The processes of urban obsolescence will be increasingly common in an urbanized world, especially in some territories with a long urban history such as Europe. To promote urban regeneration, the key idea is that architecture renewal in relationship to public spapce can become an urban catalyst, under certain conditions of design. The desired urban stimulus may be produced: the improvement of the urban ecosystem and the environment. The future involves an architecture that acts together the public space that can produce reactions that diminish the environmental impact and promote urban revitalization.

Catalyst @ Penn GSE
Acrolein can be obtained from glycerine by a dehydration reaction. Catalytic processes in gas phase have been developed to obtain acrolein from a renewable feedstock using heterogeneous catalysts. The main process variables are the reaction temperature, the concentration of glycerol in water, and the space velocity in fixed-bed reactors. A thermodynamic study of the equilibrium has been made to estimate the conversion to equilibrium as a function of temperature.
Designed to help produce oxygen on board spacecraft, a life-support system made by Airbus for the European Space Agency ESA revolves around a Sabatier reactor with an Evonik catalyst. German astronaut and ISS Commander Alexander Gerst has now installed the module, which will begin operation in early The system is to undergo testing through the end of the year to assess its serviceability. The ACLS advanced closed-loop system is a life-support system that produces oxygen, water, and, as a by-product, methane. The heart of the system is a fixed bed catalyst from Evonik installed in what is known as a Sabatier reactor. Before air is circulated back into the space station, carbon dioxide is first separated out. Inside the Sabatier reactor, this CO 2 passes over the catalyst, where it reacts with hydrogen H 2 that has been fed into the system to form water H 2 O and methane CH 4. The reaction proceeds in two steps, with temperatures reaching some degrees Celsius during the first step and degrees during the second. But where does the hydrogen come from?
Catalytic Dehydration of Glycerine to Acrolein
November 11, Seawater is one of the most abundant resources on earth, offering promise both as a source of hydrogen—desirable as a source of clean energy—and of drinking water in arid climates. But even as water-splitting technologies capable of producing hydrogen from freshwater have become more effective, seawater has remained a challenge.
Northwestern University chemists have used visible light and extremely tiny nanoparticles to quickly and simply make molecules that are of the same class as many lead compounds for drug development. Driven by light, the nanoparticle catalysts perform chemical reactions with very specific chemical products -- molecules that don't just have the right chemical formulas but also have specific arrangements of their atoms in space. And the catalyst can be reused for additional chemical reactions. The semiconductor nanoparticles are known as quantum dots -- so small that they are only a few nanometers across. But the small size is power, providing the material with attractive optical and electronic properties not possible at greater length scales. Weiss, who led the research. We can take advantage of this, along with the templating power of the nanoparticle surface. This work, published recently by the journal Nature Chemistry , is the first use of a nanoparticle's surface as a template for a light-driven reaction called a cycloaddition, a simple mechanism for making very complicated, potentially bioactive compounds.
New catalyst efficiently produces hydrogen from seawater

After it became apparent that NO decomposition catalysts had too many shortcomings to produce a robust, commercial catalyst system  , research turned towards selective reduction of NOx by compounds of combustion gases. It was discovered that several catalysts promoted selective catalytic reduction of NOx by hydrocarbons or other exhaust gas components, including carbon monoxide, or alcohols . NOx reduction by HC was found to be less susceptible to sulfur poisoning than NO decomposition and higher conversion efficiencies were demonstrated.
Catalyst supplies oxygen to astronauts on board the ISS
Scientists from Trinity College Dublin have teamed up to begin solving one of the big problems facing clean energy hydrogen production. They've been studying ways to better catalyze splitting water into energy-ready hydrogen. But that stability means trying to split water into its component parts is really difficult. Think about how easy it is to accidentally dye a load of whites by dropping in one red sock, and how impossible it is to take the pink color back out of those clothes. They focused on just homogeneous catalysts, meaning substances that are also liquids if the goal is to split liquid water, but choose to bring in qualities of good heterogeneous catalysts as well. The science is complicated, but the bottom line is that the team listed all the possible ingredients and used powerful computers to smash countless combinations together. By considering a wider range of values for each component and testing formulas that include all those different values, the researchers found wildly promising candidate formulas that could reduce the previous obstacles to almost zero. Computer simulations can speed up both test cases in simulations and the calculation of what those test cases should be to begin with. Why is a plentiful hydrogen source so important? Hydrogen is a viable alternative energy source that can generate electric power for cars and other applications, and it has advantages over or complementary qualities to other renewable fuels.
Optionally, ruthenium on alumina aluminium oxide makes a more efficient catalyst. It is described by the following exothermic reaction. There is disagreement on whether the CO 2 methanation occurs by first associatively adsorbing an adatom hydrogen and forming oxygen intermediates before hydrogenation or dissociating and forming a carbonyl before being hydrogenated. CO methanation is believed to occur through a dissociative mechanism where the carbon oxygen bond is broken before hydrogenation with an associative mechanism only being observed at high H 2 concentrations.
Water Is Really Hard and Expensive to Split. These Guys Might Have a Solution.
Methane dry reforming presents a unique opportunity to simultaneously consume both methane and carbon dioxide and generate from them clean-burning synthetic fuels for mobile energy applications. The industrialization of CH 4 dry reforming has been impeded mainly due to problems relating to the catalyst—support interface including sintering and carbon accumulation.
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.
