Developing sustainable and renewable energy sources along with efficient energy storage and conversion technologies is vital to address environmental and energy challenges. Electrochemical water splitting coupling with gridscale renewable energy harvesting technologies is becoming one of the most promising approaches. Besides, hydrogen with the highest mass-energy density of any fuel is regarded as the ultimate clean energy carrier. The realization of practical water splitting depends heavily on the development of low-cost, highly active, and durable catalysts for hydrogen evolution reactions (HERs) and oxygen evolution reactions (OERs). Recently, heterostructured catalysts, which are generally composed of electrochemical active materials and various functional additives, have demonstrated extraordinary electrocatalytic performance toward HER and OER, and particularly a number of precious-metalfree heterostructures delivered comparable activity with precious-metal-based catalysts. Herein, an overview is presented of recent research progress on heterostructured HER catalysts. It starts with summarizing the fundamentals of HER and approaches for evaluating HER activity. Then, the design and synthesis of heterostructures, electrochemical performance, and the related mechanisms for performance enhancement are discussed. Finally, the future opportunities and challenges are highlighted for the development of heterostructured HER catalysts from the points of view of both fundamental understandings and practical applications.

“…This is because recently it was reported that the amount of Pt deposited onto the catalyst surface after multiple circular scanning improved the catalytic performance. 1 A graphite electrode was used as the counter electrode in this study. All the potentials measured were calibrated with the reversible hydrogen electrode (RHE) using the following equation: value (R) of the 1M KOH solution was measured to be 6.9 Ω at room temperature.…”

“…However, it is highly challenging to develop efficient and low-cost catalysts to meet the stringent requirements on high current density (or high power density) for industrial water electrolysis applications. 1 There is a significant progress in the past a few years for developing lowcost catalysts from earth-abundant and non-noble-metal materials for hydrogen evolution reaction (HER) (e.g., boride, phosphides, chalcogenides, and titanate) [2][3][4][5] and for oxygen evolution reaction (OER) (e.g., nitrides, oxides, hydroxides, and oxyfluoride). [6][7][8][9] Transition metal sulfides, selenides, nitrides, and phosphides have been applied as active HER catalysts.…”

converting electrical energy into chemical energy. However, both reactions require large thermodynamic overpotential to overcome the kinetic barriers. [3] The cathodic reaction of HER has received extensive attentions for hydrogen production. To improve the efficiency of electrical energy to hydrogen production, the cathodic overpotentials have to be reduced, especially at high current densities for practical application. This can be achieved via catalysts, which include transition metals and their sulfides, nitrides, phosphides, selenides, and carbides. [4] Direct solar-driven water splitting is a more sustainable and renewable strategy compared to water electrolysis. As a highly desirable approach to solve the energy crisis, it collects and stores solar energy in chemical bonds. [5] In the solar-driven water splitting reaction, a semiconductor is required to absorb radiant energies, generate electron-hole pairs, and finally drive the decomposition of water. [5] Therefore, quantum efficiency of this process is determined by the semiconductors. P-type semiconductors, for example, p-InP and Cu 2 O, with high position of conduction band, can reduce protons into hydrogen as a photocathode. However, solar to hydrogen (STH) efficiency is largely dependent on the surface reaction kinetics to some extent. [6] Solar water splitting has attracted intensive attention of researchers since the first report in 1972. [7] Its practical implementation encounters many challenges, one of which is to develop highly active sites on the bare semiconductor surface to lower HER barrier. [8] One approach to introduce catalytic active center is to coat isolated metallic nanoparticles as catalysts on the surface. [9] For instance, p-InP coated with Rh particles could yield 13.3% conversion efficiency to hydrogen. [10] The improvement is ascribed to the change of Schottky barrier height of the material system through addition of metal particles. [11] With higher density of majority carriers than the semiconductors, the metals on the surface enable facile transport of minority carriers and facilitate reduction reaction. [5] Another effective approach to overcome the kinetic limitation of solar-assisted water splitting is to provide an extra bias which helps the photogenerated electron-hole pairs separate and migrate to the electrode surface. [12] Besides, the additional bias can lead bending of the semiconductor's band and hence compensate the insufficient electronic energy and overcome the
