The ZnFe2O4@PE serves multiple purposes. Firstly, it effectively reduces the local current density, thereby mitigating the drastic volume changes that occur during charging and discharging. Additionally, the nano-ZnFe2O4 possesses a favorable affinity for lithium ions, facilitating...
以ZnTA@Zn为负极组装Zn-I2电池时,电池的库伦效率可达到95.5%,起始放电容量为201.5 mAh g-1,高于裸锌为负极时的库伦效率(82.5%)和放电容量(174 mAh g-1)。在长循环实验测试中,以ZnTA@Zn为负极的Zn-I2电池可在4 A g-1电流密度...
近日,北京化工大学/延安大学徐斌教授与西安科技大学刘欢教授携手合作,在国际知名期刊 ACS Nano 发表了题为“Zn and Cl Coregulated MXene Catalyst Enhances Li-CO2Battery Reversibility”的研究论文,博士生田雪为本文第一作者。该研究运...
Maximum leaf N (3.97%), leaf P (0.36%), leaf K (1.97%) and fruit N (3.49%), fruit P (0.28%) and fruit K (1.67%) content were also recorded through nano-Zn application compared to other Zn analogues. Both in leaf and fruit samples, Zn content was directly correlated to nano-Zn...
摘要: 本研究旨在研究日粮纳米ZnOs(nano-ZnOs)对断奶仔猪生长性能、腹泻率、矿物质沉积(锌、铁和锰)、肠道形态和屏障的影响。将384只断奶仔猪(Duroc×Landrace×Yorkshire)分为4组,饲喂添加0、400和800 mg/kg的nano-ZnOs或3000 mg/kg的ZnO的基础日粮14天。与对照... 查看全部>> ...
理论计算证明，从Zn到Cu的电子传输促进了关键中间体(*CO和*NH2)的形成，降低了*CO和*NH2的耦合能垒，提高了尿素电合成的催化性能。 Oxide-Derived Core-Shell Cu@Zn Nanowires for Urea Electrosynthesis from Carbon Dioxide and Nitrate in Water. ACS Nano, 2022. DOI: 10.1021/acsnano.2c01177 ...
因此,Gly-定制的EDL有助于提高Zn金属负极在高pH-碱性电解质体系中的可充电稳定性。 Adaptive Ionization-Induced Tunable Electric Double Layer for Practical Zn Metal Batteries over Wide pH and Temperature Ranges.ACS Nano,2023, DOI: ht-tps://http://....
从而导致在ORR方面具有出色的电化学性能。总之，研究结果表明N4第一配位壳与第二配位球内的空位之间存在协同相互作用，从而提高了稳定性和催化效率。Vacancy-Enhanced Sb-N4 Sites for the Oxygen Reduction Reaction and Zn-Air Battery. Nano Lett., 2024, DOI: 10.1021/acs.nanolett.4c00808.
因此,碳材料与MnO2的复合被认为是优化水性锌-MnO2电池正极性能的重要途径之一。目前,与二氧化锰复合的碳材料主要是基于碳纳米纤维、碳纳米管等传统的商业化材料,利用可再生廉价生物质废弃物碳源提高MnO2性能的研究仍然较少。因此,探索可持续、可再生生物质资源在水系Zn-MnO2电池的应用意义重大。
