Comprehensive Chlorine Suppression: Advances in Materials and System Technologies for Direct Seawater Electrolysis

Nano-Micro Letters, Journal Year: 2025, Volume and Issue: 17(1)

Published: Jan. 22, 2025

Abstract Seawater electrolysis offers a promising pathway to generate green hydrogen, which is crucial for the net-zero emission targets. Indirect seawater severely limited by high energy demands and system complexity, while direct bypasses pre-treatment, offering simpler more cost-effective solution. However, chlorine evolution reaction impurities in lead severe corrosion hinder electrolysis’s efficiency. Herein, we review recent advances rational design of chlorine-suppressive catalysts integrated systems architectures chloride-induced corrosion, with simultaneous enhancement Faradaic efficiency reduction cost. Furthermore, directions are proposed durable efficient systems. This provides perspectives toward sustainable conversion environmental protection.

CO-Tolerant Pt₁-MoO_x/Mo₂N Catalyst for Efficient Activation of C–H and O–H Bonds toward Alcohol Dehydrogenation

Journal of the American Chemical Society, Journal Year: 2025, Volume and Issue: unknown

Published: April 7, 2025

Excessively strong adsorption of CO onto a Pt-based catalyst results in the poisoning effect during numerous CO-containing catalysis reactions, including dehydrogenation process alcohols. Traditional strategies via modifying electronic state Pt atoms are beneficial for weakening adsorption; however, they normally detrimental to C-H cracking, thereby degrading catalytic efficiency toward alcohol reaction. In this work, we present synergistic function Pt1 single and heterostructured MoOx/Mo2N efficiently dehydrogenating alcohols, allowing high resistance along with excellent capacity O-H activation. This conjunction renders electron transfer Pt-MoOx/Mo2N interaction thus induces low 5d occupancy sites, enabling facile desorption, which boosts entire reaction cycles. Based on situ structural characterizations isotopic labeling analysis, found that spontaneously formed thin MoOx-Ov layer enables barrierless breakage bonds even at as room temperature, further energetically facilitates cracking interfacial sites. Therefore, strategy can be applied fabricate CO-tolerant catalysts reactions without compromising reactivity by coupling advantages single-atom defective support materials.

Promotional Role of Pd Over Ni Catalyst Dispersed Over Sc‐ZrO₂ for Methane Partial Oxidation: Crystallinity and Reducibility Effects

Energy Science & Engineering, Journal Year: 2025, Volume and Issue: unknown

Published: May 25, 2025

ABSTRACT Natural emissions of the highly potent greenhouse gas methane cannot be completely prevented, but in presence O 2 , can catalytically converted to hydrogen‐rich syngas. This reaction is specified as partial oxidation (POM). Herein, Ni dispersed over “scandia‐stabilized‐zirconia” (5Ni/DSZ) and promotional effect Pd (0.01 0.1 wt%) are investigated for POM characterized with surface area porosity measurements, X‐ray diffraction, Raman spectroscopy, temperature‐programmed studies, thermogravimetry. During POM, initial population active sites decreases non‐promoted catalysts due under oxygen, upon loading 0.02 wt.% 5Ni/DSZ, site preserved against oxygen during improved metal support interaction between long‐range order crystallites (like cubic ZrO orthorhombic Sc Zr 5 13 ). 5Ni0.02 Pd/DSZ catalyst acquired more than 80% catalytic activity (CH 4 conversion H yield) 2.5 /CO ratio at 600°C 240 min on stream. The also maintained 70% yield ~2 30 h time thermostable may recommended syngas production high ‐yield through POM.
