“…The corresponding Tafel plots were calculated by the equation of η = b log j + a. Nyquist plots were obtained through electrochemical impedance spectroscopy (EIS) with a frequency range from 1 Hz to 100 kHz and an AC amplitude of 5 mV. Electrochemical double-layer capacitance (C dl ) was measured by CV curves under various sweep speeds (20,40,60,80, 100, and 120 mV s −1 ) in a non-faradaic voltage region. All the electrochemical curves were collected until the test results remained constant at room temperature (∼25 °C).…”

“…17 To address these issues, a strategy of organic-assisted water electrolysis has been developed for H 2 production. 18 Oxidation of some sacrificial organic materials such as urea, 19,20 hydrazine, [21][22][23] and ammonia 24,25 that have lower potentials than the OER in the electrolysis process can efficiently decrease the voltage input and thus electricity consumption, but the high-cost sacrificial agents with low value-added gas products (N 2 ) or greenhouse gas (CO 2 ) can also lead to the loss of economic benefits. So, the electrochemical oxidation synthesis of high value-added chemicals from suitable electrondonating organic materials such as glucose, 26,27 hydroxymethylfurfural (HMF), [28][29][30][31] and alcohols 32 to replace the OER process seems more favorable and competitive, and it not only decreases the voltage input, but can also afford high valueadded anodic products without other gas emission.…”

“…Thus, in the line of preparation of MOFs to combine with PNCs, Huang and co‐workers [ 81 ] have fabricated hierarchical photoanodes based on MOFs derivatives N‐doped carbon TiO 2 /CsPbBr 3 /TiO 2 nanorods (TiO 2 (N‐C)/CPB/TiO 2 ) to perform the PEC glycerol oxidation into added‐value products.

Global warming and ecosystems contamination by fine chemicals industry have motivated to explore and develop cleaner and lower cost strategies for the energy conversion and transformation of organic compounds. [1,2] Solar-driven catalysis via photo(electro)catalysis (PEC) has emerged as a promising route to store sunlight into chemical bonds. Commonly, PEC water splitting has been studied as an approach to reduce H þ to produce green hydrogen with the oxygen evolution reaction (OER) as electron donor. As this reaction is kinetically very demanding, water can be substituted by organic compounds as electron donors due to their faster oxidation kinetics. This would increase the H 2 evolution kinetics while concomitantly producing high added-value chemicals, remediating industrial wastewaters, [3][4][5][6][7][8] and making use of semiconductor materials with highly oxidizing/ reducing power. [8,9] In a simple manner, when a semiconductor is illuminated with an energy equal or higher than its bandgap, charge carrier photogeneration and separation is promoted. Photogenerated holes are formed in the valence band (VB), where oxidation reactions take place, while electrons with higher free energy are located in the conduction band (CB) to trigger reduction reactions. [9][10][11] This is the basis of photocatalytic (PC) reactions led through nanoparticle system (Figure 1A). Then, when the photomaterial is deposited in a conducting substrate, PEC oxidation and reduction reactions can be carried out in separate compartments. [9,12,13] Here, one type of photocarriers migrate to the photoelectrode surface to conduct an interfacial PEC semireaction, while the other kind of photocarrier is transported through the external circuit to a counter electrode and perform the complementary PEC semireaction (Figure 1B). [9] Metal oxides, chalcogenides, and heterojunctions based on these materials have attracted significant attention as photocatalysts due to their wide gamut of low-cost synthetic protocols available for their preparation and facile charge carrier extraction [9,10,[13][14][15][16] Although metal oxide photoelectrodes show a high performance under UV light, high stability, and low toxicity in some cases, they are often limited by their poor light harvesting efficiency toward near-infrared wavelengths. Additionally, metal oxide photoelectrodes tend to exhibit a fast carrier recombination as well as poor charge accumulation/transport kinetics, hindering their applicability in solar water splitting applications. [10,17,18] In the case of chalcogenides, their superior optoelectronic properties are in contrast with the low stability promoted by their fast photodegradation. To reduce photodegradation and charge carrier recombination and to overcome charge transport/accumulation kinetic limitations, inner-sphere redox couples and organic substrates are commonly used to accelerate

Owing to their remarkable and adjustable optoelectronic properties, halide perovskites (HPs) have been regarded as a class of promising materials for various optoelectronic applications based on different energy conversion reactions, including photovoltaic cell, photocatalysis, electrocatalysis, and photoelectrochemical (PEC) systems. However, the low stability of HPs upon exposure to ambient conditions (e.g., water, heat, light, electricity) greatly hinders the practical applications of HPs. In the past few years, significant efforts have been devoted to enhancing the eventual stability of the perovskite‐based optoelectronic systems, mainly focusing on delivering improvements in the stabilities of halide perovskite materials and the relevant operation conditions of optoelectronic systems, which deserve in‐depth and systematic summaries. In this comprehensive review, the in‐depth environment‐induced decomposition mechanisms of typical HPs are elucidated. Simultaneously, the strategies for addressing the instability issues of halide perovskite materials are critically reviewed, including dimension control, compositional engineering, ligand passivation, and encapsulation engineering. Furthermore, the photoelectric applications based on the modified HPs and operation conditions are discussed systematically. In the last part of this review, future perspectives and outlooks toward the stability of HPs and their photoelectric applications are envisaged respectively.
