I'm trying to include a citation in a beamer frame following the instruction here. However, I couldn't figure out how to place them inside a subfigure environment. Namely, my code:

\begin{frame}
  \frametitle{Reactive-transport systems}
  \begin{figure}
    \centering
    \begin{subfigure}{0.45\textwidth}
      \includegraphics[width=0.45\textwidth]{Chabanon2017.jpg}
      \caption{Here is text \footfullcite{Chabanon2017}}
    \end{subfigure}
    \begin{subfigure}{0.45\textwidth}
      \includegraphics[width=0.45\textwidth]{Steefel2005.jpg}
      \caption{Here is text \footfullcite{Steefel2005}}
    \end{subfigure}
  \end{figure}
\end{frame}

And this is what I'm seeing: enter image description here

Any suggestions on how to go around it?

EDIT: Add minimal working example:

\documentclass{beamer}

\usepackage{pgf}
\usepackage{xcolor}
\usepackage[utf8]{inputenc}
% Citation                                                                                                                      
\usepackage[backend=bibtex, style=science]{biblatex}

\usepackage{subcaption}
\usepackage{filecontents}

\begin{filecontents}{vorlage.bib}

 @article{test1,
    author  = {Shen Lin and Brian W. Kernighan},
    title   = {An Effective Heuristic Algorithm for the Travelling-Salesman Problem},
    journal = {Operations Research},
    volume  = {21},
    year    = {1973},
    pages   = {498--516},
 }

@BOOK{test,
  title = {The Infamous Test},
  publisher = {Testington Test},
  year = {2007},
  author = {John Doe},
  address = {Testville},
}

@ARTICLE{test2,
  author = {Testi, T.},
  year = {2003},
  title = {Testartikel},
  journal = {Testjournal}
}
\end{filecontents}



% Hacky fix to citation                                                                                                         
\makeatletter
\def\blx@maxline{77}
\makeatother

% Add bibliography file                                                                                                         
\bibliography{vorlage.bib}

\begin{document}

\begin{frame}
\frametitle{Introduction and motivation - the title}
\section[Motivation]{Introduction and motivation}
\begin{figure}
\centering
\begin{subfigure}{.45\textwidth}
  \centering
  \includegraphics[width=\linewidth]{example-image}
  \caption{A subfigure \footfullcite{test}}
  \label{fig:sub1}
\end{subfigure}%
\begin{subfigure}{.45\textwidth}
  \centering
  \includegraphics[width=\linewidth]{example-image}
  \caption{A subfigure \footfullcite{test1}}
  \label{fig:sub2}
\end{subfigure}
\caption{A figure with two subfigures \footfullcite{test2}}
\label{fig:test}
\end{figure}
\end{frame}

\end{document}

This will produce the following result:

enter image description here

and you can see that the citation is stuck underneath each subfigure instead of gathering all at the bottom of the page.

Based on Footfullcitetext and beamer: incremental numbering you could work around the problem like this:

\documentclass{beamer}

%\usepackage{pgf}
%\usepackage{xcolor}
\usepackage[utf8]{inputenc}
% Citation                                                                                                                      
\usepackage[style=science]{biblatex}

\usepackage{subcaption}
\usepackage{filecontents}

\begin{filecontents}{vorlage.bib}

 @article{test1,
    author  = {Shen Lin and Brian W. Kernighan},
    title   = {An Effective Heuristic Algorithm for the Travelling-Salesman Problem},
    journal = {Operations Research},
    volume  = {21},
    year    = {1973},
    pages   = {498--516},
 }

@BOOK{test,
  title = {The Infamous Test},
  publisher = {Testington Test},
  year = {2007},
  author = {John Doe},
  address = {Testville},
}

@ARTICLE{test2,
  author = {Testi, T.},
  year = {2003},
  title = {Testartikel},
  journal = {Testjournal}
}
\end{filecontents}

An alternative to @samcarter's since I done it before see the answer:

\documentclass{beamer}

\usepackage{pgf}
\usepackage{xcolor}
\usepackage[utf8]{inputenc}
% Citation                                                                                                                      
\usepackage[backend=bibtex, style=science]{biblatex}

\usepackage{subcaption}
\usepackage{filecontents}
\newsavebox{\mybox}

\begin{filecontents}{vorlage.bib}

 @article{test1,
    author  = {Shen Lin and Brian W. Kernighan},
    title   = {An Effective Heuristic Algorithm for the Travelling-Salesman Problem},
    journal = {Operations Research},
    volume  = {21},
    year    = {1973},
    pages   = {498--516},
 }

@BOOK{test,
  title = {The Infamous Test},
  publisher = {Testington Test},
  year = {2007},
  author = {John Doe},
  address = {Testville},
}

@ARTICLE{test2,
  author = {Testi, T.},
  year = {2003},
  title = {Testartikel},
  journal = {Testjournal}
}
\end{filecontents}

\makeatletter
\def\blx@maxline{77}
\makeatother

% Add bibliography file                                                                                                         
\bibliography{vorlage.bib}

\begin{document}

\begin{frame}
\frametitle{Introduction and motivation - the title}
\section[Motivation]{Introduction and motivation}
\begin{figure}
\centering
\begin{subfigure}{.45\textwidth}
  \centering
  \includegraphics[width=\linewidth]{example-image}
  \caption{A subfigure\footnotemark[1]}% \footfullcite{test}}
  \label{fig:sub1}
\end{subfigure}%
\begin{subfigure}{.45\textwidth}
  \centering
  \includegraphics[width=\linewidth]{example-image}
  \caption{A subfigure \footnotemark[2]}
  \label{fig:sub2}
\end{subfigure}
\caption{A figure with two subfigures\footnotemark[3]}% \footfullcite{test2}}
\label{fig:test}
\end{figure}
\sbox1{\hbox{\footfullcite[1]{test}
\footfullcite[2]{test1}
\footfullcite[3]{test2}}}
\end{frame}

\end{document}

PS: The output is the same but I just used the \footnotemark[] trick and let the \footfullcite commands to be expanded inside an \sbox (but actually outside of it). The good part is that no need of advanced bib(La)TeX knowledge is needed...

    Nice trick with the \sbox! – user36296 Mar 14 at 17:47
