LA TRANSICION DE UN SISTEMA ENERGETICO BASADO EN COMBUSTIBLES FOSILES, CON EL CONSECUENTE IMPACTO EN EL MEDIO AMBIENTE, HACIA ES UN SISTEMA ENERGETICO SOSTENIBLE Y SEGURO ES UNO DE LOS RETOS DE LA HUMANIDAD, Y ASI SE RECOGE EN EL RETO 3 DE LA ESTRATEGIA ESPAÑOLA DE CIENCIA Y TECNOLOGIA Y DE INNOVACION 2013-2020. EN ESTE CONTEXTO, LA UTILIZACION DE SEMICONDUCTORES ACTIVOS BAJO IRRADIACION VISIBLE SE POSTULA COMO UNA TECNOLOGIA CLAVE PARA EL APROVECHAMIENTEO DE LA LUZ SOLAR. LAS VENTAJAS QUE PRESENTA EL USO DE FOTOCATALIZADORES FRENTE A LOS COMBUSTIBLES FOSILES SON ENORMES. SON CAPACES DE ACTIVARSE SIMPLEMENTE EN PRESENCIA DE LA LUZ SOLAR Y NO REQUIEREN EL USO DE METALES PESADOS PELIGROSOS, POR EJMPLO, PARA SU PREPARACION Y/O UTILIZACION. SIN EMBARGO, LAS APLICACIONES PRACTICAS DE ESTA TECNICA SE LIMITAN EN GRAN MEDIDA DEBIDO A DOS FACTORES: EL ESTRECHO RANGO DE RESPUESTA DE LUZ Y LA RECOMBINACION DE LOS PARES ELECTRON-HUECO FOTOINDUCIDOS EN EL FOTOCATALIZADOR. PESE AL ENORME ESFUERZO REALIZADO HASTA LA ACTUALIDAD, LAS EFICIENCIAS ACTUALES NO PERMITEN UNA TRANSICION REAL A UN SISTEMA ENERGETICO SOSTENILBLE. LA IP DE ESTE PROYECTO DIRIGE, DESDE SEPTIEMBRE DE 2012, LA LINEA DE INVESTIGACION ¿NANOTITANIAS PARA APLICACIONES MEDIOAMBIENTALES, EN FOTOCATALISIS Y CELDAS SOLARES¿ EN EL LABORATORIO DE NANOTECNOLOGIA MOLECULAR DE LA UA, ORIENTADA A LA MODULACION DEL BAND GAP EN MATERIALES HIBRIDOS BASADOS EN TITANIA MEDIANTE LA INCORPORACION DE DISTINTA FUNCIONALIDAD QUIMICA EN EL INTERIOR DE LA ESTRUCTURA DE LA MISMA. LA HIPOTESIS SE BASA EN LA DEPENDENCIA DEL BAND GAP CON LA ESTRUCTURA DEL SEMISCONDUCOR. SIGUIENDO ESTA METODOLOGIA SE HA OBTENIDO UNA SERIE DE MATERIALES, FOTOCATALIZADORES HIBRIDOS ESTABLES Y ACTIVOS EN LA REGION DEL VISIBLE EMPLEANDO PARA ELLO UNA METODOLOGIA VERSATIL Y ECONOMICA. TITANLIGHT PRETENDE DAR UN PASO MAS EN EL AREA DE TITANIAS ACTIVAS EN EL VISIBLE PARA APLICACIONES MEDIOAMBIENTALES/ENERGETICAS MEDIANTE EL DESARROLLO DE LAS DOS LINEAS DE INVESTIGACION BASADAS EN TITANIAS PREPARADAS POR UNA METODOLOGIA SIMILAR A LA PREVIAMENTE ESTABLECIDA POR LA IP. LA PRIMERA LINEA ES BASA EN LA PREPARACION DE UNA SERIE DE TITANIAS ACTIVAS EN EL VISIBLE PARA APLICACIONES MEDIOAMBIENTALES MEDIANTE EL EMPLEO DE ORGANOALCOXIDOS DE TITANIO, SINTETIZADOS ESPECIFICAMENTE PARA ESTE PROYECTO. EL OBJETIVO FINAL ES LA EVALUACION DE DICHOS FOTOCATALIZADORES EN PROCESOS DE DESCONTAMINACION MEDIOAMBIENTAL TALES COMO ENSAYOS DE AUTO-LIMPIEZA, DEGRADACION DE CONTAMINANTES ACUOSOS Y PURIFICACION DE AIRE. CABE DESTACAR QUE ACCIONA HA MOSTRADO SU INTERES Y DISPONIBILIDAD PARA ENSAYAR EN CONDICIONES REALES LOS MATERIALES QUE PRESENTEN PROPIEDADES OPTIMAS DE CARA A LA ELIMINACION DE NOX EN DOS APLICACIONES CLAVE. LA SEGUNDA LINEA SE BASA EN EMPLEAR DICHA METODOLOGIA PARA LA INCORPORACION DE UNA SERIE DE DYES EN EL INTERIOR DE LA ESTRUCTURA DE LA TITANIA, PROTEGIENDOLOS DE ALGUNA MANERA, DE CARA AL DISEÑO DE UNA NUEVA FAMILIA DE CELDAS SOLARES DE TIPO DSSCS FLEXIBLES A BAJA TEMPERATURA. LOS ELECTRODOS PREPARADOS MEDIANTE SINTERIZACION A BAJA TEMPERATURA SE EMPLEARAN COMO DISPOSITIVOS EN LA CONSTRUCCION DE CELDAS SOLARES Y SE EVALUARAN EN EL GRUPO DEL PROF. GULDI (ALEMANIA) A TAL FIN. (Spanish)

THE TRANSITION OF AN ENERGETIC SYSTEM BASED ON FOSSIL FUELS, WITH THE CONSEQUENT IMPACT ON THE ENVIRONMENT, TOWARDS A SUSTAINABLE AND SAFE ENERGY SYSTEM IS ONE OF THE CHALLENGES OF HUMANITY, AND THIS IS REFLECTED IN CHALLENGE 3 OF THE SPANISH STRATEGY OF SCIENCE AND TECHNOLOGY AND INNOVATION 2013-2020. IN THIS CONTEXT, THE USE OF ACTIVE SEMICONDUCTORS UNDER VISIBLE IRRADIATION IS POSTULATED AS A KEY TECHNOLOGY FOR THE APROVECHAMIENTO OF SUNLIGHT. THE ADVANTAGES OF USING PHOTOCATALYSTS OVER FOSSIL FUELS ARE ENORMOUS. THEY ARE ABLE TO ACTIVATE SIMPLY IN THE PRESENCE OF SUNLIGHT AND DO NOT REQUIRE THE USE OF DANGEROUS HEAVY METALS, E.G. FOR THEIR PREPARATION AND/OR USE. HOWEVER, PRACTICAL APPLICATIONS OF THIS TECHNIQUE ARE LARGELY LIMITED DUE TO TWO FACTORS: THE NARROW RANGE OF LIGHT RESPONSE AND THE RECOMMENDATION OF THE ELECTRON-HOLE PAIRS PHOTOINDUCED IN THE PHOTOCATALYST. DESPITE THE ENORMOUS EFFORT MADE TO DATE, CURRENT EFFICIENCIES DO NOT ALLOW A REAL TRANSITION TO A SUSTAINILBLE ENERGETIC SYSTEM. THE IP OF THIS PROJECT HAS LED, SINCE SEPTEMBER 2012, THE RESEARCH LINE NANOTIITANIAS FOR ENVIRONMENTAL APPLICATIONS, IN PHOTOCATALYSIS AND SOLAR CELLS, IN THE MOLECULAR NANOTECHNOLOGY LABORATORY OF THE AU, AIMED AT MODULATING THE BAND GAP IN HYBRID MATERIALS BASED ON TITANIA BY INCORPORATING DIFFERENT CHEMICAL FUNCTIONALITY WITHIN THE STRUCTURE OF THE PROJECT. THE HYPOTHESIS IS BASED ON THE DEPENDENCE OF THE BAND GAP WITH THE STRUCTURE OF THE SEMISCONDUCOR. FOLLOWING THIS METHODOLOGY WE HAVE OBTAINED A SERIES OF MATERIALS, STABLE AND ACTIVE HYBRID PHOTOCATALYSTS IN THE VISIBLE REGION USING A VERSATILE AND ECONOMICAL METHOD. TITANLIGHT INTENDS TO TAKE ONE STEP FURTHER IN THE AREA OF ACTIVE TITANIAS IN THE VISIBLE ONE FOR ENVIRONMENTAL/ENERGETIC APPLICATIONS BY DEVELOPING THE TWO LINES OF RESEARCH BASED ON TITANIAS PREPARED BY A METHODOLOGY SIMILAR TO THAT PREVIOUSLY ESTABLISHED BY THE IP. THE FIRST LINE IS BASED ON THE PREPARATION OF A SERIES OF ACTIVE TITANIAS IN THE VISIBLE ONE FOR ENVIRONMENTAL APPLICATIONS THROUGH THE USE OF TITANIUM ORGANOALCOXIDOS, SYNTHESISED SPECIFICALLY FOR THIS PROJECT. THE FINAL OBJECTIVE IS THE EVALUATION OF THESE PHOTOCATALYSTS IN ENVIRONMENTAL DECONTAMINATION PROCESSES SUCH AS SELF-CLEANING TESTS, DEGRADATION OF AQUEOUS POLLUTANTS AND AIR PURIFICATION. IT SHOULD BE NOTED THAT ACTUA HAS SHOWN ITS INTEREST AND AVAILABILITY TO TEST IN REAL CONDITIONS MATERIALS THAT HAVE OPTIMAL PROPERTIES FOR THE ELIMINATION OF NOX IN TWO KEY APPLICATIONS. THE SECOND LINE IS BASED ON USING THIS METHOD FOR THE INCORPORATION OF A SERIES OF DYES INSIDE THE TITANIA STRUCTURE, PROTECTING THEM IN SOME WAY, IN VIEW OF THE DESIGN OF A NEW FAMILY OF SOLAR CELLS OF TYPE DSSCS FLEXIBLE AT LOW TEMPERATURE. ELECTRODES PREPARED BY SINTERING AT LOW TEMPERATURE SHALL BE USED AS DEVICES IN THE CONSTRUCTION OF SOLAR CELLS AND EVALUATED IN THE GROUP OF PROF. GULDI (GERMANY) FOR THIS PURPOSE. (English)
