Pd catalysts anchored on manganese oxide octahedral molecular sieves (OMS-2) were synthesized by photo-deposition method, and then used for one-step oxidative carbonylation of phenol to synthesize diphenyl carbonate (DPC). The results showed that the catalytic activity of Pd/OMS-2 catalyst prepared by photo-deposition was apparently better than those prepared by the traditional precipitation and impregnation method, the distribution of Pd particles was more uniform with the average size of 1.3 nm. This may result from the strong interaction between the carriers and the active Pd species. Irradiated for 5 h at pH 5.0, with the Pd loading of 2.5 wt%, the highest DPC yield of 18.1% was achieved.

通过光沉积法合成了锚固在氧化锰八面体分子筛（OMS-2）上的钯催化剂，并将其用于苯酚的一步氧化羰基化反应，合成碳酸二苯酯（DPC）。结果表明，光沉积法制备的Pd / OMS-2催化剂的催化活性明显优于传统的沉淀和浸渍法制备的Pd / OMS-2催化剂，其Pd颗粒的分布更均匀，平均粒径为1.3 nm。这可能是由于载流子与活性Pd物质之间的强相互作用所致。在5.0的pH值下辐照5 h，Pd的负载量为2.5 wt％，DPC的最高收率为18.1％。
