We report α‐MoO3 flowers as a highly effective organics adsorbent for the first time. With α‐MoO3 microfibers (MFs), α‐MoO3 flowers uniformly self‐assemble on a carbon cloth, serving as a great organics scavenger. They not only provide a high specific surface area but also possess van der Waals force, both of which guarantee a high adsorption efficiency for multiple organics. Nearly 100% of Rhodamine B (RhB), methylene blue (MB), and crystal violet (CV) are rapidly adsorbed while flowing through the designed α‐MoO3 flower‐based filtration device. Even after five recycling times, its high adsorption efficiency toward RhB remains unaffected. The adsorption capacity of α‐MoO3 flowers for RhB, MB, and CV reaches up to 4974, 6217, and 3886 mg/m2, respectively. Additionally, this novel adsorbent can adapt to a wide pH range, maintaining the excellent capacity of 4774 and 4473 mg/m2 toward RhB at pH of 2.0 and 12.0. The α‐MoO3 flowers can also adsorb other organics, including MO, noroxin, and tetracycline hydrochloride. Moreover, the free‐standing α‐MoO3 flowers on a carbon cloth realize the adsorptive filtration for organics removal, which not only require no conditions and no energy consumption but also avoid secondary pollution to the water as compared to the powdery adsorbents.

The fast developing electronic industry boosts higher demand of transparent electrode. Nanofiber network design provides a new platform for finding alternative materials to replace the traditional indium-doped tin oxide (ITO) film as transparent electrode. In this work, the TiN nanofiber network with a micron-scale precise geometry was firstly assembled by solution electrowriting. Unlike the ordinary opaque TiN film or bulk, the geometry patterned TiN nanofiber network achieved an ultrahigh transparency above 90%. Due to the electrical conductive virtue of TiN, the network reached a relatively low sheet resistance of 10.3 Ω/sq that can be comparable to ITO and even metal nanofibers. The combination of high transparency and low sheet resistance in TiN nanofiber network paves a way for its application as transparent electrode. Moreover, the figure-of-merit of TiN nanofiber transparent electrode was controllable by simply adjusting the geometry size of TiN nanofiber pattern. A series of oxidation resistance and corrosion resistance tests were additionally carried out, which caused little effect on the performance of TiN nanofiber transparent electrode. This excellent antioxidative and anticorrosive property demonstrates the high chemical durability of TiN nanofiber network, especially compared to metal nanofiber networks.
