The high specific strength and exceptional thermal insulating properties of porous metals make them an ideal choice for aerospace structural components and thermal insulation materials. However, in the space environment, proton irradiation leads to the formation of voids, bubbles, and dislocation loops, significantly compromising their physical and mechanical properties. To date, there has been limited attention to the radiation resistance properties in research related to porous metals. This study conducted proton irradiation experiments with a total dose of 1×1017 ions/cm2 on porous Cu. This study discusses and explains the irradiation-induced damage characteristics on the surface of porous Cu before and after proton irradiation. This provides insights into the radiation damage mechanisms within the porous Cu ligaments and the hydrogen release behavior on the ligament surface. Cascade recoil and collision-induced thermal spike effects modify material defect characteristics and crystal structure. This study elucidates the defect evolution mechanism of porous materials under proton irradiation, offering new insights for the design of other radiation-resistant porous materials as protective materials for future advanced space probes. © 2023, The Authors.

Application of novel nanobubble-contained electrolyzed catalytic water to cleanup petroleum-hydrocarbon contaminated soils and groundwater: A pilot-scale and performance evaluation study

Journal of Environmental Management 2023年 347卷 119058页

作者： Ho, Wing-Sze Lin, Wei-Han Verpoort, Francis Hong, Kun-Liang Ou, Jiun-Hau Kao, Chih-Ming Institute of Environmental Engineering National Sun Yat-Sen University Kaohsiung Taiwan State Key Laboratory of Advanced Technology for Materials Synthesis and Processing Wuhan University of Technology Wuhan China Suzhou Dingdedian Environmental Protection Technology Co. Ltd. Suzhou China

Soil and groundwater contamination caused by petroleum hydrocarbons is a severe environmental problem. In this study, a novel electrolyzed catalytic system (ECS) was developed to produce nanobubble-contained electrolyzed catalytic (NEC) water for the remediation of petroleum-hydrocarbon-contaminated soils and groundwater. The developed ECS applied high voltage (220 V) with direct current, and titanium electrodes coated with iridium dioxide were used in the system. The developed ECS prototype contained 21 electrode pairs (with a current density of 20 mA/cm2), which were connected in series to significantly enhance the hydroxyl radical production rate. Iron-copper hybrid oxide catalysts were laid between each electrode pair to improve the radical generation efficiency. The electron paramagnetic resonance (EPR) and Rhodamine B (RhB) methods were applied for the generated radical species and concentration determination. During the operation of the ECS, high concentrations of nanobubbles (nanobubble density = 3.7 × 109 particles/mL) were produced due to the occurrence of the cavitation mechanism. Because of the negative zeta potential and nano-scale characteristics of nanobubbles (mean diameter = 28 nm), the repelling force would prevent the occurrence of bubble aggregations and extend their lifetime in NEC water. The radicals produced after the bursting of the nanobubbles would be beneficial for the increase of the radical concentration and subsequent petroleum hydrocarbon oxidation. The highly oxidized NEC water (oxidation-reduction potential = 887 mV) could be produced with a radical concentration of 9.5 × 10−9 M. In the pilot-scale study, the prototype system was applied to clean up petroleum-hydrocarbon polluted soils at a diesel-oil spill site via an on-site slurry-phase soil washing process. The total petroleum hydrocarbon (TPH)-contaminated soils were excavated and treated with the NEC water in a slurry-phase reactor. Results show that up to 74.4% of TPH (initial

Electrocatalytic reaction can convert carbon dioxide (CO2) into formic acid (HCOOH), which is considered as a promising pathway for sustainable energy conversion and valuable chemicals production. Nevertheless, CO2 reduction reaction (CO2RR) to HCOOH exists high reaction potential, insufficient active site and low product selectivity. In this review, various catalysts, including metal and metal oxides, metal-organic frameworks, covalent organic frameworks and carbon-based materials, are summarized from the structure-activity relationship between electrocatalysts and CO2RR performance. Then, the regulation strategies of morphology control, defect engineering, and interface engineering, to improve the selectivity and stability of CO2RR have been successively analyzed. In addition, the practical application of CO2RR to HCOOH in electrochemical energy technologies (formic acid fuel cells and water splitting) are comprehensively discussed. Finally, the perspectives and outlook of advanced catalysts for electrochemical selectivity reduction CO2 to HCOOH are thoroughly addressed. This review will be helpful to provide new insights for designing high selective and stable CO2RR to HCOOH electrocatalysts. © 2025 Elsevier B.V.
