The leaching and non-recoverability of mental ions have always limited the practical application of Fenton-like processes. For the first time, we synthesized molybdenum phosphide (MoP) with dual active sites for the degradation of diclofenac (DCF) in the Fenton-like process. The DCF degradation rate constant (k) of MoP + H₂O₂ process was calculated to be 0.13 min^-1 within 40 min, indicating a highly efficient catalytic ability of MoP. In addition, this catalyst exhibits a stable structure and good activity, which could apply in a broad pH range, different ions solution and real wastewater condition. Accordingly, this efficient catalytic capability may be attributed to the presence of the metal sites Mo^δ+ and the electron-rich sites P^δ− in MoP, which could induce the generation of hydroxyl radical (^•OH) and superoxide radical (^•O₂⁻) through electron transfer, resulting in the effective removal of DCF. This study provides an idea for the optimization of Fenton-like technologies and environmental remediation.

金属离子的浸出性和不可回收性一直限制了类芬顿工艺的实际应用。我们首次合成了具有双活性位点的磷化钼 (MoP)，用于在类芬顿过程中降解双氯芬酸 (DCF)。MoP+H ₂ O ₂过程的DCF降解速率常数(k)经计算在40 min内为0.13 min ^-1，表明MoP具有高效的催化能力。此外，该催化剂结构稳定，活性良好，适用于较宽的pH范围、不同的离子溶液和实际废水条件。因此，这种有效的催化能力可能归因于金属位点 Mo ^{δ+的存在。}MoP中的富电子位点P ^δ-可以通过电子转移诱导羟基自由基( ^• OH)和超氧自由基( ^• O ₂ ^- )的产生，从而有效去除DCF。本研究为优化类芬顿技术和环境修复提供了思路。
