“…However, the scope of papers were on either the complexation or the electrochemical reduction of metals ( Murase et al, 2004 ; Hamada et al, 2008 ; Ohgai et al, 2013 ; Aaboubi et al, 2015 ; Péter et al, 2021 ). Moreover, individual papers investigated a few synthesis parameters in a narrow range, and there is no baseline condition among them ( Beltowska-Lehman et al, 2012 ; Ohgai et al, 2013 ; Aaboubi et al, 2015 ; Bigos et al, 2017 ; Stryuchkova et al, 2017 ). Although two mechanisms were proposed for the induced co-deposition, the reports only mentioned either one ( Ernst and Holt, 1958 ; Fukushima et al, 1979 ; Creager et al, 1982 ; Chassaing et al, 1989 ; Crousier et al, 1992 ; Rengakuji et al, 1994 ; Podlaha and Landolt, 1997 ).…”
