“…Both types of catalyst execute asymmetric addition of cyclohexanone 137 with N-PMP-benzaldimine 138 to afford corresponding bridged compounds 139a−139c with expected enantioselectivity. 35 The solvent optimization study reported that nonpolar aprotic solvents toluene and m-xylene led to higher yields than their polar counterparts like halogenated solvents. The phosphoric acid 141-catalyzed direct aza Diels− Alder reaction was extended to a series of benzaldimines (138), with an electron donating or electron withdrawing substituent afforded endoisomer 139 in 70−82% yield and with up to 87% enantioselectivities.…”

H 8 −BINOL, a partially reduced form of BINOL, is widely employed in a broad array of organocatalyzed asymmetric methodologies. Over the last 25 years, asymmetric organocatalysis has witnessed an incredible improvement, and an advancement still continues to get a single enantio-enriched product. The broad-spectrum applications of H 8 −BINOL organocatalyst in C−C bond formation, C-heteroatom bond construction, name reactions, pericyclic reactions, and one pot and multicomponent reaction are attracting the attention of researchers. A diversified unique H 8 −BINOL-based catalyst has been synthesized and screened for catalytic activity. In this Review we frame out the H 8 −BINOL catalyzed novel discoveries from the last two decades.

“…When tested, the prelithiated MXene demonstrated a higher specific capacity and reduced Li + ions during SEI formation. Figure 8(a) shows the schematic of the working conditions of the MXenes before and after prelithiation, demonstrating that prelithiation can increase the MXene interlayers and recompense the Li loss in the initial cycle leading to a high reversible capacity [97]. Another study by Naguib et al revealed that upon mixing of V 2 CT x with-TBAOH for two hours, a peak shift from 2θ of 8.9°to 4.6°(c-LP from 19.9 Å to 38.6 Å) was observed.…”

Batteries and supercapacitors have emerged as promising candidates for next-generation energy storage technologies. The rapid development of new two-dimensional (2D) electrode materials indicates a new era in energy storage devices. MXenes are a new type of layered 2D transition metal carbides, nitrides, or carbonitrides that have drawn much attention because of their excellent electrical conductivity, electrochemical and hydrophilicity properties, large surface area, and attractive topological structure. This review focuses on various synthesis methods to prepare vanadium carbide MXenes with and without etchants like hydrofluoric acid, lithium fluoride, and hydrochloric acid to remove the ‘A’ layers of the MAX phase. The goal is to demonstrate the utilization of a less toxic etching method to achieve MXenes of comparable properties to those prepared by traditional methods. The influence of intercalation on the effect of high interlayer spacing between the MXene layers and the performance of MXenes as supercapacitor and battery electrodes is also addressed in this review. Finally, the gaps in the current knowledge for vanadium carbide MXenes in synthesis, scalability, and utilization in more energy storage devices were discussed. he MAX phase.

“…The high resolution V 2p spectrum can be deconvoluted into four components corresponding to V 5+ , V 4+ , V 3+ and V 2+ /V-C, respectively. The peaks of V 3+ are attributed to the loss of V during HF etching [43]. The C 1s spectrum can be deconvoluted into six components corresponding to C-V, C-C, C-O, C=O, O-C-O and -COOH, respectively.…”

V2CTx shows a low ion diffusion barrier, while the multiple oxidation states of vanadium allow V2CTx to participate in multi-electron redox reactions, which demonstrates a greater potential for electrochemical energy storage applications. However, the lateral arrangement of V2CTx lamellae tends to cause the accumulation and collapse of the structure. Herein, the two-dimensional layered V2CTx is modified with Ag+ and Cu2+, the V2CTx/Ag/Cu composite is successfully prepared. The Ag NPs and Cu NPs grown between the layers of V2CTx can effectively suppress the accumulation of the lamellae and ensure the smooth transfer of electrolyte ions and electrons between the layers. Meanwhile, the doping of Ag NPs and Cu NPs can enlarge the interlayer spacing of V2CTx, which can expose more active contact sites for electrolyte ions, shorten the diffusion path of electrolyte ions, and effectively improve the electrochemical performance of V2CTx. The Ag NPs and Cu NPs agglomerate in the delamination of V2CTx to form a conductive channel covering multiple layers, which facilitates cross-layer electron transfer and reduces the internal resistance of the V2CTx/Ag/Cu composite. Basis on the above reasonable structural designs, the internal resistance of the V2CTx/Ag/Cu composite is only 0.72 Ω, showing excellent diffusion ability of K+. The result represents a new step forward in exploring the electrochemical properties of two dimensional materials of V2CTx.
