“…Previous experimental and theoretical works have investigated the structural, electronic, and chemical characteristics of a few monolayer phases of GaSe 22 , GaTe 23 , ZnSe 19,[24][25][26][27][28][29][30][31][32] , ZnTe 29,30,32 , and SiAs [33][34][35] . 2D layers of ZnSe in various structural forms have attracted attention for their photoabsorption properties 24,36 , as have low-dimensional forms of ZnTe bound to nanowires or in nanoparticle form [37][38][39] . However, to our knowledge, none of the 2D systems we consider have been studied for CO 2 photoelectrocatalyst applications.…”

Photoelectrocatalysts that use sunlight to power the CO 2 reduction reaction will be crucial for carbon-neutral power and energyefficient industrial processes. Scalable photoelectrocatalysts must satisfy a stringent set of criteria, such as stability under operating conditions, product selectivity, and efficient light absorption. Two-dimensional materials can offer high specific surface area, tunability, and potential for heterostructuring, providing a fresh landscape of candidate catalysts. From a set of promising bulk CO 2 reduction photoelectrocatalysts, we screen for candidate monolayers of these materials, then study their catalytic feasibility and suitability. For stable monolayer candidates, we verify the presence of visible-light band gaps, check that band edges can support CO 2 reduction, determine exciton binding energies, and compute surface reactivity. We find visible light absorption for SiAs, ZnTe, and ZnSe monolayers, and that due to a lack of binding, CO selectivity is possible. We thus identify SiAs, ZnTe, and ZnSe monolayers as targets for further investigation, expanding the chemical space for CO 2 photoreduction candidates.

Colloidal semiconductor nanocrystals (NCs), especially cadmium (Cd)‐ and lead (Pb)‐containing ones, have been proved to be the promising materials for photoelectronic energy conversion applications. However, the high toxicity and cost of these materials restrict their widespread use. Zinc (Zn)‐containing colloidal semiconductor NCs are non‐/less toxic and environmentally friendly materials, manifesting in stimulating optical and electronic properties with relevance to a broad scope of applications including light‐emitting diodes (LEDs), sensors, photocatalysts, and more. In this Review, we elaborate on the shape control of Zn‐containing colloidal semiconductor NCs achieved by a variety of wet‐chemical synthetic approaches. Moreover, the formation of core‐shell, doped, and hybrid structures based on Zn‐containing colloidal semiconductor NCs allow for the optimization of their functionalities, which underpin stimulating photoelectronic energy conversion applications in quantum‐dot LEDs (QLEDs), photodetectors, and photocatalysis. Zn‐containing colloidal semiconductor NCs that combine the green chemistry with sustainable developments possess a bright future.
