Effects of composition and nanostructuring of palladium selenide phases, Pd₄Se, Pd₇Se₄and Pd₁₇Se₁₅, on ORR activity and their use in Mg–air batteries

Abstract

The increasing demand for conversion and storage of energy has been the driving force for scientific pursuits towards developing novel, highly active and selective materials.

FeNi2Se4–Reduced Graphene Oxide Nanocomposite: Enhancing Bifunctional Electrocatalytic Activity for Oxygen Evolution and Reduction through Synergistic Effects

“…[60,61,62] Accordingly, the ORR catalytic activity of was lower than that of 5% Pt/C in alkaline medium (Figure S11), it is comparable to other selenide based ORR catalysts. [63,64] The kinetics of the ORR catalytic activity along with the number of electrons involved in the process were determined from Koutecky -Levich plots (K-L plots) as shown in Figure 7b. The linear and parallel behavior of the K-L plots at various potentials suggest idential electron transfer involved thourghout the ORR process and first order reduction kinetic with respect to dissove oxygen.…”

Catalytically active nanosized Pd9Te4(telluropalladinite) and PdTe (kotulskite) alloys: first precursor-architecture controlled synthesis using palladium complexes of organotellurium compounds as single source precursors

“…1 Composition, stability, size and shape are among those factors on which the physicochemical properties of nanomaterials have been found to depend. 1 In this regard, metal chalcogenide nanomaterials [1][2][3] have attracted the attention of researchers increasingly due to their various applications in energy conversion, storage and electronics, 2-5 development of materials for semiconductors, [6][7][8] dye-sensitized solar cells, 9,10 magnesium-air batteries, 11 aerogel fabrication, 12 and catalysis. [13][14][15][16][17][18][19][20] Among different metal chalcogenides reported in literature, signicant work has been done in recent past on the exploration and development of binary phases of tellurides of various metals (excluding palladium), mainly due to their potential application 2 in memory devices, photovoltaic cells, thermoelectrics, biochemical applications, semiconductors with enhanced thermoelectric properties in nanocomposites, photothermal therapy, thin lms and nanomaterials and catalysis.…”

Additive Manufacturing as a Means of Gas Sensor Development for Battery Health Monitoring

“…Previous reports claim that this 3D-approach will permit the assembly of multiple sensors through DIW for the precise sensing of specific vapors in various atmospheres, especially for battery safety. Thus, the development of a class of 3D [19,[24][25][26].…”
