Abstract
A novel photocatalyst (BOC(101)-OVs) of bismuth oxychloride with largely exposed (101) crystal plane and rich oxygen vacancies was synthesized, exhibiting a high NH3 yield after photocatalytic N2 reduction under solar light irradiation. The enhanced photocatalytic activity is attributed to overcome confinement by the photo-Dember effect, leading to >95% of photogenerated electrons changing their transfer path from (001) to (101) crystal plane. As a result, a new nitrogen reduction pathway with combined alternating hydrogenation and terminal hydrogenation is found, as reported by Wen Liu et al. (e202503097).
