“…Sulfur vacancies have also been studied. For example, Li et al fabricated sulfur vacancy rich CuIn 5 S 8 atomic layers that contained charge‐enriched Cu–In dual sites and showed highly selective activity toward production of CH 4 . DFT computations on CuIn 5 S 8 showed charge enrichment around In and Cu atoms adjacent to sulfur vacancy.…”

Photocatalytic CO2 reduction is an effective means to generate renewable energy. It involves redox reactions, reduction of CO2 and oxidation of water, that leads to the production of solar fuel. Significant research effort has therefore been made to develop inexpensive and practically sustainable semiconductor‐based photocatalysts. The exploration of atomic‐level active sites on the surface of semiconductors can result in an improved understanding of the mechanism of CO2 photoreduction. This can be applied to the design and synthesis of efficient photocatalysts. In this review, atomic‐level reactive sites are classified into four types: vacancies, single atoms, surface functional groups, and frustrated Lewis pairs (FLPs). These different photocatalytic reactive sites are shown to have varied affinity to reactants, intermediates, and products. This changes pathways for CO2 reduction and significantly impacts catalytic activity and selectivity. The design of a photocatalyst from an atomic‐level perspective can therefore be used to maximize atomic utilization efficiency and lead to a high selectivity. The prospects for fabrication of effective photocatalysts based on an in‐depth understanding are highlighted.

“…Typical p-block metal indium was specifically introduced due to the capability of tuning the electronic structure and dband center of raw catalyst. [19][20][21][22][23] It can be expected that the introduction of indium as the secondary metal in antiperovskite can modulate its adjacent Co catalytic properties.…”

“…It is said that this modification facilitates the donation of electrons to adsorbates such as oxygen, [57,58] therefore making the hydrogenation step easier on the catalyst surface.Besides,the current calculation results indicate that Indium elements do not participate in the reaction, however it should be noted that indium can be active sites for adsorbing O, reported in aCO 2 electroreduction work. [21] Besides,wenotice that the pelectron of In has much higher density than its d-electron ( Figure S17). Their p-electron might have influence on total d band structure yet this needs further debate.…”

Antiperovskite Co 3 InC 0.7 N 0.3 nanomaterials with highly enhanced oxygen reduction reaction (ORR) performance were prepared by tuning nitrogen contents through am etal-organic framework (MOF)-derived strategy.T he nanomaterial surpasses all reported noble-metal-free antiperovskites and even most perovskites in terms of onset potential (0.957 Va tJ = 0.1 mA cm À2 )a nd half-wave potential (0.854 V). The OER and zinc-air battery performance demonstrate its multifunctional oxygen catalytic activities.D FT calculation was performed and for the first time,a4e À dissociative ORR pathway on (200) facets of antiperovskite was revealed. Free energy studies showed that nitrogen substitution could strengthen the OH desorption as well as hydrogenation that accounts for the enhanced ORR performance.T his work expands the scope for material design via tailoring the nitrogen contents for optimal reaction free energy and hence performance of the antiperovskite system.

“…Steady-state PL spectroscopy is a persuasive method to study the charge-separation-recombination efficiency. [44] Figure 4 e exhibits the PL spectra of Ru-bpy with different samples added. It can be seen that with the existence of UNWs, the intensity of PL of Ru-bpy became the lowest, indicating the higher-efficiency charge separation between Ru-bpy and catalysts.…”

Utilizing sustainable energy for chemical activation of small molecules, such as CO2, to produce important chemical feedstocks is highly desirable. The simultaneous production of CO/H2 mixture (syngas) from photoreduction of CO2 and H2O is highly promising. However, the relationships between structure, composition, crystallinity, and photocatalytic performance are still indistinct. Here, amorphous ultrathin CoO nanowires and polyoxometalate incorporated nanowires with even lower crystallinity were synthesized. The POM‐incorporated ultrathin nanowires exhibit high photocatalytic syngas production activity, reaching H2 and CO evolution rates of 11555 and 4165 μmol g−1 h−1 respectively. Further experiments indicate that the ultrathin morphology and incorporation of POM both contribute to the superior performance. Multiple characterizations reveal the enhanced charge–hole separation efficiency of the catalyst would facilitate the photocatalysis.
