Abstract
. This material maintains high photocatalytic performance within the NIR range and demonstrates sustained stability over a 16-hour continuous reaction. This study sets the stage for fabricating stable perovskite-based photocatalysts and breaks through the spectral absorption range of halide perovskite materials, and the proposed strategy extends light absorption to activate NIR photoactivity.
