  This work presents the emergence of superconductivity in Re substituted
topological Weyl semimetal MoTe$_{2}$. Re substitution for Mo sites lead to a
sizable enhancement in the superconducting transition temperature (T$_{c}$). A
record high T$_{c}$ at ambient pressure in a 1T$'$-MoTe$_{2}$ (room temperature
structure) related sample is observed for the Mo$_{0.7}$Re$_{0.3}$Te$_{2}$
composition (T$_{c}$ = 4.1 K, in comparison MoTe$_{2}$, shows a T$_{c}$ of 0.1
K). The experimental and theoretical studies indicate that Re substitution is
doping electrons and facilitates the emergence of superconductivity by
enhancing the electron-phonon coupling and density of states at the Fermi
level. Our findings, therefore, open a new way to further manipulate and
enhance the superconducting state together with the topological states in 2D
van der Waals materials.
