1High performance of zinc-ferrum redox flow battery with Ac^-/HAc buffer solution显示文摘A green low-cost redox flow battery using Zn/Zn^(2+) redox couple in HAc/NaAc medium and Fe^(2+)/Fe^(3+) redox couple in H_2SO_4 medium was first proposed and investigated for potential stationary energy storage applications. The presence of HAc/NaAc in the negative electrolyte can keep the pH between 2.0 and 6.0even when a large amount of H^+ ions move into negative electrolyte from positive electrolyte through ion exchange membrane. In the pH range of 2.0–6.0, the chemical reaction of Zn species with H^+ species is very insignificant; furthermore, the electroreduction of H^+ ion on the negative electrode is significantly suppressed at this pH range. The zinc-ferrum redox flow battery(Zn/Fe RFB) operated within a voltage window of 0.5–2.0 V with a nearly 90% utilization ratio, and its energy efficiency is around 71.1% at room temperature. These results show that Zn/Fe RFB is a promising option as a stationary energy storage equipment.Zhipeng Xie Qi Su Anhong Shi Bin Yang Baixiong Liu Jianchai Chen Xiaochun Zhou Dingjian Cai Liang Yang 2016Journal of Energy Chemistry2016,25,3:1
2Comparison of UV and UV-LED activated sodium percarbonate for the degradation of O-desmethylvenlafaxine显示文摘As an active metabolite of venlafaxine and emerging antidepressant,Odesmethylvenlafaxine(ODVEN) was widely detected in different water bodies,which caused potential harm to human health and environmental safety.In this study,the comparative work on the ODVEN degradation by UV(254 nm) and UV-LED(275 nm) activated sodium percarbonate(SPC) systems was systematically performed.The higher removal rate of ODVEN can be achieved under UV-LED direct photolysis(14.99%) than UV direct photolysis(4.57%) due to the higher values of photolysis coefficient at the wavelength 275nm.Significant synergistic effects were observed in the UV/SPC(80.38%) and UV-LED/SPC(53.57%) systems and the former exhibited better performance for the elimination of ODVEN.The degradation of ODVEN all followed the pseudo-first-order kinetics well in these processes,and the pseudo-first-order rate constant(kobs) increased with increasing SPC concentration.Radicals quenching experiments demonstrated that both ·OH and CO_(3)·-were involved in the degradation of ODVEN and the second-order rate constant of ODVEN with CO_(3)·-(1.58 × 10^(8)(mol/L)-1sec-1) was reported for the first time based on competitive kinetic method.The introduction of HA,Cl-,NO_(3)-and HCO_(3)-inhibited the ODVEN degradation to varying degrees in the both processes.According to quantum chemical calculation,radical addition at the ortho-position of the phenolic hydroxyl group was confirmed to be the main reaction pathways for the oxidation of ODVEN by·OH.In addition,the oxidation of ODVEN may involve the demethylation,H-abstraction,OH^(-)addition and C-N bond cleavage.Eventually,the UV-LED/SPC process was considered to be more cost-effective compared to the UV/SPC process,although the UV/SPC process possessed a higher removal rate of ODVEN.Jing Deng Anhong Cai Xiao Ling Qian Sun Tianxin Zhu Qingsong Li Xueyan Li Weizhu Chen 2023Journal of Environmental Sciences2023,,4:1
