Tip effect assisted high active sites for oxygen evolution reaction tuned using transition metals (Cr, Fe and Mo) doped with CoP

Abstract

Tip effect of the high curvature tip top can cause the electromagnetic effects to improve the catalytic performance. Transition metals (Cr, Fe and Mo) doping into CoP array nanocones alters...

Bamboo-like nitrogen-doped carbon supported chlorine-doped Fe2P as an antibacterial oxygen reduction catalyst

“…2d). 21 The Cl 2p spectrum could be decomposed into Cl 2p 3/2 , Cl 2p 1/2 and satellite peaks. The characteristic peaks of Cl 2p 3/2 (200.19 eV), Cl 2p 1/2 (197.67 eV) and the satellite peaks (199.29 eV) could be identified in the Cl 2p spectrum of Cl-Fe 2 P/NC (Fig.…”

Theoretical and Experimental Aspects of Electrocatalysts for Oxygen Evolution Reaction

“…[74,75] The generalized electronic descriptor (upper-bond d band central, e W d ) is defined to illustrate the discrepancies. It can be described as Equation (10).…”

“…Transition metal-based catalysts that are expected to replace precious metals are currently hot and difficult issues in the field of OER development. [10][11][12][13][14][15][16][17] Recently, the strategies to improve the OER catalytic performance can be divided into the following categories: structure and morphology regulation, [18][19][20] vacancy and defect construction, [21][22][23][24] and surface and interface modification. [25,26] Nevertheless, the investigations on preparation strategies and catalytic mechanisms are still insufficient to support the rational design of advanced OER catalysts.…”

“…These shortcomings severely limit the efficiency of hydrogen production through water electrolysis. Transition metal‐based catalysts that are expected to replace precious metals are currently hot and difficult issues in the field of OER development [10–17] . Recently, the strategies to improve the OER catalytic performance can be divided into the following categories: structure and morphology regulation, [18–20] vacancy and defect construction, [21–24] and surface and interface modification [25,26] .…”
