二氧化碳电还原的电解质研究进展

基于可再生能源电力将二氧化碳电化学还原（CO₂RR）为高价值化学品是实现二氧化碳资源化利用的有效途径。催化剂和电解质组分对界面微环境的调控共同决定了CO₂RR的催化性能。尽管在高性能催化剂的设计及制备方面已取得了实质性进展,但电解质组分对界面局部催化环境的影响,以及对CO₂RR反应过程的优化机理还未得到充分认识。综述了电解质组分对CO₂RR界面微环境调控的研究进展,重点围绕电解质中阳离子、阴离子、溶剂、配体以及添加剂等开展讨论,包括电解质组分对界面化学环境的影响,如界面电场、局部pH、偶极-场作用和界面水结构等,揭示电解质调控的反应机理,以及在改善催化性能中的重要作用。本文从电解质调控角度出发,为设计高催化性能电解体系提供新的研究思路,推动CO₂RR领域发展。

Immobilization of horseradish peroxidase in three-dimensional macroporous TiO2 matrices for biosensor applications

Three-dimensional macroporous TiO₂ was synthesized by a sol-gel procedure using polystyrene colloidal crystals as templates. SEM showed that a face-centered cubic (FCC) 3D macroporous structure was obtained. Horseradish peroxidase (HRP) was successfully immobilized on the surface of an optically transparent electrode (OTE). Photoelectrochemical properties were characterized using a three electrodes system and an ultraviolet lamp. The HRP/TiO₂/OTE displays a rapid photocurrent response, approximately 178.7 nA, under UV illumination (380 nm). The sensitivity of H₂O₂ detection was 70.04 μA/mM without UV illumination, and it increased to 102.97 μA/mM when illuminated by UV. The amperometric response was also enhanced. The high response was due to the good biocompatibility of TiO₂ and excellent photoelectrical property and the large effective surface of the three-dimensionally ordered macroporous structure.     

The Mechanism of (R,R) ZX-5 on Increasing NO Release

(R,R) ZX-5 has been proven to have positive effects on choroidal blood flow without affecting the sclera and ciliary bodies in New Zealand white rabbits. This study was designed to investigate the mechanisms of (R,R) ZX-5 on improving the choroidal blood flow and promoting NO production. HUVECs (human umbilical vein endothelial cells) were used to determine the production of eNOS, p-eNOS, AKT and Erk1/2 by Western blot analysis. iNOS and eNOS mRNA levels were investigated by RT-PCR and the effect of (R,R) ZX-5 on NO production were determined by eNOS activity assay. We found (R,R) ZX-5 upregulated protein expression of eNOS and iNOS, increased NO production, and reduced ERK and Akt protein level. Therefore, (R,R) ZX-5 may promote the choroidal blood flow in New Zealand white rabbits without affecting the blood flow in the iris or ciliary bodies via increasing NO production. These results suggest that (R,R) ZX-5 may function to cure and prevent Age-related macular degeneration (AMD).
