The high performance NiFe layered double hydroxides@ Ti3C2Tx/reduced graphene oxide hybrid catalyst for oxygen evolution reaction

NiFe-LDH/MXene nano-array hybrid architecture for exceptional capacitive lithium storage

“…1b. 34,35 In addition, with the increase in MXene content, the (002) and (112) peaks of NiFe-LDH/MXene hybrid materials became more and more obvious, and the characteristic peaks belonging to NiFe-LDH did not change significantly. Moreover, compared with other hybrid materials, NiFe-LDH/MXene-500 had a sharper diffraction peak, indicating that the addition of MXene was beneficial for the nucleation and growth of NiFe-LDH arrays and improved the crystallinity of the material.…”

Investigating the Impact of the Washing Steps of Layered Double Hydroxides (LDH) on the Electrochemical Performance

“…They are currently attracting more technological interest due to their outstanding properties such as facile synthesis, unique structure, unvarying distribution of diverse metal cations in the brucite layer, surface hydroxyl groups, high tunability, intercalated anions with interlamellar spaces, excellent chemical stability, and the ability to intercalate diverse varieties of anions (inorganic, organic, biomolecules, and even genes) [ 3 ]. Due to its tunability, LDH is acclaimed in a variety of technological applications such as photoluminescence [ 4 ], sensors [ 5 ], drug delivery [ 6 ], cosmetics [ 7 ], antimicrobial materials [ 8 ], catalysts [ 9 ], and supercapacitors [ 10 ]. However, LDH is more applied for energy storage applications because of the synergistic effects of two or more metals involved during its preparation resulting in higher theoretical specific capacitance compared to single counterparts [ 11 ].…”

“…Nonetheless, the hydrothermal and solvothermal methods are currently also being applied [ 18 , 19 , 20 ]. Almost all the LDH materials, regardless of the targeted application, undergo the washing stage after the reaction is completed [ 4 , 5 , 9 , 11 ]. In most cases, deionised/distilled water and other solvents are involved during the washing process of LDH [ 3 , 9 , 12 , 21 ].…”

Ethanol is the most used solvent, along with deionised/distilled water for the washing of LDH compared to others [ 21 , 22 , 23 , 24 ], even though methanol was also reported as being used for the same purpose [ 25 ].…”

Two-dimensional Titanium Nitride as a Highly Active Electrocatalyst for Ammonia Production via NO Electroreduction

“…The high surface-to-volume ratio, thermal and electrical conductivity, mechanical flexibility, as well as low cost of 2D materials make them favorable catalysts in lots of energy conversion and storage applications (Deng et al, 2016;Fan et al, 2021;Siahrostami et al, 2016). Hexagonal boron nitride (h-BN) (Rafiq et al, 2022), transition metal dichalcogenides (TMDCs) (Pu et al, 2022;Hernandez Ruiz et al, 2022), graphitic carbon nitride (g-C 3 N 4 ) (Song et al, 2022), layered metal oxides (Wang et al, 2022), layered double hydroxides (LDHs) Zhu et al, 2022), metal-organic frameworks (MOFs) (Iqbal et al, 2022), covalent-organic frameworks (COFs) (Ahmed and Jhung, 2021), MXenes (Wu et al, 2021), black phosphorus (BP) (Li et al, 2022), noble metals , and polymers (Wang et al, 2018) are examples of 2D catalysts. They have been extensively studied as the potential substitutes for the precious metal catalysts in processes such as hydrogen evolution reaction (HER), oxygen evolution reaction (OER), electrocatalytic carbon dioxide reduction (ECR), N 2 reduction reaction (NRR), and NO electroreduction reaction (NOER) (Pu et al, 2022;Zhu et al, 2022;Khan et al, 2019;Ji et al, 2022;Zhang et al, 2021;Liu et al, 2021;Ji and Zhao, 2018;.…”
