During their lifetime, the electrocatalytically active NiFe LDH platelets show impressive, but unstable water-splitting capabilities due largely to compositional degradation.
Abstract Very recently, it has been reported that mixed transition metal oxide (TMO)/MXene catalysts show improved performance over TMO only for the oxygen evolution reaction (OER). However, reasoning behind this observation is unknown. In work Co(OH) 2 /Ti 3 C T x were prepared and characterized OER using ex situ operando spectroscopy techniques in order to initiate understanding of why TMO/MXene materials better performances compared catalysts. This shows electrocatalysis composite...
This paper describes the wet-chemistry synthesis of highly crystalline hexagonal flakes Ni-Fe layered double hydroxide (LDH) produced at temperature as low 100 °C. The with diameter in range 0.5-1.5 μm and thickness between 15 20 nm were obtained by homogeneous precipitation method use triethanolamine (TEA) urea. By analyzing intermediate products, it is suggested that, differently from previous reports, a thermodynamically metastable iron oxyhydroxide Ni-TEA complex are firstly formed room...
MXenes are a class of 2D/layered materials which highly conductive, hydrophilic, have large electrochemical surface area and easily processible into electrodes for energy applications. Since the discovery over ten years ago, these been mainly used in preparation batteries supercapacitors. However, due to their aforementioned properties, could potentially be utilised as component catalyst layer Oxygen Evolution Reaction (OER). This opinion piece will discuss some recent literature hybrid...
Abstract Nickel–iron-layered double hydroxide (NiFe LDH) platelets with high morphological regularity and submicrometre lateral dimensions were synthesized using a homogeneous precipitation technique for highly efficient catalysis of the oxygen evolution reaction (OER). Considering edge sites are point activity, efforts made to control platelet size within dispersions. The goal is controllably isolate characterize size-reduced NiFe LDH particles. Synthetic approaches have not been...
This paper describes the wet-chemistry synthesis of highly crystalline hexagonal flakes Ni-Fe layered double hydroxide (LDH) produced at temperature as low 100 oC. The with diameter in range 0.5-1.5 um and thickness between 15 20 nm were obtained by homogeneous precipitation method use triethanolamine (TEA) urea. By analyzing intermediate products, it is suggested that, differently from previous reports, a thermodynamically metastable iron oxyhydroxide Ni-TEA complex are firstly formed room...
The oxygen evolution reaction (OER) has drawn significant interest in the field of renewable and sustainable energy recent years, with potential applications for hybrid electric vehicles (HEV) form hydrogen fuel cells metal-air batteries, among others. Perhaps most feature OER is fact that it a necessary ‘step’ H 2 gas by water electrolysis, bringing an associated (E ≈ 1.23 V). To overcome this barrier minimum overpoetential (η), effective electrocatalyst required to facilitate reaction....
Currently, approximately 96% of global H 2 production is carried out by fossil fuel based routes such as steam reforming natural gas or coal gasification; 1 while only 4% generated renewable energy water splitting. To increase the percentage produced splitting, it necessary to lower overall cost and, at same time, improve efficiency associated with splitting technologies, which is, closely related cost, durability and kinetic issues arising from catalysts used. Water also known electrolysis,...
