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.

“…For example, Jin et al. synthesized atomically precise [Au 25 (XR) 18 ] − nanoclusters with the same Au 25 kernel but different protecting ligands (−XR, X=S or Se, R: carbon tail) and found that the anchoring atom (S or Se) of the ligand strongly affects the selectivity of the CO 2 RR (Figure 9 a, b) [38] . CO is the main product when S is the anchoring atom on the surface of the Au nanoclusters, while the hydrogen evolution reaction (HER) becomes more favorable with the anchoring atom of Se.…”

Noble metal nanocrystals are a family of important catalysts for a broad range of processes (especially electrocatalytic ones), which are usually obtained as a hybrid each containing a metallic core and a ligand shell. It is well recognized that the ligand plays a critical role in regulating the crystal growth into different shapes and maintaining the colloidal stability of the nanocrystals. Recently, more effects of the ligand were revealed in controlling both the synthesis and the surface property of noble metal nanocrystals, which could be maneuvered to achieve distinctive catalytic properties. In this review, we present a summary of the roles of the ligand based on typical results from the literature. The review begins with a discussion on the roles of the ligand in the controlled synthesis of noble metal nanocrystals, including the shape control, the reduction potential control for suppressing self-nucleation and galvanic replacement reaction, and the electroless plating effect for noble metal/non-noble metal co-reduction. The following section includes a discussion of the effects of the ligand on the surface property of noble metal nanocrystals, including the ensemble size engineering, the ligand-metal electron transfer, and the local microenvironment construction, toward designable electrocatalytic properties. At the end, we provide our perspectives on the future research of ligand engineering as an advanced technique for tailoring electrocatalytic properties of noble metal nanocrystals.

The magnetic properties of Au nanoparticles (NPs) have long been an intriguing topic in fundamental research. In the quantum size regime (1–3 nm), Au NPs indeed exhibit distinct magnetism in contrast to diamagnetic gold in bulk or relatively large plasmonic NPs. However, previous studies often give controversial results due to imprecise NPs used in magnetic studies, making it difficult to understand the origin of magnetism in Au NPs. Recent progress has led to atomically precise Au nanoclusters (NCs for differentiation with regular NPs), which can serve as a unique model for studying the delocalized spin in isolated NCs and the spin–spin exchange interaction between NCs in assembled solids. Moreover, such mechanisms are correlated to the atomic structures of the magnetic NCs. The precise formulas of the NCs serve as a clear indicator for magnetism. So far, the Au-thiolate NCs reported to be magnetic, including the doped ones, all contain icosahedral kernel structures, which are facile compared to other structures in adding or removing one electron for endowing magnetism to the NCs. Heteroatom doping in the NCs is an effective method to probe the magnetic mechanism in NCs, such as the origin of magnetic anisotropy, and the counterion tailoring for those charged NCs can also impart magnetism to the initially diamagnetic NCs via stabilizing a particular charge state of the NCs. While only a few cases of NCs have been reported with magnetism thus far, future research on metal NCs (especially in the critical regime between molecular and metallic state) will reveal more fundamentals of magnetism, and the control of spin–spin exchange coupling in nanocluster-assembled solids is particularly promising for tailoring the magnetic functionality of NCs and ultimately finding versatile applications.
