Abstract Metal halide perovskites have fascinated the research community over past decade, and demonstrated unprecedented success in optoelectronics. In particular, perovskite single crystals emerged as promising candidates for ionization radiation detection, due to excellent opto-electronic properties. However, most of reported are grown organic solvents require high temperature. this work, we develop a low-temperature crystallization strategy grow CsPbBr 3 water. Then, carefully...
A new potential oxidation process is provided by CuFe2O4/hydroxylamine (HA) system for degradation of antibiotics in water. The CuFe2O4/HA can generate reactive oxygen species (ROS) the sulfamethoxazole (SMX). addition radical scavengers, including benzoquinone (BQ) and catalase (CAT), inhibited SMX system. Electron transfer played a key function generation ROS SMX. main ROS, was superoxide (O2•–) mainly generated from adsorbed (O2(A)), which came lattice (O2–(L)) CuFe2O4. effectively...
Many reagents as electron sacrificers have been recently investigated to induce decomposition of permanganate (KMnO4) produce highly reactive intermediate Mn species toward oxidation organic contaminants; however, this strategy meanwhile causes low KMnO4 utilization efficiency. This study surprisingly found that graphite can mediate direct transfer from organics (e.g., sulfamethoxazole (SMX)) KMnO4, resulting in high efficiency, rather than reductive sites graphite-induced conversion...
Abstract 2D metal‐porphyrin frameworks (MPFs) are attractive for advanced energy storage devices. However, the inferior conductivity and low structural stability of MPFs seriously limit their application as flexible free‐standing electrodes with high performance. Here, first time, an interlayer hydrogen‐bonded MXene/MPFs film is proposed to overcome these disadvantages by intercalation highly conductive MXene nanosheets into via a vacuum‐assisted filtration technology. The alternant...
Abstract Large single crystals serve as an ideal platform for investigating intrinsic material properties and optoelectronic applications. Here we develop a method, namely, room-temperature liquid diffused separation induced crystallization that uses silicone oil to separate the solvent from perovskite precursors, grow high-quality crystals. The growth kinetics of using this method is elucidated, their structural are carefully characterized. resultant crystals, taking CH 3 NH PbBr example,...
Abstract Metal halide perovskite‐based high‐performance X‐ray scintillator is considered as one of the most favorable candidates applied in fields medicine, industry, and science. However, current scilltillators based on perovskites still suffer from issue poor stability, which impedes their further wide applications. Herein, a template assembled method to prepare large‐size, flexible, stable CsPbBr 3 @Polymethyl methacrylate composite films ambient conditions developed detection performance...
Carbon nanotubes (CNTs) and their derivatives have been widely exploited to activate various oxidants for environmental remediation. However, the intrinsic mechanism of CNTs-driven periodate (PI) activation remains ambiguous, which significantly impedes scientific progress toward practical application. Here, we found that CNTs can strongly boost PI oxidation phenols. Reactive oxygen species analysis, in situ Raman characterization, galvanic process experiments, electrochemical tests revealed...
Accelerating the rate-limiting Fe3+/Fe2+ circulation in Fenton reactions through addition of reducing agents (or co-catalysts) stands out as one most promising technologies for rapid water decontamination. However, conventional such hydroxylamine and metal sulfides are greatly restricted by three intractable challenges: (1) self-quenching effects, (2) heavy dissolution, (3) irreversible capacity decline. To this end, we, first time, introduced redox-active polymers electron shuttles to...
Microstructure engineering serves as a potent approach to counteract the mechanical deterioration of Ni-rich layered cathodes, stemming from anisotropic strain during Li+ (de)intercalation. However, pressing challenge persists in devising direct method for fabricating radially aligned cathodes utilizing oriented hydroxide precursors. In this study, we synthesized LiNi0.92Co0.04Mn0.04O2 oxides boasting superior aligned, size-refined primary particles through combination strategic...
Semiconducting polycrystalline thin films are cheap to produce and can be deposited on flexible substrates, yet high-performance electronic devices usually utilize single-crystal semiconductors, owing their superior electrical mobilities longer diffusion lengths. Here we show that the performance of metal-halide perovskites (MHPs) approaches single crystals at room temperature. Combining temperature-dependent terahertz conductivity measurements ab initio calculations uncover a complete...
P2-type layered transition-metal (TM) oxides, NaxTMO2, are highly promising as cathode materials for sodium-ion batteries (SIBs) due to their excellent rate capability and affordability. However, NaxTMO2 is afflicted by issues such Na+/vacancy ordering multiple phase transitions during Na-extraction/insertion, leading staircase-like voltage profiles. In this study, we employ a combination of high Na content Li dual-site substitution strategies enhance the structural stability oxide...
