    • Characterization of membranes in non-steady state 

      Rogovyk, Vitaliy (Universitat Politècnica de Catalunya, 2019-05-28)
      Bachelor thesis
      Open Access
      Ion 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 ...
    • Electrocatalytic production of hydrogen boosted by organic pollutants and visible light 

      Soler Turu, Lluís; Macanás de Benito, Jorge; Muñoz Tapia, Maria; Casado Giménez, Juan (2006-01)
      Article
      Restricted access - publisher's policy
      A 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 

      Valderrama Angel, César Alberto (Springer, 2016)
      Part of book or chapter of book
      Restricted access - publisher's policy
      High-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 

      Valderrama Angel, César Alberto (Springer, 2016)
      Part of book or chapter of book
      Restricted access - publisher's policy
      High-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 

      Pi Amorós, Gabriel (Universitat Politècnica de Catalunya, 2010-06)
      Master thesis (pre-Bologna period)
      Open Access
      Este 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 

      Zuo, Yong; Liu, Yongpeng; Li, Junshan; Du, Ruifeng; Yu, Xiaoting; Xing, Congcong; Zhang, Ting; Yao, Liang; Arbiol, Jordi; Llorca Piqué, Jordi; Sivula, Kevin; Guijarro, Néstor; Cabot Codina, Andreu (2019-02-20)
      Article
      Open Access
      Tin 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 

      Gomilla Villalonga, Joan Jose (Universitat Politècnica de Catalunya, 2015-01)
      Bachelor thesis
      Open Access
      La 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 

      Thuy Duong, Nguyen-Phan; Luo, Si; Vovchock, Dimitriy; Llorca Piqué, Jordi; Graciani, Jesus; Fernandez Sanz, Javier; Sallis, Shawn; Xu, Wenquian; Bai, jianming; Piper, Louis F. J.; Polyansky, Dmitri E.; Fujita, Etsuko; Senanayake, S. D; Stacchiola, Dario J. (2016-01)
      Article
      Open Access
      The 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 

      Pappacena, Alfonsina; Boaro, Marta; Armelao, Lidia; Llorca Piqué, Jordi; Trovarelli, Alessandro (2016)
      Article
      Open Access
      Ce0.15Zr0.85O2 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 ...
