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.

Overall water splitting is a hot topic in the development of green energy, but it cannot be generalized on a large scale due to the lack of low-cost and highly efficient overall water-splitting catalysts. As a result, currently, the exploitation of stable and nonprecious metal catalysts with elevated performance has become a research focus in overall water splitting. Here, we introduce a multicomponent material (Ni/MoC/Ti3C2T x @C) by a strategy of the combination of electrostatic assembly and elevated-temperature calcination to employ it as an electrocatalyst for water splitting and urea oxidation. The Ni/MoC/Ti3C2T x @C electrocatalyst presents a superior hydrogen evolution reaction and oxygen evolution reaction ability with an overpotential of 128 and 338 mV at 10 mA cm–2 in 1.0 M KOH, respectively, along with long-term stability over 24 h. The Ni/MoC/Ti3C2T x @C catalyst has a turnover frequency of 1.64 s–1 at 100 mV. Improved catalytic behavior of Ni/MoC/Ti3C2T x @C is principally due to the synergistic effect of Ni and MoC nanoparticles, the introduction of the conductive Ti3C2T x MXene matrix with a layered porous structure, and the protection of the carbon layer. In addition, when Ni/MoC/Ti3C2T x @C electrodes are used to electrolyze water with urea assistance, a voltage of 1.56 V is required for both electrodes to reach 10 mA cm–2, which is 80 mV lower than that required for conventional water electrolysis. Our work provides a strategy for the exploitation of elevated-performance MXene-based electrocatalysts for overall water splitting as well as future advancement of green energy.
