Wood waste from sports equipment is regarded as potentially valuable resource, providing attractive material platform to develop efficient photocatalysts. In this study, new bismuth molybdate photocatalyst, P-Bi₂MoO₆ with wood powder morphology, was prepared using waste table tennis bat poplar baseplates via a facile one-step synthesis using wood bionic processing technique combined with solvothermal method. Photocatalytic activity of samples was evaluated by the decomposition of tetracycline hydrochloride (TC) under visible-light irradiation. Results show that compared with conventional bismuth molybdate, synthesized P-Bi₂MoO₆ exhibited higher photodegradation efficiency. This can be mainly attributed to the decrease in crystallite size, enrichment in surface-active oxygen species, improved light absorption, efficient carrier separation, and strengthened charge transfer. Electron spin resonance and quenching experiments confirm that OH• and •O₂⁻ radicals are the major reactive species during the photocatalytic reaction. This study provides a new synthetic strategy for photocatalysts with different shapes for the purification of water environment.

运动器材产生的木材废料被视为具有潜在价值的资源，为开发高效光催化剂提供了有吸引力的材料平台。在这项研究中，采用木材仿生加工技术结合溶剂热法，通过简单的一步合成，利用废弃乒乓球拍杨木基板制备了具有木粉形态的新型钼酸铋光催化剂 P-Bi ₂ MoO ₆。通过在可见光照射下四环素盐酸盐 (TC) 的分解来评估样品的光催化活性。结果表明，与常规钼酸铋相比，合成的P-Bi ₂ MoO ₆表现出更高的光降解效率。这主要归因于微晶尺寸的减小、表面活性氧物质的富集、光吸收的改善、载流子的有效分离和电荷转移的加强。电子自旋共振和猝灭实验证实，OH• 和•O ₂ ^-自由基是光催化反应过程中的主要反应物质。该研究为不同形状的光催化剂用于水环境净化提供了一种新的合成策略。
