However, the traditional oxygen evolution reaction (OER) occurring at the (photo)anode is hindered by high thermodynamic demands and sluggish kinetics, resulting in excessive energy consumption and limited economic value of the O₂ produced, thereby impeding the practical application of PEC reactions. To overcome these limitations, advanced anodic-cathodic coupling systems, as an emerging energy conversion technology, have garnered significant research interest. These systems substitute OER with lower potential, valuable oxidation reactions, significantly enhancing energy conversion efficiency, yielding high-value chemicals, while reducing energy consumption and environmental pollution. More importantly, by designing and optimizing photoelectrodes to generate sufficient photovoltage under illumination, meeting the thermodynamic and kinetic potential requirements of the reactions, and by tuning the voltage to match the current densities of the cathode and anode, coupling reactions can be achieved under bias-free conditions. In this review, we provide an overview of the mechanisms of PEC coupling reactions and summarize photoelectrode catalysts along with their synthesis methods. We further explore advanced catalyst modification strategies and highlight the latest development in advanced PEC coupling systems, including photocathodic CO₂ reduction, nitrate reduction, oxygen reduction, enzyme activation, coupled with photoanodic organic oxidation, biomass oxidation, and pollutant degradation. Additionally, advanced <em>in situ</em> characterization techniques for elucidating reaction mechanisms are discussed. Finally, we propose the challenges in catalyst design, reaction systems, and large-scale applications, while offering future perspectives for PEC coupling system.

However, the photocatalytic efficiency is often hindered by the inefficient charge separation and rapid recombination of photo-induced charge carriers, both are strongly affected by the electronic structure of the co-monomers in polymer photocatalysts. In this study, we design three conjugated porous polymers with distinct electronic architectures by combining dibenzo[g,p]chrysene (DBC) and benzene with different substituted groups. The results demonstrate that the combination of DBC and the unsubstituted benzene forms a donor-donor (D-D) structure due to their similar energy levels, while the introduction of methoxy enhances the electron-donating ability of benzene ring, leading to a reinforced D-D structure between DBC and the methoxy-substituted benzene unit, which suppresses the charges separation. In contrast, the introduction of electron-withdrawing cyano group significantly enhances the electron receptivity of the benzene unit, leading to the formation of donor-acceptor (D-A) structure between DBC and the cyano-substituted benzene unit, promoting charges transfer and separation of light-induced electrons and holes. As a result, the D-A polymer DBC-BCN achieves an impressive hydrogen evolution rate (HER) of 20.67 mmol h^–1 g^–1 under UV-Vis light irradiation, outperforming the D-D polymers of DBC-BMO (2.13 mmol h^–1 g^–1) and DBC-B (13.10 mmol h^–1 g^–1).

The WGS reaction occurs very readily on ZnAl₂O₄ surface whereas which is less active towards alkane formation <em>via</em> olefin hydrogenation, and the latter can be attributed to the characteristics of the H₂ heterolytic activation and the weak polarity of olefins. The driving effect of zeolite component towards CO conversion was demonstrated by microkinetic simulations, which is sensitive to reaction conditions like space velocity and reaction temperature. Under a fixed ratio of active sites between oxide and zeolite components, the concept of the “impossible trinity” of high CO conversion, high olefin selectivity, and high space velocity can thus be manifested.
