In situ spectroscopic studies of metal oxide electrodes during water oxidation

John Kitchin, Associate Professor of Chemical Engineering, Carnegie Mellon University

Abstract

Electrochemical water splitting may be in integral part of future energy storage strategies by enabling energy storage in chemical bonds. One of the primary sources of inefficiency in the water splitting reaction is the oxygen evolution reaction, which has high reaction barriers that require additional applied electric potential to drive the reactions at practical rates. The most active electrode materials in acid electrolytes include ruthenium and iridium oxides, which are expensive but necessary for stability. In alkaline environments, many base metal oxides become stable, although they are still less active than Ru and Ir oxides. It has been known that small amounts of Fe can promote the electrochemical activity of nickel oxides, making it almost as active as cobalt oxide. We have investigated the mechanisms behind the promotion using in situ Raman and synchrotron spectroscopies as well as ex situ characterization techniques. Interestingly, we found the electrode changes under oxygen evolution conditions, turning from an oxide to an oxyhydroxide phase. Furthermore, the composition of the electrolyte has a significant effect on the oxygen evolution activity. We will discuss these results and their implications in finding better oxygen evolution electrocatalysts.

EBICS - Dr. Robert Langer Distinguished Lecture

Tue, 24 Apr 2012 07:03:02 GMT

Dr. Robert Langer of the MIT Department of Chemical Engineering

Engineering of Integrated Materials and Cell Based Systems

I will start by discussing how I - as a chemical engineer - initially got involved in the interface between biology and engineering, which would lead to the isolation of the first angiogenesis inhibitors and the development of controlled release systems for macromolecules. I will then cover the engineering of novel microelectronic systems. Such systems have the ability to sense levels of drugs or other substances in blood. They can also secrete drugs into the bloodstream. Next, the possibility of creating cell based tissues and organs - and the challenges associated with that - will be discussed. Finally, the development of new high-throughput, polymer-based tools that can control the differentiation and growth of stem cells and other cells will be examined.

Friday, February 4, 2011 - 3:00pm
MIT Campus - Stata Center, room 32-123 (Webcast)

Distinguished Lectures provide an opportunity for the Science and Technology Center on Emergent Behaviors of Integrated Cellular Systems (EBICS) to host internationally recognized leaders in relevant engineering, science, and education fields for the benefit of the broad academic community. The Distinguished Lectures are broadcast live to all EBICS partner institutions with the objective of educating a diverse audience in areas relevant to the work of the Center.

Hottel Lecture - Sunlight-driven hydrogen formation by membrane-supported photoelectrochemical water splitting

photoelectrochemical water splitting"

Abstract
We are developing an artificial photosynthetic system that will only utilize sunlight and water as the inputs and will produce hydrogen and oxygen as the outputs. We are taking a modular, parallel development approach in which the three distinct primary components-the photoanode, the photocathode, and the product-separating but ion-conducting membrane-are fabricated and optimized separately before assembly into a complete water-splitting system.

The design principles incorporate two separate, photosensitive semiconductor/liquid junctions that will collectively generate the 1.7-1.9 V at open circuit necessary to support both the oxidation of H2O (or OH-) and the reduction of H+ (or H2O). The photoanode and photocathode will consist of rod-like semiconductor components, with attached heterogeneous multi-electron transfer catalysts, which are needed to drive the oxidation or reduction reactions at low overpotentials. The high aspect-ratio semiconductor rod electrode architecture allows for the use of low cost, earth abundant materials without sacrificing energy conversion efficiency due to the orthogonalization of light absorption and charge-carrier collection. Additionally, the high surface-area design of the rod-based semiconductor array electrode inherently lowers the flux of charge carriers over the rod array surface relative to the projected geometric surface of the photoelectrode, thus lowering the photocurrent density at the solid/liquid junction and thereby relaxing the demands on the activity (and cost) of any electrocatalysts. A flexible composite polymer film will allow for electron and ion conduction between the photoanode and photocathode while simultaneously preventing mixing of the gaseous products. Separate polymeric materials will be used to make electrical contact between the anode and cathode, and also to provide structural support. Interspersed patches of an ion conducting polymer will maintain charge balance between the two half-cells. The modularity of the system design approach allows each piece to be independently modified, tested, and improved, as future advances in semiconductor, polymeric, and catalytic materials are made. Hence, this work will demonstrate a feasible and functional prototype and blueprint for an artificial photosynthetic system, composed of only inexpensive, earth-abundant materials, that is simultaneously efficient, durable, manufacturably scalable, and readily upgradeable.

Wed, 08 Feb 2012 15:21:29 GMT

Phase separation is suppressed as discharge rate is increased (I/I0=.03) and the critical current is approached. There is not enough time for complete phase-separation, and a quasi-solid solution forms.

The 'Artificial Leaf'

Tue, 27 Sep 2011 21:16:53 GMT

An "artificial leaf" made by Daniel Nocera and his team, using a silicon solar cell with novel catalyst materials bonded to its two sides, is shown in a container of water with light (simulating sunlight) shining on it. The light generates a flow of electricity that causes the water molecules, with the help of the catalysts, to split into oxygen and hydrogen, which bubble up from the two surfaces.

A paper solar cell circuit is shown powering an LCD clock when illuminated. The entire integrated paper photovoltaic is then fed through a roll-to-roll office laser-jet printer. The resulting ink spells MIT on the device side of the paper array, which then continues to power the LCD clock. The clock circuitry is shown at the end of the video, which is powered by the photovoltaic alone and regulates a constant voltage to the display for variations in light intensity. The paper photovoltaic array is illuminated from below with simulated solar illumination.
