Supplementary files for article Synergistic induced charge transfer switch by oxygen vacancy and pyrrolic nitrogen in MnFe2O4/g-C3N4 heterojunctions for efficient transformation of bicarbonate to acetate in photo-assisted MES. Inorganic carbon (HCO3-) was efficiently converted into acetate (204.4 ± 0.5 mM with a coulombic efficiency of 96 ± 3% over 24 days operation) in a photo-assisted microbial electrosynthesis system (MES) using a urea-treated MnFe2O4/g-C3N4 cathode and the nonphotosynthetic bacteria Serratia marcescens Q1. The remarkable photocatalytic performance of MnFe2O4/g-C3N4 heterojunction was resulted from the charge transfer mechanism switch (from type II to Z-scheme) induced by the synergistic effect of oxygen vacancies and pyrrolic N after urea treatment. The increased pyrrolic N was conductive to photoinduced electron transfer while the oxygen vacancies provided a higher fraction of surface-active sites for H2 evolution, which was metabolized in-situ with bicarbonate by S. marcescens Q1 to yield acetate via the Wood–Ljungdahl pathway. This study provides a simple and feasible strategy for switching the photocatalytic charge transfer in a spinel-based heterojunction and offers new insights for ingeniously synthesizing photocatalysts with high CO2 conversion in MES.

Supplementary information files for Probing the enhanced methanol electrooxidation mechanism on platinum-metal oxide catalyst Pt-metal oxide nanocomposites are classified as an alternative promising catalyst besides Pt-Ru nanoalloys for electrochemical methanol oxidation reaction (MOR), and yet the relevant enhancement mechanism for MOR remains largely elusive in terms of catalyst functions and reaction pathways. Herein, interface-rich Pt-SnO2 nanoflakes supported on reduced graphene oxide have been prepared and employed as a model catalyst for such a study. X-ray photoelectron spectroscopy and X-ray absorption spectroscopy measurements reveal significant electronic structure modification on Pt in contact with SnO2, concomitant with enhanced MOR. In-situ surface enhanced infrared absorption spectroscopy and on-line differential electrochemical mass spectrometry measurements indicate that the non-CO pathway is selectively enhanced on Pt-SnO2 compared to the CO pathway which prevails on Pt. DFT calculations reinforce that this electronic structure manipulation favors the non-CO reaction pathway on Pt-SnO2.
