“…This includes transfer of activated oxygen from the support (i.e., reducible or irreducible support), or special active sites at the metal/oxide boundary [8,[54][55][56][57][58][59][60][61][62][63][64]. Finally, there are a number of reports of catalysts consisting of single or a few Au + ions in the support [27,[65][66][67][68][69][70][71][72][73][74][75][76][77][78][79][80][81]. We note that combinations of the above effects can come into play; the gold-support interaction may for instance determine the morphology of the gold particles and thus influence the number of low-coordinated atoms or the strain.…”

The origin of the extraordinary catalytic activity of gold nanoparticles is discussed on the basis of density-functional calculations, adsorption studies on single crystal surfaces, and activity measurements on well characterized supported gold particles. A number of factors are identified contributing to the activity, and it is suggested that it is useful to consider lowcoordinated Au atoms as the active sites, for example, CO oxidation and that the effect of the support can be viewed as structural and electronic promotion. We identify the adsorption energy of oxygen and the Au-support interface energy as important parameters determining the catalytic activity.

“…[5,6] We subsequently extended this concept to show that glycerol could be converted into glyceric acid with a high yield using basic reaction conditions. [7,8] In contrast to palladium and platinum catalysts, gold has been shown to promote the reaction without causing over-oxidation. [8] More recent studies of glycerol oxidation have concentrated on the role of the gold particle size, [9] the catalyst pre-treatment, [10] and the catalyst preparation method.…”

[8] More recent studies of glycerol oxidation have concentrated on the role of the gold particle size, [9] the catalyst pre-treatment, [10] and the catalyst preparation method. [11] While these previous studies have focused on monometallic nanoparticulate gold, we have since demonstrated that alloying gold with palladium can lead to a 25-fold enhancement in the activity of alcohol oxidation.…”

This paper presents a brief review on the current state of glycerochemistry, the chemistry of glycerol. Glycerol is a side product of the glycerides transesterification to produce biodiesel. Besides the fact on a permanent demand of glycerol in modern society, the income rates imposed by the production of biodiesel could not be absorbed, and the need of converting glycerol into valuable products is one of the technological problems that limit the introduction of biodiesel as an alternative to the petroleum diesel. There is a plethora of chemical conversion alternatives for the valorization of glycerol, however the problem itself is a technological one: the development of economically acceptable industrial technology of valorization.Keywords: Glycerol; chemical conversion; valorization; oxidation; polymerization. ResumoO glicerol é um coproduto da transesterificação de glicerídeos a biodiesel. Apesar de haver uma demanda perene de glicerol na sociedade moderna, as quantidades de glicerol impostas pela produção de biodiesel não podem ser absorvidos, e a necessidade de converter o glicerol a produtos de maior valor agregado é um dos gargalos tecnológicos para a introdução de biodiesel ao diesel de petróleo. Há diversas rotas químicas para a valorização do glicerol, mas o problema que se apresenta é de caráter tecnológico: desenvolver tecnologias de valorização viáveis economicamente em níveis industriais.
