“…The development of new materials with high performance and reuse ability has motivated the researches to produce value added catalysts to be used in several catalytic processes [1][2][3]. Carbonaceous materials are interesting solids to be used in heterogeneous catalysis because of their extraordinary textural characteristics such as tunable and uniform pore sizes and high surface area [4].…”

“…By expanding the aqueous interface, accelerations of the reaction velocity up to 3 orders of magnitude has been measured (Enami et al, 2014). This may be one of the reasons why ironcontaining solid surfaces made of fractal iron oxides, pyrite, activated carbon, graphite, carbon nanotubes, vermiculite, pillared clays and zeolites have been tested as efficient Fenton reagents (Pignatello et al, 2006;Pinto et al, 2012;Teixeira et al, 2012).…”

Climate engineering by mimicking natural dust climate control: the iron salt aerosol method

Abstract. Power stations, ships and air traffic are among the most potent greenhouse gas emitters and are primarily responsible for global warming. Iron salt aerosols (ISAs), composed partly of iron and chloride, exert a cooling effect on climate in several ways. This article aims firstly to examine all direct and indirect natural climate cooling mechanisms driven by ISA tropospheric aerosol particles, showing their cooperation and interaction within the different environmental compartments. Secondly, it looks at a proposal to enhance the cooling effects of ISA in order to reach the optimistic target of the Paris climate agreement to limit the global temperature increase between 1.5 and 2 • C.Mineral dust played an important role during the glacial periods; by using mineral dust as a natural analogue tool and by mimicking the same method used in nature, the proposed ISA method might be able to reduce and stop climate warming. The first estimations made in this article show that by doubling the current natural iron emissions by ISA into the troposphere, i.e., by about 0.3 Tg Fe yr −1 , artificial ISA would enable the prevention or even reversal of global warming. The ISA method proposed integrates technical and economically feasible tools.

The heterogeneous Fenton reaction can generate highly reactive hydroxyl radicals (UOH) from reactions between recyclable solid catalysts and H 2 O 2 at acidic or even circumneutral pH. Hence, it can effectively oxidize refractory organics in water or soils and has become a promising environmentally friendly treatment technology. Due to the complex reaction system, the mechanism behind heterogeneous Fenton reactions remains unresolved but fascinating, and is crucial for understanding Fenton chemistry and the development and
