H2S-responsive performance of the Bi:Cu2O@HA NPs. A Schematic diagram of the reaction of Bi:Cu2O@HA NPs with NaHS. B SEM image. C XRD pattern of Bi:Cu2O@HA after reaction with NaHS. D Absorption of Cu2O@HA and Bi:Cu2O@HA NPs before and after reaction with NaHS. E Plots of ΔT vs. time for Cu2O@HA + NaHS and Bi:Cu2O@HA + NaHS under 808-nm laser irradiation (1 W/cm2). F Plots of ΔT vs. time for Bi:Cu2O@HA (0.5 mM) + NaHS (4 mM) during six cycles of irradiation (1 W/cm2)
