Cow Dung Derived PdNPs@WO3 Porous Carbon Nanodiscs as Trifunctional Catalysts for Design of Zinc–Air Batteries and Overall Water Splitting

Abstract: The main motif of this work is to fabricate a highly efficient, economic, nanodisc shaped trifunctional electrocatalyst using a tungsten trioxide modified carbon nanosheet decorated with palladium nanoparticles. The beauty of this work is that a special carbon precursor is used for the synthesis of the electrocatalyst, a waste material, i.e., cow dung. The performance of the cow dung derived nanodisc electrocatalyst (Pd@WO3-NDs) toward oxygen evolution reaction (OER), oxygen reduction reaction (ORR), and hydro… Show more

“…Functionalities of carbon-based catalysts can be further enriched or synergistically enhanced through hybridizing with different types of metal oxides/sulfides/phosphides/nitrides. 55,[64][65][66][67][68][69][70][71][72] The perovskite lanthanum nickel oxide has been used as the electrocatalysts for the flexible ZAB, achieving a high volumetric energy density of 2905 Wh/L (based on the Zn film). 73 Hollow CoO nanoparticles were embedded into the N and S-doped porous carbon by pyrolysis of the organic-inorganic precursors.…”

“…[5,6] The OER pathway is the reverse of the oxygen reduction reaction (ORR).I nt he ORR process, O 2 is reduced into OH À or H 2 O, whereas in OER, H 2 Oi so xidized to O 2 ( Figure 2). [12] Some other reported catalysts have been based on Electrocatalysis is an efficient and promisingm eans of energy conversion,w ith minimal environmental footprint. For instance, the same electrode material with different facets can exhibit rather different reaction pathways andr esult in distinctly differentm echanisms.…”
