A Z-scheme Bi₂O₂CO₃/Bi/NiAl-LDH (BBOC/LDH) nanosheet heterojunction was fabricated by a hydrothermal method. The BBOC/LDH composites exhibited superior performance for photocatalytic CO₂ reduction. A maximum yield of CH₄ with the value of 56.64 μmol/g_cat was achieved on 20%BBOC/LDH composite, which was 3.9-fold higher than pure LDH. The larger specific surface area, and the efficient separation of photoexcited electrons and holes attributed to the metal Bi SPR effect and Z-scheme heterojunction, enhanced the CO₂ photoreduction performance.

Z-Scheme Bi/Bi ₂ O ₂ CO ₃ /层状双氢氧化物纳米片异质结用于可见光下光催化CO ₂还原

采用水热法制备了Z型Bi ₂ O ₂ CO ₃ /Bi/NiAl-LDH（BBOC/LDH）纳米片异质结。BBOC / LDH复合材料在光催化CO ₂还原方面表现出优异的性能。在 20%BBOC/LDH 复合材料上实现了 CH _{4 的}最大产量，值为 56.64 μmol/g _cat，比纯 LDH 高 3.9 倍。由于金属Bi SPR效应和Z型异质结，较大的比表面积以及光激发电子和空穴的有效分离，增强了CO _{2 光}还原性能。
