“…For example, Pd-based nanoscale catalysts offer great promise for fuel-cell reactions 72 and the cost of Pd is one-fifth of the cost of Pt. Core-shell structures consisting of an inexpensive metal or alloy at the core and Pt on the outer shell could also reduce catalyst cost.…”

The creation of a sustainable energy generation, storage, and distribution infrastructure represents a global grand challenge that requires massive transnational investments in the research and development of energy technologies that will provide the amount of energy needed on a sufficient scale and timeframe with minimal impact on the environment and have limited economic and societal disruption during implementation. In this opinion paper, we focus on an important set of solar, thermal, and electrochemical energy conversion, storage, and conservation technologies specifically related to recent and prospective advances in nanoscale science and technology that offer high potential in addressing the energy challenge. We approach this task from a two-fold perspective: analyzing the fundamental physicochemical principles and engineering aspects of these energy technologies and identifying unique opportunities enabled by nanoscale design of materials, processes, and systems in order to improve performance and reduce costs. Our principal goal is to establish a roadmap for research and development activities in nanoscale science and technology that would significantly advance and accelerate the implementation of renewable energy technologies. In all cases we make specific recommendations for research needs in the near-term (2-5 years), mid-term (5-10 years) and long-term (>10 years), as well as projecting a timeline for maturation of each technological solution. We also identify a number of priority themes in basic energy science that cut across the entire spectrum Broader contextA major scientific and societal challenge of the 21st century is the conversion from a fossil-fuel-based energy economy to one that is sustainable. The energy challenge before us differs in three ways from past large scale challenges: the first is the large magnitude and relatively short time scale of the transition (a predicted doubling of energy demand by mid-century and a tripling by the end of the century); the second is the need to develop CO 2 -neutral, renewable energy sources; and the third is the cost-competitive aspect of the transition (insofar as the cost of energy to the consumer must be competitive with the fossil fuel energy supply being replaced). What is clear is that the science and engineering research communities working with industry, and policy makers (government, economists, social scientists) will have to educate the citizenry and get them to function collaboratively and globally to enhance the quality of life and to preserve the environment of our planet for future generations. Our team has prepared a technical article on the role of nanotechnology in our energy future aimed at guiding both our own community of scientists and engineers and our policy makers who interface with the public.

“…Advantages of ethanol include the fact that it is nontoxic and is readily available as liquor. The use of the DEFC as a clean power source has been demonstrated, but the difficulties in enhancing electrochemical oxidation during proton generation even from methanol at the MEA (membrane electrode assembly) have been discussed in several papers [1,2]. There are still several problems associated with the fuel for the DEFC.…”

A new process for silica nano-powder dispersion in an anode electrode paste for direct ethanol fuel cells was studied by applying an excess amount of solvent (acetone) that easily evaporates after mixing the paste. A well-dispersed anode electrode results in more efficient output power than an agglomerated anode paste. Nano-silica will act as an oxidant to acetaldehyde and can form a structure that supports increased ethanol penetration into the electrode. Using gas chromatography, the acetaldehyde concentration was measured to determine the mechanism of the reaction occurring in the fuel cells.

“…In case of direct methanol fuel cell (DMFC), cathode catalysts require methanol tolerance and ORR results due to the methanol transfer from anode to cathode. 22 The reaction of cathode catalyst with transferred methanol hinders the ORR reactivity. The methanol oxidation of Pd-NiHCF NPs and Pt NPs has been shown by ORR in 0.1 M HClO 4 mixed with 0.1 M CH 3 OH ( Figure 5).…”

Nickel hexacyanoferrate supported palladium nanoparticles (Pd-NiHCF NPs) were synthesized and studied for oxygen reduction reactions in direct methanol fuel cell. The NiHCF support was readily synthesized by a comixing of Ni(OCOCH 3 ) 2 and equimolar K 3 [Fe(CN) 6 ] solution into DI water under rigorous stirring. After the preparation of NiHCF support, Pd NPs were loaded on NiHCF via L-ascorbic acid reduction method at 80 o C. Pd-NiHCF NPs were electrochemically active for oxygen reduction reaction in 0.1 M HClO 4 solution. X-ray absorption near edge structure analysis was conducted to measure the white line intensity of Pd-NiHCF to verify the OH adsorption. As a comparison, carbon supported Pd NPs exhibited same white line intensity. This study provides a general synthetic approach to easily load Pd NPs on porous coordination polymers such as NiHCF and can provide further light to load Pd based alloy NPs on NiHCF framework.
