Membraneless unbuffered seawater electrolysis for pure hydrogen production using PtRuTiOx anode and MnOx cathode pairs

Nan -Nan Liang et al.

Summary: This study proposes a membraneless electrolysis method for producing high-purity hydrogen from undisturbed, unbuffered seawater. A ternary Pt, Ru, and Ti catalyst is used to drive chloride oxidation reaction (ClOR) with a high Faradaic efficiency (FE) of approximately 100% in saline water. The chlorine reduction reaction (ClRR) is also inhibited, allowing for hydrogen evolution reaction (HER) even in the presence of chlorine species. The PRT anode/MnOx cathode pair demonstrates similar high FEs for ClOR and HER in seawater electrolysis.

Low-Pt supported on MOF-derived Ni(OH)(2) with highly-efficiently electrocatalytic seawater splitting at high current density

Jianpeng Sun et al.

Summary: A novel MOF derived Pt2/Ni(OH)(2)/NF catalyst with nanosheet-nanoparticle structure was developed, exhibiting excellent catalytic activity in seawater splitting. The catalyst achieved an overpotential of 19 mV at 10 mA.cm(-2), outperforming commercial Pt/C. The study sheds light on the rational construction of robust seawater-based electrocatalysts for seawater splitting.

Electrochemical simultaneous treatment approach: Electro-reduction of CO2 at Pt/PANI@ZnO paired with wastewater electro-oxidation over PbO2

Sina Khalili et al.

Summary: The electro-reduction of CO2 paired with wastewater electro-oxidation processes is a promising method for producing value-added products and decreasing energy consumption. In an H-type cell, the electrocatalytic mineralization of AMD 10B in an aqueous medium over novel beta-PbO2 anode paired with the CO2 electrocatalytic reduction converts to methanol and formic acid at Pt/PANI@ZnO cathode. The proposed anode electrode showed a very high surface-to-volume ratio, high-performance electrocatalytic degradation, and a long service lifetime.

MaO and Mn(OH)2 thin films prepared by the SILAR method and their CO2 photocatalytic performance

M. R. Alfaro Cruz et al.

Summary: CO2 photoconversion to solar fuels requires materials with high affinity to CO2, such as MgO and Mg(OH)(2) films. In this study, the SILAR method was used to prepare MgO/Mg(OH)(2) films on glass substrates at lower temperatures, and the films were tested as photocatalysts for CO2 conversion. The results showed that the chemical composition and structure of the films affected their photocatalytic activity.
