Boron-doped graphene-supported manganese oxide nanotubes as an efficient non-metal catalyst for the oxygen reduction reaction

Abstract

An efficient, low cost and non-precious hybrid metal catalyst compound consisting of boron-doped graphene nanosheets (BGNSs) and manganese oxide (MnO2) nanotubes is used as a catalyst for the oxygen reduction reaction (ORR).

Reduced Graphene Oxide/Copper Nanoparticle Composites as Electrochemical Sensor Materials for Nitrate Detection

“…15 The three deconvoluted peaks of rGO centered at 285.9, 286.8, and 288.8 eV are attributed to the C−O hydroxyl group, CO, and O−CO carbonyl bond, respectively. 13 Figure 3c depicts the O 1s spectrum of the Cu-rGO-2 composite. The two deconvoluted peaks centered at 530.4 and 530.9 eV are attributed to Cu 2 O and Cu(OH) 2 , respectively.…”

“…Reduced graphene oxide (rGO), a two-dimensional (2D) nanosheet with sp 2 hybridized networks of carbon atoms, has recently emerged as an attractive material that possesses extraordinary physical and chemical properties, including excellent thermal and electrical conductivities, high chemical stability, rapid charge carrier mobility, and high surface area . Decoration with Cu nanostructures on the surface of rGO nanosheets in the Cu-rGO composite leads to an improvement in the catalytic activity of the composite toward NO 3 – reduction because of the enhancement of the composite’s conductivity and specific surface area after the incorporation of rGO.…”

Superior photoelectrocatalytic performance of ternary structural BiVO4/GQD/g-C3N4 heterojunction

“…Similarly, the protocols for measuring the surface formation energy and electrostatic potentials were included in our previous reports [16,22,23]. Meanwhile, in the case of RGO, GQDs, and g-C3N4, we used a single layer structure for the aforementioned analysis.…”

“…[15] In particular, carbon-based two-dimensional structures have garnered the most interest as they are capable of delivering excellent electrical conductivity: a highly desirable trait for a fuel cell electrocatalyst. [16,17] Recent investigations have demonstrated that boron/nitrogen/phosphorous/sulphur doped graphene [18][19][20][21] /graphene composites [22,23] /defect graphene [24,25] / graphitic carbon nitride [26] etc. hold great prospects as cathode materials in electrocatalysis.…”
