2020年9月1日 · In this work, a novel Fe-hemin-MOFs with unique peroxidase-like activity was proposed for the first time. Hemin could mimic inartificial enzymes of high electrocatalytic activity and the coordination structure of hemin-MOFs can protect the hemin active center to …

2016年11月4日 · Herein, a smart porous material, Cu-hemin metal-organic-frameworks (Cu-hemin MOFs), was synthesized via assembling of Cu 2+ with hemin to load glucose oxidase (GOD) for electrochemical...

2019年2月6日 · The crystalline nature of free hemin and hemin nanoparticles was confirmed by XRD. As illustrated in Fig. 4d, the XRD patterns of free hemin displayed several relatively strong reflection peaks at 2θ = 6.8, 9.6, 11.5, 16.2, 21.5, and 23.9°. The characteristic peaks of the sphere-shaped nanoparticles were the same as those of free hemin, thus ...

2022年5月31日 · By varying peptoid side chain chemistry to tailor the microenvironment of active sites, these self-assembled peptoid/hemin nanomaterials (Pep/hemin) exhibit highly modulable catalytic...

2024年9月27日 · The XRD patterns of both hemin and γ−CD exhibit a series of distinct sharp diffraction peaks, suggesting that they possess crystalline structures . The obvious characteristic peaks of hemin at 2θ° were 7.96°, 11.39° and 28.03°, while γ−CD had several continuous diffraction peaks at 2θ = 10°~30°, and its characteristic peaks were 5 ...

2002年1月28日 · The mechanochemical reactions of hemin with fluorides (LiF, NaF, KF, CsF, NH 4 F and AgF) were monitored using X-ray diffraction (XRD), and IR and Mössbauer spectroscopies. LiF and NaF were found inert when milled with hemin, however KF, CsF, NH 4 F and AgF react at both hemin sites.

In this work, sub‐nanometer Co clusters anchored on porous nitrogen‐doped carbon (C─N─Co NCs) are successfully prepared by high‐temperature annealing and pre‐fabricated template strategies for...

2023年6月12日 · X-ray diffractogram (XRD) analysis was used to determine the structure and size of the crystal. Figure 1e illustrates the XRD pattern of the bare Fe 3 O 4-MWCNT@Hemin nanohybrid.

2023年4月21日 · 研究通过将铁卟啉氯化血红素（hemin）通过球磨方法负载到碳纳米管（CNTs）上，制备得CNTs-hemin催化剂，用于过一硫酸盐（PMS）体系降解磺胺噻挫（STZ）的降解，可5 min内实现97.8%的STZ的降解。 在本研究中，负载后的hemin对STZ的降解比未负载的活性提高了650倍。...

Herein, a one‐pot facile method to synthesize hemin covalently functionalized carbon nanobranch (CN‐hemin) via direct pyrolysis of citric acid and covalent coupling of hemin to the formed ...
