Title: Ni_xWO_2.72 nanorods as an efficient electrocatalyst for oxygen evolution reaction

Abstract

Ni_xWO_2.72 nanorods (NRs) are synthesized by a one-pot reaction of Ni(acac)₂ and WCl₄. In the rod structure, Ni(II) intercalates in the defective perovskite-type WO_2.72 and is stabilized. The Ni_xWO_2.72 NRs show the x-dependent electrocatalysis for the oxygen evolution reaction (OER) in 0.1M KOH with Ni_0.78WO_2.72 being the most efficient, even outperforming the commercial Ir-catalyst. Lastly, the synthesis is not limited to Ni_xWO_2.72 but can be extended to M_xWO_2.72 (M = Co, Fe) as well, providing a new class of oxide-based catalysts for efficient OER and other energy conversion reactions.

Pd Nanoparticles Coupled to WO_2.72 Nanorods for Enhanced Electrochemical Oxidation of Formic Acid

Journal Article Xi, Zheng ; Erdosy, Daniel P. ; Mendoza-Garcia, Adriana ; ... - Nano Letters

In this work, we synthesize a new type of hybrid Pd/WO_2.72 structure with 5 nm Pd nanoparticles (NPs) anchored on 50 × 5 nm WO_2.72 nanorods. The strong Pd/WO_2.72 coupling results in the lattice expansion of Pd from 0.23 to 0.27 nm and the decrease of Pd surface electron density. As a result, the Pd/WO_2.72 shows much enhanced catalysis toward electrochemical oxidation of formic acid in 0.1 M HClO₄; it has a mass activity of ~1600 mA/mg_Pd in a broad potential range of 0.4–0.85 V (vs RHE) and shows no obvious activity loss after a 12 h chronoamperometry test atmore »« less

Stabilizing CuPd Nanoparticles via CuPd Coupling to WO_2.72 Nanorods in Electrochemical Oxidation of Formic Acid

Journal Article Xi, Zheng ; Li, Junrui ; Su, Dong ; ... - Journal of the American Chemical Society

Stabilizing a 3d-transition metal component M from an MPd alloy structure in an acidic environment is key to the enhancement of MPd catalysis for various reactions. Here we show a strategy to stabilize Cu in 5 nm CuPd nanoparticles (NPs) by coupling the CuPd NPs with perovskite-type WO_2.72 nanorods (NRs). The CuPd NPs are prepared by controlled diffusion of Cu into Pd NPs and the coupled CuPd/WO_2.72 are synthesized by growing WO_2.72 NRs in the presence of CuPd NPs. The CuPd/WO_2.72 can stabilize Cu in 0.1 M HClO4 solution and, as a result, they show Cu, Pd composition dependent activitymore »« less

RuO 2 nanoparticles supported on MnO 2 nanorods as high efficient bifunctional electrocatalyst of lithium-oxygen battery

Journal Article Xu, Yue-Feng ; Chen, Yuan ; Xu, Gui-Liang ; ... - Nano Energy

RuO2 nanoparticles supported on MnO2 nanorods (denoted as np-RuO2/nr-MnO2) were synthesized via a two-step hydrothermal reaction. SEM and TEM images both illustrated that RuO2 nanoparticles are well dispersed on the surface of MnO2 nanorods in the as-prepared np-RuO2/nr-MnO2 material. Electrochemical results demonstrated that the np-RuO2/nr-MnO2 as oxygen cathode of Li-O-2 batteries could maintain a reversible capacity of 500 mA h g(-1) within 75 cycles at a rate of 50 mA g(-1), and a higher capacity of 4000 mA h g(-1) within 20 cycles at a rate as high as 200 mA g(-1).

Interfacial Engineering of W ₂ N/WC Heterostructures Derived from Solid‐State Synthesis: A Highly Efficient Trifunctional Electrocatalyst for ORR, OER, and HER

Journal Article Diao, Jinxiang ; Qiu, Yu ; Liu, Shuangquan ; ... - Advanced Materials

Abstract To meet the practical demand of overall water splitting and regenerative metal–air batteries, highly efficient, low‐cost, and durable electrocatalysts for the oxygen reduction reaction (ORR), oxygen evolution reaction (OER), and hydrogen evolution reaction (HER) are required to displace noble metal catalysts. In this work, a facile solid‐state synthesis strategy is developed to construct the interfacial engineering of W ₂ N/WC heterostructures, in which abundant interfaces are formed. Under high temperature (800 °C), volatile CN _x species from dicyanodiamide are trapped by WO ₃ nanorods, followed by simultaneous nitridation and carbonization, to form W ₂ N/WC heterostructure catalysts. The resultantmore »« less

Highlights: • Ag{sub 2}WO{sub 4}/AgX hybrid nanorods were prepared by a facile in-situ anion exchange reaction. • Ag{sub 2}WO{sub 4} nanorods and different X{sup −} ions were reacted in water at room temperature. • The hybrids possess significantly enhanced photoelectrochemical properties. • Ag{sub 2}WO{sub 4}/AgBr hybrids exhibit the highest photocatalytic activity among three samples. • The active species tests were also investigated to confirm photocatalytic mechanism. - Abstract: In this work, we demonstrated a general strategy for the preparation of a series of uniform Ag{sub 2}WO{sub 4}/AgX (X = Cl, Br, I) hybrid nanorods by a facile in-situ anion exchangemore »« less
