DESCRIPTION:Prof. Raffaella Buonsanti\, EPFL\nElectrochemical energy devic
 es require materials which conduct charges\, catalyze reactions at the int
 erfaces and are stable under operating conditions. Multicomponent nanomate
 rials\, wherein the different parts synergistically function together\, ar
 e ideal candidates to satisfy such a demand for complexity\, thus enabling
  technological progress in many applications. Our laboratory uses colloida
 l chemistry to tailor-make highly tunable hybrid nanomaterials using nanoc
 rystals as principal building blocks.\nAfter a general introduction on col
 loidal nanocrystals\, I will focus on a couple of examples which illustrat
 e the benefit of using them as platforms to advance studies in artificial 
 photosynthesis. Specifically\, I will discuss our work on complex metal ox
 ides and quantum dots nanocomposites as light absorbers for water splittin
 g and on metal nanocrystals as electrocatalysts for CO2 reduction.1-4\n \

 track Assistant Professor in the Institute of Chemical Sciences and Engine
 ering and head of the Laboratory of Nanochemistry for Energy at EPFL since
  November 2015.\nShe received her Master Degree in Chemistry from the Univ
 ersity of Bari in 2006. In 2010\, she graduated in Chemistry from the Univ
 ersity of Salento working at the National Nanotechnology Laboratory (NNL\,
  in Lecce-Italy). She was at Lawrence Berkeley National Laboratory for alm
 ost six years\, first as a postdoctoral researcher (2010-2012) and project
  scientist (2012-2013) at the Molecular Foundry and after as a tenure-trac
 k staff scientist (2013-2015) in the Materials Science Department within t
 he Joint Center of Artificial Photosynthesis (JCAP).\nHere at EPFL\, Raffa
 ella implements a highly interdisciplinary approach\, spanning from Chemis
 try to Materials Science and Chemical Engineering\, to address fundamental
  challenges of energy technologies. Through her core expertise in colloida
 l synthesis\, she develops novel approaches to complex materials to drive 
 chemical transformations\, with particular emphasis to energy-related reac
 tions such as CO2 reduction and water oxidation.\n \n \n
