A BiVO/FeO heterojunction for non-enzymatic photoelectrochemical (PEC) determination of hydrogen sulfide (HS) is reported. The BiVO/FeO heterojunction promoted the separation of photo-generated carriers, reduced electron-hole recombination, and thus improved electron collection and photocurrent. The proposed BiVO/FeO/FTO sensor exhibited a linear range of 1-500 μM and a detection limit of 0.51 nM HS. In addition, high selectivity, good reproducibility, and stability were obtained for HS sensing. The detection of HS in water and serum samples demonstrated its feasibility. This work provides a new strategy to detect and understand the bio-function of HS in the biological environment.
报道了一种用于非酶光电化学（PEC）测定硫化氢（HS）的BiVO/FeO异质结。BiVO/FeO异质结促进了光生载流子的分离，减少了电子-空穴复合，从而改善了电子收集和光电流。所提出的BiVO/FeO/FTO传感器对HS的线性范围为1-500 μM，检测限为0.51 nM。此外，该传感器在HS传感方面具有高选择性、良好的重现性和稳定性。对水和血清样品中HS的检测证明了其可行性。这项工作为检测和理解生物环境中HS的生物功能提供了一种新策略。
