Abstract
Abstract Energy shortages and greenhouse effects are two unavoidable problems that need to be solved. Photocatalytically converting CO 2 into a series of valuable chemicals is considered to be an effective means of solving the above dilemmas. Among these photocatalysts, the utilization of black phosphorus for CO 2 photocatalytic reduction deserves a lightspot not only for its excellent catalytic activity through different reaction routes, but also on account of the great preponderance of this relatively cheap catalyst. Herein, this review offers a summary of the recent advances in synthesis, structure, properties, and application for CO 2 photocatalytic reduction. In detail, the review starts from the basic principle of CO 2 photocatalytic reduction. In the following section, the synthesis, structure, and properties, as well as CO 2 photocatalytic reduction process of black phosphorus‐based photocatalyst are discussed. In addition, some possible influencing factors and reaction mechanism are also summarized. Finally, a summary and the possible future perspectives of black phosphorus‐based photocatalyst for CO 2 reduction are established.
