In this work, a new hydrothermal route with low-toxicity etching agents (NaBF4, HCl) was used to synthesize Ti3C2 MXene (h-Ti3C2). Compared with the Ti3C2 prepared by the traditional HF etching method (t-Ti3C2), the h-Ti3C2 has the higher c lattice parameter, larger interlayer ...
We find the calculated relaxed lattice parameters of freestanding B2C to be a=2.578 Å and b=3.425 Å, and the bond lengths of B-B and B-C are 1.556 Å and 1.683 Å, respectively, which are in good agreement with the previous studies23, 24, 27. The corresponding electronic band...
technology to maintain the stability of wind power and the return on investment of enterprises [26]. They calculated the fluctuating cost of wind energy to obtain the maximum capacity of each generating unit. Schmidt et al. developed an energy management control strategy that considers the impact ...
MXene, layered double hydroxide (LDH) or metal–organic frameworks (MOF), due to their low cost and abundance, are widely studied to improve OER efficiency [5,6,7]. Moreover, doping of transition metals into various structures alters their...

The compatible and controllable growth processes, along with the grown stable 2D η-Mo3C2 superconductors, will accelerate MXene-based van der Waals heterostructures or junctions in superconducting electronics or other potential applications [35]. CONCLUSIONS In summary, we develop a two-step vapor...
Hydrogen spillover phenomenon of metal-supported electrocatalysts can significantly impact their activity in hydrogen evolution reaction (HER). However, design of active electrocatalysts faces grand challenges due to the insufficient understandings on ho
(#191) containing alternating layers of Mg and B atoms stacked along the\(\overrightarrow{c}\)lattice direction, as shown in Fig.1(a)42. The bonding between the Mg and B atoms is purely ionic, which means that Mg atoms donate two electrons to B atoms, thereby making each Mg 2+and...
Ti3C2Tx MXene as a growth template for amorphous RuOx in carbon nanofiber-based flexible electrodes for enhanced pseudocapacitive energy storage Article Open access 12 May 2023 Introduction The development of energy storage devices is indisputably one of the great challenges in the 21st century to ...
