This book covers the recent development of metal oxides, hydroxides
and their carbon composites for electrochemical oxidation of water
in the production of hydrogen and oxygen as fuels. It includes a
detailed discussion on synthesis methodologies for the metal
oxides/hydroxides, structural/morphological characterizations, and
the key parameters (Tafel plot, Turnover frequency, Faradic
efficiency, overpotential, long cycle life etc.) needed to evaluate
the electrocatalytic activity of the materials. Additionally, the
mechanism behind the electro oxidation process is presented.
Readers will find a comprehensive source on the close correlation
between metal oxides, hydroxides, composites, and their properties
and importance in the generation of hydrogen and oxygen from water.
The depletion of fossil fuels from the earth's crust, and related
environmental issues such as climate change, demand that we search
for alternative energy resources to achieve some form of
sustainable future. In this regard, much scientific research has
been devoted to technologies such as solar cells, wind turbines,
fuel cells etc. Among them fuel cells attract much attention
because of their versatility and efficiency. In fuel cells,
different fuels such as hydrogen, CO2, alcohols, acids, methane,
oxygen/air, etc. are used as the fuel, and catalysts are employed
to produce a chemical reaction for generating electricity. Hence,
it is very important to produce these fuels in an efficient,
eco-friendly, and cost effective manner. The electrochemical
splitting of water is an environmentally friendly process to
produce hydrogen (the greener fuel used in fuel cells), but the
efficiencies of these hydrogen evolution reactions (cathodic half
reaction) are strongly dependent on the anodic half reaction
(oxygen evolution reaction), i.e., the better the anodic half, the
better will be the cathodic reaction. Further, this oxygen
evolution reaction depends on the types of active electrocatalysts
used. Though many more synthetic approaches have been explored and
different electrocatalysts developed, oxide and hydroxide-based
nanomaterials and composites (with graphene, carbon nanotubes etc.)
show better performance. This may be due to the availability of
more catalytic surface area and electro active centers to carry out
the catalysis process.
