Heteroatom-doped polyaromatic hydrocarbons (or nanographenes) are promising molecular electrocatalysts for the oxygen reduction reaction (ORR). Here, we use density functional theory to investigate the first step of the ORR pathway (chemisorption) for a se ...

In the FeGP cofactor of [Fe]-hydrogenase, low-spin Fe-II is in complex with two CO ligands and a pyridinol derivative; the latter ligates the iron with a 6-acylmethyl substituent and the pyridinol nitrogen. A guanylylpyridinol derivative, 6-carboxymethyl-3 ...

The development of new catalytic methods for organic synthesis is a critical endeavour in order to obviate the economic and ecological drawbacks of stoichiometric organic synthesis. While catalysis can offer significant advantages in terms of atom-economy, ...

Electrocatalysts play an important part on the route towards environmental friendly energy sources. They support modern technologies like fuel cells to move further away from the utilization of fossil fuels and the resulting CO2 emission into our atmospher ...

Tailoring the interfacial sites between metals and metal oxides can be an essential tool in designing heterogeneous catalysts. These interfacial sites play a vital role in many renewable applications, for instance, catalytic CO2 reduction. Postsynthesis de ...

A facile approach to a corncob biorefinery, focusing on both carbohydrate valorization and lignin stabilization, was proposed to coproduce platform chemicals (glucose, xylose, arabinose, and furfural) and lignin. Different metal chloride prehydrolyses of c ...

Hydrogenolysis of C-O bonds is a highly challenging reaction with the most efficient catalysts based on bimetallic assemblies. Systematic studies to identify the optimum metal combination have not been performed and, therefore, we designed a method to scre ...

Chiral cyclopentadienyl (Cp-x) group 9 metal complexes have become versatile catalysts for a variety of efficient enantioselective C-H functionalizations. Atropchiral binaphthyl-derived Cp-x ligands having tuning options at the 3,3'-positions present a rob ...

Transition and rare earth metal vanadates are potential active phases for the selective catalytic reduction (SCR) of nitric oxide by ammonia for exhaust gas emission control. In this work, various metal vanadates mixed with SiO2-WO3-TiO2 (TWS) were compare ...

The redox chemistry of f-elements is drawing the attention of inorganic chemists due to their unusual reaction pathways. Notably low-valent f-element complexes have been shown to be able to activate small molecules such as CO2 and N2 in mild conditions. Co ...

Metal organic supramolecular chemistry on surfaces has matured to a point where its underlying growth mechanisms are well understood and structures of defined coordination environments of metal atoms can be synthesized in a controlled and reproducible proc ...

Natural colloids are defined as macromolecules and nanoparticles with sizes ranging between 1 nm and 1 µm. Colloidal pool is complex "ill-defined" mixture of humic substances, exopolymeric substances (EPS), inorganic oxides, clays, etc. Aquatic colloids ha ...

Metal-organic coordination interactions are prime candidates for the formation of self-assembled, nanometer-scale periodic networks with room-temperature structural stability. We present X-ray photoelectron spectroscopy measurements of such networks at the ...

Supported metal catalysts are important from both an industrial and a scientific point of view. They are used, amongst others, in large-scale processes such as catalytic reforming, hydrotreating, polymerization reactions and hydrogenations. Often, these ca ...
