Photocatalytic water splitting is an effective and attractive technology to convert solar energy into clean hydrogen energy. Since the pioneering work reported on TiO 2 electrode in 1972, 1 researchers have studied a series of catalysts ranging from metal oxides to other materials, such as metal sulfides, 2,3 non-metal semiconductors (e.g., C 3 N 4 and graphene), 4,5 and complex catalysts. [6][7][8][9] As one of the important metal sulfides, CdS have attracted widely attention due to its relatively simple chemical

“…The vibration modes of the Cu 3 P [34] were also apparently detected from the NF-CNP (Figure S5c, Supporting Information) and NF-CNNOP (Figure S5b, Supporting Information) samples. However, the Raman peaks of Ni 2 P cannot be detected, [35,36] which were perpetual to Ni 2 P. Noticeably, the Raman vibration of NiO cannot be observed in the Raman spectrum of NF-CNNOP sample but its intensity significantly decreases, suggesting the partial phosphidation of the ternary hybrid sample. [37,38] The cross-sectional morphological studies on the pristine NF and as-prepared samples are presented in Figure 1c-f to have detailed understanding of the surface morphological reaction.…”

The ever‐growing portable electronics and electric vehicle draws the attention of scaling up of energy storage systems with high areal‐capacity. The concept of thick electrode designs has been used to improve the active mass loading toward achieving high overall energy density. However, the poor rate capabilities of electrode material owing to increasing electrode thickness significantly affect the rapid transportation of ionic and electron diffusion kinetics. Herein, a new concept named “sub‐thick electrodes” is successfully introduced to mitigate the Li‐ion storage performance of electrodes. This is achieved by using commercial nickel foam (NF) to develop a monolithic 3D with rich in situ heterogeneous interfaces anode (Cu3P‐Ni2P‐NiO, denoted NF‐CNNOP) to reinforce the adhesive force of the active materials on NF as well as contribute additional capacity to the electrode. The as‐prepared NF‐CNNOP electrode displays high reversible and rate areal capacities of 6.81 and 1.50 mAh cm−2 at 0.40 and 6.0 mA cm−2, respectively. The enhanced Li‐ion storage capability is attributed to the in situ interfacial engineering within the NiO, Ni2P, and Cu3P and the 3D consecutive electron conductive network. In addition, cyclic voltammetry, charge–discharge curves, and symmetric cell electrochemical impedance spectroscopy consistently reveal improved pseudocapacitance with enhanced transports kinetics in this sub‐thick electrodes.

[58] TMPs, including Ni 2 P, WP, FeP, Co 2 P, and others, are often employed in combination with metal sulfides, [35,59] metal oxides, [39,60] g-C 3 N 4 , [61,62] and other photocatalytic materials to achieve better photocatalytic effect.…”

Photocatalytic hydrogen evolution can effectively alleviate the troublesome global energy crisis by converting solar energy into the chemical energy of hydrogen. In order to realize efficient hydrogen generation, a variety of semiconductor materials have been extensively investigated, including TiO2, CdS, g‐C3N4, metal‐organic frameworks (MOFs), and others. In recent years, to achieve higher photocatalytic performance and reach the level of large‐scale industrial applications, photocatalysts decorated with transition metal phosphides (TMPs) have shone brightly because of their low cost, stable physical and chemical properties, and substitution for precious metals of TMPs. This Review highlights the preparation methods and properties associated with photocatalysis of TMPs. Moreover, the H2 generation efficiency of photocatalysts loaded with TMPs and the roles of TMPs in catalytic systems are also studied systematically. Apart from being co‐catalysts, several TMPs can also serve as host catalysts to boost the activity of photocatalytic composites. Finally, the development prospects and challenges of TMPs are put forward, which is valuable for future researchers to expand the application of TMPs in photocatalytic directions and to develop more active photocatalytic systems.
