Establishing the Role of Operating Potential and Mass Transfer in Multicarbon Product Generation for Photoelectrochemical CO2 Reduction Cells Using a Cu Catalyst

“…Prior PEC CO 2 R work has focused primarily on photocathodes producing single-carbon (C 1 ) products; ,,,, however, the production of multicarbon (C 2+ ) products is more attractive because of their higher energy density, large market demand, and compatibility with an established infrastructure. , Copper (Cu) has the unique ability to catalyze CO 2 R to C 2+ products with high faradaic efficiency (FE), , leading to its examination for PEC CO 2 R. ,, While various Cu-based oxides and chalcogenides have been investigated as photocathodes, these materials produce primarily H 2 and C 1 products . Alternatively, photocathodes containing metallic Cu deposited on a semiconductor were reported to generate C 2+ products at appreciable rates and selectivities. ,, …”

“…23 Alternatively, photocathodes containing metallic Cu deposited on a semiconductor were reported to generate C 2+ products at appreciable rates and selectivities. 21,23,26 The product distribution of electrochemical CO 2 R on Cu is highly potential-dependent, 25 as is that of PEC CO 2 R on the photocathode potential. 21,27 This inherent potential-dependent selectivity presents challenges for the design and operation of PEC CO 2 R systems that are distinct from those for PEC systems designed for water splitting.…”

Progress and perspectives on 1D nanostructured catalysts applied in photo(electro)catalytic reduction of CO2

“…Souza et al loaded Cu, Pd, and Pt on GNRs in different ratios and deposited them on TNTs as photocathodes for reducing CO 2 to CH 3 OH and CH 3 CH 2 OH. 242 Similarly, Ru et al supported Pd NPs and reduced graphene oxide (RGO) onto TNTs grown on Ti wires (Fig. 27(f)).…”

Emerging Single-Atom Catalysts and Nanomaterials for Photoelectrochemical Reduction of Carbon Dioxide to Value-Added Products: A Review of the Current State-of-the-Art and Future Perspectives

“…The synthesis of the electrode material using different metallic combinations of Pt, Pd, and Cu strongly anchored on graphene nanoribbons (GNRs) was carried out for the PEC reduction of CO 2 . These NMTs were then deposited on the TiO 2 -NT surface.…”
