Abstract

At the end of the last century, the use of gold as a catalyst was uncommon. Masatake Haruta, however, showed that gold divided into extremely small particles is an outstanding catalyst. This educational article explains that the immobilization of both nanoparticles and isolated gold atoms on an insoluble support strongly increases the catalytic activity of this kind of systems in a considerable number of chemical reactions of industrial interest.

Keywords: Gold nanoparticles, single metal atoms, catalysis.

Author Biographies

Oriol Rossell, Universitat de Barcelona

doctor en química (1974) per la Universitat de Barcelona i catedràtic (1991) de la mateixa universitat, actualment jubilat, fou el primer editor de la revista de la societat catalana de química (2000). Ha treballat en diferents camps de recerca, com ara la química organometàl·lica, els clústers metàl·lics, els dendrímers i, més recentment, la catàlisi. Ha publicat més d’un centenar d’articles en revistes internacionals i ha dirigit un bon nombre de tesis doctorals.

Inmaculada Angurell, Universitat de Barcelona

doctora en química (2006) per la Universitat de Barcelona (UB). Després d’una etapa postdoctoral a l’Imperial College London, el 2008 es va reincorporar al Departament de Química Inorgànica i Orgànica de la UB, on actualment és professora agregada. La seva recerca se centra en la síntesi de nanopartícules metàl·liques funcionalitzades per a aplicacions catalítiques i amb propietats luminescents.
