charge transfer and separation processes between BN and the semiconductor, enhancing the corresponding photocatalytic activity. More interestingly, Weng et al 40 found that band gaps of BN could be tuned by chemically functionalized (002) plane edges, which exhibited widespectrum light absorptions in both UV and visible light ranges, acting as an inorganic sensitizer to induce the visible light response of TiO 2 for a high level of photocatalytic activity toward oxidative decomposition.…”
