MWCNT-modified MXene as cost-effective efficient bifunctional catalyst for overall water splitting Syedah Afsheen Zahraa and Syed Rizwan *a Abstract Utilization of cost-effective, bifunctional, and efficient electrocatalysts for complete water splitting is desirable for sustainable clean hydrogen energy. In last decade, MXenes, a family of emerging two-dimensional (2D) materials with unique physiochemical properties, enticed scientists because of their use in different applications.
