“…Under visible‐light irradiation, band bending occurred and the electrons were transferred onto ZnO to reduce CO 2 , resulting in outstanding CO 2 conversion performance (Figure 6c). Similarly, Pan et al [ 13 ] reported a CeO 2 /CuO p–n junction catalyst, which showed boosted visible‐light absorption and increased carrier concentration. Under light illumination, the photocurrent density increased rapidly, indicating the more effective separation of electrons and holes over the CeO 2 nanoparticles (NPs)/CuO NPs (Figure 6d).…”

“…Thus, the methanol generation in PEC process was higher than PC and EC process. Pan et al [ 13 ] increased the carrier concentration ≈10 8 times by constructing CeO 2 /CuO/Cu p–n heterojunction comparing with CuO nanoparticles/Cu catalyst, reserving sufficient carriers to reduce CO 2 and achieving ≈5 times enhancement of methanol production rate at −1.0 V (vs saturated calomel electrode).…”

Artificial photosynthesis of clean fuels shows fascinating prospects for solving the energy crisis and environmental pollution. However, the solar conversion efficiency is too low to fulfill industrialization requirements, which is confined by the poor photon utilization, severe recombination of electrons and holes, and insufficient reactive sites. Fortunately, junction engineering displays outstanding performance in conquering the aforementioned problems. Herein, an updated fundamental understanding of various junction engineering for enhancing the efficiency, selectivity, and stability of solar‐driven CO2 reduction is provided. The recent progresses of heterojunctions, homojunctions, and multijunctions for photocatalytic (PC) and photoelectrochemical (PEC) CO2 reduction are focused on, especially their essential roles in facilitating the key PC or PEC processes, including charge separation and transfer, adsorption and activation of CO2, and desorption of products, which may provide an interactively referential development pathway for CO2 photoreduction. Finally, an outlook on the current challenges and perspectives of junction engineering design of photocatalysts for solar‐driven CO2 reduction is provided.

“…However, the present issues, such as low selectivity toward a specific product and low FE due to competition with HER and sluggish kinetics, still need to be addressed [76,81,84,85,90,91]. In recent years, various interface-related strategies have been devised to enhance its catalytic performance, such as intermetallic compounds [92], heteroatomic doping [68,93], single Cu atom catalysts [94], core-shell structures [86], and heterostructure [95][96][97]. Among them, alloying is a general and widespread method to improve catalytic performance [98][99][100].…”

Electrocatalytic CO2 reduction reaction (CO2RR) can store and transform the intermittent renewable energy in the form of chemical energy for industrial production of chemicals and fuels, which can dramatically reduce CO2 emission and contribute to carbon-neutral cycle. Efficient electrocatalytic reduction of chemically inert CO2 is challenging from thermodynamic and kinetic points of view. Therefore, low-cost, highly efficient, and readily available electrocatalysts have been the focus for promoting the conversion of CO2. Very recently, interface engineering has been considered as a highly effective strategy to modulate the electrocatalytic performance through electronic and/or structural modulation, regulations of electron/proton/mass/intermediates, and the control of local reactant concentration, thereby achieving desirable reaction pathway, inhibiting competing hydrogen generation, breaking binding-energy scaling relations of intermediates, and promoting CO2 mass transfer. In this review, we aim to provide a comprehensive overview of current developments in interface engineering for CO2RR from both a theoretical and experimental standpoint, involving interfaces between metal and metal, metal and metal oxide, metal and nonmetal, metal oxide and metal oxide, organic molecules and inorganic materials, electrode and electrolyte, molecular catalysts and electrode, etc. Finally, the opportunities and challenges of interface engineering for CO2RR are proposed.

“…Most of these techniques conduct the gas phase's catalytic reaction and result in efficient performance. The fast development of photovoltaic technologies enables the efficient conversion of solar energy into renewable electricity; therefore, the photoelectrocatalysis can also be considered the indirect utilization of solar energy 24,25 . Owning to the particular requirement of the photoelectrochemical setup, in which the reaction usually occurs over the interfaces between electrodes and electrolyte/gas feedstock.…”
