Electric vehicles (EVs) powered by lithium ion batteries (LIBs) or proton exchange membrane hydrogen fuel cells (PEMFCs) offer important potential climate change mitigation effects when combined with clean energy sources. The development of novel nanomaterials may bring about the next wave of technical improvements for LIBs and PEMFCs. If the next generation of EVs is to lead to not only reduced emissions during use but also environmentally sustainable production chains, the research on nanomaterials for LIBs and PEMFCs should be guided by a lifecycle perspective. In this Review, we describe an environmental lifecycle screening framework tailored to assess nanomaterials for electromobility. By applying this framework, we offer an early evaluation of the most promising nanomaterials for LIBs and PEMFCs and their potential contributions to the environmental sustainability of EV lifecycles. Potential environmental trade-offs and gaps in nanomaterials research are identified to provide guidance for future nanomaterial developments for electromobility.

“…Oxygen reduction reaction (ORR) is an important process in an electrochemical energy conversion and a four-electron reaction is desirable to take place for a given catalyst in order to achieve good electrocatalytic performance. In recent years, the transition metals such as Mn [2], Fe [3,4], Co [5], Ni [6], Cu [7] and the heteroatom dopants B [8], N [9,10], P [11,12], S [13,14], Se [15] have been reported to modify the catalytic properties of various carbon materials including amorphous carbon, carbon nanotubes, and graphene, which arouse a great deal of interest for the research and development of non-noble catalysts.…”

Abstract:The carbon supported iron selenide catalysts (FeSe2/C) were prepared with various selenium to iron ratios (Se/Fe), namely, Se/Fe = 2.0, 2.5, 3.0, 3.5 and 4.0, through facile microwave route by using ferrous oxalate (FeC2O4·2H2O) and selenium dioxide (SeO2) as precursors. Accordingly, effects of Se/Fe ratio on the crystal structure, crystallite size, microstructure, surface composition and electrocatalytic activity for oxygen reduction reaction (ORR) of FeSe2/C in an alkaline medium were systematically investigated. The results revealed that all the FeSe2/C catalysts obtained with the Se/Fe ratios of 2.0-4.0 exhibited almost pure orthogonal FeSe2 structure with the estimated mean crystallite sizes of 32.9-36.2 nm. The electrocatalytic activities in potassium hydroxide solutions were higher than those in perchloric acid solutions, and two peak potentials or two plateaus responded to ORR were observed from cyclic voltammograms and polarization curves, respectively. The ORR potentials of 0.781-0.814 V with the electron transfer numbers of 3.3-3.9 at 0.3 V could be achieved as the Se/Fe ratios varied from 2.0 to 4.0. The Fe and Se were presented at the surface of FeSe2/C upon further reduction on FeSe2. The Se/Fe ratios slightly influenced the degree of graphitization in carbon support and the amount of active sites for ORR. OPEN ACCESSCatalysts 2015, 5 1080

“…Therefore, the development of cost-effective and non-noble-metal ORR catalysts with commensurate performance is of considerable interest. In this regard, base metal catalysts, such as Fe [11][12][13][14], Co [15][16][17][18][19], Ni [20] and metal dopants containing N, P, S, B [11,17,21,22] have received considerable attention because of their low cost and natural abundance. Huang et al [20] prepared nickel oxide and carbon nanotube composites as ORR electrocatalysts.…”

In this work, we have synthesized a new type of hybridized composites, Ni-P/ CNT-CNFs, which refers to carbon nanotube (CNT)-hybridized carbon nanofibers (CNFs) through electrolessly plated nickel-phosphorus (Ni-P) alloys. The composites combine the merits of CNTs with high electronic conductivity and CNFs with abundant defect sites via the junction of electrolessly deposited Ni-P. The materials have been extensively characterized by scanning electron microscope, transmission electron microscopy, X-ray diffraction, Brunauer-Emmett-Teller (BET), thermogravimetric analysis and hydrophilicity analysis. Electrochemical evaluations for oxygen reduction reaction (ORR) are carried out in 0.1 M KOH with and without 1 M methanol. In addition to serving as desirable candidates as electrocatalyst supports, the randomly oriented hybridized composites show satisfactory activities to ORR and excellent methanol tolerance in alkaline solutions. This generalized method is applicable for the preparation of a broad range of composite materials with different active components simply by variations in electroless plating bath (for example, copper\cobalt or bimetallic plating).
