Characterization of membranes in non-steady state
(Universitat Politècnica de Catalunya, 2019-05-28)
Treball Final de Grau
Accés obertIon exchange membranes (IEMs) have been established as a key component in industrial water desalination and electrolysis processes. Thus, nowadays, they are being studied and developed for application ... -
Disseny d'una planta basada en electrolitzadors PEM i fotocatàlisi per a l'obtenció d'hidrogen a partir d'aigua
(Universitat Politècnica de Catalunya, 2022-07-19)
Treball Final de Grau
Accés restringit per decisió de l'autorEn el present treball s’ha dissenyat una planta per produir hidrogen a partir d’aigua mitjançant un reactor híbrid format per tres electrolitzadors PEM en sèrie i un reactor fotocatalític. En el disseny, també s’ha inclòs ... -
Electrocatalytic production of hydrogen boosted by organic pollutants and visible light
(2006-01)
Article
Accés restringit per política de l'editorialA new method to produce high-purity hydrogen using photoelectrocatalytic reactions is studied. This integrated process uses solar energy and the Gibbs free energy of oxidation of organic wastes to help reducing the energy ... -
High-pressure electrolysis
(Springer, 2016)
Capítol de llibre
Accés restringit per política de l'editorialHigh-pressure electrolysis (also called high-pressure electrolysis HPE) is the water electrolysis performed at pressures higher than ambient in which electrical energy is the driving force of the water decomposition to ... -
High-temperature electrolysis
(Springer, 2016)
Capítol de llibre
Accés restringit per política de l'editorialHigh-temperature electrolysis (also called steam electrolysis) is the water electrolysis at temperatures that ranged between 700 and 1,000 °C in which electrical energy is the driving force of water splitting to produce ... -
Sistema de Aprovechamiento de la Energía de las Olas del Mar
(Universitat Politècnica de Catalunya, 2010-06)
Projecte/Treball Final de Carrera
Accés obertEste documento describe un sistema de aprovechamiento de la energía transportada por el oleaje o energía undimotriz. El sistema no transformará la energía únicamente en electricidad si no que aprovecha dicha electricidad ... -
Solution-processed ultrathin SnS 2 -Pt nanoplates for photoelectrochemical water oxidation
(2019-02-20)
Article
Accés obertTin disulfide (SnS2) is attracting significant interest due to the abundance of its elements and its excellent optoelectronic properties in part related to its layered structure. In this work, we detail the preparation of ... -
Tecnología de electromembrana cerámica para la desinfección de aguas
(Universitat Politècnica de Catalunya, 2015-01)
Treball Final de Grau
Accés obertLa difícil tarea en algunos lugares de abastecerse de agua potable ha llevado a los países, empresas y organizaciones gubernamentales a desarrollar una tecnología que permita desinfectar los suministros de agua y que sea ... -
Visible light-driven H2 production over highly dispersed Ruthenia on Rutile TiO2 nanorods
(2016-01)
Article
Accés obertThe immobilization of miniscule quantities of RuO2 (~0.1%) onto one-dimensional (1D) TiO2 nanorods (NRs) allows H2 evolution from water under visible light irradiation. Rod-like rutile TiO2 structures, exposing preferentially ... -
Water splitting reaction on Ce0.15Zr0.85O2 driven by surface heterogeneity
(2016)
Article
Accés obertCe0.15Zr0.85O2 was investigated in the two-step water splitting reaction. High-temperature treatment in N-2 induced compositional and structural heterogeneities which contributed to a six-fold increase of H-2 yield after ...
