Designing cost-effective electrocatalysts for electrochemical water splitting to generate the hydrogen energy as a future energy source is pivotal. An excellent catalyst should show high catalytic activity for both hydrogen evolution reaction (HER) and oxy ...
Alkaline anion exchange membrane (AEM) water electrolysis is a promising technology for producing hydrogen using renewable energies. However, current AEM electrolyzers still employ noble-metal-containing electrocatalysts, or have significant overpotential ...
Towards decarbonizing the global economy, hydrogen produced through water electrolysis is expected to be one of the key solutions for variable renewable energy storage and sector coupling, in particular, via the transport sector in the next few decades. Ev ...
Photoelectrochemical (PEC) water splitting is a promising clean route to hydrogen fuel. The best-performing materials (III/V semiconductors) require surface passivation, as they are liable to corrosion, and a surface co-catalyst to facilitate water splitti ...
This article addresses the challenges presented by photoelectrochemical solar fuels technology in a discussion that begins with a functioning device and proceeds to the more fundamental science of its component parts. In this flow of discussion issues are ...
Nowadays, mankind is facing an important energy challenge. Depletion in fossil fuels reserves and increasing energy demand, coupled with the problematic greenhouse effect induced by massive anthropogenic release of carbon dioxide into the atmosphere, are d ...
Water electrolysis is a promising approach to hydrogen production from renewable energy sources. Alkaline water electrolyzers allow using non-noble and low-cost materials. An analysis of common assumptions and experimental conditions (low concentrations, l ...
Process stability is a key operational issue when operating dark fermentation with mixed microbial cultures for hydrogen production. This study aimed at mitigating the instability of hydrogen production by separately adding exogenous pure strains suspected ...
This thesis deals with different aspects of renewable energy transformation and storage concepts and connects them. Although renewable energy installations are growing worldwide, their use is limited by storage technologies. As such, water splitting for hy ...
Heterogeneous electrochemical phenomena, such as (photo)electrochemical water splitting to generate hydrogen using semiconductors and/or electrocatalysts, are driven by the accumulated charge carriers and thus the interfacial electrochemical potential grad ...
