I would start with turbo_eels.x code of TDDFT module that is distributed
with QE. Of course you have to cautious while dealing with a 2D system
(i.e. check convergence w.r.t to vacuum and etc) but in principle you
can obtain momentum-dependent dielectric function.

I doubt if you can obtain this from QE or not. The plot is essentially
the -Im\epsilon_Q{\omega}^{-1}. You can have a look at the Yambo
tutail for computing this object from QE DFT calculations.

YAMBO code - The Yambo project <http://www.yambo-code.org/index.php>
Yambo is a FORTRAN/C code for Many-Body calculations in solid state
and molecular physics. Yambo relies on the Kohn-Sham wavefunctions
generated by two DFT public codes: abinit, and PWscf.The code was
originally developed in the Condensed Matter Theoretical Group of the
Physics Department at the University of Rome "Tor Vergata" by Andrea
Marini. ...

I'm studying the plasmonic properties of graphene decorated with some
metals. I'm using epsilon.x in my study, but I saw the attached graphs
published in reference "Despoja, Vito, et al. /Physical Review B/87.7
(2013): 075447." and we would like to reproduce such outcomes for our
research. Please tell me the steps needed to be followed to reproduce
such graphs.
