It is highly desired but still remains challenging to design and develop a Co-based nanoparticle-encapsulated conductive nanoarray at room temperature for high-performance water oxidation electrocatalysis. Here, it is reported that room-temperature anodization of a Co(TCNQ)<sub>2</sub> (TCNQ = tetracyanoquinodimethane) nanowire array on copper foam at alkaline pH leads to in situ electrochemcial oxidation of TCNQ<sup>-</sup> into water-insoluable TCNQ nanoarray embedding Co(OH)<sub>2</sub> nanop
The successful use of electrochemiluminescence (ECL) in immunoassay for clinical diagnosis requires development of novel ECL signal probes. Herein, we report lanthanide (Ln) metal-organic frameworks (LMOFs) as ECL signal emitters in the ECL immunoassay. The LMOFs were prepared from precursors containing Eu (III) ions and 5-boronoisophthalic acid (5-bop), which could be utilized to adjust optical properties. Investigations of ECL emission mechanisms revealed that 5-bop was excited with ultraviole
A highly attractive, but still a key challenge, is the development of earth-abundant electrocatalysts for efficient NH3 electrosynthesis via the N2 reduction reaction (NRR). In this communication, we report the development of a Mo2N nanorod as a highly efficient and selective NRR electrocatalyst for artificial N2 fixation in acidic electrolytes under ambient conditions. In 0.1 M HCl, this catalyst achieved a high Faradaic efficiency of 4.5% with a NH3 yield of 78.4 μg h-1 mgcat.-1 at -0.3 V vs.
We have proposed a dual-quenching electrochemiluminescence (ECL) strategy which is based on tris(2,2′-bipyridyl)ruthenium(II) [Ru(bpy)32+] as chromophores caged in three-dimensional (3D) zinc oxalate metal–organic frameworks [Ru(bpy)32+/zinc oxalate MOFs] for ultrasensitive detection of amyloid-β (Aβ). The three-dimensional chromophore connectivity in zinc oxalate MOFs provided a network for rapid excited-state energy transfer migration among Ru(bpy)32+ units which shielded the chromophores from
A MoS<sub>2</sub> nanosheet–reduced graphene oxide hybrid behaves as a high-performance and stable catalyst for ambient electrochemical N<sub>2</sub>-to-NH<sub>3</sub> fixation.
