Professor John B. Goodenough started his research on perovskite‐type oxides working on random‐access memory with ceramic [La,M(II)]MnO3 in the Lincoln Laboratory, Massachusetts Institute of Technology, more than 60 years ago. Since then perovskite‐type oxides have played vital roles in the field of energy conversion and storage. In this review, a brief overview is given on the structure, defect chemistry, and transport properties of perovskite oxides, especially the mixed‐valent materials with mixed electronic and ionic conductivities. The recent advances of perovskite oxides applications in the oxygen reduction reaction, oxygen evolution reaction, electrochemical water splitting reaction, metal–air batteries, solid‐state batteries, oxygen separation membranes, and solid oxide fuel cells are highlighted. Moreover, some novel design strategies for optimizing performance, like interface engineering, defect engineering, strain modulation are discussed as well. Finally, a perspective is given on how to design high‐performance perovskite oxide based materials for energy conversion and storage applications as well as the challenges involved in this task.

“…In various sustainable hydrogen production routes, photoelectrochemical (PEC) water splitting has drawn increasing attention since 1972 . Numerous materials, including Si, g‐C 3 N 4 , metal oxides, metal‐chalcogenides, phosphides, and perovskites, etc., have been employed for PEC water splitting. Especially, metal oxides have shown promising prospects owing to their attractive light‐harvesting ability, redox‐compatible energy levels, low cost, and high repeatability.…”

Cu 2 O is a typical photoelectrocatalyst for sustainable hydrogen production, while the fast charge recombination hinders its further development. Herein, Ni 2+ cations have been doped into a Cu 2 O lattice (named as Ni-Cu 2 O) by a simple hydrothermal method and act as electron traps. Theoretical results predict that the Ni dopants produce an acceptor impurity level and lower the energy barrier of hydrogen evolution. Photoelectrochemical (PEC) measurements demonstrate that Ni-Cu 2 O exhibits a photocurrent density of 0.83 mA cm À2 , which is 1.34 times higher than that of Cu 2 O. And the photostability has been enhanced by 7.81 times. Moreover, characterizations confirm the enhanced light-harvesting, facilitated charge separation and transfer, prolonged charge lifetime, and increased carrier concentration of Ni-Cu 2 O. This work provides deep insight into how acceptordoping modifies the electronic structure and optimizes the PEC process. Developing hydrogen energy plays a critical role in revolutionizing the current fossil-fuel-based energy system.

“…With the gradual intensity of global energy crisis, hydrogen (H 2 ) is one of the most sustainable and clean energies for replacing fossil fuel energy [1,2]. Reforming natural gas to produce H 2 not only consumes a large amount of natural resources but also produces undesired carbon dioxide, which causes greenhouse effect [3][4][5]. Splitting water into H 2 and oxygen (O 2 ) was from more than 200 years ago.…”

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.
