A primary concern is how people will breathe. Oxygen tanks cannot be shuttled out to resupply the astronauts, so the air must be recycled.
Yet state-of-the-art systems are only about 50 per cent efficient at recovering used oxygen from carbon dioxide, researchers said.
NASA is funding several projects attempting to solve this problem, one of which involves Feng Jiao, assistant professor in University of Delaware 's Department of Chemical and Biomolecular Engineering. After Jiao and his colleagues published a paper in Nature Communications describing a silver electrocatalyst, a scientist at NASA 's Glenn Research centre contacted them. Jiao's team had created the silver electrocatalyst that, due to its carefully designed nanoscale structure, could convert carbon dioxide to carbon monoxide with 92 per cent efficiency - freeing oxygen in the process.
The catalyst itself is a silver coating on the surface of an electrode that increases the efficiency of the CO2-CO reaction by assisting with the transfer of electrons. It's very selective, very efficient," Jiao said. Carbon monoxide CO has many industrial applications, and the initial idea was to convert abundant CO2 to useful CO, with the oxygen as an incidental byproduct. Burke's lab was working on a technology to convert two molecules of carbon monoxide to one molecule of carbon dioxide and one molecule of carbon.
If they can combine their systems, said Jiao, "then eventually we can completely split CO2 to one molecule of carbon and one molecule of oxygen. NASA is very interested in developing this kind of technology for deep space exploration," Jiao said. The first challenge for the team is to convert the university laboratory's electrocatalysis device. The system currently processes its ingredients in batches, but for this purpose it must run continuously.
They then have to integrate their part of the work with what Burke's lab in Ohio has created. Read more on Scientist. National Aeronautics and Space Administration. University of Delaware.

Catalyst: Strategic – Space 2019
October 10, Many technical processes, including chemical production, exhaust gas purification and the chemical storage of solar energy would not be possible without catalysts. In the chemical industry, the vast majority of products produced come into contact with at least one heterogeneous catalyst. Such catalysts are solid substances on whose surfaces gaseous substances adsorb and react. The catalyst enables or accelerates their reaction to produce the product without changing itself.
Catalysts are vitally important to industry across the world. The annual value of the catalyst industry worldwide is measured in billions of dollars. In the Haber process hydrogen reacts with nitrogen to produce ammonia. Without a catalyst the process would proceed so slowly as to be economically unviable. One of the reasons for this is because of the nature of the reaction:. One route is as follows:. However breaking open the nitrogen triple bond to form N 2 H 2 is very difficult and the resulting compound is highly unstable and is likely to dissociate almost as soon as it forms.
Catalysis Letters. To check the optimal conditions for an efficient methanol production the influence of temperature and space velocity on the catalytic performance has been demonstrated. Time-on-stream measurements in the absence and the presence of benzene in the gas feed mixture were performed to investigate the possibility to use alternative carbon sources, which contain traces of aromatics.
Catalyst: Strategic — Space Catalyst Space accelerates the development of space sector capability in New Zealand by building complementary partnerships with leading international space organisations, enabling New Zealand's researchers to gain access to a wider range of experience and resources than they can domestically. The six funded projects involve a significant degree of novel research across a wide range of fields. Researchers will have the opportunity to develop critical competencies alongside world-class partners in teams with strong established track records. We received 29 proposals in total from a wide variety of organisations, showing a promising foundation for future initiatives. Catalyst: Strategic is one of the four funding streams within the Catalyst Fund. Space satellite mission design and control - The University of Auckland. Satellite mission design is a discipline unto itself — figuring out how achieve your scientific or commercial goals in space requires input from end-users, funders, scientists, engineers and mission control operatives. Endless rounds of document sharing and video conferencing is not the way to design a coherent mission. What does work, is getting everyone into the same room and not letting them out until a mission design has been finalised that will hit the mission goals.
This perspective discusses the general concepts that will guide future catalysis and related grand challenges based on the Science and Technology Roadmap on Catalysis for Europe prepared by the European Cluster on Catalysis. To address the changing scenarios in refinery and chemical production and move to a low-carbon sustainable future, the distinguishing elements of three grand challenges for catalysis are discussed here: 1 catalysis to address the evolving energy and chemical scenario, 2 catalysis for a cleaner and sustainable future, and 3 addressing catalysis complexity, the latter being organized into three sub-topics: advanced design of novel catalysts, understanding catalysts from the molecular to the material scale, and expanding catalysis concepts.

Catalysis in industry
Catalysts are substances that speed up reactions by providing an alternative pathway for the breaking and making of bonds. Key to this alternative pathway is a lower activation energy than that required for the uncatalysed reaction. Catalysts are often specific for one particular reaction and this is particularly so for enzymes which catalyse biological reactions, for example in the fermentation of carbohydrates to produce biofuels. Much fundamental and applied research is done by industrial companies and university research laboratories to find out how catalysts work and to improve their effectiveness. Further, it may be possible to reduce the amount of reactants that are wasted forming unwanted by-products.
