“…Recently, there have been many reviews on CO 2 electroreduction, but most of them focus on CO 2 electroreduction to CO, 14,15 HCOOH, 16,17 or C 2+ products, [18][19][20] and few of them focus on CH 4 production by CO 2 electroreduction. This review provides a systematic summary of the recent progress and future opportunities for CO 2 electroreduction into CH 4 .…”

“…Renewable electricity-driven electrochemical reduction reaction of CO 2 (CO 2 RR) to upgraded chemicals can simultaneously mitigate the overwhelming carbon footprint and store intermittent energy for use on demand (1)(2)(3)(4). In the past decade, continuous efforts have been devoted to pushing the performance boundary toward the critical point of economic benefit to meet the commercialization request, especially C 1 and C 2 products, like CO (5,6), formic acid (7,8), and ethylene (9).…”

Oxide-derived copper (OD-Cu) is the most efficient and likely practical electrocatalyst for CO 2 reduction toward multicarbon products. However, the inevitable but poorly understood reconstruction from the pristine state to the working state of OD-Cu under strong reduction conditions largely hinders the rational construction of catalysts toward multicarbon products, especially C 3 products like n-propanol. Here, we simulate the reconstruction of CuO and Cu 2 O into their derived Cu by molecular dynamics, revealing that CuO-derived Cu (CuOD-Cu) intrinsically has a richer population of undercoordinated Cu sites and higher surficial Cu atom density than the counterpart Cu 2 O-derived Cu (Cu 2 OD-Cu) because of the vigorous oxygen removal. In situ spectroscopes disclose that the coordination number of CuOD-Cu is considerably lower than that of Cu 2 OD-Cu, enabling the fast kinetics of CO 2 reaction and strengthened binding of *C 2 intermediate(s). Benefiting from the rich undercoordinated Cu sites, CuOD-Cu achieves remarkable n-propanol faradaic efficiency up to ~17.9%, whereas the Cu 2 OD-Cu dominantly generates formate.

“…Escalating concern toward a green and sustainable society urgently requires us to recycle or upgrade the waste carbon resources (polymers, CO 2 , and so forth) into value-added chemicals. − Plastic, especially polyethylene terephthalate (PET) with an annual production of 70 million tons, is widely used for daily packaging and textile. Unfortunately, only about 20% of PET plastic products are recycled, and most of them are landfilled or discarded, which not only induces environmental pollution but also causes a huge waste of carbon resources .…”

Polyethylene terephthalate (PET) plastic and CO 2 pollution have seriously threatened the ecological environment and caused a huge waste of carbon resources. Herein, we report an electrocatalytic waste-treating-waste strategy for concurrently upgrading PET plastic and CO 2 wastes into value-added formic acid (HCOOH), in which both the anode (oxygen-vacancy-rich Ni(OH) 2 -V O ) and cathode (Bi/Bi 2 O 3 heterostructure) electrocatalysts were elaborately designed from PET derivatives. Impressively, the as-prepared Ni(OH) 2 -V O and Bi/Bi 2 O 3 achieve high selectivity of HCOOH (86 and 91%, respectively) with industrial-level current densities at ultralow potentials (300 mA cm −2 at 1.6 V and −272 mA cm −2 at −1.4 V, respectively). Further experimental and theoretical results reveal that the abundant oxygen vacancies will largely facilitate the formation of Ni 3+ species and accelerate the subsequent processes of dehydrogenation and C−C bond breakage during PET upcycling. Meanwhile, the interface electron transfer from Bi 2 O 3 to Bi benefits the keeping of high valence of Bi sites and optimizes the adsorption of OCHO* intermediate, thereby endowing Bi/Bi 2 O 3 with efficient performance toward CO 2 reduction to HCOOH. As a proof of concept, a solar-powered flow reactor with real-time monitoring and control functions was designed, which realized a record Faradaic efficiency of 181% for HCOOH. This work offers opportunities for waste utilization and provides constructive guidance for the design of advanced electrocatalysts for converting wastes into valuable chemicals.
