abstract = {Nowadays, there is an increasing interest in the development of promising, e cient,
and environmentally friendly wastewater treatment technologies. Among them are the advanced
oxidation processes (AOPs), in particular, catalytic wet peroxidation (CWPO), assisted or not by
radiation. One of the challenges for the industrial application of this process is the development of
stable and e cient catalysts, without leaching of the metal to the aqueous phase during the treatment.
Gold catalysts, in particular, have attracted much attention from researchers because they show
these characteristics. Recently, numerous studies have been reported in the literature regarding the
preparation of gold catalysts supported on various supports and testing their catalytic performance
in the treatment of real wastewaters or model pollutants by CWPO. This review summarizes this
research; the properties of such catalysts and their expected e ects on the overall e ciency of
the CWPO process, together with a description of the e ect of operational variables (such as pH,
temperature, oxidant concentration, catalyst, and gold content). In addition, an overview is given of
the main technical issues of this process aiming at its industrial application, namely the possibility of
using the catalyst in continuous flow reactors. Such considerations will provide useful information
for a faster and more e ective analysis and optimization of the CWPO process.},
