Recent progress of MXenes and MXene-based nanomaterials for the electrocatalytic hydrogen evolution reaction

Abstract

Hydrogen as a future energy carrier has several advantages such as sustainability, zero-emission and high energy density. The generation of hydrogen through water electrolysis has been considered the most clean...

MXenes as an emerging class of two-dimensional materials for advanced energy storage devices

“…These similarities open up new possibilities to develop MXene/MXene based composite materials for energy conversion and storage applications. 16–19 These days, smart electricity grids, next-generation devices and electric vehicles (EVs) demand exceptional longstanding properties, high power and high energy to ensure reliable energy supply. Therefore, the development of extensive high-performance energy storage systems is crucial in this regard in order to integrate renewable energy resources into high-power energy applications.…”

An amorphous NiCuFeP@Cu3P nanoarray for an efficient hydrogen evolution reaction

“…[4][5][6] In spite of water electrolysis being full of advantages, this reaction demands a high potential (higher than the theoretical value of 1.23 V), and the sluggish kinetics caused by a large overpotential will increase the power consumption. 7,8 In order to develop efficient electrocatalysts, there is an urgent need to solve the two core issues of reducing the overpotential and increasing the reaction rate of the hydrogen evolution reaction (HER). 9 So far, noble metal catalysts and their compounds (Pt, Ru and RuO 2 ) have shown the optimum hydrogen evolution performance, but their application is restricted by their high cost and low abundance.…”

Recent Advances on MXene‐Based Electrocatalysts toward Oxygen Reduction Reaction: A Focused Review

“…[25] In the present review article, the current researchand-development efforts dedicated to pristine MXenes and their derivatives for realizing ORR catalysts and catalyst support materials for low-temperature FC applications are summarized and discussed. Till date, most of the MXenes research has been done in the field of supercapacitors, [26][27][28] batteries, [29][30][31][32][33] overall water splitting, [34][35][36] and other catalytic applications such as pollutant degradation, CO 2 capture, electromagnetic interference absorption and shielding, and sensors, [37][38][39] there are only very few works devoted to fuel cell cathodic oxygen reduction reaction ORR.…”
