<string language="fre"><![CDATA[Solar energy is
well-recognized as a sustainable and clean energy source. Among the various
approaches to solar energy conversion, solar-driven hydrogen production is one
of the most promising ways to convert solar energy into hydrogen, a storable
fuel. Hydrogen is undoubtedly one of the most attractive renewable alternatives
to fossil fuels for a number of reasons: (i) hydrogen can be safely stored;
(ii) it is an excellent energy carrier since it can store 3 times as much
energy as conventional natural gas; (iii) its combustion is environmentally
friendly (no release of greenhouse gases or hazardous by-products). However,
the production of hydrogen currently relies in steam reforming of CH4 and CO,
and thus, involves the consumption of fossil fuel energy and the emission of
greenhouse gases. There are efforts to find alternative renewable technologies
to produce hydrogen, the so-called green hydrogen.
 
It is well-known
that the efficiency of heterogeneous photocatalysis for hydrogen generation
from water splitting is quite low. The efficiency of photocatalysis hydrogen
generation can be improved by using aqueous sacrificial agents (organic
electron donors) dissolved in water. Industrial wastewater containing high
concentrations of methanol/glycerol/formic acid have been used as feedstock.
Effluents from municipal wastewaters could also be used, as they would contain
dozens of mg/L of organic load. This means that in a simultaneous process,
hydrogen generation and contaminants removal can take place. It is important to
notice that the application of this technology has a double purpose: first, to
produce a clean fuel such as hydrogen and, second, to treat, reduce the organic
load and decontaminate wastewater in certain extent.]]></string></description>
