Subnanometric Platinum–Germanium Clusters for Efficient Propane Dehydrogenation Catalysis

open access: yesSmall, EarlyView.
Pt─Ge alloy clusters are regioselectively encapsulated within the sinusoidal channels of pure silica MFI zeolite (PtGe@MFI). The developed Pt─Ge alloy clusters exhibit exceptional performance with 36‐fold higher activity than the most stable catalyst ever reported and twice its stability, and with comparable activity to and 21‐fold higher stability ...

Fluorinated CuO/ZnO/MgO Catalyst Systems for the Direct CO2 Hydrogenation to DME

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
Direct CO2 conversion to dimethyl ether (DME) is a promising CO2 valorization route requiring a bifunctional catalyst for CO2 hydrogenation and MeOH dehydration. The established CuO/ZnO/ZrO2 (CZZ) system shows good activity but high material costs. Hence, a novel fluorinated CuO/ZnO/MgO (CZMg‐F) system was tested in the direct DME synthesis, offering a

Passive environmental DNA sampling: A review of current practices, limitations and future directions for biodiversity monitoring

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Passive environmental DNA (eDNA) sampling is rapidly emerging as a powerful alternative to active sampling methods (e.g. direct water sampling), with a rapidly growing diversity of tested approaches but little methodological convergence.
