Zinc-telluride nanospheres as an efficient water oxidation electrocatalyst displaying a low overpotential for oxygen evolution

Abstract

Electrochemical water splitting is economically unviable due to the sluggish kinetics of the anodically uphill oxygen evolution reaction (OER).

Metalloid Te‐Doped Fe‐Based Catalysts Applied for Electrochemical Water Oxidation

“…According to the literature, [19] benefiting from its good electrical conductivity, high covalence, and low electronegativity, Te can increase the covalency and decrease the electronegativity of the anionic network around the transition metal center, further lead to an improvement in catalytic efficiency. Thus, we speculate that this is why the ED‐FeTe x catalysts show better performance than CVD‐FeTe x catalysts toward the OER [19–21] …”

“…etc.) have been studied and exhibited great electrocatalytic activity in alkaline solutions [19–23] . Meanwhile, Fe‐based catalysts have broad application prospects due to their cheap and non‐toxic characteristics.…”

“…have been studied and exhibited great electrocatalytic activity in alkaline solutions. [19][20][21][22][23] Meanwhile, Fe-based catalysts have broad application prospects due to their cheap and non-toxic characteristics. Besides, the intrinsic semiconductor/metal characters and unique electronic structures of iron-based catalysts endow them with excellent performance.…”

“…Thus, we speculate that this is why the ED-FeTe x catalysts show better performance than CVD-FeTe x catalysts toward the OER. [19][20][21] The morphology of ED-FeTe x and CVD-FeTe x catalysts were characterized by scanning electron microscopy (SEM). The SEM images of ED-FeTe x (Figure 2a-c) show that the surface is mainly composed of randomly oriented nanosheets which are not completely perpendicular to the metal substrate, but crosslinked with each other.…”

Electrochemical sensing platform for the simultaneous femtomolar detection of amlodipine and atorvastatin drugs

“…whereas, E (Ag NPs drug) , E (COOH-CNTs-Ag NPs-drug) and E (fCNTs-Ag NPs-fCNTs-drug) are the total adsorption energies of the drug/modier merged structures while, E COOH-CNTs , E Ag NPs , E NH2-CNTs , E Ag NPs , and E drug are the individual structure energies. 28…”
