Inspired by hindwing structure of Troides magellanus, a new kind of anti‐counterfeiting material taking advantage of both physical and chemical structures to display multiple optical states...
The hydrodenitrogenation (HDN) of quinolone (Q) and decahydroquinoline (DHQ) over a Ni2P catalyst prepared by the reduction of a conventional phosphate precursor and a surface nickel phosphosulfide phase (Ni2P–S) obtained by the reduction of Ni2P2S6 were studied. A reaction network of the HDN of Q over Ni2P was proposed. Both the hydrogenation and C–N bond cleavage activities of Ni2P were enhanced...
