As an important compound in various industries and metabolic processes the human body, high concentrations of hydrogen peroxide (H2O2) can cause serious injuries to humans other organisms. Thus, it is great significance develop a rapid, sensitive, practical method for detection H2O2. Herein, carbon quantum dot-mediated CoAl-layered double hydroxide (CQDs/CoAl-LDH) was decorated on hematite (α-Fe2O3) photoelectrode via simple one-pot hydrothermal method. The resultant CQDs/CoAl-LDH/α-Fe2O3 exhibited excellent photoelectrochemical (PEC) sensing toward H2O2 with sensitivities 92.10 39.27 μA mM–1 cm–2 linear range 0.001–0.9 0.9–2 mM, respectively, low limit (0.02 μM, S/N = 3) at 0 V vs SCE, as well good selectivity, stability, reproducibility, reliability. investigation mechanism revealed that CQDs could not only mediate growth CoAl-LDH expose active sites but also improve electroconductivity facilitate charge transfer, while rapidly extract photogenerated holes separation provide catalytic oxidation. synergistic effect significantly boosted PEC activity α-Fe2O3 strategy boosting performance importance semiconductor photoelectrodes.
