一氧化碳疗法已成为一种很有前途的癌症治疗方法.选择合适的纳米载体来运送CO供体羰基锰（MnCO）,同时调节CO释放并补偿肿瘤微环境中的过氧化氢和酸度,是提高CO疗法治疗效果的关键.本研究以介孔聚多巴胺（MPDA）为纳米载体,负载MnCO以及含葡萄糖氧化酶的沸石咪唑框架-8 （GOx@ZIF-8）,设计并合成了一种肿瘤微环境响应型核壳结构级联纳米反应器.该纳米反应器进入癌细胞后, GOx@-ZIF-8保护壳会响应酸性肿瘤环境而降解,释放GOx. GOx催化内源性葡萄糖转化为葡萄糖酸和H2O2,加速肿瘤细胞的能量匮乏.该过程反过来又促进了MnCO和H2O2之间的反应,导致CO的原位释放.此外,MPDA的优异光热特性使光热疗法成为可能.这种全面的抗肿瘤策略是CO癌症治疗领域一项很有前景的突破.

Methane, an abundant one-carbon(C_(1)) resource, is extensively used in the industrial production of vital fuels and value-added chemicals. However, current industrial methane conversion technologies are energy-and carbon-intensive, mainly due to the high activation energy required to break the inert C–H bond, low selectivity, and problematic side reactions, including CO_(2)emissions and coke deposition. Electrochemical conversion of methane(ECM) using intermittent renewable energy offers an attractive solution, due to its modular reactor design and operational flexibility across a broad spectrum of temperatures and pressures. This review emphasizes conversion pathways of methane in various reaction systems, highlighting the significance and advantages of ECM in facilitating a sustainable artificial carbon cycle. This work provides a comprehensive overview of conventional methane activation mechanisms and delineates the complete pathways of methane conversion in electrolysis contexts. Based on surface/interface chemistry, this work systematically analyzes proposed reaction pathways and corresponding strategies to enhance ECM efficiency towards various target products, including syngas, hydrocarbons, oxygenates, and advanced carbon materials. The discussion also encompasses opportunities and challenges for the ECM process, including insights into ECM pathways, rational electrocatalyst design, establishment of benchmarking protocols, electrolyte engineering, enhancement of CH4conversion rates, and minimization of CO_(2)emission.

Developing effective and stable photocatalysts for organic pollutants degradation are still a big challenge in practical water treatment now. In this work, La doped ZnO–TiO2composite（La/ZnO–TiO2） were successfully fabricated by using PVP modified ZIF-8/TiO2as template via the absorption and pyrolysis routes. All as-fabricated materials were analyzed by XRD, SEM, TEM, BET, XPS, UV–vis absorption spectra and ESR spectra. PVP modified ZIF-8/TiO2was fully transferred into ZnO–TiO2after being pyrolyzed at high temperature under air *** doping of La can make ZnO–TiO2exhibiting red-shifted, which is attributed to the capture of photo-generated electrons by La, leading to the effective separation between photo-generated electrons and holes. Furthermore,the photocatalytic performance of all as-fabricated materials were explored by degradation of tetracycline（TC）solution under UV light irradiation. La/ZnO–TiO2exhibits excellent stability. And the photocatalytic degradation rate of La/ZnO–TiO2is 99.2%, which is even higher than ZnO（87.4%）, ZnO–TiO2（87.4%）, P25（TiO2）(92.7%).More than that, the effect of catalyst's dose, effect of TC concentration and effect of pH for TC degradation have been well explored. The excellent photocatalytic performance of La/ZnO–TiO2makes it possible to be applied for degradation of organic pollutants in practice.
