The diatomic molecule PH is very reactive, and it serves as the parent compound for phosphinidenes featuring a monovalent phosphorus atom. Herein, we report the characterization and reactivity of a rare hydrogen‐bonded complex of PH. Specifically, the molecular complex between PH and HCl has been generated by photolysis of chlorophosphine (H2PCl) at 254 nm in a solid Ar‐matrix at 10 K. The IR spectrum...
Phytochemical investigation on the anti‐inflammatory fraction extracted from the whole plant of Euphorbia helioscopia L. led to the isolation of three new ent‐atisane diterpenoids (1–3) and five known analogues (4–8). The structures and absolute configurations of the new compounds were elucidated by comprehensive analysis of the NMR, MS, IR, ECD, and X‐ray crystallography. It is worth mentioning that...
Palladium (Pd)‐modified metal oxide semiconductors (MOSs) gas sensors often exhibit unexpected hydrogen (H2) sensing activity through a spillover effect. However, sluggish kinetics over a limited Pd‐MOS surface seriously restrict the sensing process. Here, a hollow Pd‐NiO/SnO2 buffered nanocavity is engineered to kinetically drive the H2 spillover over dual yolk‐shell surface for the ultrasensitive...
The unsaturated coordination and abundant active sites endow amorphous metals with tremendous potential in improving metal oxide semiconductors’ gas‐sensing properties. However, the amorphous materials maintain the metastable status and easily transfer into the lower‐active crystals during the gas‐sensing process at high working temperatures, significantly limiting their further applications. Here,...
