Catalysis research, explained
8 open-access catalysis studies, each with a flashcard deck and a quiz.
- Single-atom Co–N–C catalyzes nitroarene azo coupling
A self-supporting Co–N–C single-atom catalyst with a CoN4C8-1-2O2 site hydrogenatively couples nitroarenes to azo compounds.
- Evolved RebH chlorinates indoles at C5, C6 or C7
Mass-spectrometry-guided evolution of RebH produced variants that chlorinate tryptamine ortho, meta or para to the indole nitrogen without a synthetic directing group.
- Pyrazine reservoirs that lower cobalt HER overpotential
Moving a redox-active pyrazine on a cobalt polypyridine ligand cuts hydrogen-evolution overpotential by about 200 mV versus pyridine analogues in water.
- Ru dimer vs monomer splits CO from formate
Dilute, bright photolysis of Ru(bpy)(CO)2Cl2 gives CO; concentrated or dim light favours a Ru(I) dimer that makes formate.
- A MOF that merges Cu and Ru photocatalysis
CR–BPY1 places copper ions next to a Ru-substituted polyoxometalate so N-phenyl-THIQ and ketones couple under an 18 W lamp with pore size-selectivity.
- Solid Rh crystals isomerize butene without dissolving
A crystalline Rh σ-alkane complex swaps NBA for alkenes in the solid state and the porous ethene polymorph isomerizes 1-butene with high TOF.
- Magnetic Cu-on-pumice catalyst for nitro reductions
A cellulose-textured volcanic-pumice magnetite composite bearing copper nanoparticles reduces nitrobenzenes to anilines in eight minutes.
- On–off allosteric control of a bifunctional catalyst
A Pt(II) weak-link tweezer and a sulfonate regulator switch a squaramide–amine co-catalyst fully on or off in situ.
