“…Tremendous effort has been made to develop photocatalysts with high activity under visible light irradiation, and it is primarily important to tailor the band structure . A hybrid organic/inorganic compound with a MOF structure, Cu 3 PO 4 (C 2 N 3 H 2 ) 2 OH, which was synthesized by hydrothermal route in the presence of 1,2,4‐triazole as a structure directing agent, was investigated as a photocatalyst for the OER under visible light . This Cu‐based MOF had a band gap of 2.58 eV, which ensured visible‐light‐driven photocatalytic activity.…”

The development of clean and renewable energy materials as alternatives to fossil fuels is foreseen as a potential solution to the crucial problems of environmental pollution and energy shortages. Hydrogen is an ideal energy material for the future, and water splitting using solar/electrical energy is one way to generate hydrogen. Metal‐organic frameworks (MOFs) are a class of porous materials with unique properties that have received rapidly growing attention in recent years for applications in water splitting due to their remarkable design flexibility, ultra‐large surface‐to‐volume ratios and tunable pore channels. This review focuses on recent progress in the application of MOFs in electrocatalytic and photocatalytic water splitting for hydrogen generation, including both oxygen and hydrogen evolution. It starts with the fundamentals of electrocatalytic and photocatalytic water splitting and the related factors to determine the catalytic activity. The recent progress in the exploitation of MOFs for water splitting is then summarized, and strategies for designing MOF‐based catalysts for electrocatalytic and photocatalytic water splitting are presented. Finally, major challenges in the field of water splitting are highlighted, and some perspectives of MOF‐based catalysts for water splitting are proposed.

“…As seen from Figure 17d, the O 2 evolution performance of Cu 3 PO 4 (C 2 N 3 H 2 ) 2 OH reached ≈4.2 mL after 1 h photoirradiation with the addition of sulfite as sacrificial agent. [113] As introduced above, the bismuth-based photocatalysts have become a series of potential materials for water oxidation due to the abundant resources and environment-friendly feature. Bi 3+ ions easily coordinate with the organic ligands, so the Bi-based MOFs are ideal candidates worth to be explored.…”

Photocatalytic water splitting has attracted a lot of attention in recent years, and O 2 evolution is the decisive step owing to the complex four-electrons reaction process. Though many studies have been conducted, it is necessary to systematically summarize and introduce the research on photocatalytic O 2 evolution, and thus a systematic review is needed. First, the corresponding principles about O 2 evolution and some urgently encountered issues based on the fundamentals of photocatalytic water splitting are introduced. Then, several types of classical water oxidation photocatalysts, including TiO 2 , BiVO 4 , WO 3 , 𝜶-Fe 2 O 3 , and some newly developed ones, such as Sillén-Aurivillius perovskites, porphyrins, metal-organic frameworks, etc., are highlighted in detail, in terms of their crystal structures, synthetic approaches, and morphologies. Third, diverse strategies for O 2 evolution activity improvement via enhancing photoabsorption and charge separation are presented, including the cocatalysts loading, heterojunction construction, doping and vacancy formation, and other strategies. Finally, the key challenges and future prospects with regard to photocatalytic O 2 evolution are proposed. The purpose of this review is to provide a timely summary and guideline for the future research works for O 2 evolution.

“…In the following year, Lin and co‐workers [ 42 ] modified UiO‐67 by creating side‐chains on biphenyl‐dicarboxylic acids, and UiO‐67 with the incorporated [Ir III (Cp*)–(dcppy)] (Cp* = pentamethylcyclopentadienyl, dcppy = 2‐phenylpyridine‐5,4′‐dicarboxylic acid) delivered high turnover frequency (TOF) toward water oxidation. Research for pure MOFs as water oxidation catalysts (WOCs) underwent a rapid expansion since late 2013 with [Co 4 L 2 (4,4′‐bpy)(H 2 O) 6 ]⋅3.5H 2 O and [Co 2 L(azene)(H 2 O) 3 ]⋅DMF, [ 43 ] [Cu 3 PO 4 (C 2 N 3 H 2 ) 2 OH], [ 44 ] Co‐ZIF‐9 [ 45 ] appeared successively. In late 2014, insightful water dissociation mechanism on pure Zn‐MOF‐74 was provided by Thonhauser and co‐workers, [ 46 ] demonstrating the contribution of unsaturated metal sites in MOFs to water molecule splitting.…”

Increasing demand for sustainable and clean energy is calling for the next‐generation energy conversion and storage technologies such as fuel cells, water electrolyzers, CO2/N2 reduction electrolyzers, metal–air batteries, etc. All these electrochemical processes involve oxygen electrocatalysis. Boosting the intrinsic activity and the active‐site density through rational design of metal–organic frameworks (MOFs) and metal–organic gels (MOGs) as precursors represents a new approach toward improving oxygen electrocatalysis efficiency. MOFs/MOGs afford a broad selection of combinations between metal nodes and organic linkers and are known to produce electrocatalysts with high surface areas, variable porosity, and excellent activity after pyrolysis. Some recent studies on MOFs/MOGs for oxygen electrocatalysis and their new perspectives in synthesis, characterization, and performance are discussed. New insights on the structural and compositional design in MOF/MOG‐derived oxygen electrocatalysts are summarized. Critical challenges and future research directions are also outlined.
