Oxygen-doped Sn₁₇Sb₆S₂₉ bimetal oxysulfide catalysts for efficient reduction of organic pollutants and hexavalent chromium in the dark

Abstract

Novel oxygen-doped Sn17Sb6S29 bimetal oxysulfide catalysts (labeled as SnSbOS) were successfully synthesized by a facile method via adjusting the H2O2 amount.

Synergistic vacancy defects and bandgap engineering in an Ag/S co-doped Bi2O3-based sulfur oxide catalyst for efficient hydrogen evolution

“…7a, and the current density showed no obvious change, indicating that Ag/S–Bi 2 O 3 -3 has good electrochemical stability. 58 All the above data show that the Ag/S–Bi 2 O 3 -3 catalyst is relatively stable. Similarly, Fig.…”

Synergism of heterovalent valence state and oxygen vacancy defect engineering in Co/S co-doped TiO2 for nitrogen photoreduction to ammonia

“…The EPR signal of CoTiOS-3 is much higher than that of TiOS or Co/TiO 2 , indicating that Co/S co-doping can induce more oxygen vacancies and capture more electrons. 51,52…”

Photocatalytic fixation of nitrogen to ammonia with a Ce/S co-doped TiO2 catalyst: synergistic tuning of heterovalent metal states and oxygen vacancy defects

“…The electro-reduction and electro-oxidation current densities of ferrous/ferrocyanide redox pairs did not signicantly decrease aer 100 cycles of operation. Meanwhile, the cathode and anode potentials remain relatively stable, indicating the electrochemical stability of TiCeOS 66. 3.6.…”
