摘要
Discovered in 2011,MXene becomes a most recent and active member of two-dimensional materials.Since then,the landscape of MXene grows significantly and now more than 30 different MXenes were obtained experimentally.Though most of the efforts are contributed to Ti-MXenes which have the highest level of maturity of the synthetic technology and productivity,in recent years,new-MXene systems with Molybdenum(Mo),Vanadium(V),and Niobium(Nb)as the transition metals demonstrated their unique properties and applications.The development of new-MXenes not only expands the synthetic methods and applications of MXenes but also faces new challenges.Therefore,a timely summary of Mo-,V-and Nb-MXenes will be extremely beneficial.Here,the synthetic methods of the selected new-MXenes are summarized and their most recent applications are highlighted to provide an outlook for the future development of MXenes.
