一维(1D)铂基电催化剂对氧还原反应(ORR)展现出了良好的催化活性和稳定性。基于一维铂基纳米结构阵列的三维(3D)有序电极的研究进展表明,它们在解决现有铂/碳(Pt/C)纳米颗粒电极在高性能质子交换膜燃料电池(PEMFC)的传质特性和持久性挑战方面具有巨大的潜力。本文综述了该领域的最新进展,重点介绍了基于独立的铂纳米线阵列的三维有序结构电极,讨论了纳米结构薄膜(NSTF)催化剂以及沉积在聚合物纳米线、碳和二氧化钛纳米管阵列上的铂基纳米颗粒电极,并回顾了铂基纳米管阵列电极的研究进展。本文指出了一维催化剂纳米结构的尺寸、表面性质和分配控制的重要性。最后,讨论了一维纳米结构阵列电极在增大电化学比表面积(ECSA)和氧传质阻力定量研究方面面临的挑战和未来的发展机遇。

氯酚(CP)是一类重要的难降解污染物,对人类和其他生物具有高度毒性。电活性膜(REM)通过穿流式操作,能够强化对流传质,在电化学去除难降解污染物过程中彰显出巨大潜力。然而相关研究通常报道的是实验室规模,无法直接保证REM反应器在工程化放大中的成功运行。本研究证明了由亚氧化钛陶瓷阳极和不锈钢阴极配置的同轴管式电极(TCE)可用于大规模的CP 去除。理论和试验结果均表明,TCE构型不仅使电极表面处处正交于电场线,而且具有与电极长度成反比的欧姆电阻。此外,TCE构型可根据废水流动方向将从阳极流向阴极(AC模式)调整为从阴极流向阳极(CA模式),为CP的选择性降解创造了可控条件。单程穿流实验结果证实在CA模式下,2,4-二氯苯酚(2,4-DCP)的去除动力学常数较AC模式高一个数量级,2,4-DCP 和化学需氧量(COD)去除率分别为98%和72.5%。理论计算和实验结果表明,CA模式具有较低的反应活化能和自由能。在不增加欧姆电阻或降低活性面积的情况下,TCE构型适用于组件化策略来放大电化学反应器规模。使用三个TCE组件时,2,4-DCP的去除率达到99.4%,能耗为1.5 kW⋅h⋅m−3。本研究为REM反应器提出了一种合理的电极构型设计,为电化学去除氯酚类污染物在跨越面向工程放大的“死亡之谷”提供有效策略。

Robustness in most of the literature is associated with min-max or min-max regret criteria. However, these criteria of robustness are conservative and therefore recently new criteria called, lexicographic α-robust method has been introduced in literature which defines the robust solution as a set of solutions whose quality or jth largest cost is not worse than the best possible jth largest cost in all scenarios. These criteria might be significant for robust optimization of single objective optimization problems. However, in real optimization problems, two or more than two conflicting objectives are desired to optimize concurrently and solution of multi objective optimization problems exists in the form of a set of solutions called Pareto solutions and from these solutions it might be difficult to decide which Pareto solution can satisfy min-max, min-max regret or lexicographic α-robust criteria by considering multiple objectives simultaneously. Therefore, lexicographic α-robust method which is a recently introduced method in literature is extended in the current research for Pareto solutions. The proposed method called Pareto lexicographic α-robust approach can define Pareto lexicographic α-robust solutions from different scenarios by considering multiple objectives simultaneously. A simple example and an application of the proposed method on a simple problem of multi objective optimization of simple assembly line balancing problem with task time uncertainty is presented to get their robust solutions. The presented method can be significant to implement on different multi objective robust optimization problems containing uncertainty.
