“…The studies of Zhou et al, Wei et al, and Xiong et al have further bolstered the gamut of MBenes with optimizing MAB ternary phase and synthetic protocols (Figure j–l). There are sporadic reports of MBenes applicability toward environmental applications of HER, CO 2 RR, and the nitrogen reduction reaction (NRR) with respect to theoretical foundation and experimental observations. , Recently, there is the growing interest of researchers in escalating the HER, NRR, and CO 2 RR efficiencies of MBenes by tailoring their structural and compositional properties as well depicted in Figure , parts m, n, and o, respectively. Herein, we present an ordered precise commentary on MBenes to address their recent advances, challenges, and prospects for HER, CO 2 RR, and NRR applications.…”
