“…In addition, carbon can accelerate the electron conductivity of catalysts, thereby enhancing the catalytic performance in different reaction [22–24] . For example, our group previously reported that the modification of MoP with absorbent cotton derived carbon material confirmed that the appropriate carbon matrix was conducive to increasing the specific surface area of MoP@C catalyst to improve the hydrogenation activity [25] . However, the thermal stability of MoP modified by the single carbon material is poor, while oxygen element has recently been reported to occupy an important position in the catalytic process of HDC, often playing a role in improving the stability of MoP cycle and active sites [26–28] .…”

The harms caused by organic chlorides to the human body and the environment make the problem of how to degrade organic chlorides particularly urgent. Phosphides have gradually attracted attention in HDC due to their high catalytic performance. In view of the important role of O in catalytic process, the preparation of C, O co‐doped MoP was achieved by the synergistic modification of EDTA and glucose. Compared with unmodified MoP, the doping of carbon and oxygen in MoP−C−O ensure that more active sites are exposed on the surface. At the same time, the high dispersion of MoP on the carbon matrix increases the specific surface area of MoP−C−O, which is more conducive to the adsorption of reactants on the surface, thereby effectively improving the catalytic activity of the modified MoP−C−O. In the case of changing the molar ratio of MoP and surface modifier, the best activity of MoP−C−O (50 %) reaches 57.80 %, which is 2.3 times higher than that of MoP catalyst.

Strong metal‐support interaction (SMSI) between transition metal nanoparticles and carbon matrix offers significant structure advantages due to the ability to modulate the electronic structure of metal nanoparticles, increase the density of active sites, and improve the conductivity of catalysts. Here, ultrafine nanoparticles of metallic molybdenum compounds (MoP, Mo2C, and MoS2) strongly coupled with mesoporous carbon CMK‐5 are synthesized. The confinement growth of nanoparticles in the pores of CMK‐5 produces encapsulated nanoparticles, affording facilitated electron transfer, and enhancing the HER activity induced by the SMSI effect. The hierarchical nanostructure and strong electronic interactions between the carbon substrate and molybdenum‐based nanoparticles allow efficient mass/electron transport between the carbon substrate and molybdenum‐based nanoparticles, improving the catalytic hydrogen evolution reaction (HER) activity. The effective electron exchange between the Mo species and the CMK‐5 support is studied by X‐ray photoelectron spectroscopy (XPS) measurement, confirming the presence of the SMSI effect. The resulting MoP/CMK‐5 catalyst exhibits outstanding HER performance in alkaline (65 mV@10 mA cm−2), acidic (123 mV@10 mA cm−2), and simulated seawater electrolytes (103 mV@10 mA cm−2), making it one of the most promising catalysts reported for HER. This work provides guidance on designing high‐performance electrocatalysts with SMSI for the enhancement of the electrochemical reaction.
