Integrating the nitrate reduction reaction (NO3RR) with polyethylene terephthalate (PET) hydrolysate oxidation to construct nitrate/PET coelectrolysis system holds a great promise of realizing simultaneous upcycling wastewater and PET plastic waste, which, however, is still an almost untouched research area. Herein, we develop ultralow content Ru-incorporated Co-based metal-organic frameworks as bifunctional precatalyst, which can be in situ reconstructed Ru-Co(OH)2 at cathode Ru-CoOOH anode under electrocatalytic environments, function real active catalysts for NO3RR oxidation, respectively. With two-electrode system, current density 50 mA cm-2 achieved cell voltage only 1.53 V, production ammonia formate lower energy consumption. This study provides concept construction systems waste.

Challenges remain in the development of highly efficient catalysts for selective electrochemical transformation carbon dioxide (CO2 ) to high-valued hydrocarbons. In this study, oxygen vacancy-rich Bi2 O3 nanosheets coated with polypyrrole (Bi2 @PPy NSs) are designed and synthesized, as precatalysts electrocatalytic CO2 reduction formate. Systematic material characterization demonstrated that precatalyst can evolve intoBi2 O2 CO3 rich vacancies via electrolyte-mediated conversion function real active catalyst reaction electrocatalysis. Coating a PPy shell modulate interfacial microenvironment sites, which work coordination efficiently mediate directional toward formate formation. With fine-tuning microenvironment, optimized @PPy-2 NSs derived exhibit maximum Faradaic efficiency 95.8% at -0.8 V (versus. reversible hydrogen electrode) production. This might shed some light on designing advanced through local engineering.

Опубликована: Фев. 27, 2024

Abstract The electroreduction of CO 2 to high‐value products is a promising approach for achieving carbon neutrality. Among these products, formic acid stands out as having the most potential industrialization due its optimal economic value in terms consumption and output. In recent years, Faraday efficiency from has reached 90~100 %. However, this high selectivity cannot be maintained extended periods under currents meet industrial requirements. This paper reviews excellent work perspective catalyst stability, summarizing discussing performance typical catalysts. Strategies preparing stable highly active catalysts are also briefly described. review may offer useful data reference valuable guidance future design long‐stability
