Abstract

Direct fuel cells, such as direct hydrazine fuel cells (DHFC), are considered environmentally friendly alternative energy technologies with great potential for the future. Hydrazine, used as a liquid fuel, is particularly advantageous due to its high cell voltage and energy density. In this study, the electrocatalytic potential of SnZr/ZSM-5 catalysts synthesized with wet impregnation at various molar ratios is investigated for hydrazine oxidation. The catalyst is characterized by XPS, ICP-MS, XRD, FTIR, SEM-EDX, and TEM techniques. Additionally, thermal characterization of this catalyst is performed with temperature-programmed reduction (TPR), temperature-programmed oxidation (TPO), and temperature-programmed desorption (TPD). The catalytic activities of ZSM-5-supported monometallic and bimetallic catalysts are determined using electrochemical measurements such as cyclic voltammetry (CV), chronoamperometry (CA), and electrochemical impedance spectroscopy (EIS) for direct hydrazine fuel cell (DHFC). The highest catalytic activity achieved is 44.874 mA cm−2 for SnZr(50:50)/ZSM-5 catalyst, revealing that Zr addition to Sn improves the electrocatalytic activity of bimetallic catalysts compared to monometallic catalysts. The long-term current density and stability of SnZr(50:50)/ZSM-5 catalyst are taken at 0.6 V. EIS measurements indicated that the lowest charge transfer resistance is at 0.6 V, consistent with CV and CA measurements. SnZr(50:50)/ZSM-5 provides a new perspective as an anode catalyst for DHFC applications.

ZSM-5沸石催化剂在锡和锆催化剂上具有优异的肼电氧化活性
直接燃料电池,如直接联氨燃料电池(DHFC),被认为是未来具有巨大潜力的环境友好型替代能源技术。作为液体燃料的肼由于其高电池电压和能量密度而具有特别的优势。研究了不同摩尔比湿浸渍法制备的SnZr/ZSM-5催化剂对肼氧化的电催化性能。采用XPS、ICP-MS、XRD、FTIR、SEM-EDX和TEM等技术对催化剂进行了表征。此外,通过程序升温还原(TPR)、程序升温氧化(TPO)和程序升温脱附(TPD)对该催化剂进行了热表征。采用循环伏安法(CV)、计时安培法(CA)和电化学阻抗谱(EIS)等电化学测量方法对直接肼燃料电池(DHFC)进行了zsm -5负载的单金属和双金属催化剂的催化活性测定。SnZr(50:50)/ZSM-5催化剂的最高催化活性为44.874 mA cm−2,表明与单金属催化剂相比,添加Zr提高了双金属催化剂的电催化活性。在0.6 V下,测定了SnZr(50:50)/ZSM-5催化剂的长期电流密度和稳定性。EIS测量表明,最低电荷转移电阻为0.6 V,与CV和CA测量结果一致。SnZr(50:50)/ZSM-5为DHFC阳极催化剂的应用提供了新的前景。
