AbstractStructural reconstruction of electrocatalysts plays a pivotal role in catalytic performances for CO2 reduction reaction (CO2RR), whereas the behavior is by far superficially understood. Here, we report that CO2 accessibility results in a universal self-adaptive structural reconstruction from Cu2O to Cu@CuxO composites, ending with feeding gas-dependent microstructures and catalytic performances. The CO2-rich atmosphere favors reconstruction for CO2RR, whereas the CO2-deficient one prefers that for hydrogen evolution reaction. With the assistance of spectroscopic analysis and theoretical calculations, we uncover a CO2-induced passivation behavior by identifying a reduction-resistant but catalytic active Cu(I)-rich amorphous layer stabilized by *CO intermediates. Additionally, we find extra CO production is indispensable for the robust production of C2H4. An inverse correlation between durability and FECO/FEC2H4 is disclosed, suggesting that the self-stabilization process involving the absorption of *CO intermediates on Cu(I) sites is essential for durable electrolysis. Guided by this insight, we design hollow Cu2O nanospheres for durable and selective CO2RR electrolysis in producing C2H4. Our work recognizes the previously overlooked passivation reconstruction and self-stabilizing behavior and highlights the critical role of the local atmosphere in modulating reconstruction and catalytic processes.

Facile preparation of chlorine-functionalized N-conjugated polymer for the enhancement of elemental mercury oxidation

The enhancement of elemental mercury catalytic oxidation allows to reduce the formation of residual adsorbed mercury species on the catalyst surface and to simplify the subsequent wet desorption process of deactivated catalysts.Here we proposed one mechanochem. approach to anchor reactive chlorine groups on the nitrogen-containing conjugated polymer (m-CN-Cl) surface, facilitating efficient oxidation of Hg⁰.In this proof-of-concept design, the C-Cl functional group was highly distributed on the surface of the graphitic phase carbon nitride (g-C₃N₄, CN) substrate and exhibited excellent Hg⁰ oxidative removal performance in the temperature window of 60-180°.The Hg⁰ removal capacity of m-CN-Cl reached 2.72 mg/g at a breakthrough ratio of 63% without reaching the saturation limit, which exceeded the sample prepared by impregnation (i-CN-Cl) and most halogen-modified activated carbon absorbents.In the presence of H₂S, the Hg⁰ catalytic oxidation by m-CN-Cl converted to adsorption and formed the adsorbed HgS, owing to the preferential reaction of the C-Cl group with H₂S to generate underactive nascent sulfur sites. 71.7% of the adsorbed mercury species (56.89% of the total removed mercury) on the m-CN-Cl surface could be desorbed into 1 mol/L HCl solution within 30 min.XPS tests and DFT calculations showed that the C-Cl functional group was the predominant oxidation center, with an adsorption energy up to -254.74 kJ/mol for Hg⁰.The mechanochem. chlorine-modified g-C₃N₄ provided an avenue to active Cl site anchorage on the substrate surface and modulation of surface mercury species and offered a promising solution for mercury removal by catalytic oxidation

Tannic acid-metal interlayers enhance permeance and antibiotics/NaCl separation efficiency of polyamide nanofiltration membranes

Author: Wen, Yuehao ; Wang, Jingquan ; Guo, Hongguang ; Zhou, Jianfei

The assembly of metal ions and phenols has been widely exploited for surface modification of materials.In this work, polyamide (PA) composite nanofiltration membranes with different types of tannic acid-metal (TA/Mⁿ⁺) interlayers were fabricated.TA/transition metal interlayers endowed the PA composite membranes with enhanced water permeability and improved separation of antibiotics from NaCl.Among various TA/Mⁿ⁺-PA membranes, TA/Al³⁺-PA membrane possessed increased pore size, augmented surface roughness, and reduced neg. potential, exhibiting the most outstanding performance with a high-water flux of 8.94 L·m^-2·h^-1·bar^-1 (429% enhancement compared to PA membrane) and an excellent selective factor of 9.75 (589% improvement over the PA membrane) for ciprofloxacin (CIP) and NaCl, successfully breaking the trade-off between permeability and selectivity.Moreover, this membrane displayed 89.92% Na₂SO₄ rejection and 94.10% CIP rejection in the CIP/Na₂SO₄ mixtureIn addition, the TA/Mⁿ⁺-PA membranes presented superior anti-fouling ability compared to the PA membrane.This study aims to explore the effects of different TA-metal interlayers on the performance of PA composite membranes and the underlying mechanisms, thereby offering more effective guidance for the application of such interlayered composite membranes.
