Max-Planck-Institut für Kohlenforschung

Max-Planck-Institut für Kohlenforschung

The Max-Planck-Institut für Kohlenforschung at Mülheim an der Ruhr is more than one hundred years old, making it one of the Max Planck Society's oldest institutes. Time and again, the Institute has been a source of major technological impetus, including the Fischer-Tropsch synthesis for the production of fuels from coal, and Ziegler catalysts for the production of the major bulk plastics. Today, the Institute's activities are centred on research into energy- and resource-saving chemical reactions, with the focus on catalysis in all of its aspects. The aim of the researchers is to develop new, tailor-made catalysts – products that accelerate chemical reactions without themselves being changed. With the aid of catalysts, natural products and medically-active substances with a complicated structure can be efficiently synthesised; similarly, biomass can be converted to fuels and key basic chemicals.

Towards safer chemical reactions: HCN-free hydrocyanation through shuttle catalysis

2017 Willems, Suzanne; Morandi, Bill
Chemistry Material Sciences Solid State Research

The development of safer catalytic reactions is an important goal towards a greener chemical industry. Recently, we introduced a new concept in catalysis, shuttle catalysis, which has led to the discovery of a safer hydrocyanation process that does not rely on the use of highly toxic and volatile hydrogen cyanide. This new process facilitates the interconversion of synthetically relevant nitriles and alkenes and should inspire the invention of other transfer reactions that elude the need for hazardous reagents in the laboratory.

The promise of soluble gold and platinum complexes for homogeneous catalysis has been underestimated for decades due to their "noble“ character and thus their supposed chemical lethargy. It was only after the turn of the millennium that this topic has witnessed exponential growth and evolved into a highly competitive area of research. It seems likely that recent insights into the reigning catalytic cycles and the structure of the involved reactive intermediates will foster further progress. more

Chemistry

Enzymes are powerful and specific biocatalysts that are inseparably linked to life. Ways to manipulate enzymatic activity and specificity as a tool to produce new therapeutic agents are much sought after in biomedical and industrial research. The molecular understanding of the events involved in enzymatic activity is often of key importance for successful enzymology experiments. The article shows how computational simulations allowed to successfully predict, which single mutation can be applied to modify the specificity of a highly selective multi-enzyme complex.

Catalytic milling: A new entry point for lignocellulose biorefineries

2013 Meine, Niklas; Hilgert, Jakob; Kaldstrom, Mats; Rinaldi, Roberto; Schüth, Ferdi
Chemistry Material Sciences Solid State Research
Lignocellulose is an attractive feedstock for the production of fuels and chemicals. Unfortunately, the disintegration of this complex biopolymer is very difficult. Acid impregnation and mechanical treatment can be combined to result in a fully water-soluble product. The lignin is easily separated from the aqueous solution. The remaining compounds can be selectively converted to monomeric sugars or sugar alcohols using different catalytic processes. Moreover, fermentation for the production of ethanol is possible as well. These findings open up new possibilites for the use of biomass. more
The preparation of chiral, enantiomerically pure substances is a crucial endeavour of chemistry and one of high value to our society.

Gold Recycling

2012 Alcarazo, Manuel
Chemistry
The rapidly expanding field of gold catalysis and the growing number of research groups involved in this area clearly highlight its potential in synthetic organic chemistry. However, the continuous increase of the prize of gold as well as other noble metals during the last years makes the development of new strategies compulsory that allow for an efficient recovery and recycling of these expensive catalysts after their use. Here we show how ligands based on phosphenium and other phosphorus-centered cations can offer a potential solution to this problem. more

Cellulose is a renewable and highly available feedstock. This biopolymer is typically found in wood, straw, grass, and crop residues. Its use, as raw material for biofuel production, opens the possibility for sustainable biorefinery schemes that do not compete with food supply.

Catalytic processes for the sustainable utilization of renewable resources

2010 Palkovits, Regina
Chemistry Material Sciences
Diminishing fossil reservoirs and global warming make the efficient utilization of alternative feedstocks imperative. Lignocellulosic biomass is a promising feedstock, not in competition with food, and allows for CO2-neutral technologies. Its conversion via hydrogenolysis presents an interesting entry point for future biorefinery and the development of suitable catalysts is highly desirable. Alike, alternatives for commodities as terephthalic acid, important for PET production, are required. Based on sugars, furandicarboxylic acid, a sugar-based alternative to this compound, can be prepared. more
At first glance, it is surprising that iron constitutes one of the few remaining niches in the periodic table, as far as applications in homogeneous catalysis are concerned, since iron compounds are cheap, readily available, non-toxic and benign. This void is caused, to a large extent, by the lack of understanding of and control over the organometallic chemistry of this metal. Recent years, however, have seen important advances in this field, most notably in the area of cross coupling, to which the Mülheim laboratories have made substantial contributions. more

Complex Hydrides as Hydrogen Storage Materials

2007 Schüth, Ferdi; Felderhoff, Michael; Bogdanovic, Borislov
Chemistry Material Sciences
If our energy system is transformed to a hydrogen economy, the storage of hydrogen is one of the biggest challenges. All presently available solutions are unsatisfactory with respect to a number of different points. Complex hydrides, especially sodium alanate, are in an advanced development stage as chemical storage alternative. After discovery and optimization of a catalyst, the rehydrogenation times could be reduced to only a few minutes. The concept of catalytic enhancement of the rates of de- and rehydrogenation seems to be generalizable, so that there is hope for the discovery of further technically useful complex hydrides. more
