Facile and scalable synthesis of Cu2O-SnO2 catalyst for the photoelectrochemical CO2 conversion
نویسندگان
چکیده
CO2 conversion into high-value-added products is becoming increasingly attractive to find substitutes for fossil-based ones and tackle the environmental crisis. Herein, a noble, simple, reproducible, scalable Cu2O-SnO2 photo-electrocatalyst was synthesized characterized. Coupling cuprous oxide with tin allowed protecting unstable Cu+1 species from photo-corrosion. Evidence of SnO2 stabilization role were found via chronoamperometry tests under chopped light XPS analysis. An optimized catalytic ink developed prepare photocathodes. The photo-electroreduction demonstrated prevalent production CO formate Faradaic efficiencies 35.47 % 19.58 %, respectively, good system stability. Sunlight illumination play major hinder H2 evolution promote ≥C1+ formation.

متن کاملCu2O Photocathode for Low Bias Photoelectrochemical Water Splitting Enabled by NiFe-Layered Double Hydroxide Co-Catalyst
Layered double hydroxides (LDHs) are bimetallic hydroxides that currently attract considerable attention as co-catalysts in photoelectrochemical (PEC) systems in view of water splitting under solar light. A wide spectrum of LDHs can be easily prepared on demand by tuning their chemical composition and structural morphology. We describe here the electrochemical growth of NiFe-LDH overlayers on C...
متن کاملUltraefficient homogeneous catalyst for the CO2-to-CO electrochemical conversion.
A very efficient electrogenerated Fe(0) porphyrin catalyst was obtained by substituting in tetraphenylporphyrin two of the opposite phenyl rings by ortho-, ortho'-phenol groups while the other two are perfluorinated. It proves to be an excellent catalyst of the CO2-to-CO conversion as to selectivity (the CO faradaic yield is nearly quantitative), overpotential, and turnover frequency. Benchmark...
