Liang, H. Q., Zhao, S., Hu, X. M., Ceccato, M., Skrydstrup, T. & Daasbjerg, K. https://doi.org/10.1021/acscatal.0c03766 Cu is in the spotlight as it represents the only metal capable of catalyzing CO2 reduction to multicarbon products. However, its catalytic performance is determined collectively by a number of parameters including its composition and structure, electrolyte, and cell configuration. It…
Li, S., Ceccato, M., Lu, X., Frank, S., Lock, N., Roldan, A., Hu, X. M., Skrydstrup, T. & Daasbjerg, K. 10.1039/d0ta08433f The design of selective and efficient catalysts for electrochemical CO2 reduction is highly desirable yet still challenging, in particular, if the aim is to make them binder-free and self-standing. Here, we report a new and straightforward…
Heide-Jørgensen, S., Budzik, M. K., Buhl, K. B., Hinge, M., Pedersen, S. U., Daasbjerg, K. & Kongsfelt, M. https://doi.org/10.1016/j.engfracmech.2020.107413 Peeling and cleavage are common load cases for studying and evaluating adhesion between materials. The former is suitable for testing adhesion of thin or highly flexible materials for which the bending energy is negligible while the latter…

D., Daasbjerg, K. & Skrydstrup, T. https://doi.org/10.1038/s41929-020-00510-z Industrially, aldehydes are produced annually on a multimillion-tonne scale via the hydroformylation of olefins with syngas (CO/H2 mixture). Nonetheless, this transformation has not found frequent use in the laboratory. Here we report on a simple…

One approach to mitigate fouling is to employ surface coatings. In this study, we evaluated…
Xin-Ming Hu, Kim Daasbjerg 10.1038/d41586-019-03563-8 A molecular catalyst dispersed on carbon nanotubes has been found to catalyse the electrochemical conversion of carbon dioxide to methanol — a liquid fuel and industrially useful bulk chemical.
