In article number 1906361, Chunhua Lu, Jiahui Kou, Yuanjin Zhao, and co‐workers introduce an infrared‐light‐activated pyroelectric field into photocatalysis, which functions as a carrier driver during the photocatalytic reaction, considerably promoting charge separation and prolonging the carrier lifetime. The photocatalytic hydrogen evolution efficiency is remarkably improved more than 5 times. The generation of pyroelectric field and its effect on charge transfer behavior are investigated.
