“…X‐ray photoelectron spectroscopy (XPS) spectra of Co 2 P L /MnP‐3 showed peaks of Co δ+ and P δ– at 778.2 and 129.3–129.8 eV (Figure 2b), confirming the existence of Co 2 P NPs. [ 38–40 ] Mn 2p spectrum of Co 2 P L /MnP‐3 showed two main peaks at 641.3 and 642.9 eV. These peaks could be assigned to the Mn 2+ and Mn 3+ species in Co 2 P L /MnP‐3.…”

“…Furthermore, two regions (e 1 , e 2 ) of Figure 2e were chosen to distinguish the species. The lattice fringes with interplanar spacings of 0.220 and 0.219 nm were attributed to the Co 2 P [1 2 1] plane [ 38 ] (Figure 2e,e), and the lattice spacings of 0.296 and 0.307 nm corresponded to the [1 3 1] and [1 0 −2] planes of MnP‐3 in the selected area electron diffraction (SAED) pattern (Figure 2f–g; Figure S8, Supporting Information). Notably, the P element also appeared in the overlayer, thus the overlayer mainly contained Mn, O and a certain amount of P elements (Figure 2h; Figures S3b and S9, Supporting Information).…”

Strong metal‐support interaction (SMSI) is crucial for supported catalysts in heterogeneous catalysis. Here is the first report on strong metal phosphide‐phosphate support interaction (SMPSI). The key to SMPSI is the activation of P species on the support, which leads to simultaneous generation of metal phosphide nanoparticles (NPs) and core–shell nanostructures formed by support migration onto the NPs. The encapsulation state of metal phosphide and charge transfer are identical to those of classical SMSIs and can be optimally regulated. Furthermore, the strong interactions of Co2PL/MnP‐3 not only significantly enhance the anti‐oxidation and anti‐acid capability of non‐noble metal but also exhibit excellent catalytic activity and stability toward hydrogenating a wide range of compounds into value‐added fine chemicals with 100% selectivity, which is even better than Pd/C and Pt/C. The SMPSI construction can be generally extended to other systems such as Ni2PL/Mn3(PO4)2, Co2PL/LaPO4, and CoPL/CePO4. This study provides a new approach for the rational design of advanced non‐noble metal catalysts and introduce a novel paradigm for the strong interaction between NPs and support.

“…In the Co 2p profile (Figure d), peaks near 781.3 eV are consistent with Co in cobalt oxide, which could be ascribed to oxidation. Noticeably, the binding energies of the two peaks of CoWP/KB and CoWP-CA/KB (one-step aging) are extremely close to the binding energy of the Co atom (778.0 eV), while the two-step aging counterpart earns a binding energy of 778.6 eV, which is similar to Co δ+ in CoP. ,− …”

Tungsten phosphide (WP) is believed to be a promising electrocatalyst in the electrochemical hydrogen evolution reaction (HER) for its unique catalytic performances. Nevertheless, its further application is severely limited by the agglomeration caused by the high preparation temperature (over 600 °C). Herein, we adopt a citric acid-guided two-stage aging method to prepare Co-doped WP with small particle size and higher dispersity on the surface of seven different carbon supports. Co is successfully incorporated into the lattice of WP, causing preferable catalytic performance. The introduction of seven different carbon supports enhances electronic metal-supported interaction and proves this two-stage aging method universal. The as-derived CoWP-CA/KB (two-step aging) featured a low overpotential of 111 mV to achieve a current density of 10 mA cm–2, along with a desirable Tafel slope of 58 mV dec–1, outperforming most of the WP-based electrocatalysts. Besides, the electrode possesses excellent stability for 60 h without significant attenuation. Its remarkable performance results from its structure (delicate particle size, uniform dispersion, and large specific surface area) and its electrocatalytic properties (large electrochemically active surface area, excellent electrical conductivity, enhanced interfacial charge transfer kinetics, and high turnover frequency). This novel synthesis strategy will be pivotal for designing robust non-noble metal-based electrocatalysts with high HER activity and durability to meet the future keen demand for hydrogen.

“…The hydrogenation pathway for the HDS of DBT was highly favored by the Rh 2 P/SiO 2 catalyst, whereas the direct desulfurization pathway was favored by the Rh/SiO 2 and sulfided Rh/SiO 2 catalysts. Recently, Sheng and co‐workers [ 319 ] synthesized CoP and Co 2 P by TPR method for the HDS of DBT. On the basis of product formation in the HDS reaction of DBT, a reaction network could be proposed and the relevant mechanism of CS bond cleavage in DBT and related intermediates could be predicted as shown in Figure .…”

Transition metal phosphides (TMP) posses unique physiochemical, geometrical, and electronic properties, which can be exploited for different catalytic applications, such as photocatalysis, electrocatalysis, organic catalysis, etc. Among others, the use of TMP for organic catalysis is less explored and still facing many complex challenges, which necessitate the development of sustainable catalytic reaction protocols demonstrating high selectivity and yield of the desired molecules of high significance. In this regard, the controlled synthesis of TMP‐based catalysts and thorough investigations of underlying reaction mechanisms can provide deeper insights toward practical achievement of desired applications. This review aims at providing a comprehensive analysis on the recent advancements in the synthetic strategies for the tailored and tunable engineering of structural, geometrical, and electronic properties of TMP. In addition, their unprecedented catalytic potential toward different organic transformation reactions is succinctly summarized and critically analyzed. Finally, a rational perspective on future opportunities and challenges in the emerging field of organic catalysis is provided. On the account of the recent achievements accomplished in organic synthesis using TMP, it is highly anticipated that the use of TMP combined with advanced innovative technologies and methodologies can pave the way toward large scale realization of organic catalysis.
