Synthesis of mesoporous Bi@Bi2O3 and NOx photocatalytic oxidation mechanism. Uniform mesoporous Bi@Bi2O3 nanospheres were fabricated by HCl–ethanol chemical etching at low temperature, which increased the NO removal efficiency (16%) and inhibited toxic NO2 generation (3%) under visible light irradia...
