摘要：

This paper reports for the first time the synthesis of deintercalated MoAlB particulates which belongs to a family of novel ternary borides called MAB phases by selected etching of Al from these particulates by treating them with a solution of LiF and HCl. The FESEM analysis showed that these particulates had a stacked 2D-particles like morphology reminiscent of multilayered MXenes, but unlike MXenes, the 2D layers were interconnected with anisotropic porosity between them with an average length and width of pores being 257 +/- 126 nm and 35 +/- 10 nm, respectively. The EDS analysis of particulates showed that a typical particulate had a chemistry of (Mo0.67Al0.33)B{O0.19F0.02} which indicate partial deintercalation of Al from the particulates. These novel particulates were also referred to as MABenes due to their microstructural similarity with multilayered MXenes.
