dc.description.abstract | The combination of a platinum group material (i.e. ruthenium)
with a first row transition metal (i.e. manganese) could provide
stability and lower the cost of OER electrocatalyst, while still
obtaining good OER properties. In this work classical
electrochemical techniques have been used to study the
electrocatalytic properties of thermally prepared manganese, mixed
manganese/ruthenium and ruthenium based electrocatalysts on a
titanium substrate at three different annealing temperatures for
OER. The structure and morphology of the thermally decomposed
oxide materials are examined using Scanning Electron Microscopy
(SEM) and Fourier Transform Infrared (FTIR) spectroscopy.
Turnover Frequency (TOF) numbers are also calculated. The initial
OER overpotential values of eight electrocatalysts, in this study,
are lower than that of the lowest known OER electrocatalyst, RuO
2
.
All SEM images with 10
–
100 % of RuO
x
show a mud-cracked
morphology. This morphology is attributed to the excellent
electrocatalytic activity of RuO
