In the presence of OH−, the reaction can be shown by the following equations27–30: SbCl3 + H2O → SbOCl ↓ + 2HCl (1) 4SbOCl + H2O → Sb4O5Cl2 ↓ + 2HCl (2) NH4OH + HCl → NH4Cl + H2O (3) 2SbOCl + 2NH4OH → Sb2O3 + 2NH4Cl + H2O (4) Sb4O5Cl2 + 2NH4OH ...
Then, hydrochloric acid (7 mL, 2 M, HCl, Daejung, Korea) and polyvinylpyrrolidone (0.80 g, PVP, Sigma-Aldrich, China) were added and the mixed solution was stirred for 20 min. After stirring, the solution was transferred into a Teflon-lined steel autoclave (200 mL capacity) and ...
Introduction Hydrogen (H2) production has been achieved using different processes such as hydrocarbon reforming, photocatalytic generation, biodigestion, water thermolysis and water electrolysis [1,2]. Water electrolysis (WE) is one of the most preferable processes since pure H2 can be obtained with ...
