“…While, for Co 2p spectra, the Co 2+ 2p 3/2 position of Pd@FeNi-CoO composites (780.62 eV) shifts to a low energy region compared with Pd/FeNi-CoO composites (780.51 eV) and FeNi-CoO nanosheets (780.51 eV) (Figure d). The binding energy of each element has changed, demonstrating that different elements interact with each other, resulting in changes in electronic structure. , Furthermore, the d-band center is used to evaluate the effect of intermediate binding strength on the catalytic performance of different catalysts (Figure e). The rightward shift of the d-band center reduces the binding state and increases the antibinding state, enhancing the catalyst absorbent interaction on the Pd@FeNi-CoO composites .…”

Electrochemical nitrate (NO 3 − ) production of ammonia (NH 3 ) is not only a green and efficient NH 3 production strategy but also can solve the environmental problem of NO 3 − excess at the same time, however, there is still a lack of efficient and sensitive electrocatalysts for electrocatalytic NO 3 − reduction reaction (NO 3 RR). Herein, for the first time, Pd nanoparticles on Fe-and Ni-doped CoO nanosheets (Pd@FeNi-CoO) composites with enhanced metal−support interfacial interaction were designed as efficient electrocatalysts for NO 3 RR. Pd@FeNi-CoO composites exhibit a high NH 3 yield rate of 20.26 mg h −1 mg −1 cat. at −0.8 V versus reversible hydrogen electrode (RHE), outperforming the Pd/FeNi-CoO composites (6.23 mg h −1 mg −1 cat. ) and FeNi-CoO nanosheets (4.83 mg h −1 mg −1 cat. ).

energy system is among the most promising solutions to solve the above issues. Substituting the current energy carrier with a sustainable fuel is one of the crucial points in the system. Hydrogen as a green and high energy density carrier, primarily derived from water, can satisfy the requirement of sustainable development and facilitate environmental protection and energy conservation. Nowadays, hydrogen is mainly produced from numerous nonrenewable energy such as fossil fuels and biomass for practical applications. [1][2][3] Water electrolysis is a hopeful strategy for efficient and sustainable hydrogen production, but not cost-effective due to the need for large electricity consumption. [4,5] It remains challenging to achieve highly effective hydrogen production with lowcost and renewable energy.Sunlight is an endlessly renewable energy source, which can substitute fossil fuels. In this regard, coupling of sunlight and water electrolysis is desperately needed. The photovoltaic module coupled with water electrolyzers (PV-EC) to achieve the direct conversion of solar energy into hydrogen fuel is a good choice for sustainable energy system. The solar-driven water electrolysis can be achieved through the electrical power generated by a photovoltaic system for driving an external water electrolyzer. [6][7][8] The solar cells do not need to immerse into the electrolyte and not be vulnerable to corrosion in this configuration. However, the high cost of solar photovoltaic devices limits its practical applications. Integrated photoelectrochemical (PEC) devices comprising a photovoltaic device and a water electrolyzer in a single device have aroused much attention. [9][10][11] It allows the direct coupling of light absorbers and catalysts, which could reduce the cost and mechanical limitations. One of the most prominent works is the "artificial leaf", which comprises a triple junction and amorphous silicon photovoltaic interfaced to hydrogen-and oxygen-evolving catalyst for achieving an efficiency of 4.7%. [12] Considering the fluctuating output power and intrinsically intermittent nature of solar energy, a rechargeable energy storage device could be introduced to serve as a reservoir to offer a stable electrical output and accommodate solar energy. The PV-ES-EC system can thus be achieved through the fabrication of an efficient energy storage device to couple the photovoltaic device and water electrolyzer.Notably, the above solar-driven water electrolysis systems require highly conductive and stable separators, highly Solar-driven water electrolysis has been considered to be a promising route to produce green hydrogen, because the conventional water electrolysis system is not completely renewable as it requires power from nonrenewable fossil fuel sources. This review emphasizes the strategies for solar-driven water electrolysis, including the construction of photovoltaic (PV)-water electrolyzer systems, PV-rechargeable energy storage devicewater electrolyzer systems with solar energy as the sole input energy, and photo...

As one of the most promising approaches to producing high purity hydrogen (H2), electrochemical water splitting powered by the renewable energy sources such as solar, wind, and hydroelectric power has attracted considerable interest over the past decade. However, the water electrolysis process is seriously hampered by the sluggish electrode reaction kinetics, especially the four‐electron oxygen evolution reaction (OER) at the anode side, which induces a high reaction overpotential. At present, the emerging hybrid electrochemical water splitting strategy has been proposed by integrating thermodynamically favorable electro‐oxidation reactions with hydrogen evolution reaction (HER) at the cathode, providing a new opportunity for energy‐efficient H2 production. To achieve highly efficient and cost‐effective hybrid water splitting (HWS) towards large‐scale practical H2 production, much work has been continuously done to exploit the alternative anodic oxidation reactions and cutting‐edge electrocatalysts. This review will focus on recent developments on electrochemical H2 production coupled with alternative oxidation reactions, including the choice of anodic substrates, the investigation on electrocatalytic materials, and the deep understanding of the underlying reaction mechanisms. Finally, some insights into the scientific challenges now standing in the way of future advancement of the hybrid water electrolysis technique are shared, in the hope of inspiring further innovative efforts in this rapidly growing field.This article is protected by copyright.
