<i>In situ</i> modification of bismuth oxyhalide photocatalysts with natural chlorophyll for enhanced photocatalytic performance.

ABSTRACT: Bismuth oxyhalides (BiOX) exhibit limited sunlight absorption and utilization, presenting a challenge for their effectiveness in photocatalytic applications. This study draws inspiration from the sensitization effects of natural chlorophyll on semiconductor photocatalysts, achieving in situ synthesis of chlorophyll-sensitized BiOX photocatalysts through a precipitation method. The photocatalytic activity of these materials was evaluated under blue light irradiation (410-420 nm LED) using Rhodamine B (RhB) as a model pollutant. Experimental results reveal that chlorophyll derived from Chlorella effectively sensitized BiOX samples, changed them specific surface area, and surface potential, thereby enhancing RhB degradation efficiency. Among the as-prepared BiOX materials, BiOBr
