“…Hence, it is an urgent desire for researchers to develop many different kinds of bifunctional electrocatalysts with different performance to promote the development of H 2 fuels [30]. Transition metal oxide [31,32], transition metal sulfides [33][34][35][36][37][38][39] and selenides [40][41][42][43], transition metal phosphides [44][45][46][47][48][49], transition metal nitrides [50][51][52] become potential candidates as non-noble metal electrocatalysts for electrolysis of water. The Ni 3 S 2 /MnS-O nanosheets on Ni foam (NF/T(Ni 3 S 2 /MnS-O)) were employed as anode and cathode for overall water splitting ( Fig.…”

HIGHLIGHTS • Bifunctional electrode and electrolytic cell configuration for electrochemical water splitting are reviewed. • The different green energy systems powered water splitting are summarized and discussed. • An outlook of future research prospects for the development of green energy system powered water splitting in practical application process is proposed. ABSTRACT Hydrogen (H 2) production is a latent feasibility of renewable clean energy. The industrial H 2 production is obtained from reforming of natural gas, which consumes a large amount of nonrenewable energy and simultaneously produces greenhouse gas carbon dioxide. Electrochemical water splitting is a promising approach for the H 2 production, which is sustainable and pollution-free. Therefore, developing efficient and economic technologies for electrochemical water splitting has been an important goal for researchers around the world. The utilization of green energy systems to reduce overall energy consumption is more important for H 2 production. Harvesting and converting energy from the environment by different green energy systems for water splitting can efficiently decrease the external power consumption. A variety of green energy systems for efficient producing H 2 , such as two-electrode electrolysis of water, water splitting driven by photoelectrode devices, solar cells, thermoelectric devices, triboelectric nanogenerator, pyroelectric device or electrochemical water-gas shift device, have been developed recently. In this review, some notable progress made in the different green energy cells for water splitting is discussed in detail. We hoped this review can guide people to pay more attention to the development of green energy system to generate pollution-free H 2 energy, which will realize the whole process of H 2 production with low cost, pollution-free and energy sustainability conversion.

“…Considering these results, the reaction process driven by Rh doped CoFe-ZLDH follows the Volmer-Heyrovsky mechanism to achieve a rapidly increasing hydrogen evolution rate under the application of voltage. As shown in Figure 3c and Table S2 in the Supporting Information, Rh-doped CoFe-ZLDH outperforms many other previously reported state-of-art HER electrocatalysts, such as Rh 2 P, [41] L-Ag, [42] single atomic Co supported on phosphorized carbon nitride nanosheets (Co 1 /PCN), [43] NiMoO x -Ni(OH) 2 /NF, [44] interface catalyst consisting of atomic cobalt array covalently bound to distorted 1T MoS 2 nanosheets (SA Co-D 1T MoS 2 ), [45] Pt clusters in hollow mesoporous carbon spheres (Pt 5 /HMCS), [46] Ni-Fe nanoparticle (Ni-Fe NF), [39] oxygen vacancy enrich CoFe 2 O 4 (r-CFO), [47] CoFeP TAPs/Ni, [48] nickel-molybdenum-nitride nanoplates on carbon fiber cloth (Ni-Mo-N/CFC), [40] Ru SA -N-S-Ti 3 C 2 T x , [9] W-CoP NAs-CC, [49] MoP@NCHs-900, [50] Co 9 S 8 @C, [51] and Co 0.31 Mo 1.69 C/MXene/NC.

Exploring highly active and inexpensive bifunctional electrocatalysts for water‐splitting is considered to be one of the prerequisites for developing hydrogen energy technology. Here, an efficient simultaneous etching‐doping sedimentation equilibrium (EDSE) strategy is proposed to design and prepare hollow Rh‐doped CoFe‐layered double hydroxides for overall water splitting. The elaborate electrocatalyst with optimized composition and typical hollow structure accelerates the electrochemical reactions, which can achieve a current density of 10 mA cm−2 at an overpotential of 28 mV (600 mA cm−2 at 188 mV) for hydrogen evolution reaction (HER) and 100 mA cm−2 at 245 mV for oxygen evolution reaction (OER). The cell voltage for overall water splitting of the electrolyzer assembled by this electrocatalyst is only 1.46 V, a value far lower than that of commercial electrolyzer constructed by Pt/C and RuO2 and most reported bifunctional electrocatalysts. Furthermore, the existence of Fe vacancies introduced by Rh doping and the typical hollow structure are demonstrated to optimize the entire HER and OER processes. EDSE associates doping with template‐directed hollow structures and paves a new avenue for developing bifunctional electrocatalysts for overall water splitting. It is also believed to be practical in other catalysis fields as well.

“…According to the morphological relationship between the carbon material and CoSe 2 , it can be divided into coating (Zhou W. et al, 2016 ; Meng et al, 2017 ; Lu et al, 2019 ; Ding et al, 2020 ) and loading (Park and Kang, 2018 ). By coating with carbon materials, the agglomeration and corrosion of CoSe 2 can be largely restricted (Zhang F. et al, 2019 ; Zhang L. et al, 2019 ; Ding et al, 2020 ). Zhou W. et al ( 2016 ) prepared the core-shell structure of CoSe 2 @DC with CoSe 2 as the core and embedded CoSe 2 with defective carbon nanotubes by a carbonization-oxidation-sialylation strategies.…”

“…P vapor is often used for TMP preparation, but it usually requires very high temperature (>500°C) due to the non-reactivity of P 4 molecules (Zhang K. et al, 2017 ). While, such high temperature will cause the collapse of MOFs, thereby reducing the exposure of active sites and hindering electrons transport (Zhang L. et al, 2019 ). Hence, it is important to select an appropriate phosphorus source (Jia et al, 2017 ; Yang et al, 2017 ; Liu et al, 2019b ).…”

“…In addition to Co ion, the presence of other metals in the nodes or anchoring other metal ions into MOFs pores can obtain mixed Co-metal MOFs (CoM-MOFs). Compared with single metal Co-MOFs, CoM-MOFs exhibits better HER performance due to the increased active sites (Singh et al, 2019 ) or optimized absorption and desorption of hydrogen intermediates (Yilmaz et al, 2017 ; Li D. et al, 2018 ; Li X. et al, 2018 ; Yu et al, 2018 ; Chen W. et al, 2019 ; Feng et al, 2019 ; Zhang L. et al, 2019 ). In order to further improve the performance of the CoM-MOFs, it is important to understand the reaction mechanism of this materials.…”

Hydrogen has been considered as a promising alternative energy to replace fossil fuels. Electrochemical water splitting, as a green and renewable method for hydrogen production, has been drawing more and more attention. In order to improve hydrogen production efficiency and lower energy consumption, efficient catalysts are required to drive the hydrogen evolution reaction (HER). Cobalt (Co)-based metal-organic frameworks (MOFs) are porous materials with tunable structure, adjustable pores and large specific surface areas, which has attracted great attention in the field of electrocatalysis. In this review, we focus on the recent progress of Co-based metal-organic frameworks and their derivatives, including their compositions, morphologies, architectures and electrochemical performances. The challenges and development prospects related to Co-based metal-organic frameworks as HER electrocatalysts are also discussed, which might provide some insight in electrochemical water splitting for future development.
