where X is selected from nitrogen, or phosphorus; Y is selected from halogens; A and B are independently selected from materials having formulae (a) to (d). Compared with catalysts with a non-spirocyclic structure or Lewis acid metal catalysts, the catalyst including the spirocyclic compound having the structural shown in formula 1 has the advantages of better catalytic effect, more stable performance and longer service life when catalyzing the reaction of the epoxy compounds and carbon dioxide. The present catalyst has both high efficiency and safety, and thus has broad application prospects.-

摘要: The invention relates to a method for activating a photocatalytically active, for example titanium-dioxide-containing, outer layer (13; 23) deposited on a composite, by means of at least one element (14; 24) generating a radiation, for example for generating ultraviolet radiation. The following method steps are comprised here: •a) forming the at least one radiation-generating first element (14; 24) within the composite; •b) forming at least one sensor (16; 26) within the composite; •c) recording an actual value of a physical variable characterizing luminous radiation by means of the at least one sensor (16; 26), wherein the luminous radiation is emitted by a light-generating second element (15; 25); •d) comparing the recorded actual value with a first threshold value within an evaluation device and switching on the at least one radiation-generating first element (14; 24) if the actual value is below or above the first threshold value.
