Electrochemical valorization of polyethylene terephthalate (PET) waste streams into commodity chemicals offers a potentially sustainable route for creating a circular plastic economy. However, PET wastes upcycling into valuable C2 product remains a huge challenge by the lack of an electrocatalyst that can steer the oxidation economically and selectively. Here, it is reported a catalyst comprising...
Low‐cost and stable sodium‐layered oxides (such as P2‐ and O3‐phases) are suggested as highly promising cathode materials for Na‐ion batteries (NIBs). Biphasic hybridization, mainly involving P2/O3 and P2/P3 biphases, is typically used to boost their electrochemical performances. Herein, a P3/O3 intergrown layered oxide (Na2/3Ni1/3Mn1/3Ti1/3O2) as high‐rate and long‐life cathode for NIBs via tuning...
The oxygen evolution reaction is critical to the efficiency of many energy technologies that store renewable electricity in chemical form. However, the rational design of high‐performance and stable catalysts to drive this reaction remains a formidable challenge. Here, a facile ink‐assisted strategy to construct a series of stable and advanced composite electrocatalysts with single Fe sites for permitting...
Rechargeable Zn/MnO2 batteries using mild aqueous electrolytes are attracting extensive attention due to their low cost, high safety, and environmental friendliness. However, the charge‐storage mechanism involved remains a topic of controversy so far. Also, the practical energy density and cycling stability are still major issues for their applications. Herein, a free‐standing α‐MnO2 cathode for aqueous...
A novel electrochemistry method using stochastic collision of particles at microelectrode to study their performance in single‐particle scale has obtained remarkable development in recent years. This convenient and swift analytical method, which can be called “nanoimpact,” is focused on the electrochemical process of the single particle rather than in complex ensemble systems. Many researchers have...
MoS2 nanosheets as a promising 2D nanomaterial have extensive applications in energy storage and conversion, but their electrochemical performance is still unsatisfactory as an anode for efficient Li+/Na+ storage. In this work, the design and synthesis of vertically grown MoS2 nanosheet arrays, decorated with graphite carbon and Fe2O3 nanoparticles, on flexible carbon fiber cloth (denoted as Fe2O3...
In article number 1700234, Yi‐Lun Ying, Yi‐Tao Long, and co‐workers, demonstrate that a well‐defined silver‐coated nanopore electrode acts as a “rocket” which can electrochemically manipulate silver ions diffused from the tiny opening of the nanopore. As a result, the confining electrochemical effect of the nanopore electrode guides the self‐assembly of AuNPs in the microscale highly homogeneously...
The self‐assembly of nanoparticles is a challenging process for organizing precise structures with complicated and ingenious structures. In the past decades, a simple, high‐efficiency, and reproducible self‐assembly method from nanoscale to microscale has been pursued because of the promising and extensive application prospects in bioanalysis, catalysis, photonics, and energy storage. However, microscale...
