Periodic Report Summary 1 - MINE (Developing New Strategies for the Production of Viable Hybrid Nanocrystals with Applicability in Energy Conversion and (Photo)catalysis.)

In the recent years, there have been tremendous developments in the synthetic control of inorganic nanocrystals (NCs) which allow tailoring their dimensional regime (morphology, composition and structure) and their physico-chemical properties. These properties, alongside with the ability to cheaply produce NCs in fairly large amounts, lead to their potential applicability in diverse fields, especially in energy harvesting and catalysis. This wide applicability can be increased by designing NCs with a finer morphological control of their properties.

In this context, MINE aboard the most problematic points related to the production of advanced complex materials by integrating the synthesis, the structural characterization and the study of NC’s properties. The research activity reported for this period include three different objectives, i) the design and development of synthetic protocols for the production of multi-component NCs, ii) the study of their Structure-Activity Relationships and iii) the determination of their applicability in model systems and real scenarios. The first objective was to explore new tools and strategies to manipulate the synthesis of inorganic NCs, focusing the study in the nucleation and growth processes that govern the synthesis of NCs. This information allowed us to develop new synthetic routes materials and re-design existing recipes making their synthetic process more robust and allowing for reproducible and scalable synthesis. Getting advantages from this accumulated experience, we focused our study in multi-component materials with solid and hollow morphologies, devoting our efforts on the development of synthetic strategies for the production of metal NCs, metal oxides, semiconductors and oxide of semiconductor. After establishing these synthetic principles, we shifted our efforts to the development of hybrid structures comprising noble metals, combinations of metals and metal oxides and metals and semiconductors. The second objective was the study of the structure-activity relationships of the NCs previously produced, which included the extensive characterization of the NCs (morphology, structure and composition), the determination of their physico-chemical properties, the correlation of their final properties with the synthetic conditions used, and the study of their chemical reactivity. Finally, the third objective was the evaluation of the applicability of obtained NCs as (photo)catalysts both in real systems and model scenarios.

The research progress made and the results obtained represent a significant advance beyond the state of the art in the field, allowing to combine a highly evolved synthetic control with the fundamental understanding of size-and shape-dependent properties at the nanoscale which provides a “tool-box” of materials and morphologies available for researchers in the field to better understand the precise behavior of the solid state at the nanoscale. Besides, on the greater perspective of scientific, technological and social impact the project represents an excellent opportunity for joining, coordinating and advancing pioneering research efforts enabling collaborative internalitional collaborations and technological transfer activities. In parallel, this project has represented a strong support to attain my professional maturity and independence. In this regard, my progress of reintegration to the Spanish scientific system has been extremely positive, receiving in April 2013 a tenure-track "Ramón y Cajal" Fellowship (MICINN, Spanish Government), ranked first in the area of Engineering and Technology, Materials Science.
