Exploring the Potential of MBenes Supercapacitors: Fluorine-Free Synthesized MoAl_1-xB with Ultrahigh Conductivity and Open Space.

ABSTRACT: The present study describes the synthesis of multilayered MBenes MoAl_1-xB with different degrees of Al deintercalation using a mild, fluorine-free approach of dilute alkali to remove Al from MoAlB. We propose an etching route and compare it to conventional fluoride etching products. Additionally, the study explores the possible application and energy storage mechanism of MBenes in supercapacitors, marking the first investigation of its kind. At room temperature, 1/24-MoAl_1-xB with terminal groups -OH exhibits ∼25% Al removal in 1 wt % NaOH for 24 h, outperforming traditional etching technology. Increasing the Al removal exposed more open space, resulting in a higher capacitance. Compared to LiF/HCl-MoAl_1-xB (etched by LiF + HCl), 1/24-M
