Photoelectrochemical hydrogen production with concentrated natural seawater produced by membrane process

Simultaneously photocatalytic treatment of hexavalent chromium (Cr(VI)) and endocrine disrupting compounds (EDCs) using rotating reactor under solar irradiation

“…In our previous studies, various TiO 2 nanotubes were fabricated on Ti substrates with anodizing method for use as photoeletrode for hydrogen production [28][29][30][31] and photocatalyst for water purification [32,33]. In particular, in a previously performed Cr(VI) reduction with TiO 2 nanotubes [34], we focused on establishing a rotating TiO 2 /Ti reactor to enhance reaction performance and investigated the effects of rotating speed and number of TiO 2 /Ti mesh on the Cr(VI) reduction.…”

Tapping hydrogen fuel from the ocean: A review on photocatalytic, photoelectrochemical and electrolytic splitting of seawater

“…Excellent photocurrent densities of 10 and 20 mA.cm -2 could moreover be achieved for applied potentials of 0.7 V and 0.9 V vs. RHE using this system [89]. As a final remark, it is even stated in several studies that salts in seawater could act as an ideal electrolyte if corrosion and scaling issues are solved [70,92,160]. Important parameters are composition, concentration and ionic strength [92].…”

A Short Review on Hydrogen, Biofuel, and Electricity Production Using Seawater as a Medium

“…Nam et al − evaluated PEC performance of TiO 2 photoanodes using natural seawater. H 2 evolution rate of TiO 2 photoanode was ca.…”

“…42 Nam et al suggested that nanocomposite showed high performance when compared to single-phase electrode. The performance was further improved in concentrated seawater electrolyte, 41 because seawater with high total dissolved salts (TDS) favor the rapid ionic transport across the electrode/electrolyte interface. This also offers the potential of using seawater brine from desalination plant as an electrolyte solution for PEC.…”
