Nitrate is a reasonable alternative instead of nitrogen for ammonia production due to the low bond energy, large water‐solubility, and high chemical polarity for good absorption. Nitrate electroreduction reaction (NO3RR) is an effective and green strategy for both nitrate treatment and ammonia production. As an electrochemical reaction, the NO3RR requires an efficient electrocatalyst for achieving high activity and selectivity. Inspired by the enhancement effect of heterostructure on electrocatalysis, Au nanowires decorated ultrathin Co3O4 nanosheets (Co3O4‐NS/Au‐NWs) nanohybrids are proposed for improving the efficiency of nitrate‐to‐ammonia electroreduction. Theoretical calculation reveals that Au heteroatoms can effectively adjust the electron structure of Co active centers and reduce the energy barrier of the determining step (*NO → *NOH) during NO3RR. As the result, the Co3O4‐NS/Au‐NWs nanohybrids achieve an outstanding catalytic performance with high yield rate (2.661 mg h−1 mgcat−1) toward nitrate‐to‐ammonia. Importantly, the Co3O4‐NS/Au‐NWs nanohybrids show an obviously plasmon‐promoted activity for NO3RR due to the localized surface plasmon resonance (LSPR) property of Au‐NWs, which can achieve an enhanced NH3 yield rate of 4.045 mg h−1 mgcat−1. This study reveals the structure–activity relationship of heterostructure and LSPR‐promotion effect toward NO3RR, which provide an efficient nitrate‐to‐ammonia reduction with high efficiency.

“…This effect can be elucidated as the synchronized oscillation of valence electrons triggered by resonant photons. 66 This interaction engenders distinctive attributes within plasmonic metals, including the formation of localized electromagnetic fields, the generation of high-energy "hot" electrons and holes, as well as the release of heat and thermal radiation. 67 In the realm of photocatalysis, plasmonic metals can serve as adept light-harvesting components, generating active charge carriers that kick-start the desired chemical reactions.…”

Recently, there has been a burgeoning interest in photocatalytic CO 2 conversion from the general public and the scientific community. In theory, this technology can harness abundant solar energy to transform waste CO 2 into valuable chemicals, holding the potential to replace certain conventional chemical engineering methods for industrial chemical production in a sustainable and eco-friendly manner. Despite these promising aspects, the practical application of photocatalytic CO 2 conversion has been hampered by its limited activity and selectivity. Numerous efforts have been dedicated to enhancing the activity of photocatalytic CO 2 conversion over the past few decades, driving its progress. However, there has been a noticeable shortage of research focused on improving the selectivity of this process, particularly concerning the generation of high-value C 2+ products. In this Perspective, our primary objective is to delve into recent developments in photocatalytic CO 2 conversion, with a specific emphasis on the production of C 2+ products. Our discussion will commence by elucidating the fundamental principles and mechanisms underlying C−C coupling in this reaction. Subsequently, we will provide an overview of the current techniques available for fine-tuning the selectivity of these reactions toward the formation of C 2+ products. Finally, we will conclude this perspective by offering insights into the prospects and potential advancements in this field.

This review paper presents the recent developments in spectroelectrochemical (SEC) technologies. The coupling of spectroscopy and electrochemistry enables SEC to do a detailed and comprehensive study of the electron transfer kinetics and vibrational spectroscopic fingerprint of analytes during electrochemical reactions. Though SEC is a promising technique, the usage of SEC techniques is still limited. Therefore, enough publicity for SEC is required, considering the promising potential in the analysis fields. Unlike previously published review papers primarily focused on the relatively frequently used SEC techniques (ultraviolet-visible SEC and surface-enhanced Raman spectroscopy SEC), the two not-frequently used but promising techniques (nuclear magnetic resonance SEC and dark-field microscopy SEC) have also been studied in detail. This review paper not only focuses on the applications of each SEC method but also details their primary working mechanism. In short, this paper summarizes each SEC technique’s working principles, current applications, challenges encountered, and future development directions. In addition, each SEC technique’s applicative research directions are detailed and compared in this review work. Furthermore, integrating SEC techniques into microfluidics is becoming a trend in minimized analysis devices. Therefore, the usage of SEC techniques in microfluidics is discussed.
