“…It follows that coupling high-performance eCO 2 RR systems and photoabsorbers does not necessarily lead to a high-performance artificial leaf. An integral design approach among different disciplines, focused on matching energy band gaps and kinetic overpotentials with dedicated interface engineering, is thus prerequisite . In this respect, examples of current efforts are the Joint Centre for Artificial Photosynthesis in the United States or the a-leaf project funded by the European Union…”

In recent years, screening of materials has yielded large gains in catalytic performance for the electroreduction of CO. However, the diversity of approaches and a still immature mechanistic understanding make it challenging to assess the real potential of each concept. In addition, achieving high performance in CO (photo)electrolyzers requires not only favorable electrokinetics but also precise device engineering. In this Perspective, we analyze a broad set of literature reports to construct a set of design-performance maps that suggest patterns between performance figures and different classes of materials and optimization strategies. These maps facilitate the screening of different approaches to electrocatalyst design and the identification of promising avenues for future developments. At the device level, analysis of the network of limiting phenomena in (photo)electrochemical cells leads us to propose a straightforward performance metric based on the concepts of maximum energy efficiency and maximum product formation rate, enabling the comparison of different technologies.

“…TiO 2 is the most investigated semiconductor material for photocatalytic processes. It is a ntype semiconductor that possesses a wide band gap (3.0 eV) 8 and has been considered a cheaper and more environmental friendly material since the first report in 1979. 85 TiO 2 has three kinds of polycrystalline phases, (anatase, brookite, and rutile), 86 with different symmetries, slip directions, theoretical crystal densities, close stacking planes, and available interstitial positions, altering also the defect distribution and density.…”

“…The goal is to use excited electrons that are generated when the semiconductor absorbs light to effect electrochemistry on a redox couple strategically chosen to produce the desired chemicals. 8 The concept of a photoelectrochemical cell is comparable to a conventional electrochemical cell, except that energy necessary to cause redox reactions is partially provided by the light. This concept is represented in Figure 1.…”

Solar‐driven photoelectrochemical (PEC) CO2 conversion to valuable chemicals, combining the advantages of photocatalysis and electrocatalysis, represents a promising approach towards establishing a carbon‐neutral society and harnessing solar energy. Photoelectrode materials doped with metals and/or non‐metals have shown promise in achieving high CO2 reduction efficiency. Metal or non‐metal doping entails introducing a heteroelement into the semiconductor, thereby modifying the band potentials of the semiconductor through the addition of a defective state. This alteration may improve the charge transfer kinetics of the catalysis. Furthermore, doping aids in creating active CO2 adsorption offers anchoring sites for CO2 molecules, and can promote product selectivity. This review aims to provide a concise summary of elemental‐doped photoelectrodes for converting CO2 into fuels through photoelectrochemical processes. We discuss several key factors affecting the performance of PEC CO2 reduction, including the interaction of reactants with catalysts, reaction conditions, and the impact of the photoelectrode. Moreover, we discussed various PEC CO2 reduction systems, with a specific focus on enhancing the efficiency of CO2 reduction. Finally, we provide a summary of key considering aspects for further development of the PEC CO2 reduction.This article is protected by copyright. All rights reserved.
