ZnO based-double functional biochar (ZnO-BC) derived pine sawdust is prepared by microwave heating using simple one-pot method for levofloxacin (LEV) and Cr(Ⅵ) removal from wastewater. ZnO-BC has well developed pore structure with BET surface area of 915.47 m 2 /g, which also has well ZnO crystalline. These characteristics make ZnO-BC available as the adsorbent and photocatalyst for LEV and Cr(Ⅵ) removal wastewater. LEV and Cr(Ⅵ) adsorption date fit well with the Hill and Pseudo-second order equation with LEV and Cr(Ⅵ) adsorption amount of 193.42 and 21.03 mg/g, respectively. The LEV and Cr(Ⅵ) adsorption behavior are determined by the chemisorption process. The hydrogen bond, π-π interaction, surface complexation, pore filling are responsible for LEV removal. While the hydrogen bonding, complexation and redox are crucial to the removal of Cr(Ⅵ) from wastewater. LEV removal is 85.72–97.19% at 15–25 mg/L at 120 min, and Cr(Ⅵ) removal is 72.62–99.9% at 40–60 mg/L at 75 min under UV irradiation. The possible photocatalytic mechanisms of the LEV and Cr(Ⅵ) are further investigated and analyzed.

The development of acetone gas sensors is desirable but challenging for both air quality monitoring and medical diagnosis. Herein, starting from bimetallic In/Ga metal–organic frameworks (MOFs) (MIL-68 (In/Ga)), a facile strategy is proposed to couple with zinc ions to design In/Ga oxide (IGO)@ZnO core–shell nanotubes for efficient acetone detection. In such a heterostructure, tiny ZnO nanoparticles are closely decorated on IGO nanotubes, which is beneficial to enlarge the specific surface area and create rich oxygen vacancies and heterojunction interfaces. Benefiting from the structural merits and synergetic effects, the IGO@ZnO-based gas sensor exhibits a low detection limitation (200 ppb), a high response, good linearity relationship between the sensing responses and wide testing acetone concentrations, and fast response and recovery time (6.8/6.1 s) with good selectivity and stability. These sensing performances strongly indicate the practical application to quantitatively detect acetone.

Abstract Sulfonamides are detected in various water environments and threaten aquatic ecosystems. To remove sulfonamides, many previous studies have focused on preparing metal–organic framework-derived carbon materials (MOFs-CMs) applied in persulfate activation. In this study, Fe-based MOFs derived from porous carbon materials were obtained by facile one-pot hydrothermal and pyrolysis. The catalyst can overcome passivation in alkaline environments and showed a high peroxydisulfate (PDS) activation performance. Unlike traditional modifications, ZnO was added during the synthesis process to control the morphology characteristics of the catalyst. FeZn–MOF-CMs in this study displayed a high sulfadiazine removal efficiency of 99.6% in alkaline conditions, and exhibited high resistance to common anions and organic matter. The surface morphology could be controlled by different amounts of ZnO additions and the free radical pathway was the main mechanism in the PDS system. This study provides a facile synthesis method for the preparation of porous carbon materials from Fe-based MOFs. Graphical abstract

Overvoltage protection is becoming increasingly important because of miniaturization and multifunctionality of electronic devices. Flexible, easily processable materials with nonlinear and reversible I–V behavior are highly desired. In this study, hybrid nanoparticles of ZnO-decorated carbon nanotubes (CNT–ZnO) were synthesized via a sol–gel hydrothermal process employed in an epoxy matrix to prepare composites. Microstructure analysis demonstrated that ZnO nanoparticles were well-bonded to the surface of CNT. The CNT–ZnO/epoxy composites exhibited nonlinear I–V behavior under increasingly applied voltage with a nonlinear coefficient of 5.01 (10 wt % filler loading). More importantly, the composites possessed excellent reversibility from dielectric to conductor and vise versa in the recycling of increase and decrease of applied electric field, in contrast to the poor recoverability of pure CNT-filled epoxy. The mechanism of the nonlinear I–V behavior and reversibility was investigated and discussed. A simple circuit was fabricated, which verified well the protection function of the CNT–ZnO/polymer composites.

The amphipathic interface layer sandwiched between cathode and active layers had always played a role to balance interface compatibility and interfacial energy barriers in inverted organic solar cell (OSC) devices. Two functionalized amphiphilic diblock fullerene derivatives named C60-2DPE and C60-4HTPB were synthesized and applied as an interface layer in modifying zinc oxide (ZnO). Based on their amphipathic characteristics, the solvent treatment was introduced to cause an obvious self-assembly of the two materials on ZnO. The introduced cathode buffer layer could improve the interface compatibility between ZnO and the organic active layer effectively with its amphipathic blocks. Based on the PTB7-Th:PC71BM system, the OSC devices with a functionalized fullerene derivative layer could reach a power conversion efficiency of 9.21 and 8.86% for C60-2DPE and C60-4HTPB , respectively.
